Example Question #35 : Identifying Nerves And Blood Vessels
Which of the following vessels does not come from the celiac trunk?
Left gastric artery
Common hepatic artery
Renal artery
Splenic artery
Renal artery
The celiac trunk supplies blood to the stomach, liver, spleen, pancreas, and duodenum. It is located in the abdominal cavity above the left and right renal arteries. The renal artery branches off directly from the abdominal aorta.
Example Question #611 : Human Anatomy And Physiology
What is the function of the oculomotor nerve?
Vision
Eye movement
Innervation of the lateral rectus muscle
Innervation of the superior oblique muscle
Eye movement
The function of the oculomotor nerve is eye movement. It controls eye movement through innervating the superior, medial, and inferior rectus muscles, the inferior oblique, levator palpebrae and the pupillary and ciliary muscles. The optic nerve controls vision and the superior oblique and lateral rectus muscles are innervated by the trochlear and abducens nerves, respectively.
Example Question #37 : Identifying Nerves And Blood Vessels
Which blood vessel supplies the brain?
External carotid artery
Internal jugular vein
External jugular vein
Internal carotid artery
Internal carotid artery
Veins take blood back to the heart, and in all but one case (pulmonary veins), they carry oxygen-poor blood. The external carotid artery supplies the face. Only the internal carotid artery goes directly up to supply the brain.
Example Question #612 : Human Anatomy And Physiology
Which of the following is not a branch off of the human aortic arch?
Right common carotid artery
Brachiocephalic trunk
Left subclavian artery
Left common carotid artery
Right common carotid artery
The three branches off of the human aortic arch are the brachiocephalic trunk, the left common carotid artery, and the left subclavian artery. The brachiocephalic trunk bifurcates into the right subclavian artery and the right common carotid artery.
Example Question #613 : Human Anatomy And Physiology
Which of these cranial nerves has both sensory and motor function?
Optic
Vestibulocochlear
Glossopharyngeal
Trochlear
Glossopharyngeal
Of these choices only the glossopharyngeal nerve has both motor and sensory functions. The trochlear nerve is motor and the optic and vestibulocochlear nerves are both sensory. To help remember the cranial nerves and their respective numbers the following mnemonic may be helpful: Oh Oh Oh, To Touch And Feel Very Green Vegetables, AH. In order from one to twelve: Olfactory, Optic, Oculomotor, Trochlear, Trigeminal, Abducens, Facial, Vestibulocochlear, Glossopharyngeal, Vagus, Accessory, Hypoglossal.
Example Question #614 : Human Anatomy And Physiology
Which of the following nerves only have sensory functions?
Sural nerve
Femoral nerve
Suprascapular nerve
Common fibular nerve
Median nerve
Sural nerve
While the other nerves do provide cutaneous sensation, they also innervate muscles in the upper and lower extremities. Of the nerves listed, the sural is the only that only has sensory functions; it provides cutaneous sensation to the lateral lower leg.
Example Question #615 : Human Anatomy And Physiology
Which upper extremity nerve only has motor function?
Long thoracic nerve
Axillary nerve
Median nerve
Musculocutaneous nerve
Suprascapular nerve
Long thoracic nerve
While all of these nerves have motor functions, the long thoracic nerve is the only that has motor function only; it innervates the serratus anterior muscle. The suprascapular nerve provides sensation to portions of the glenohumeral and acromioclavicular joints, the musculocutaneous nerve provides cutaneous sensation to the lateral forearm (as the lateral antebrachial cutaneous nerve), the axillary nerve provides cutaneous sensation to the lateral shoulder, and the median nerve supplies cutaneous sensation to the palmar surfaces of the lateral hand, index, and ring fingers.
Example Question #616 : Human Anatomy And Physiology
The deep lateral rotators of the hip are important for maintaining hip stability. Which one of them is innervated by a branch of the obturator nerve?
Quadratus femoris
Obturator internus
Obturator externus
Gemellus superior
Piriformis
Obturator externus
Of these muscles, the obturator externus is the only one innervated by the obturator nerve. Also, the adductor magnus is innervated by the posterior fibers of the obturator nerve. The obturator internus is innervated by the nerve to the obturator internus. The other deep lateral rotators are innervated by nerves named after the muscles they innervate (e.g. nerve to the piriformis).
Example Question #617 : Human Anatomy And Physiology
Which of the following is not a branch of the facial nerve?
Mandibular
Maxillary
Cervical
Zygomatic
Posterio auricular
Maxillary
There is no maxillary branch of the facial nerve. The branches of the facial nerve are as follows: temporal, zygomatic, buccal, mandibular, cervical, posterior auricular. Recall that the facial nerve is also known as cranial nerve VII.
Example Question #618 : Human Anatomy And Physiology
Which of the following blood vessels does not originate from the internal iliac artery?
Inferior gluteal artery
Superior gluteal artery
None of these
Femoral artery
Obturator artery
Femoral artery
The femoral artery is a continuation of the external iliac artery. The super and inferior gluteal arteries, and the obturator artery are branches of the internal iliac artery.
