Lab 1 Flashcards
Adrenal Cortext
Stimulates ACTH to secrete glucocorticoids
Testes
Tubules produce sperm
Testosterone and other steroids
FSH needed for regulate sperm production
Ovaries
Egg surrounding cells ( theca)
Makes androstenedione, corpus luteum secretes progesterone after ovulation
Has FH and LSH for egg production
Pancreas
Has alpha beta and delta cells
Alpha- when blood glucose is falling
Raises glucose blood levels
Insulin B cells- raises glucose blood levels, not enough = diabetes
Somatostatin secreted Delta cells = inhibits secretion of insulin
Parathyroid
Secrete PTH and increase ca+2 levels
Pineal gland
After age 7 it undergoes 75%
Synthesizes melatonin
Seasonal affective disorder
Thymus
It’s in endocrine, lymphatic, immune system
Maturation of T cells
Secretes thymopoitetin, thymosin, thymulin
Thyroid
Largest thyroid gland
Has TSH
Secretes thyroxine T4 and T3
Also has C cells , secretes calcitonin to regulate calcium balance
Pituitary gland
Has anterior adenohypophysis and neurohypophysis (posterior)
Hypophyseal portal system
These 6 hormones travels from hypothalamus to anterior pituitary an
Hypothalamic hormones
OT and ADH
Released by posterior pituitary
LH
For woman and men its the production of sperm
For men specifically- testosterone
FSH
For woman and men-Sex hormones
Woman- ovarian follicles make the sperm production
ACTH
Releases cortisol and stimulates the hormone for the cortex
PRL
AFTER BIRTH produce milk
Thyroid gland
Produces t4 and t3
Increases metabolic rate
Calcitonin
Bone development
Pancreatic islet
Glucagon- produces A of alpha cells
Produce each meal when Blood glucose is falling
Insulin secreted by B or beta cells
Secreted after each meal when blood glucose levels are high, amino acid and glucose uptake and not enough can cause diabetes mellitus
