Hey, everyone. Let's take a look at this question together which of the following muscles are not involved in gripping the ball and releasing it at the right moment. Is it answer choice? A, a Flexor poly Brevis, answer choice B A Doctor Poly. Answer choice C AINS poly or answer choice D Palmar and Tara. Let's work this problem out together to try to figure out which of the falling muscles are not involved in gripping the ball and releasing it at the right moment. So in order to solve this question, we have to recall which muscles are involved in gripping a ball and releasing it at the right moment. While looking at our answer choices, we know that the Flexor Polys Brevis, which is answer choice. A is involved in gripping the ball. Answer choice B the AUC Polys is also involved in gripping the ball and answer choice C the opening poly is also directly involved in gripping and releasing a ball, which means that answer choice A B and C are all incorrect. And the only muscle here that is not involved in gripping the ball and releasing it at the right moment is answer choice d the palmar Interra muscle. Since the palmar Interra muscles which are located in the palm of the hand are involved in the auction of the fingers towards the middle finger and are not directly involved in gripping and releasing a ball. I hope you found this video to be helpful. Thank you and goodbye.
