Hormones: regulation of secretion

Question 1

What is the definition of humoral stimuli?

Answer 1

control of hormone release in response to change in extracellular fluid

Question 2

What is the definition of neural stimuli

Answer 2

nervous system secrets a hormone in endocrine gland

Question 3

What is the definition of hormonal stimuli

Answer 3

A release of a hormone in response to another hormone

Question 4

What happens in hormonal stimuli if Ca is too low

Answer 4

PTH hormones stimulates osteoclasts(bone cells) which increases Ca

Question 5

What happens in hormonal stimuli if Ca is too high

Answer 5

No PTH secretion (inhibition until Ca levels lower)

Question 6

Describe the steps in neural stimulation

Answer 6

1) Action potential travels along a neuron
2) Release neurotransmitter to endocrine cell
3) Endocrine cell secretes hormones into bloodstream
4) Hormone in blood travel to its target

Question 7

Describe hormonal stimulation of anterior pituitary

Answer 7

Hypothalamus release hormones to anterior pituitary
Anterior pituitary release hormones to target endocrine cell
Endocrine cell release hormones to target cells
