Chapter 5: Tissues

Adipose Tissue

(Fat) An organic molecule that includes glycerol and fatty acids. It lies between muscles and around organs/ joints that can serve as a cushion, insulation, or store energy in fat molecules.

Basement Membrane

Layer of nonliving material that anchors epithelial tissue to underlying connective tissue; barrier. Oxygen and nutrients diffuse into epithelial tissues from the basement membrane sides.

Cilia

Microscopic, hairlike extensions on the exposed surface of certain epithelial cells.

Collagen

The main structural protein found in skin and other connective tissues

Connective Tissue

Basic tissue type that consists of cells within an extracellular matrix, including bone, cartilage, blood, and loose and dense connective tissues. These support the body, bind together body parts, hold organs in place, and are the most abundant primary tissue in the body.

Elastic Fibers

Stretchy, yellow connective tissue fiber consisting of the protein elastin

Epithelial Tissue

One of the basic types of tissue; it covers all free body surfaces (Exposed to the outside or exposed internally to an open space). Varieties are classified by cell shape (squamous, cuboidal, or columnar) and number of layers (simple, stratified, or pseudostratified). They provide protection, absorption and filtration of materials through a membrane, secretion of substances, and line all body cavities.

Gland

An organ in the human or animal body which secretes particular chemical substances for use in the body or for discharge into the surroundings.

Goblet Cell

Epithelial cell specialized to secrete mucus

Intercalated Disc

Connection between cardiac muscle cells

Macrophage

Large phagocytic cell

Mucus

Fluid secretion of the mucous cells

Muscle Tissue

Contractile tissue consisting of filaments of actin and myosin, which slide past each other, shortening cells.

Nervous Tissue

Neurons and neuroglia composing the brain, the spinal cord, nerves, and sense organs. These control all body functions and the communication system.

Osteocyte

Mature bone cell

Tissue

Associate, assemble, and interact to form organs that have specialized functions within the body; epithelial, msucle, connective, and nervous.
