A SKELETON IS MANY THINGS: symbol of danger and death, a key that opens any door, a secret kept in a closet, the outline of a novel or grand plan . . . and the 200-odd bones that hold up each human body.

Amphibian: A member of a class of vertebrates that live on both land and in wate, such as a frog.
Arachnid: A member of a class of arthropods with four pairs of legs, such as a spider or a scorpion.
Arthropod: A member of the arthropoda division of the animal kingdom. They have a segmented exoskeleton with jointed legs. Arachnids, insects, crustacea, millipedes, and centipedes are all examples of arthropods.
Backbone: A strong, flexible chain of bones that runs the length of the body in humans and many other animals. It is aslo known as the spine or vertebral column.
Bone: A hard body of tissue that gives strength to the skeleton. In humans and many animals, it is composed of outer compact bone and inner spingy bone and bone marrow.
Canine Tooth: A pointed tooth, usually next to the incisors, that grops and pierces food.
Carnassial Tooth: A specialized tooth on a carivore that is adapted for tearing meat. Most carnassial teeth are large and long.
Cartilage: A touch, flexible substance that protects vertebrate joints. It is sometimes called gristle. Catilaginous fish, such as sharks, have a skeleton made entirely of cartilage.
Chitin: A light, strong substance found in the exoskeleton of arthropods
Collegen: A connective protien that forms strong, elastic fibers. It is found in bone and skin.
Compact Bone: The hard material that forms the outer layer of a bone.
Cranium: The part of the skull that surrounds the brain
Crustacean: A member of a class of maily aquatic arthropods, such as crabs or lobster, with a hard case, or "crust," that encloses the body.
Dentine: A hard substance beneath the enamel of the vertebrate teeth. It is also known as ivory.
Dislocate: A movement that pulls or pushes a bone out of its place within a joint.
Echinoderm: A marine invertebrate, such as starfish, with a skeleton made up of hard, bony plates cfalled ossicles.
Enamel: A touch substance that fourms the outer coating of vertebrate teeth.
Endoskeleton: A hard skeleton found inside an animal's body.
Exoskeleton: A hard skeleton outside of an aminal's body
Ominvore: An animal that eats both plant and other animal material.
Opposable: As opposable thumb (in humans) or big toes (in chimps and some other animals) is one that can be manipulated to touch, or oppose, the other fingers or toes on ths same hand or foot. This enables the limb to be used for holding and manipulating objects.
Orbit: A bony socket in which the eyeball is situated.
Ossicle: Any small bone or other calcified structure, such as a plate in an echinoderm shell or an exoskeleton. In humans, it is used to refer to small bones within the ear.
Ossification: The process whereby cartilage turns into hard bone. In humans, some ossification continues to cover after birth.
Periosteum: A thin, strong membrane that covers the surface of bones, except at the joints.
Phalanges: The bones of teh fingers or toes in vertebrates, including humans.
Premolar: Vertebrate toothe that is situated in front of the molars.
Pronotum: Protective head sheild in some insect exoskeletons.
Reptile: A member of a class of vertebrates with scaly skin that lays sealed eggs. Snakes, lizards, and crocodiles are all reptiles.
Rodent: A member of an order of mammals with continuously growing incisors that are kept the right size by continuously gnawing. rabbits and guinea pgs are both rodents.
