Study Notes

Tissues

Tissues are groups of similar cells that perform specific functions
Four primary tissue types: epithelial, connective, muscle, and nervous

Epithelial Tissue

Covers body surfaces, lines cavities, and forms glands.
Functions in protection, secretion, absorption, excretion, and filtration.
Characteristics include a close arrangement of cells, little extracellular material, and a high regenerative capacity.
Types include squamous, cuboidal, and columnar, as well as simple or stratified, and membranous or glandular.

Connective Tissue

Most diverse and abundant tissue type
Functions in support, connection, protection, transportation of substances, and defense against infection.
Composed of various cell types in a large extracellular matrix.
Matrix can contain protein fibers (collagen, reticular, and elastic), and ground substance.
Examples include fibrous, cartilage, bone, and blood.

Muscle Tissue

Responsible for most body movements.
Three types include: skeletal, cardiac, and smooth.
Skeletal muscle is attached to bones and responsible for voluntary movements.
Cardiac muscle forms the heart walls, and is responsible for involuntary contractions.
Smooth muscle is found in the walls of organs and blood vessels, and responsible for involuntary movements.

Nervous Tissue

Composed of neurons, nerve cells, specialized for communication, integration, and coordination of body functions. Also a composite tissue.
Includes components of the brain, spinal cord, and nerves.
Possesses limited capacity for regeneration.

Membranes

Membranes are thin sheets that cover body surfaces or line body cavities.
Four main types include: epithelial, mucous, serous, and synovial.

Epithelial Membranes

Cutaneous membranes (skin) are composed of epidermal and dermal layers.
Serous membranes line closed body cavities and secrete serous fluid, which reduces friction.
Mucous membranes line body openings that are exposed to the exterior.

Connective Tissue Membranes

Synovial membranes enclose small cavities that allow for friction-free movement.

Tissue Regeneration

Epithelial and connective tissues have a high capacity for regeneration.
Damage to these tissues results in healing that is rapid.
