Q

Describe Dense Connective tissue

A

Main matrix element is collagen fibers
Cells are fibroblasts
Examples - tendon (attach muscle to bone) and ligaments (attach bone to bone)

Q

Describe, name function and location of Adipose connective tissue

A

Matrix is an areolar tissue where fat globules are
Many cells contain large lipid deposits
Functions- insulates, protects, and site of fuel storage
