| Integument | covering |
| Interneuron | Type of neuron which connects one neuron to another; only in CNS |
| Iris | Controls how much light enters the eye |
| Keratin | protein found in epidermal cells; waterproofs |
| Lateral | toward the side |
| Malleus | Bone in middle ear; shaped like a hammer; touches tympanic membrane |
| Matrix | non-living substance secreted by fibroblasts; found in connective tissue |
| Medial | closer to the middle |
| Melanin | pigment found in epidermal cells; gives color to skin |
| Meninges | Membranes which cover and protect brain. |

| Neuroglia | Supportive cells of the nervous system. |
| Neuron | Nerve cell. |
| Neurotransmitter | Chemical that allows the passage of a nerve impulse from one neuron to another. |
| Optic | nerve that carries visual nerve impulses to brain |
| Pituitary | Master gland of the body |
| Proximal | closer to the point of attachment |
| Receptors | Specialized structures that detect changes in the environment. |
| Retina | layer in back of eye that contains rods and cones |
| Rods | Structures in eye specialized for black and white vision. |
| Sclera | White of the eye |
| Sebaceous | oil glands of the skin; associated with hair follicles |
| Semicircular | canals which function in balance and equilibrium |
| Sensory | Nerve which carries nerve impulse from receptors TO CNS. |
| Simple | epithelium with one layer |
| Smooth | involuntary muscle with spindle shaped cells |
| Spinal | nerves in the peripheral nervous system; involved in |
| Stratified | epithelium with more than one layer |
| Striated | skeletal muscle; appears striped |
| Superficial | near or on the surface |
| Superior | part is above another |
| Synapse | Gap that nerve impulse must "jump" across |
| Tendon | dense regular connective tissue; connects muscle to bone |
| Tissue | a group of the same kind of cell with a specific function |
| Transmission | Sending "messages" through the body |
| Cochlea | contains receptors for hearing |
| Ossicles | three small bones of middle ear; transfer sound waves from tympanic membrane to cochlea |
| Pineal | gland that controls our sleep-wake cycle |
| Pupil | opening in iris that allows light to reach lens |
