A&P Lab practical Flashcards
(35 cards)
Organs innervated by SYM
exclusively inervates
- Most B. vessels
- sweat glands
- Adrenal glands (medulla)
- Piloercetor
Organs innervated by PARA
Lacrimal gland
Major nerves of the ANS
Splanchnic
Vagus
vagus
Major nerve Carries about 90% of pre fibers travels down the -cardiac plexus -Pulmonary plexus -Esophageal plexus (swallowing)
Anterior pituitary
Very vascular Secretes FSH LH ACTH PRL (target mammary gland) GH TSH
Posterior pituitary
Neural
releases hormones from un-myelinated axon
Secretes
ADH-pumps blood press back up (allows H2O ret)
OT- (Oxytocin) Contraction of smooth muscle during labor (+FB)
thyroid gland
made up of thyroid follicles
surrounded by follicular cells
secrete TG (storage form of TH)
Surrounded by parafollicular cells
adrenal cortex
Nucleus of Adrenal glands
secretes
-E
-NE
adrenal medulla
endocrine gland and ganglion of SYM. Secrete -E -NE -Dapamine
pancreas
Secrete Insulin (beta cell) Glucagon (alpha cell) acini cells- regulation of glycemia- blood glucose con.
parathyroid
4 located in the posterior surface of the thyroid
Secrete parathyroid hormone PTH
-response to hypocalcemia
Anterior pit. secretes
FSH LH ACTH PRL (target mammary gland) GH TSH
posterior pit secretes
ADH-pumps blood press back up (allows H2O ret)
OT- (Oxytocin) Contraction of smooth muscle during labor (+FB)
Zona Glomerulosa
outer most layer
Releases Mineralocorticoids (aldosterone)
Restricts loss of H2O, NA in urine, Sweat, digestive tract, saliva
Zona Fasciculata
Middle (Largest Layer)
Glucocorticoids (cortisol)
Stimulated by ACTH
Zona Reticularis
Closest to medulla Secretes Androgens (Male sex hormone)
Thyroid gland cells
thyroid follicle
Follicular cells- TH (T3 & T4)
C cells
thyroid gland secretes
TG
- storage form of TH
- Calcitonin by C cells
Parathyroid cells
Chief cells-Produce PTH
Oxyphill cells
Blood types
A
B
AB
O
Type A
Antigens present-A
Antibodies Prod-B
Can donate to-A, AB
Cn receive from-O, A
Parasympathetic fibers ( Craniosacral)
myelinated pre ganglionic (Long) (intramural)
Unmyelinated post (Short)
ACh to excite post
Release ACh
sympathetic fibers ( Thoracolumbar)
myelinated pre ganglionic (short) Unmyelinated post (long) ACh to excite post releases NE-most post ganglionic E- From adrenal gland ACh- sweat gland
Pituitary
also called hypophysis release 9 hormones -all peptides -all bind to (Extracellular receptors) -Regulate by neg. feedback
