overview of metabolism and hormones Flashcards
neuroendocrinology
the combined activity of tissues which regulate hormone release and control bodily function
hormones
a chemical substance secreted into the body fluids, with specific effects local or distant: target tissue through interaction with specific receptors
glands
secrete hormones into the blood
source of hormones
endocrine glands
nerve fibres
other tissues
classification of hormones peptides
derived from protein
soluble - faster acting
classification of hormones steroids
derived from lipids
insoluble - slower acting
adernal and pancreas release hormones that are ….
key regulators of exercise metabolism exercise and obesity/ diabetes
major functions related to exercise
alters enzymes activity P
alters member transport P
alter gene transcription and protein synthesis S
hormone receptor binding 1
hormone concentration in the blood
- hormone concentration goes up the target cells sees more of that hormone
hormone receptor binding 2
Blood flow to the tissue
hormone receptor binding 3
of target cell receptors
- systhesis - degradation
- gene expression
hormone receptor binding 4
sensitivity of receptors for the hormone
- upregulation
-down regulation
= delivery
{hormone} x blood flow
insulin Site of release and primary actions
pancreas (b cells)
increase glucose uptake
decrease lipolysis
glucagon Site of release and primary actions
pancreas (A cell)
increase liver glycogenolysis
epinephrine Site of release and primary actions
adrenal medulla
increase muscle glycogenolysis
norepinephrine site of release and primary actions
SNS fibres
adrenal medulla
increase lipolysis
