Flashcards in (final) Lecture 13 (5/23/16) PT. 2 Deck (33):
Renal arteries are branches of what?
Branches of the renal arteries eventually give rise to...
Kidneys are drained by...
Which dumps into...
inferior vena cava
Sympathetic innervation of kidneys:
T5-T9 & T10-T11
Sympathetic function of kidneys:
may constrict the blood flow to afferent arterioles which decreases overall kidney output
Parasympathetic innervation of kidneys:
synapse on target organ
may increase blood flow to kidneys
increase kidney filtration function
Vascularization of bladder
A: superior and inferior vesicle arteries
V: superior and inferior vesicle veins
Sympathetic innervation of bladder:
synapse in inferior mesenteric plexus and postgnaglionics leading to hypogastric plexus
Sympathetic function of bladder:
-inhibit constriction of muscular wall of bladder (detrusor)
Parasympathetic innervation of the bladder:
pelvic nerve S2-4
synapse on bladder wall
Parasympathetic function of bladder:
-stimulate constriction of muscular wall of bladder (detrusor)
Which germ layers will usually form epithelia?
ectoderm and endoderm
Nerve cells that produce hormones and secrete them into the bloodstream are called...
Where are neurosecretory cells found?
Where does the pituitary gland sit?
What bone contains the sella turcica?
in the medial cranial fossa of the sphenoid bone
Two lobes of pituitary:
Anterior pituitary and posterior pituitary
The stalk that connects the hypothalamus and the pituitary:
The hypothalamus is derived from...
The hypothalamus is an outgrowth of...
The name of the posterior pituitary is...
And is an outgrowth of...
The name of the anterior pituitary is...
And is an outgrowth of...
roof of mouth
Innervation of hypothalamus and pituitary gland:
"innervated by the brain"
Some hypothalamic neurons secrete what?
What do neurohormones do?
they go down infundibulum and terminate near capillaries serving posterior pituitary
Hypothalamus and pituitary gland...
A: circulus arteriosus cerebri
V: cavernous venous sinus
Hypothalamic hormone pathway (released by neurohypophysis):
enclosed in vesicles that move down axon and accumulate near terminal ends that are close to the posterior pituitary's capillaries
In response to an action potential, hormones are released from vesicles into...
What are manufactured in the hypothalamus but released in the posterior pituitary?
Oxytocin and vasopressin re manufactured where? Released where?
in the posterior pituitary
Hypothalamic hormone pathway (released by adenohypophysis):
enclosed in vesicles that move down axon and accumulate near terminal ends that are close to pituitary stalk
