Q

What is the souce, target structure or cells and the function of Epinephrine

A

Source: Adrenal Glands

Target Structure: most cells

Function: ‘Fight or flight’

17
Q

What is the souce, target structure or cells and the function of Aldosterone

A

Source: Adrenal Glands

Target Structure: Kidney

Function: ↑ sodium ion reabsorbtion

also increases blood pressure.

18
Q

How does negative feedback help maintian homeostasis?

A

↑ amounts of substance needed = ↓ produced, which means homeostasis is maintained.

19
Q

What is the difference between hyper and hypo?

A

hypo - too little
hyper - too much

20
Q

How do the endocrine and nervous control systems work together during a stress response

A

The nervous system triggers the “fight or flight” response by releasing adrenaline (Epinephrine), while the endocrine system releases cortisol to sustain the stress response and regulate metabolism.

Epinephrine is both a hormone and a neurotransmitter

Do not need to memorize jsut know its existance

21
Q

How do the hypothalamus and pituitary work together?

A

Through the use of hormones and nerve impulses that stiumulate hormone secretion.

22
Q

Whats faster, nervous or endocrine?

A

Nervous.

23
Q

Diabetes Mellitus is also known as what. What does it do?

A

Type 1 diabetes (cannot produce insulin)

Mellitus = meal

24
Q

What is Diabetes Insipidus?

A

Too little ADH

Insipidus = ‘sip’-ing water because youre always dehydrated

25
Q

What is Addison’s Disease?

A

Hypo secretion of Aldostrone and cortisol.
