-oid, -oidal, -oidism, -odic

(Greek: a suffix; like, resembling, similar to, form)

A substance that is in a state between that of a solution and an emulsion, where particles are suspended in a fluid medium.

Collagens have great tensile strength, and provide these body structures with the bility to withstand forces that stretch them.

Collagens consist of three polypeptide chains arranged in a triple helix, and are bundled together in fibers. When boiled in water, collagen is converted into gelatin.

Collagen supplies the matrix in which the calcium salts that give the bones their hardness are deposited. Collagen is the substance of cartilage and tendon.

A substance capable of giving rise to a colloidal solution or suspension.
Very small, finely divided solids (particles that do not dissolve) that remain dispersed in a liquid for a long time due to their small size (usually less than 1 mm) and electrical charge. These particles have negligible settling velocity because their small mass have a low gravitational force compared to surface frictional forces.
1. Shaped like a cup; as, the cotyloid cavity, which receives the head of the thigh bone.
2. Pertaining to a cotyloid cavity; such as, the cotyloid ligament, or notch.
ctenoid (adjective), more ctenoid, most ctenoid
Descriptive of having many tiny projections on the edges like the teeth of a comb and as with many bony fish: Ctenoid scales vary in sizes, shapes, and structures ranging from strong and firm or soft and bending skins in fish.
cycloid (adjective), more cycloid, most cycloid
Resembling a circle.
Dog-like or similar to a dog; canine.
Similar in appearance to a tear.
Having the appearance of a finger.
deltoid (adjective), more deltoid, most deltoid
1. In the shape of the fourth letter of the Greek alphabet: A capitalized delta is a triangle; so, deltoid means triangular in shape or configuration.
2. The large muscle, roughly triangular in shape, that stretches from the clavicle (collarbone) to the humerus (the long bone in the upper arm) and so covers the shoulder: When a deltoid is contracted (flexed), it moves an arm away from the side of the body.

The central, strongest part of the deltoid muscle, raises an arm sideways while the front and back parts of the muscle can twist the arm.
