Tissues are any of the distinct types of material of which animals or plants are made, consisting of specialized cells and their products.

Connective, epithelia, muscle, nervous are the four types of tissue.

Connective tissue perform support and protection for the body.

Epithelia tissue provides protection, secretion, absorption, and filtration.

Muscle tissue provides movement, good posture, joint stabilization, and heat generation.

Nervous tissues conduct impulses.

Classifications of the four types.

Connective: connective tissue proper, dense connective, cartilage, and bone tissue.

Epithelia: squamous, cuboidal, and columnar are the three general cell shapes.

Muscle: skeletal, smooth, and cardiac.

Nervous: neurons, and the neuroglia.

Specializations of epithelia




Transitional epithelium

Where the four tissues are found

Connective- found in the cartilage and bone

Epithelial- found of the internal and external surfaces of the body

Muscle- found within the walls of the organs

Nervous- can be found in nerve cells which are located throughout the body
