Cranial nerve (CN) II is also known as the optic nerve, which carries visual stimuli to the brain. CN I is the olfactory nerve and it allows for the detection of odors. CN III is the oculomotor nerve, which allows the eyeball to move. CN IV is the trochlear nerve, which helps rotate the eye inferiorly and laterally. 

The common carotid is an artery that supplies blood to the head and neck. The internal jugular is the vein that drains blood from the head and neck. The brachial artery provides blood to the arm. The superior vena cava is a large vein that returns blood to the heart from the head and arms. 

The great saphenous vein is responsible for draining the blood from the legs. The femoral artery supplies blood to the legs. The inferior vena cava returns blood from the legs and abdomen to the heart. The pulmonary trunk bifurcates into the right and left pulmonary arteries, which bring oxygen-poor blood to the lungs, where it becomes oxygenated.

The interior of any hollow organ is called its lumen. A lumen may be completely or partially filled with air or fluid. All of the answer choices are specific examples of lumens.

The trigeminal nerve is cranial nerve (CN) V, it has both sensory and motor functions including sensation of the face and scalp, and control of the muscles of mastication. CN XI is the accessory nerve, which has only motor functions, and innervates the muscles of the lateral and posterior neck. CN VI is the abducens nerve, which is a motor nerve that innervates the lateral rectus and controls eye movements. CN I is the olfactory nerve and involves the sense of olfaction.

The triceps brachii is innervated by the radial nerve, which comes from the posterior cord of the brachial plexus. Accordingly, damage to the posterior cord would disrupt function of the triceps brachii, among other muscles. Lumbricals III and IV, and the flexor carpi ulnaris are innervated by the ulnar nerve, which comes from the medial cord of the brachial plexus. The biceps brachii is innervated by the musculocutaneous nerve, which comes from the lateral cord of the brachial plexus. The serratus anterior is innervated by the long thoracic nerve, which is a pre-plexus nerve.

All of the arteries listed, are coronary arteries, or branches of coronary arteries, which supply blood to the myocardium. The coronary sinus is a group of veins, so it drains blood from the myocardium, rather than supplying it.

Cranial nerves IX and X, as well as the inferior petrosal and sigmoid sinuses pass through the jugular foramen, while cranial nerve VII passes through the internal auditory meatus.

Purkinje cells are found in the cerebellum, and are not part of the cardiac conduction system. All other answer choices are part of the cardiac conduction system, which terminates in the Purkinje fibers.

The epidermis does not have direct blood supply; all nutrients that feed cells within the epidermis come from the dermis. The hypodermis lies beneath the dermis and consists of loose connective tissue such as fat. The hypodermic layer also contains blood vessels, lymph vessels, and sweat glands.
