Exam 2 - Endocrine System - Specific Glands Flashcards
Master control system of endocrine system
Hypothalamus
the pituitary gland is also called the
neurohypophysis
pituitary gland’s two lobes
anterior (adenohypophysis) and posterior (neurohypophysis)
the thyroid is made of structures called _____ that surround the _____
thyroid follicles; follicle lumen
this fluid stores hormones in the thyroid and is housed in the follicular lumen
colloid
these thyroid cells secrete calcitonin
Parafollicular cells (c cells)
three steps to the first phase of TH production
- Follicular cells secrete thyroglobulin into follicle lumen
- Iodide (I-) goes into follicular cell and becomes iodine
- Combine powers to become iodinated thyroglobulin - can be stored
three steps to second step of TH production
- Follicular cells absorb iodinated thyroglobulin
- Lysosomes hydrolyze thyroglobulin (break down using water)
- Makes t3 and t4, gets secreted into bloodstream
series of four glands on the posterior side of the thyroid
parathyroid
these glands are attached to the superior part of the kidney
Adrenal glands/superenal
the adrenal glands are composed of an outer ____ and an inner ___
adrenal cortex; medulla
this gland synthesizes over 25 steroid hormones
adrenal cortex
the adrenal medulla gets stimulated by
nervous system
adrenal medulla secrete hormones that have to do with __
fight or flight
this gland controls levels of glucose in the blood and helps with digestion
pancreas
