    Study Notes

    Nervous System I – Super 7 Organization

    • Central Nervous System (CNS) includes the brain and spinal cord, integrating sensory input and directing motor output.
    • Peripheral NS (PNS) includes nerves and ganglia outside the CNS, with sensory and motor divisions.
    • Neurons respond to stimuli by conducting impulses and are classified by structure and function.
    • Synapses transfer information between neurons, with chemical and electrical synapses.
    • Neuroglia support neurons in the CNS and PNS, each with specific functions.
    • Cerebrospinal Fluid (CSF) reduces brain weight by 97%, protects CNS, nourishes brain, and rids waste.
    • The brain's structures include the cerebrum, brain stem, diencephalon, epithalamus, and cerebellum.
    • The spinal cord is organized into ascending tracts (sensory) and descending tracts (motor).
    • Sensory receptors are classified by stimulus type and location, with nonencapsulated and encapsulated nerve endings.
    • The somatosensory system interprets input from exteroreceptors, interoreceptors, and proprioceptors at three levels.
    • The Autonomic Nervous System consists of the parasympathetic and sympathetic divisions, originating in the brain.
    • The parasympathetic and sympathetic divisions have distinct functions and are involved in regulating involuntary bodily functions.
