Sensory or Afferent Nerves
Carries impuleses or messages from the sense organs to the brian, where sensations of touch, cold, heat, sight, hearing , taste, smell, pain, and pressure are experienced.
Motor - Efferent
Which carry impulses from the brain to the muscles. The transmitted impulses produce movement.
Is an automatic nerve reaction to a stimulus that involves movement of an impulse from a sensory receptor along the afferent nerve to the spinal cord, and a reponsive impulse along an efferent neuron to a muscle, causing a reation.
Is an exceptionally well-organized system that is responsible for coordinating all the many activities that are performed by the body. There are over 100 billion nerve cells, know as neurons, in the body.
Central Nervous System
What does the spinal cord and brain make up? Also, is the primary control for the whole nervous system.
Controls the involuntary muscles, such as the glands, blood, vessels, and heart. (outter part of the body to the CNS)
(Internal) Causes the internal regulations of impulses from the CNS to smooth muscle such as heart, blood vessels and glands.
1. Opthalmic. 2. Mandibular. 3. Maxillary.
Name the three branches of the trifacial or trigeminal nerve.
Affects the muscles of the temple, side of the forehead, eyebrow, eyelid, and upper part of the cheek.
Is a sensory-motor nerve that, with its branches, supplies the thumb side for the arm and back of the hand.
Is a smaller sensory-motor nerve than the ulnar and radial nerves; which its branches, its supplies the arm and hand.
is a senory-motor nerve that, with its branches, affects the little-finger side of the arm and palm of the hand.
stimulates or speeds up activity adn prepares the body for stressful situations.
operates under normal nonstressful conditions and helps restore and slow down activity, thus keeping the balance in the body.
Makes up the bulk of the brain. It is the cerebral cortex, in the part of the cerebrum from which most messages from the brain are sent - such as those conveying thought, hearing and sight.
Is located in the uppermost part of the midbrain had has two main parts: Thalamus and hypothalamus.
Located in the upper part of the diencephalon, acts as a relay station for sensory impulses and play a role in the recognition of pain and temperature in teh body.
Located in the lower part of the diencephalon, controls many bodily functions such as body temperature; it also controls the pituitary gland.
