Their main function is to send electrical signals over short and long distances in the body, and they are electrically and chemically excitable. Hypoglossal nerve - motor fibers for tongue movements sensory impulses from tongue Neurons are the basic units of the brain.Accessory nerve - motor fibers to sternocleidomastoid & trapezius.are used as building blocks of structure, and artificial neurons as building. Functions: support, insulate, and protect neurons. Sensors - Download Adaptation Evolution Population Continuously Best. Vagus nerves - sensory and motor fibers for pharynx, larynx, and thoracic & abdominal viscera (mostly parasympathetic = promote digestion & regulate heart activity) Support cells in the CNS are grouped together as neuroglia (AKA glia or glial cells) nerve glue.Glossopharyngeal nerve - sensory for posterior taste buds motor fibers to the pharynx (swallowing & saliva production) carotid artery pressure sensors.Vestibulocochlear nerve - sensory for balance and hearing.An action potential occurs when neuronal dendrites receive enough excitatory postsynaptic potential (EPSPs) to open voltage-gated sodium channels, resulting in rapid depolarization of the neuronal. Facial nerve - sensory for anterior taste buds motor fibers for facial expression and lacrimal & salivary glands An action potential is defined as a brief change in the electrical potential across the membrane of a neuron that occurs in response to a stimulus.Peripheral nerves - epineurium, perineurium, endoneurium. Abducens nerve - motor fibers to eye muscles (lateral movement) Cerebellum - molecular, Purkinje, granular layers.Trigeminal nerve - sensory for the face, nose, & mouth motor fibers to chewing muscles.Trochlear nerve - motor fiber to eye muscle (superior oblique).Oculomotor nerve - motor fibers to eye muscles (most movements, lens shape, & pupil size).
