Bobby Ray McCollum (“defendant”) appeals from a judgment entered upon a jury verdict finding him guilty of first-degree murder. He was sentenced to life imprisonment without parole in the North Carolina Department of Correction. We find no error.
The State presented the following evidence at trial: on 30 August 2003, Willis McCollum (“Willis”), defendant’s brother, and Leon Evans (“Leon”), defendant’s first cousin, asked Priscilla McCollum Jennings (“Priscilla”), defendant’s sister and wife of the victim, Weldon Lamont Jennings (“Weldon”), if they could have a family cookout at Priscilla’s mother’s home. After Priscilla’s mother agreed and Leon and Willis bought the food, Priscilla, Weldon, Leon, and Willis all made their way to Priscilla’s mother’s home. After cooking for approximately thirty minutes, Willis stated he saw defendant coming and proceeded, along with Leon, to argue with defendant regarding mowing lawns that day. Defendant had a side business mowing lawns and had expected both Willis and Leon to assist him that day. Weldon apparently made a joke referencing the argument between defendant and Willis and Leon. Defendant threw up his hands and left the cookout. Twenty minutes later, defendant returned and according to Priscilla “he just came right *684around and put his hand on [Weldon’s] head and put the gun to [Weldon’s] head and pulled the trigger.” Priscilla grabbed her granddaughter, ran into the house, and called 911.
Deputy Sheriff Christopher Ross (“Deputy Ross”) testified.he responded to the 911 call. Upon arrival, Deputy Ross met with Willis and was told defendant shot Weldon. Sergeant Gary Summers (“Sergeant Summers”), who had known defendant for nearly thirty years, proceeded to defendant’s residence. Once apprehended by police, defendant stated “[h]ell, man, I shot him. I just meant to knock the s**t out of him with the gun, and it went off.” Police retrieved the gun used by defendant in the shooting from defendant’s home.
Defendant presented the following evidence at trial: Felicia McCollum (“Felicia”), defendant’s wife of 22 years, testified that in June of 1984, defendant’s brother, George, was shot and killed. The bullet, which was meant for defendant, went in defendant’s jaw and through his neck before it struck George. Defendant became very withdrawn, distant, and paranoid. Felicia also testified that one year later, defendant’s father fired a gun at him wounding his hand. Defendant and his father never spoke of the incident again and as a result, defendant carried around a tremendous amount of guilt once his father died. Finally, Felicia testified that in 1987 defendant’s eldest daughter was bom with a variety of congenital birth defects. This added to defendant’s financial stress and with it, marital stress, as a result of dividing his time between work and the hospital.
Dr. James Bellard (“Dr. Bellard”), an expert in forensic psychiatry, testified to the following: defendant had post-traumatic stress disorder (“stress disorder”); major depression; and cognitive disorder. Dr. Bellard traced the stress disorder to the events surrounding the shooting of defendant’s brother and explained how the stress disorder caused symptoms such as anxiety and irritability. Further, Dr. Bellard testified defendant’s depression had similar ingredients to that of defendant’s stress disorder. Due to the above medical diagnoses, Dr. Bellard testified “I don’t believe that [defendant] was able to form the specific intent to Mil [Weldon].” Dr. Bellard also stated “I think he wasn’t able to fully appreciate the ramifications, the results of his actions.”
At the conclusion of the trial, the jury returned a verdict finding defendant guilty of first-degree murder. The trial court sentenced defendant to life imprisonment without the possibility of parole. Defendant appeals.
*685I. Closing Argument:
Defendant argues the trial court erred in failing to intervene ex mero motu iri permitting the State to include prejudicial matters that existed outside the record in its closing argument. Defendant also argues the trial court erred in permitting the State to contend in its closing argument certain matters contrary to the law. We disagree.
a. No Objection-.
