Term

 

Epithelial

Tissue

Definition

always has an exposed surface and a bound surface (basement membranes), cells closely packed together


Location: lines body cavities and covers body surfaces

Term

 

Muscular

Tissue

Definition

cell are either (1) longer and cylndrical, (2) branched cylindrical, or (3) spindle (fusiform); cells are closely packed together


Location: (1) skeletal-found attached to bones

(2) cardiac-found only in the heart

(3) smooth (vesceral)- found in GI tract in the walls of blood cells

Term

 

Nervous

Tissue

Definition

functional cell of the nervous system is the neuron which is composed of an axon, dendrites, and a cell body; conducts electrical impulses-all other cells of the nervous system are call neurogila (support cells)


Location: brain, spinal cord, peripheral nerves

Term

 

Connective

Tissue

Definition

most varied type of tissue in the body; usually cells are seperated by intercellular "matrix"; matrix may contain collagen, elastic, and reticular fibers


Location: bone, cartilage, tendons, ligaments, blood, adipose tissue, loose connective tissue

Term

 

Collagen

Fibers

Definition
made of protein collagen; large strong protein fibers gives tissue tremendous strength
Term

 

Elastic

Fibers

Definition
made of protein elastic; thin stretchy fiber
Term

 

Reticular

Fiber

Definition
made of collagen; thin branched fiber that gives tissue its shape
