Term
Myelin
Definition
White, fatty, lipid substance
Term
Myelin Sheath
Definition
tight coil of wrapped membranes enclosing an axon.
Term
Neuron (Nerve Cell)
Definition
cells of the nervous system specialized to transmit messages out of the body
Term
Neurotransmitters
Definition
chemical released by neurons that may, upon binding to receptors of neurons or effector cells, stimulate or inhibit them.
Term
Occipital Lobe
Definition
the visual processing center of the mammalian brain containing most of the anatomical region of the visual cortex.
Term
Oligodendrocytes
Definition
glia that wrap their flat extensions tightly around the nerve fibers, producing fatty insulating coverings called myelin sheaths.
Term
Parasympathetic Division
Definition
a division of the autonomous nervous system; also referred to as the craniosacral division.
Term
Parietal Lobe
Definition
positioned above the occipital lobe and behind (posterior to) the frontal lobe and central sulcus. The parietal lobe integrates sensory information among various modalities, including spatial sense and navigation
Term
Peripheral Nervous System (PNS)
Definition
system of nerves that connects the outlying parts of the body with the central nervous system.
Term
Pineal Body
Definition
small endocrine gland in the vertebrate brain. It produces the serotonin derivative melatonin, a hormone that affects the modulation of sleep patterns in the circadian rhythms and seasonal functions.
Term
Pituitary Gland
Definition
the neuro-endocrine gland located beneath the brain that serves a variety of functions including regulation of the gonads, thyroid, adrenal cortex, water balance, and lactation.
Term
Receptors
Definition
peripheral nerve ending specialized for response to particular types of stimuli; molecule that binds specifically with other molecules (hormones and neurotransmitters)
Term
Reflexes
Definition
automatic reactions to stimuli
Term
Satellite Cells
Definition
line the exterior surface of neurons in the peripheral nervous system (PNS). Satellite glial cells also surround neuron cell bodies within ganglia.[1][2] They are of a similar embryological origin to Schwann cells of the PNS, as they are both derived from the neural crest of the embryo during development.
Term
Schwann Cells
Definition
form the myelin sheaths around nerve fibers that are found in the PNS.
Term
Sensory Input
Definition
gathered information from changes to the body caused by stimuli
Term
Somatic Nervous System
Definition
division of the peripheral nervous system ;also called the voluntary nervous system.
Term
Synapse
Definition
the region of communication between neurons
Term
Temporal Lobe
Definition
located beneath the lateral fissure on both cerebral hemispheres of the mammalian brain. The temporal lobes are involved in the retention of visual memories, processing sensory input, comprehending language, storing new memories, emotion, and deriving meaning.
Term
Thalamus
Definition
Mass of gray matter found in the diencephalon of the brain.
