Study Notes

Organization of the Nervous System

The Nervous System supplies the body wall and limbs (Somatic) and the Viscera (autonomic).

Types of Nerves

Vestibulocochlear nerve: sensory for balance and hearing
Glossopharyngeal nerve (IX): sensory for taste; motor fibers to the pharynx
Cranial nerves: 12 pairs
Spinal nerves: 31 pairs

Central Nervous System

Consists of the brain and spinal cord
Brain parts:
- Hemisphere: left and right halves of the brain
- Corpus callosum: connects the two halves of the brain, delivers messages between them
Brain lobes:
- Frontal: voluntary motor functions, planning, mood, smell, and social judgement
- Parietal: sensory reception and integration of sensory information
- Occipital: visual processing
- Temporal: hearing, smell, learning, memory, and emotional behavior

Functions of Nerves

Sympathetic and parasympathetic systems innervate many organs of the body, serving to balance functioning to maintain homeostasis

Neural Impulses

Afferent impulses (sensation): received from the body by the spinal nerves and sent to the cerebral cortex
Efferent impulses (movement): sent to the body by the spinal nerves and received from the cerebral cortex
