To connect and support the other tissues of the body.

How are connective tissues classified?

Based on the type of cell or cells and based on the type of intercellular matter found between the cells.

What is areolar (loose) connective tissues?

Connective tissues with fibroblasts, microphages, and mast cells.

What are fibroblasts?

The principal type of cell that secretes proteins into the spaces between the cells.

What are macrophages?

Cells that engulf foreign agents

What are mast cells?

Cells that secrete histamines and other chemicals that cause inflammation

What is inflammation?

WHen the blood vessels dilate causing swelling, erythema, and pain in the area

What does erythema?

To turn red

What is edema?

Swelling

What two proteins are secreted by fibroblasts?

Collagen and elastic

What is collagen?

What is adipose tissue?

Fat tissue

What is the function of adipose tissue?

To store food for energy, to insulate against theater loss, and to support and protect the organs it encloses

What are three common locations of adipose tissue?

Under the skin, around the kidneys and eyeballs, and around the buttocks and breasts.

What are the two subtypes of dense fibrous connective tissue?

Regularly arranged dense fibrous connective tissue and irregularly arranged dense fibrous connective tissue.

What are five places where dense fibrous connective tissue is common?

Tendons, ligaments, dura mater, fascia, perichondrium, and periosteum

What does peri mean?

Around

How do regularly arranged dense fibrous connective tissue look?

The protein fibers are arranged in parallel bundles resulting in a flat and smooth shape

How do irregularly arranged dense fibrous connective tissue look?

The protein fibers are interwoven and running in all directions.

What is special about cartilage that makes it unlike any other connective tissue?

It contains no blood vessels

What are the three subtypes of cartilage?

Hyaline Cartilage, Fibrocartilage, and Elastic Cartilage

What are four locations where Hyaline Cartilage is found?

The long bones of the body, the front of the nose, the trachea and larynx, and the surfaces of the articulating bones

Where is fibrocartilage found?

The intervertebral disks

Where is elastic cartilage found?

The external ear (pinna)
