Anatomy quiz

Question 1

Tunica albuginea vs tunica vaginalis

Answer 1

T albuginea- fibrous tissue that overlies corpus spongiosum and corpora cavernosa of the penis

T vaginalis- tissue that remainvs overlying the testis and epididymis- leads to hydrocele if processus vaginalis does not obliterate

Question 2

Cancer in the 3rd part of the duodenom can invade which organ

Answer 2

Superior mesenteric artery

Uncinate process of pancreas

Question 3

What dopaminergic pathway correlates dopamine to prolactin

Answer 3

Tuberinfundibular dopaminergic pathway

Neuroleptics blocks the dopamine here leading to hyperprolactinemia

Question 4

Piriform recess

Answer 4

Small cavity on either side of laryngeal orifice
Surrounded medial by aryepiglottic folds and laterally by thyroid cartilage and thyrohyoid membrane

Underneath piriform recess is the Internal branch of the superior laryngeal nerve (CNX)

Sensory nerve for afferent limb of COUGH reflex

Carry sensation from the mucosa superior to the vocal cords

Question 5

Femoral nerve descend through which structure

Answer 5

Psoas major muscle- emerges laterally between psoas and iliacus muscle

Femoral nerve mononeuropathy happens due to trauma, compression from hematoma, abscess, stretch injury, ischemia

Weakness in quadriceps and weakening iliopsoas, reflex is deminished and they have difficulty with stairs. Also get “knee buckling” and sensory loss of anterior medial thight and medial leg.

11th, 12th rib

Question 7

9, 10, 11 left rib hit what structure

Answer 7

Spleen

Question 8

Right 8-11 rib fracture

Answer 8

Liver

Question 9

Rib 1-6 rib fracture

Answer 9

Visceral pleura

Question 10

Crushing abdominal trauma

Answer 10

Pancreas

Question 11

Lesion of Glossopharyngeal nerve

Answer 11

Loss of gag reflex (afferent), loss of sensation in the upper pharynx, posterior tongue, tonsils, and middle ear cavity, loss of taste on the posterior 1/3 of tongue

Question 12

3 heart pacemaker lead placement

Answer 12

RAtrium
RVentricle
Atrioventricular groove - 3rd lead goes here to get to the left ventricle- it goes through coronary sinus which lies in the posterior AV groove

Question 13

Superior gluteal

Answer 13

Innervates the gluteus medius, gluteus minimus, and tensor fasciae latae muscles

Trandelenburg sign (hip drop of opposite side) when standing

Gluteus medius lurch when walking (lean to bad side)

Question 14

Nursemaid elbow

Answer 14

Annular ligament displacement

occurs by pulling the arm

Question 15

Ulnar collateral joint injury

Answer 15

Baseball players

Tommy John surgery (reconstruction)

Question 16

Anterior heart surface

Answer 16

Mainly Right VEntricle

Question 17

Low frequency hearing

Answer 17

Near helicotrauma of chochlea

Question 18

HIgh frequency hearing

Answer 18

Base of cochlea near oval and round window

Question 19

Body satiety center

Answer 19

ventromedial nucleus of hypothalamus

because you get fat in the ventral and medial portion of your body when VMN is lesioned

Question 20

Spinal cord level

Answer 20

Proximal is ovoid and increasing amounts of white matter

Thoracic and early lumbar T1-L2 has lateral grey matter horn
Lower cervical and lumbrosacral region have large ventral horns

Question 21

Bursitis from kneeling too much

Answer 21

Prepatellar bursitis

Question 22

Nerve near inferior thyroid artery

Answer 22

Recurrent laryngeal

Question 23

Superior thyroid artery is near which nerve

Answer 23

external branch of the Superior laryngeal nerve- innervates cricothyroid

internal branch= sensory above the vocal nerve

Question 24

Chorda Tympani

Answer 24

Branch of the facial nerve that does taste for anterior 2/3 of tongue
