components of control system
sensor mechanism
integrator or control center
effector mechanism
feedback
afferent
signal traveling toward a particular center or point of reference
efferent
signal is moving away from a center or point of reference
Levels of control
intracellular ( regulates function w/in the cell
Intrinsic control (operate at tissue level
Extrinsic control ( outside control)
major elements

2 chemical bonds
Ionic (bond formed by transfer of 1 atom to another
Covalent ( 1 or more pairs of electrons between outer energy level of 2 atoms)
hydrogen bonds
for when ele tons are unequally shared
4 types of chemical reactions
synthesis reaction
