Example Question #91 : Identifying Nerves And Blood Vessels
The medial cord of the brachial plexus branches and ultimately becomes which two nerves?
Radial and axillary
Axillary and ulnar
Median and musculocutaneous
Median and ulnar
Median and ulnar
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.
Example Question #665 : Gross Anatomy
The musculocutaneous nerve arises from which cord of the brachial plexus?
Lateral cord
Middle cord
Posterior cord
Medial cord
Lateral 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.
Example Question #666 : Gross Anatomy
Which of the following arteries come as a pair?
Subclavian arteries
Splenic arteries
Intercostal arteries
Adrenal arteries
Adrenal arteries
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.
Example Question #92 : Identifying Nerves And Blood Vessels
Which of the following arteries does not branch off of the celiac trunk?
Common hepatic artery
Right gastric artery
Left gastric artery
Splenic artery
Right gastric artery
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.
Example Question #93 : Identifying Nerves And Blood Vessels
The deep femoral artery gives rise to the medial and lateral branches of which of the following arteries?
Femoral circumflex
Femoral
Tibial
Iliac
Femoral circumflex
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.
Example Question #94 : Identifying Nerves And Blood Vessels
The left common carotid artery branches into which two arteries?
Internal and external carotid arteries
Maxillary and facial arteries
External carotid and superior laryngeal arteries
Superior and inferior thyroid arteries
Internal and external carotid arteries
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.
Example Question #670 : Gross Anatomy
The tubular artery supplies which compartment of the leg?
Lateral
Medial
Superficial
Deep
Lateral
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.
Example Question #95 : Identifying Nerves And Blood Vessels
The left and right gastro-mental arteries supply what structure?
Lesser curvature of the stomach
Spleen
Right quadrant of the liver
Greater curvature of the stomach
Greater curvature of the stomach
The correct answer is the greater curvature of the stomach. This is because the greater curvature is connected to the greater omentum, a large fold of peritoneum that covers the organs in the abdomen. The lesser curvature of the stomach is supplied by the left and right gastric arteries, the spleen is supplied by the splenic artery, and the right quadrant of the liver is supplied by the right hepatic artery.
Example Question #672 : Gross Anatomy
At which point in the leg does the femoral artery become the political artery?
Adductor magnus
Adductor brevis
Adductor hiatus
Sciatic notch
Adductor hiatus
The correct answer is the adductor hiatus. This is the "hole" in the adductor magnus muscle of the thigh where the femoral artery becomes the popliteal artery. Both the adductor magnus and braves are muscles and the sciatic notch is located posteriorly in the ilium.
Example Question #96 : Identifying Nerves And Blood Vessels
Which of the following arteries does not supply blood to a part of the brain stem?
Posterior inferior cerebellar artery (PICA)
Anterior inferior cerebellar artery (AICA)
Anterior cerebral artery
Basilar artery
Anterior cerebral artery
The anterior cerebral artery supplies the deep portion of the frontal lobe, but it does not supply the brainstem. The AICA supplies a portion of the lateral pons. The PICA supplies a portion of the lateral medulla. Branches of the basilar artery supply the medial and lateral pons, as well as the midbrain.
