Video transcript

Everyone. Let's take a look at this question together which of the following muscles is correctly matched with its corresponding compartment. And we have four different muscles that we have to figure out which one has the correct corresponding compartment. So in order to solve this question, we have to determine which of the following answer choices as the correct muscle with its corresponding compartment. So starting off with answer choice A, we have the flexor digitorum brevis and it says that it is found in the posterior compartment of the leg. However, we note that the flexor digitorum brevis is actually found in the sole of the foot and not the posterior compartment of the leg. So answer choice A is an incorrect pair. Answer. Choice. B says that the gastrocnemius is found in the medial compartment of the thigh. However, we note that the gastrocnemius is found in the posterior compartment of the leg and not the medial compartment of the thigh. So that means that answer choice B is also incorrect since medial compartment of the thigh is an incorrect match answer choice C says the actor longus is found in the third muscle layer of the foot. However, we know that the actor Longus is actually found in the medial compartment of the thigh and not in the third muscle layer of the foot. So that means that answer choice C is also incorrect. Since third muscle layer of the foot is not the correct pair for the AUC Longus, which leaves us with the only remaining answer choice which is answer choice D the biceps femoris, which is found in the posterior compartment of the thigh, which is a correct match. So answer choice D is the correct answer. Since answer choices A B and C all contain incorrect corresponding compartments for their muscle. And answer choice D is the only one that is correctly matched. I hope you found this video to be helpful. Thank you and goodbye.
