HNA&P Types of Tissues

Epithelial Tissue

The most common type of tissue is a layer of cells that form a barrier with specific properties. This tissue covers every exposed body surface; lines the digestive, respiratory, reproductive, and urinary tracts; surrounds internal cavities; lines the inner surfaces of the blood vessels and heart.

Connective Tissue

Diverse in appearance. All forms contain cells surrounded by extracellular matrix, consisting of protein fibers and a liquid known as the ground substance. The amount and consistency of the substance depends on the particular type of tissue.

Muscle Tissue

Individual cells in this tissue class have the ability to contract forcefully. Major functions include skeletal movement, soft tissue support, maintenance of blood flow, movement of materials along internal passageways, and the stabilization of normal body temperature.

Neural Tissue

Specialized to carry information or instructions within the body. The two basic types of cells present are nerve cells (neurons) and neuroglia (supporting cells). These cells are present in two locations within the body, the central nervous system (brain and spinal cord) and the peripheral nervous system (nerves connecting CNS with other tissues and organs).
