What's the difference between odontophore and projection?
Odontophore
Definition:
(n.) A special structure found in the mouth of most mollusks, except bivalves. It consists of several muscles and a cartilage which supports a chitinous radula, or lingual ribbon, armed with teeth. Also applied to the radula alone. See Radula.
Example Sentences:
(1) The odontophoral cells are variable in size; they contain glycogen-filled "cores" as well as bundles of peripherally located filaments resembling myofilaments; and they are innervated like muscle cells.
(2) The odontophore and connective tissue-filled portion of the radular sac (called the "collostyle") of the slug, Limax maximus, were examined by light and electron microscopy.
(3) The parenchyma of the odontophore consists of modified muscle cells which are organized into irregular groups by incomplete trabeculae composed of conventional muscle cells.
(4) The extracellular matrix of the odontophore is very sparse and contains glycogen and fibrillar material but no histochemically demonstrable acidic mucosubstances.

(8) The roughly U-shaped odontophore possesses a thin capsule composed of connective tissue.
(9) Mineralization occurred more rapidly in Eusycon odontophore cartilage which has a significantly higher content of phosphatidyl serine than in Limulus gill or Loligo head cartilages.
Projection
Definition:
(n.) The act of throwing or shooting forward.
(n.) A jutting out; also, a part jutting out, as of a building; an extension beyond something else.
(n.) The act of scheming or planning; also, that which is planned; contrivance; design; plan.
(n.) The representation of something; delineation; plan; especially, the representation of any object on a perspective plane, or such a delineation as would result were the chief points of the object thrown forward upon the plane, each in the direction of a line drawn through it from a given point of sight, or central point; as, the projection of a sphere. The several kinds of projection differ according to the assumed point of sight and plane of projection in each.
(n.) Any method of representing the surface of the earth upon a plane.
