    Study Notes

    Nervous System Functions

    • Detects changes in the environment (sensory).
    • Processes information and makes decisions (integration).
    • Tells the body what to do in response (motor).

    Nervous System Systems

    • Central Nervous System (CNS)
      • Brain
      • Spinal Cord
    • Peripheral Nervous System (PNS)
      • Cranial nerves and branches
      • Spinal nerves and branches
      • Ganglia (clusters of neuron bodies)
      • Sensory receptors
      • Enteric nervous system

    Functional Organization

    • Somatic Nervous System
      • Sensory receptors detect changes in the external environment.
      • Sends sensory information to the CNS.
      • CNS makes decisions and sends motor signals to the muscles.
    • Autonomic Nervous System
      • Sensory receptors detect changes in the internal environment (e.g., blood pressure, glucose levels).
      • Sends sensory information to the CNS.
      • CNS makes decisions and sends motor signals to the organs and glands.
    • Enteric Nervous System (ENS)
      • Sensory receptors detect changes in the gastrointestinal tract.
      • ENS sends motor signals to the smooth muscle to control digestion.
      • CNS can override ENS decisions.

    Neuron Structure

    • Dendrites: Receive electrical signals.
    • Cell Body: Contains the nucleus and other organelles.
    • Axon: Sends electrical signals away from the cell body.
    • Myelin Sheath: Fatty tissue that surrounds axons; increases the speed of electrical impulses.

    Non-Nervous Cells in CNS

    • Astrocytes: Star-shaped cells that regulate the chemical environment around neurons and remove waste.
    • Oligodendrocytes: Create myelin sheaths in the CNS.
    • Microglial Cells: Destroy viruses and bacteria.
    • Ependymal Cells: Line specific cavities of the CNS.

    Non-Nervous Cells in PNS

    • Satellite Cells: Surround neuron cell bodies in ganglia; remove waste products.
    • Schwann Cells: Create myelin sheaths in the PNS.

    Multiple Sclerosis

    • Immune cells attack myelin sheaths, leading to a breakdown of nervous system functions.
    • No cure, only medication to slow the process.
