Question | Answer |
well organized system that is responsible for coordinating all the many activities that are performed both inside and outside of the body, | Nervous System |
the scientific study of the structure, function, and pathology of the nervous system | Neurology |
consists of the brain, spinal cord, spinal nerves, and cranial nerves and controls consciousness and voluntary functions | Central Nervous System |
system of nerves that connects the outer parts of the body to the central nervous system; carries impulses to and from the CNS | Peripheral Nervous System |
regulates the involuntary actions such as the actions of the smooth muscles, glands, blood vessels and heart | Autonomic Nervous System |
largest, most complex nerve tissue in body; controls sensation, muscles, glands, thinking, sensing, and feeling | brain |
portion of CNS that orginates in brain and extends down to lower trunk region; consists of 31 pairs of spinal nerves connecting to muscles, glands, and skin | spinal cord |
nerve cell; primary stuctural unit of the nervous system | neuron |
tree-like branchings of neuron the rceive impulses from other neurons | dendrites |
portion of neuron that sends impulses away from cell body to other neurons, glands, or muscles | axon |
whitish cords made up of bundles of nerve fibers (dendrites & axons) held together by connective tissue through which impulses are transmitted. | nerves |
carry impulses from the sense organs to the brain | sensory (afferent) nerves |
carry impulses from the brain tot he muscles to produce movement | Motor (efferent) nerves |
largest sensory nerve in face & serves as a motor nerve of the muscles that control chewing | fifth cranial nerve |
largest motor nerve of face; supplies and controls the muscles of facial expression | 7th cranial nerve |
supplies the fingers with impulses from environment or brain | digital nerve |
supplies the thumb side of the arm and the back of the hand with impulses from environment or brain | radial nerve |
supplies the little finger side of the arm and palm of the hand with impulses from environment or brain | ulnar nerve |
supplies the arm and hand with impulses from environment or brain | median nerve |
supplies the muscles of the calf, the skin of the leg, and the sole, heel, and underside of the toes with impulses from environment or brain | tibial nerve |
supplies muscles in front of leg, skin, top of foot, and toes with impulses from environment or brain | common peroneal nerve |
division of the common peroneal, extends deep behind muscles | deep peroneal nerve (anterior tibial nerve) |
division of the common peroneal, lies superficial, extends just underneath the skin | superficial peroneal nerve (musculocutaneous nerve) |
