Composition of Blood
Blood is considered
CONNECTIVE TISSUE (cells
surrounded by a matrix).
The cells or FORMED
ELEMENTS in whole blood are:
The matrix is PLASMA, a

DORSAL ASPECT OF THE BRAIN:
1. The MENINGES are the three membranes that cover the brain and the spinal cord. The

How Stimulation Regulates Contraction:
The Muscle Twitch
Muscles can respond to a single stimulus with a single AP.
This is called a TWITCH.
Rapid contraction and relaxation occur because 2 processes
are occurring at the same time:
1) Calcium is being r
ELECTRONEUTRALITY = there is no excess of
charges on either side of the cell membrane.
However, the membrane is POLARIZED due to an
uneven distribution of charges:
The inner (cytosolic) portion of the membrane
behaves as if it were line
