    action potential  'wave' that moves along an axon in response to a stimulus. An action potential may be either afferent or efferent, depending on its source. wikipedia
    adrenaline rush a rush of energy that permeates the body when extreme danger is sensed. This response is mediated by the sympathetic division, and is antagonistic to the workings of the parasympathetic division. The actual 'rush' is caused by a release of epinephrine (adrenaline) and norepinephrine from the adrenal glands. wikipedia
    afferent  referring to an action potential that does not originate in the central nervous system, but instead originates in the sensory receptors of the peripheral nervous system. wikipedia
    anterior   to the front. Synonymous with ventral. wikipedia
    autonomic division  the nervous system division responsible for autonomous tasks like blinking, breathing, heartbeat and vascular control. It is not under conscious control, and therefore it cannot be controlled by thought. wikipedia
    Brain   the primary neurological center of the body. wikipedia
    Brainstem   the thin, tapering portion of the brain attached to the spinal cord, responsible for coordinating autonomic muscle movements, such as breathing, heart beat, walking, etc. wikipedia
    cerebrospinal fluid   the thick, cushy, nutrient dense fluid that surrounds vital neurological organs, including the brain. CSF provides the organs and cells of the central nervous system with nutrients, protects them from shock and trauma, lubricates the sides of the cranial cavity, and helps cool the organs of the CNS. wikipedia
    central nervous system  the control and integration sections of the nervous system, comprised of the brain and spinal cord. It receives stimuli from the peripheral nervous system, integrates and interprets those stimuli, and the sends the orders to execute an appropriate response to the stimulus wikipedia
    cephalization  the gradual expansion of the rostral portion of the central nervous system, including increases in the number of neurons and ganglia, and an increase in the blood flow to the associated areas. Cephalization is believed to increase intelligence in affected organisms, reaching it's pinnacle in the human brain. wikipedia
    contralateral  anatomical term referring to anything on the opposite side of the body, in relation to a midsagittal section. Antonym of ipsilateral. wikipedia
    cranial nerves   the 12 pairs of cranial nerves are nerves that link the various senses of the PNS to the brain, in the CNS. wikipedia
    effector  any organ, muscle or gland that performs an action upon reception of an action potential originating in the central nervous system. wikipedia
    efferent   refers to any action potential originating in the central nervous system that gives orders to an effector to perform an action in response to a stimulus. wikipedia
    ipsilateral  anatomical term referring to anything that is on the same side of the body, in relation to a midsagittal section. Antonym of contralateral.
    J wikipedia
    necrotic  dead wikipedia
    peripheral nervous system the portion of the nervous system responsible for the reception of stimuli, and the subsequent transfer of those stimuli to the central nervous system. wikipedia
    pons  the portion of the brain stem that attaches to the underside of the brain, thus allowing communication between the brain and the rest of the body. 'Pons' is Latin for 'bridge'. wikipedia
    rostral  rostral is an anatomical term referring to the front or foremost part of an organ or appendage. The word stems from Latin 'rostrum', or 'beak, nose'. Synonym to anterior. wikipedia
    somatic division  the nervous system division under conscious control. Most skeletal muscles are under conscious control. wikipedia
    spinal nerves  the 31 pairs of spinal nerves connect to the spinal cord on either side all along its length, sending information from many afferent sources to be interpreted in the brain. wikipedia
    stimulus  anything that elicits a response from an organism. wikipedia
    ventral  to the front. Synonymous with anterior. Typically used in veterinary medicine to refer to the underside of an animal.
