Nervous and endocrine system - ✔✔What are the two systems that provide overall control of body
function?



Central Nervous System, Peripheral Nervous System, and Autonomic Nervous System - ✔✔What are the
three subdivisions within the Nervous System?



Neurons - ✔✔The cells of the nervous system

Responsible for conduction nerve impulses within the brain as well as from one part of the body to
another



Action potential - ✔✔The nerve's threshold of stimulus



Synapse - ✔✔A junction between two neurons



Terminal button - ✔✔Bulge at the end of the nerve in the synapse



Central Nervous System - ✔✔The overall control center of the body

Consists of the brain and spinal chord



Cerebral Cortex - ✔✔Responsible for essential functions as thought, learning, memory, consciousness,
sensations such as pain or heat, and the initiation of muscle movement



The core of the brain - ✔✔Serves as a relay station between sensory inputs from the periphery of the
body to the cerebral cortex



Cerebellum - ✔✔Coordinating center for sensory (vision and hearing) and receptors and coordination



Brainstem - ✔✔Consists of the midbrain (blood pressure, heart rate, respiration and digestion), pons
(coordination of movement) and medulla oblongata

, Contains important control center the for ANS



Peripheral Nervous System - ✔✔Consists of the nerves that carry impulses away from the CNS to the
various parts of the body and those that carry impulses from the periphery back to the CNS

Sensory nerves- conduct messages back to the CNS front he receptors (Touch and pain)

Motor nerves- carry out a response formulated in the CNS to a muscle to initiate body movement



Cranial nerves and spinal nerves - ✔✔Two components to the peripheral nervous system



Olfactory nerve - ✔✔First cranial nerve that allows us to smell



Optic nerve - ✔✔Second cranial nerve and allows us to see



Auditory nerve - ✔✔Eighth cranial nerve that allows us to hear



Trigeminal nerve - ✔✔Fifth cranial nerve that supplies sensation to the teeth and jaws



Muscles of mastication - ✔✔The muscles responsible for jaw movement during chewing



Facial nerve - ✔✔Seventh cranial nerve which supplies motor fibers to the muscles of facial expression
and allows us to smile, frown, wrinkle our brow, etc



Trigeminal nerve's three divisions - ✔✔1. Ophthalmic- first division that goes to the eye and forehead

2. Maxillary- second division serves the maxilla

3. Mandibular- third division serves the mandible



Spinal nerves - ✔✔Second component to the PNS

Origin of spinal cord running through the vertebral column
