Is an afferent or efferent pupillary defect described as B/L pupillary constriction when light is shined in the unaffected eye and B/L paradoxical dilation when light is shined in the affected eye?
Afferent pupillary defect (CN II lesion); in an efferent pupillary defect (CN III), B/L constrict when light is shined in the unaffected eye and consentual pupil constriction occurs when light is shined in the affected eye.
What is the name of the spinal cord passing within the subarachnoid space and forming the spinal nerves that exit the lumbar and sacral foramina?
Cauda equina
Name the laryngeal muscle described by the following: • Pulls the arytenoids cartilages closer to the thyroid, relaxing the vocal ligaments and thereby decreasing the pitch
Thyroarytenoid muscles
Name the laryngeal muscle described by the following: • Tenses the vocal ligaments, increasing the distance between the cartilages, thereby increasing the pitch
Cricothyroid muscles
Name the laryngeal muscle described by the following: • Adducts the vocal ligaments, closes the air passageway during swallowing, and allows phonation
Lateral cricoarytenoid muscles
Name the laryngeal muscle described by the following: • Only muscle to abduct the vocal cords
Posterior cricoarytenoid muscles

Right brachiocephalic artery
Name the correct artery. • The left recurrent laryngeal nerve passes around it.
Arch of the aorta
The inferior mesenteric artery drains into it.
The splenic vein
Are the quadrate and caudate lobes of the liver functionally part of the left or right lobe?
Functionally they are part of the left lobe of the liver because they receive their blood supply from the left hepatic artery. Anatomically they are considered part of the right lobe of the liver.
What bones make up the acetabulum?
Pubis, ilium, and ischium
What is the anatomic positioning of the right and left gastric nerve plexus of the esophagus as they pass through the diaphragm?
LARP: Left goes Anterior and Right goes Posterior (because of the rotation of the gut; remember your embryology!)
