Elastic cartilage, which is a form of connective tissue, is one of three types of cartilage found in the human body. It is also recognized by its ability to snap back into an original form – or resting form – due to the addition of elastin fibers to the extracellular matrix. It is located in the pinna of the ear, external and internal auditory tubes, epiglottis, and larynx.

The primary osseous tissue function is to form bones that allow the body to move by providing attachment sites for muscles and tendons. It also provides support for internal structures, protects organs and tissues from damage, and serves as a site of mineral storage. The bone is made up of compact bone, spongy bone, and bone marrow. Compact bone makes up the outer layer of the bone. Spongy bone is found mostly at the ends of bones and contains red marrow. Bone marrow is found in the center of most bones and has many blood vessels.

Adipose tissue, also known as fat tissue or fatty tissue, is a connective tissue that is mainly composed of fat cells called adipocytes. Adipocytes are energy storing cells that contain large globules of fat known as lipid droplets surrounded by a structural network of fibers. It is found all over the body. It can be found under the skin (subcutaneous fat), packed around internal organs (visceral fat), between muscles, within bone marrow and in breast tissue.
