1
Q
hypothalmas
A
-is not a glad, but is one of the primary control centers of the brain and the main link between the endocrine and nervous system
2
Q
pituitary glad
- the “master glad”
- controls/regulates the other glands
A
-split into the anterior and posterior pituitary
3
Q
anterior pituitary
A
- Adrenocortioctropic hormone, stimulates the release of steroidal hormones by the adrenal cortex
- Follicle-stimulating hormone, development of ovum and sperm
- Growth hormone, stimulates cell growth
- Luteinizing hormone, stimulates release of of hormones from ovaries or testes
- Prolactin, stimulates milk production
- Thyroid stimulating hormone, stimulates thyroid
4
Q
Posterior pituitary
A
- Antidiuretic hormone, stimulates increased reabsorption of water by the kidney
- Oxytocin, stimulates uterine contractions and milk release
5
Q
Thyroid Gland
A
-secretes thyroxine when the base metabolic rate decreases
- secrets calcitonin, into the blood stream when calcium levels are high.
- helps bones absorb calcium and the kidneys to remove excess
6
Q
Para Thyroid Gland
A
-Parathyroid hormone (PTH), acts as a calcitonin antagonist preventing the kidneys from excriting calcium when the bodies calcium levels are low
7
Q
Adrenal Glands
A
- outer the adrenal cortex
- inner adrenal medulla
8
Q
adrenal cortex
A
- Cortisol, stimulates release of amino acids, lipids and glucose
- Aldosterone, increase in renal absorption of sodium and water (net increase in blood volume)
- Estrogen, development of secondary sexual traits
- Progresterone, uterine changes
- testosterone, secondary sex traits
9
Q
adrenal medulla
A
- Epinephrine, stimulates cardiac activity, vasoconstriction, glycogenolysis (increased BGL)
- Norepinephrine, vasoconstriction
10
Q
Pancreas
-digestive gland made up of head, body and tail
A
- both endocrine and exocrine
- exocrine side secretes digestive enzyme into duodenum
- endocrine side islets of langerhans
11
Q
islets of langerhan (act like an organ within an organ)
A
- main hormones
- glucagon from Alpha cells
- insulin from the Beta cells
12
Q
Gonads
A
- estrogen, sex traits
- progesterone, uterine changes
- testosterone, sex traits
13
Q
immune system
A
- the bodys response to infection
- detects antigens (proteins on viruses or bacteria)
- responds to kill invading agent
- leukocytes; White blood cells are the primary response
14
Q
cell mediated immunity
- derived from leukocytes called T-lymphocytes
- T-cells originate from thymus
- fight infections, t-cells move to infection site and attack the infection
A
Hv moral immunity
- from B lymphocytes, form antibodies
- the antibodies attach to invading antigens and are then removed by scavenger cells
15
Q
5 classes of antibodies
A
- IgM; instant response
- IgG; memory and recognizes repeat invasions
- IgA; in mucus membranes
- IgE; contributes to allergic reaction
- IgD; lowest concentration
