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
