info in a neuron
dendrite to cell body to axon
Primary tissues in the body
neurons, muscle cells, epithelial, connective tissue
neuroglial cells
support neurons 5:1 ratio
intercalated disks location and function
cardiac muscle, pumps out blood efficiently, needed for rhythm
what muscle is voluntary and involuntary
diaphragm, skeletal
epithelial tissue
classified by
forms membranes that cover the surfaces of the body and various glands
shape and number of layers
Total body water
everything minus GI tract and kidneys and lungs
intracellular fluid
inside cells
extracellular fluid
outside of cells, if drawn blood, will get extracellular fluid the most
blood plasma
in blood vessels, cells
interstitial fluid
fluid outside of blood vessels
the cell membrane is made mostly of what
lipids, nonpolar
4 major atoms
O C N H
Superoxide molecules
have a free radical, antioxidants help to get rid of the free radical
Why is glycogen stored in liver and skeletal muscle
liver, pumps out sugar in blood
skeletal muscle needs it for a source of energy
anabolic steroids
make more muscle
5 functions of proteins
regulation (control DNA Replication), structural/contractile (actin/myosin), catalytic (enzymes), immunological (antibodies), transporters/carriers
Lysosome
takes out worn out organells and breaks down or recycled
peroxisome
deals with oxygen reactions. Breaks down toxic things. oxidation reactions
Mitochondrian
makes energy
Ribosomes
makes proteins. Translation occurs here
Rough ER
has ribosomes on it
Smooth ER
steroid production, lipids and Ca+
Golgi Complex
packages and ships off molecules
