Q

How is the endocrine system regulated?

A

By feedback
E.g. a signal sent from the hypothalamus to the pituitary gland in the form of a ‘releasing hormone’ which causes the pituitary gland to releases ‘stimulating hormone’ into the bloodstream the hormone then signals the target gland (e.g. the adrenal glands) to secrete it’s hormone.

Q

What causes a dysfunction of bodily systems?

A

when too much or too little of an hormone is released at the wrong time.

Q

What are the two main parts of the pituitary gland?

A

the anterior pituitary (front)
the posterior pituitary (back)

17
Q

Give an example of a hormones that are released by the anterior pituitary + what they’re responsible for.

A

ACTH as a response to stress - stimulates the adrenal glands to produce cortisol.
Luteinising hormone (LH) + Follicle - stimulating hormone (FSH) - both important in the control of reproductive functioning + sexual characteristics.

18
Q

Give an example of a hormones that are released by the posterior pituitary + what they’re responsible for.

A

Oxytocin - stimulates contraction of the uterus during childbirth + is important for mother - infant bonding.

19
Q

how many adrenal glands are there + where are the adrenal glands located?

A

2
sit on top of the kidneys

20
Q

What are the two distinct parts that the adrenal glands are made up of?

A

The adrenal cortex
The adrenal medulla

21
Q

What are the main distinctions between the adrenal cortex and the adrenal medulla?

A

The hormones produced by the adrenal cortex are necessary for life + the hormones produced by the adrenal medulla aren’t.

22
Q

Give an example of a hormones that are released by the adrenal cortex + what they’re responsible for.

A

Aldosterone - responsible for maintaining blood volume + blood pressure

23
Q

Give an example of a hormones that are released by the adrenal medulla + what they’re responsible for.

A

Adrenaline + noradrenaline - hormones that prepare the body for fight or flight
Adrenaline helps the body respond to a stressful situation e.g. increasing the heart rate + blood flow to the muscles and brain.
Noradrenaline constricts the blood vessels causing blood pressure to increase.

24
Q

What are the ovaries responsible for?

A

The production of eggs

25
Q

What hormones do the ovaries produce?

A

Oestrogen
Progesterone

26
Q

What hormones do the testes produce?

A

Testosterone
