Q

Hypothalamic releasing and inhibiting hormones

what do they do and where are they released from?

A

hypothalamus

stimulates anterior pituitary hormones

2
Q

what do they do and where are they released from?

human growth hormone (hGH)

A

anterior pituitary

stimulates cell division, bone and muscle growth, metabolic functions

3
Q

thyroid-stimulating hormone (TSH)

what do they do and where are they released from?

A

stimulates the thyroid gland

anterior pituitary

4
Q

ACTH

what do they do and where are they released from?

A

stimulates the adrenal cortex to secrete glucocorticoids

anterior pituitary

5
Q

FSH

what do they do and where are they released from?

A

anterior pituitary

stimulates production of ova and sperm from overies and testes

6
Q

LH

what do they do and where are they released from?

A

stimulates sex hormone production from ovaries and testes

anterior pituitary

7
Q

Prolactin (PRL)

what do they do and where are they released from?

A

anterior pituitary

stimulates milk production from the mammary gland

8
Q

ADH (antidiuretic hormone)

what do they do and where are they released from?

A

posterior pituitary

promotes the retention of water by the kidneys

9
Q

oxytocin (OCT)

what do they do and where are they released from?

A

posterior pituitary

stimulates uterine muscle contractions and release of milk by mammary glands

10
Q

thyroxine (T4)

what do they do and where are they released from?

A

thyroid

increases metabolic rate and regulates growth and development

11
Q

calcitonin

what do they do and where are they released from?

A

thyroid
targets bones and kidneys to lower blood calcium by inhibiting release of calcium fro bone and reabsorption of calcium by kidneys (high calcium can lead to kidney stones, among other things)

12
Q
parathyroid hormone (PTH)
what do they do and where are they released from?
A

parathyroid
raises blood calcium levels by stimulating the bone cells to release calcium, the intestine to absorb calcium from food, and the kidneys to reabsorb calcium

13
Q

glucocorticoids

what do they do and where are they released from?

A

adrenal cortex
stimulates tissues to raise blood glucose and break down protein
an example is cortisol

14
Q

mineralcordicoids

what do they do and where are they released from?

A

adrenal cortex
example: aldosteron
promotes reabsorption of sodium and water by the kidneys

15
Q

gonadocorticoids

what do they do and where are they released from?

A

adrenal cortex

promotes secondary sexual characteristics

16
Q

epinephrine and norepinephrine

what do they do and where are they released from?

A

adrenal medulla

fight-or-flight hormones

17
Q

insulin

what do they do and where are they released from?

A

pancreas

lowers blood glucose and promotes the formation of glycogen in the liver

18
Q

glucagon

what do they do and where are they released from?

A

pancreas

raises blood glucose levels by converting glycogen in the liver to glucose

19
Q

estrogen

what do they do and where are they released from?

A

ovaries

stimulates uterine lining growth and promotes development of the female secondary sexual characteristics

20
Q

progesterone

what do they do and where are they released from?

A

ovaries

promotes growth of the uterine lining and prevents uterine muscle contractions

21
Q

testosterone

what do they do and where are they released from?

A

testes

promotes sperm formation and development of the male secondary sex characteristics

22
Q

what does the cerebellum do

A

Unconscious coordination of posture
Reflexes
Body movement and fine motor skills

23
Q

what does the medulla oblongata do

A

Reflexes

Involuntary bodily functions (heart rate, swallowing, breath rate, coughing)

24
Q

what does the pons do

A

Relay centre for right and left halves of brain

25
Q

what does the midbrain do

A

Processing info from sensory neurons in eyes, ear and nose

26
Q

what does the thalamus do

A

The great relay station- connective nerves across body

27
Q

what does the hypothalamus do

A

Helps regulate body’s internal environment and behaviour
Major link between endocrine and nervous system
Controls blood pressure, heart rate, body temp, basic drives, emotions

28
Q

what does the cerebrum do

A

Intellect, learning, memory, consciousness, language,

Processes and controls responses to sensory info
