Flashcards in endocrine system: exam 4 (final) Deck (20):
1

where is the pituitary gland located?

it is 2 glands in one. attached to the hypothalamus by a stalk called the infundibulum

2

what is the anterior pituitary gland?

anterior pituitary (adenohypophysis) is made of secretory epithelium
blood flow to adenohypophysis travels from hypothalamus through hypophyseal portal system

3

what is the posterior pituitary gland?

(neurohypophysis) made of neural tissue connected to hypothalamus by nerve fibers hypothamalic-hypophseal tract

4

what gland sits on top of the kidney?

the adrenal gland

5

what is the structure of the kidney?

it is has 2 glands in one

6

what is the adrenal cortex?

it is part of the adrenal cortex is part of the adrenal gland made of secretory epithelium

7

what is the adrenal medulla?

part of the adrenal gland. inner part of adrenal gland made of neural tissue, cell bodies with no axons
gets input from preganglionic axons that exit spinal cord in ventral rami of spinal nerves t6-t11

8

what gland sits on the anterior of trachea just below larynx?

the thyroid gland

9

what is the structure of the thyroid gland?

has 2 thymic lobes connected by isthmus made of secretory epithelium

10

what are the 4 tiny glands that are located at the lateral edges of the thymic lobes and are made of secretory epithelium?

parathyroid glands

11

where are the pancreatic islets located?

in the pancreas make up 1 % of epithelial cells secrete hormones into the blood

12

pineal gland

see notes on brain

13

what is the location of the thymus gland?

superficial to heart medial to lungs

14

what are the gonads in males?

the testes- makes sperm and male hormones (testosterone)

15

what helps t-cells/ lymphocytes mature?

thymus gland

16

what are thymic lobes?

the thymus gland is split into 2 lobes held together by connective tissue has a capsule which is connective tissue around the lobes

17

what are projections from the capsule into thymus tissue?

trabeculae of thymus gland

18

what is the cortex of the thymus gland?

it is the outer layer of thymus tissue formed out of tightly packed lymphocytes

19

what is the deeper tissue of the thymus gland that contains epithelial cells that release hormones?

medulla of thymus gland

20

what are the gonads in females?

the ovaries- oval shaped glands on either side of uterus
