19
Q

T/F: The pars distalis and the pars nervosa are the glandular parts of the pituitary.

A

False - neurohypophysis is NOT glandular. Adenohypophysis is

A
X = basophil
Y = glycoprotein (FSH, LH, TSH) or ACTH
22
Q

(X) artery gives rise to primary capillary plexus, which surrounds (Y) structure of pituitary.

A
X = superior hypophyseal a
Y = median eminence
23
Q

(X) artery gives rise to secondary capillary plexus, which surrounds (Y) structure of pituitary.

A
X = superior hypophyseal a
Y = pars distalis
24
Q

(X) artery gives rise to branches, which supply pars nervosa.

A

X = inferior hypophyseal

T/F: Infundibular stalk is part of neurohypophysis.
True
30
Unlike sinusoids, (X) arteries originate (above/below/within) adrenal cortex capsule and have which course?
X = medullary (or long cortical) Below; Deliver blood directly to medullary cap's without picking up hormones from cortex
31
Which region(s) of adrenal gland contains lipid droplets?
All regions of cortex (but not medulla)
32
Adrenal (medulla/cortex) contains cells high in sER. And rER?
Cortex (all regions); | Medulla high in rER