[1] “The standard of review when a defendant fails to object at trial is whether the [closing] argument complained of was so grossly improper that the trial court erred in failing to intervene ex mero motu.” State v. Trull, 349 N.C. 428, 451, 509 S.E.2d 178, 193 (1998). “In determining whether the prosecutor’s argument was . . . grossly, improper, this Court must examine the argument in the context in which it was given and in light of the overall factual circumstances to which it refers.” State v. Hipps, 348 N.C. 377, 411, 501 S.E.2d 625, 645 (1998) (emphasis added). “ ‘[T]he impropriety of the argument must be gross indeed in order for this Court to hold that a trial judge abused his discretion in not recognizing and correcting ex mero motu an argument which defense counsel apparently did not believe was prejudicial when he heard it.’ ” Id. (quoting State v. Johnson, 298 N.C. 355, 369, 259 S.E.2d 752, 761 (1979)).
In the instant case, the prosecutor said the following without objection from defendant.
We live in violent times. There have been many cold-blooded murders that seem to make no sense at all. And if you stop and think about it, you realize that. We’ve had presidents who were shot, who were assassinated. We’ve had 3,000 people in New York who were assassinated by the airplane flying into a building. Does it make any sense? Of course not. Is it rational[sic]? Certainly not. Is it murder? Absolutely.
And that’s what the defendant did in this case. He executed Mr. Jennings. The word assassinate, in Webster’s Dictionary, means a murderer who strikes suddenly and by surprise. The word assassinate means to murder by surprise, to attack, to murder by surprise attack.
In accordance with Hipps, supra, examining the closing argument in light of both the given context and factual circumstances, it is clear the trial court did not err in failing to intervene ex mero motu. First, the *686context for the prosecutor’s comments was to explain that defendant’s lack of a specific motive could not absolve him of responsibility for the criminal act. Defendant argued at trial because he lacked motive to murder Mr. Jennings, he also lacked the necessary premeditation and deliberation to commit first-degree murder. Second, the prosecutor’s reference to the World Trade Center attack was a reminder to the jury there is not always an explanation for why criminal actions occur, not an attempt to somehow equate defendant’s actions with those of terrorists on 11 September 2001. Furthermore, our Supreme Court has “held in numerous cases that argument of counsel must be left largely to the control and discretion of the presiding judge and that counsel must be allowed wide latitude in the argument of hotly contested cases.” State v. Monk, 286 N.C. 509, 515, 212 S.E.2d 125, 131 (1975) (citations omitted). Therefore, because the remarks by the prosecutor were not so grossly improper as to require intervention, we hold the trial court was correct in not intervening ex mero motu.
b. Objection•
[2] “The standard of review for improper closing arguments that provoke timely objection from opposing counsel is whether the trial court abused its discretion by failing to sustain the objection.” State v. Jones, 355 N.C. 117, 131, 558 S.E.2d 97, 106 (2002). “In order to assess whether a trial court has abused its discretion when deciding a particular matter, this Court must determine if the ruling ‘could not have been the result of a reasoned decision.’ ” Id. (quoting State v. Burrus, 344 N.C. 79, 90, 472 S.E.2d 867, 875 (1996). Nevertheless, because “[arguments of counsel are largely in the control and discretion of the trial court[,] [t]he appellate courts ordinarily will not review the exercise of that discretion unless the impropriety of counsel’s remarks is extreme and is clearly calculated to prejudice the jury.” State v. Huffstetler, 312 N.C. 92, 111, 322 S.E.2d 110, 122 (1984) (emphasis added).
In the instant case, the prosecutor said the following:
Now, indeed, members of the jury, you folks heard a lot more, seen a lot more and know a lot more about this case than Dr. Bellard knows. You are in a much better position to assess the defendant’s state of mind and his actions than the doctor. And not to mention the fact that Dr. Bellard kept talking about terms of psychiatry, which do not apply as opposed to legal terms which do. You must decide does the evidence prove....
