        | Term 
 | Definition 
 
        | glia that wrap their flat extensions tightly around the nerve fibers, producing fatty insulating coverings called myelin sheaths. |  | 
        |  | 
        
        | Term 
 | Definition 
 
        | a division of the autonomous nervous system; also referred to as the craniosacral division. |  | 
        |  | 
        
        | Term 
 | 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 
 | 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 
 | 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 
 | Definition 
 
        | peripheral nerve ending specialized for response to particular types of stimuli; molecule that binds specifically with other molecules (hormones and neurotransmitters) |  | 
        |  | 
        
        | Term 
 | Definition 
 
        | automatic reactions to stimuli |  | 
        |  | 
        
        | Term 
 | 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. |  |

        | form the myelin sheaths around nerve fibers that are found in the PNS. |  | 
        |  | 
        
        | Term 
 | Definition 
 
        | gathered information from changes to the body caused by stimuli |  |

        | Term 
 | Definition 
 
        | division of the peripheral nervous system ;also called the voluntary nervous system. |  | 
        |  | 
        
        | Term 
 | Definition 
 
        | the region of communication between neurons |  | 
        |  | 
        
        | Term 
 | 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. |  |
