Study Notes

Anatomy and Physiology of the Nervous System

  • The spinal cord is a cylinder of nervous tissue about three feet long, encased by a vertical bone, and extends down the back from the base of the skull.
  • The central nervous system (CNS) includes the spinal cord, which has about 100 billion neurons and 30 trillion glia cells, and sits beneath the brain.
  • The brain has subdivisions stacked according to the degree of integration they provide, including the brainstem, cerebellum, diencephalon, and cerebrum.
  • The peripheral nervous system (PNS) transmits information and consists of sensory receptors, nerves, and two-way traffic.
  • The somatic division of the PNS is voluntary and receives signals from special and somatic receptors, conveying sensory signals to the brain and sending signals to skeletal muscles.
  • The autonomic division of the PNS is involuntary and operates automatically and unconsciously, conveying signals from the CNS to effect changes in smooth muscle, cardiac muscle, and glands.
  • All neural tissue within the body contains neurons, which are specialized for intercellular communication and supported by neuroglia cells.
  • Neurons have structural classifications including multipolar, unipolar, and bipolar neurons, with receptive regions, a biosynthetic center, and impulse-generating and conducting regions.
  • Functional classifications of neurons include sensory neurons, motor neurons, and interneurons, each with different roles in the nervous system.
  • There are three types of sensory receptors: exteroceptors for external and distance senses, proprioceptors for monitoring position and movement, and interoceptors for monitoring internal systems.
  • Neuroglia cells, which support and protect neurons, make up half the volume of the nervous system and include astrocytes, oligodendrocytes, microglia, and ependymal cells in the CNS.
  • The glial cells of the peripheral nervous system include satellite cells, which surround ganglia and regulate the environment around neurons, and Schwann cells, which form myelin sheath around peripheral axons.
