Hey, everyone. Let's take a look at this question together which of the following muscles is responsible for the abduction of the big toe. Is it answer choice. A the flexor digitorum longus, answer choice B the abductor hallucis Brevis, answer choice C the Rectus Abdominus or answer choice. D the pronator Teres. Let's work this problem out together to try to figure out which of the following answer choices. It's the name for the muscle that is responsible for the abduction of the big toe. So in order to solve this question, we have to recall what muscles are responsible for abduction and what abduction is. Well, we know that the muscle responsible for abduction is a type of abductor muscle. And since we are talking about the abduction of the big toe, we are looking for an abductor muscle that helps move the big toe away from the midline of the body. And looking at our answer choices, we can see that answer choice B says the Abductor Hauss Brevis, which is a type of abductor muscle and is the muscle responsible for the abduction of the big toe. So answer choice, B. Abductor Huss Prevas is the correct answer. And we know that answer choice. AC and D are all incorrect. Since answer choice A is a flexor muscle which is responsible for the flexion of the toes. Answer choice C is an abdominous muscle which is a muscle in the abdominal region. And answer choice D is responsible for pronation of the forearm. So answer choice AC and D are all incorrect and answer choice B is the correct muscle responsible for the abduction of the big toe. I hope you found this video to be helpful. Thank you and goodbye.
