26
Q

Cells that respond to specific hormones

A

Target cells

27
Q

Hormone aka

A

Chemical messenger

28
Q

Small molecules derived from amino acids that have different side groups than the amino acid compromising proteins

A

Amino acid hormones

29
Q

Hormone made by tryptophan that regulates sleep-wake cycles

Aka pineal hormone

A

Melatonin

30
Q

Subdivisions of amino acid hormones

A

Tryptophan and amino acid tyrosine

31
Q

Catecholamines epinephrine norepinephrine and dopamine (neurotransmitters but also can be hormones)

A

Tyrosine

32
Q

This makes people sleepy when you eat turkey or drink warm milk before going sleeping for better sleep

A

Tryptophan

33
Q

Small chains of amino acids or small proteins that usually bear carbohydrate residues making then __

A

Peptide hormones

Glycoproteins

34
Q

Erythropoietin (kidneys) and inhibin (reprod.

A

Glycoproteins

35
Q

Membrane lipid, prostaglandin in this group of lipid derivatives

A

Arachnoid acid

36
Q

Derived from cholesterol

Ex sex hormones calcitriol corticosteroids (cortisol and aldosterone)

A

Steroid hormones

37
Q

Active vitamin D3

It’s from

A

Calcitriol

Kidneys

38
Q

Cortisol and aldosterone are from

A

Adrenal gland

39
Q

Why do hormone do to their targets?

A

Regulate movement of substances in and out of cells

40
Q

Are amino acid derivatives, peptides, and small proteins so liable in lipid bilayer of plasma membrane

A

No

41
Q

Series of intracellular molecules activated by hormone receptor bindings, act as second messengers

A

cAMP

42
Q

Release of calcium ions

A

cAMP

Cyclic AMP

43
Q

Hormone receptor binding leads to the activation of a membrane lipid enzyme which results in the formation of

A

Protein kinase C

44
Q

This alters activity of specific enzymes and channels or it binds to the intracellular regulatory proteins (calmodulin)

A

Calcium

45
Q

After calcium bonds to calmodulin, what happens

A

Emzes activate that amplify the cellular response

46
Q

Posterior of pituitary gland

A

Neurohypophysis

47
Q

Neurohypophysis releases 2 hormones

A

ADH and oxytocin OT

48
Q

Regulates urine volume and blood pressure

A

ADH

49
Q

Labor, milk let down reflex, uterine contractions,

A

Oxytocin

50
Q

Deficiency of ADH causes

A

Diabetes inspidus (overflow + tasteless)

51
Q

Swellings that are expanded acon endings of hypothalamic neurons coming from either the supra optic nucleus or para ventricular and has granules of ADH and OT

A

Herring bodies

52
Q

Narrow bridge of tissue connecting lobes of thyroid gland

A

Isthmus

53
Q
