|
Nervous tissue |
Primary function of nervous tissue is to communication throughout the body Subdivided in two categories of cells; neurons - actually communicate neurogila- helps and support the neuron Nerons contain several distinct components : dendrites -receive signals coming from particular neurons cell body-largest portion of a neuron;contains the nucleus Axon-"output" component; sends information from neuron to another structure |
|
|
Cardiac muscle |
Fibers are branched in shape Also contains striation in the light microscope Is under involuntary control (meaning an individual does nor consciously control it's contractions ) Typically each cell has only one nucleus Is only found in the walls of the heart Contains special juniors called intercalated discs |
