The correct answer is the oculomotor nerve. In this case we are looking for a motor nerve that has something to do with the eye, letting us rule out both the olfactory (sensory) and facial (sensory and motor, but not of the eye) nerves. That leaves the oculomotor and optic nerves, however the optic nerve is solely sensory while the oculomotor nerve is a motor nerve.

The posterior cord of the brachial plexus gives rise to the nerves in the deep compartment of the upper arm. Those are the radial and axillary nerves. The musculocutaneous nerve comes from the lateral cord. The median nerve comes from the lateral and medial cords. The ulnar nerve comes from the medial cord.

C8 and T1 merge to give rise to the inferior trunk of the brachial plexus. They are the most inferior roots of the brachial plexus, so it would make sense that they feed into the inferior trunk.

The medial cord of the brachial plexus gives rise to two nerves in the superficial compartment of the upper arm. There are three possible nerves: musculocutaneous, median, and ulnar. The musculocutaneous nerve comes from the lateral cord, making the correct answer the median and ulnar nerves. The radial and axillary nerves come from the posterior cord.

The correct answer is the lateral cord. The medial cord gives rise to the ulnar and median nerves, the posterior cord feeds nerves in the deep compartment of the upper arm, and the middle cord is not a cord, it is a trunk.

In the body, certain arteries come in pairs, meaning they have either a left and right, or an internal and external. Of the ones listed here, only the adrenal arteries have both a left and right, making it the correct answer. There is only one artery for each of the other answer choices.

The celiac trunk is a branch off of the abdominal aorta which is partially responsible for the circulation of blood to the abdominal organs. There are three branches of the celiac trunk which are as follows: left gastric, common hepatic, and splenic arteries. That means the correct answer would be the right gastric artery which does not come from the celiac trunk, but instead anastomoses with the left gastric artery to supply the lesser curvature of the stomach.

For this question we are looking for arteries which are inferior to the pubic bone, yet superior to the tibia and fibula, which leave us with either the femoral artery or femoral circumflex artery. The correct answer is the pair of femoral circumflex arteries which supply muscles in the deep compartment of the thigh. The femoral artery does not have a medial or lateral branch.

The left common carotid artery gives rise to the internal and external carotids. While each of the other answer choice supply an area of the face or neck, they do not arise from the common carotid artery. In fact, each of these arteries arise from either the internal or external carotid arteries.

The fibular artery is one of three arteries that arise from the popliteal artery. The other two are the anterior and posterior tibial arteries which supply the anterior and posterior compartments respectively. Therefore the correct answer is the lateral compartment because there is no medial compartment.
