nerves coming from the CNS to the voluntary muscles, consisting of motor neurons. myelin fatty substances produced by certain glial cells that coat the axons of neurons to insulate, protect, and speed up the neural impulse. nerves bundles of axons coated in myelin that travel together through the body. nervous system an extensive network of specialized cells that carries information to and from all parts of the body. neuron the basic cell that makes up the nervous system and that receives and sends messages within that system. neuroscience a branch of the life sciences that deals with the structure and function of neurons, nerves, and nervous tissue, especially focusing on their relationship to behavior and learning. neurotransmitter chemical found in the synaptic vesicles that, when released, has an effect on the next cell. occipital lobe section of the brain located at the rear and bottom of each cerebral hemisphere containing the visual centers of the brain. olfactory bulbs two projections just under the front of the brain that receive information from the receptors in the nose located just below. ovaries the female gonads. pancreas endocrine gland that controls the levels of sugar in the blood. parasympathetic division part of the ANS that restores the body to normal functioning after arousal and is responsible for the day-to-day functioning of the organs and glands. parietal lobes sections of the brain located at the top and back of each cerebral hemisphere containing the centers for touch, taste, and temperature sensations.

peripheral nervous system (PNS) all nerves and neurons that are not contained in the brain and spinal cord but that run through the body itself. pineal gland endocrine gland located near the base of the cerebrum that secretes melatonin. pituitary gland gland located in the brain that secretes human growth hormone and influences all other hormone-secreting glands (also known as the master gland). pons the larger swelling above the medulla that connects the top of the brain to the bottom and that plays a part in sleep, dreaming, left–right body coordination, and arousal. positron emission tomography (PET) brain-imaging method in which a radioactive sugar is injected into the subject and a computer compiles a color-coded image of the activity of the brain with lighter colors indicating more activity. receptor sites holes in the surface of the dendrites or certain cells of the muscles and glands, which are shaped to fit only certain neurotransmitters.