In accordance with Huffstetler, supra, the prosecutor’s comments were neither extreme nor calculated to prejudice the defendant. In fact, the *687prosecutor apprised the jury that Dr. Bellard’s testimony could not impact or influence their evaluation of whether or not defendant had the premeditation and deliberation to murder Mr. Jennings. This was not done, as argued by defendant, to suggest “the jury should find that [defendant] had premeditation and deliberation because Dr. Bellard never testified that he did not.” The prosecutor’s argument was not prejudicial towards defendant but rather an accurate statement regarding the law. See State v. Daniel, 333 N.C. 756, 763, 429 S.E.2d 724, 729 (1993) (stating “we have held that testimony by medical experts relating to precise legal terms such as premeditation or deliberation . . . should be excluded.”) Moreover, error “is prejudicial only upon a showing by the defendant that there is a reasonable possibility that, had the error in question not been committed, a different result would have been reached at the trial.” State v. McEachin, 142 N.C. App. 60, 70, 541 S.E.2d 792, 799 (2001) (citation and internal quotation marks omitted) (emphasis added). Though defendant argues this portion of the prosecutor’s closing argument was unfair and ultimately prejudicial, he fails to clearly illustrate why the result would have been any different absent such remarks. We discern no abuse of discretion by the trial court and consequently, defendant’s assignments of error pertaining to the State’s closing argument are overruled.
A. Jury Instruction not Given:
[3] Defendant next argues the trial court erred in refusing to instruct the jury that a medical expert could not testify to legal terms. We disagree. Here, defendant’s entire argument is premised on the proposition that the prosecutor’s closing argument, informing the jury that Dr. Bellard’s testimony could not impact or influence their assessment of whether or not defendant had the premeditation and deliberation to murder Mr. Jennings, was error. That argument was refuted above and remains equally unavailing here. This assignment of error is overruled.
III. Jury Instruction Given:
[4] Defendant argues the trial court erred in not reading the entire jury instruction listing all seven circumstances whereby proof of defendant’s premeditation or deliberation could be inferred regarding the unlawful killing of Mr. Jennings. Defendant contends though the trial court charged the jury in accordance with Pattern Jury Instruction 206.13, the court’s rendition excluded one of the circumstances from the list of seven circumstances and this exclusion constituted reversible error. We disagree.
*688Though “[a] trial court must give a requested instruction that is a correct statement of the law and is supported by the evidence^] [t]he trial court need not give the requested instruction verbatim [for] an instruction that gives the substance of the requested instructions is sufficient.” State v. Conner, 345 N.C. 319, 328, 480 S.E.2d 626, 629 (1997) (citations omitted). In the instant case, not only did the actual instruction by the trial court provide the substance of what defendant requested, but defendant’s counsel declared the desired instruction was inapplicable to the facts of this case.
Pattern Jury Instruction 206.13 reads as follows:
Neither premeditation or deliberation are usually susceptible of direct proof. They may be proved by circumstances from which they may be inferred, such as the lack of provocation by the victim, conduct of the defendant before, during, and after the killing, threats and declarations of the defendant, use of grossly excessive force, infliction of lethal wounds after the victim is felled, brutal or vicious circumstances of the killing, [and] manner in which or the means by which the killing was done.
The actual instruction.given by the trial court excepted the circumstance of “infliction of lethal wounds after the victim is felled.” Thus, six of the seven circumstances listed as being indicative of premeditation and deliberation were given to the jury. This appears to follow the prescription of Conner, supra, that so long as the “substance” of the requested instruction is provided, such an instruction is sufficient. Moreover, in arguing for inclusion of the excepted circumstance, defendant’s counsel asserted “I realize it did not happen in this case, the infliction of lethal wounds after the victim was felled, but all the others were read.” The trial court acknowledged excluding this circumstance stating “I made the determination . .. there was evidence to support all those circumstances, except infliction of lethal wounds after the victim has felledf.]” Consequently, since defendant’s counsel admitted both the facts and the evidence did not warrant inclusion of the requested circumstance, the “substance” of his request was in fact given. We overrule this assignment of error.
[5] The remainder of defendant’s assignments of error were not briefed on appeal and thus, according to N.C. R. App. P. 28(b)(6) (2005), they are abandoned.
No error.
