Epithelial Tissues

Epithelial tissue

Connective tissue

Muscle tissue

Nervous tissue

•ON SURFACES of body or cavities - :. free surface that protects, absorbs, or secretes; Will sometimes see air/cavity above it when viewing on a slide.

•NOT DEEP (as in close to bone)! But attaches to connective tissue below at junction called basement membrane

•Most abundant and widespread type type of tissue

•Binds or connects - e.g., tendons & ligaments

•Supports or gives structural strength - e.g., bone & cartilage

•Provides energy - e.g., adipose tissue

•Has type specific cells (--cytes - e.g., adipocyte)

• •Cells embedded in extracellular matrix, like
• fruit in jello salad

•Matrix forms most of the tissue structure, rather than cells

Move, change shape of hollow structures (stomach), pull on bone for movement

control, regulate

Single layer or flattened cells with disc-shaped nuclei 

Lines blood vessels, lymph nodes, and the alveoli of the lungs

Single layer of cubelike cells

found on the surface of the ovary and the thyroid

Single layer of tall cells with oval nuclei

Lines the intestines

Superficial cells that are elongated and columnar

Found in the ducts

Basal cells that are cuboidal or columnar

Makes up the epidermis of the skin

Cells of different heights with nuclei at differnt levels

Form the lining of the respiratory tract

Simple Squamous Epithelium

STRATIFIED SQUAMOUS EPITHELIUM

SIMPLE COLUMNAR EPITHELIUM

Psuedostratified Ciliated columnar epithelium

SIMPLE CUBOIDAL EPITHELIUM
