Fibrous connective tissue and Supportive connective tissue Loose fibrous tissue: supports epithelium and internal organs Dense fibrous tissue: tendons, ligaments Adipose tissue: specialized loose: store fat/protection/ insulation Hyaline cartilage: end of long bones, nose, ribs etc… Bone: compact, spongy

Fluid connective tissue: Blood platelets red blood cell plasma (surrounds formed elements) White blood cells

• • • Skeletal Smooth Cardiac

Skeletal muscle • has striated cells with multiple nuclei. • occurs in muscles attached to skeleton. • functions in voluntary movement of body. Smooth muscle • has spindle-shaped cells, each with a single nucleus. • cells have no striations. • functions In movement of substances in lumens of body. • is involuntary. • is found in blood vessel walls and walls of the digestive tract. Cardiac muscle • has branching, striated cells, each with a single nucleus. • occurs in the wall of the heart. • functions in the pumping of blood. • is involuntary.
