Hormones Flashcards
1
Q
hormone
A
signaling molecule transported to organs to affect physiology + behaviour
2
Q
steroid hormone process
A
- hormone enters cell
- binds to receptor in nucleus
- mRNA + protein synthesis
3
Q
protein hormones
A
- binds w receptor outside cell
- transduction pathway
- transcription factor in nucleus activated
- protein synthesis
4
Q
hormones diff to neurotransmitters
A
- larger spatial + temporal scale
- travel through circulatory system (not nervous system)
- slower
- not all or nothing
5
Q
neurohormones what are they
A
produced by endocrine that receive input from neurons
6
Q
hormone feedback control mechanisms
A
- other hormones
2 plasma concentration (ions, nutrients, binding globulin) - neurons + mental activity
- environment
7
Q
hormone effects on body
A
- growth
- reproductive cycle
- metabolism
- mood swings
- circadian rhythm
- hunger cravings
- immune system
8
Q
hpa axis
A
- hypothalamus released CORTH
- pituitary gland releases ACTH
- adrenal cortex releases cortisol
9
Q
hypothalamus hormones
A
- thyrotropin releasing hormone
- growth hormone
- gonadotropin
- corticotropin
10
Q
basic metabolic rate decrease (loop)
A
- hypothalamus releases thyreoliberin
- pituitary gland releases thyreotropin
- increased thyroid hormone release
- BMR increase
(negative feedback from 2-4)
10
Q
neurohormone production can be affected by
A
- other hormones by endocrine cells
- neurotransmitters
- pituitary gland hormones
- environment
11
Q
hypothalamus connected to which brain parts
A
- cortex
- reticular formation
- limbic system
12
Q
trophic hormones
A
target endocrine glands (regulation)
- stimulate cell no.
13
Q
compensatory hypertrophy
A
when tissue increases in size to fulfill activity of destroyed tissue
14
Q
hypothalamus main functions
A
- hunger
- mood
- body temp
- sex drive
- sleep
15
Q
posterior pituitary
A
- doesn’t have glands
- secrete vasopressin + oxytocin
