Nervous System Revision Sheet

1. 📌 Essentials

  • Neurons are the fundamental units, comprising soma, dendrites, axon, and synapses.
  • The CNS includes the brain (cerebrum, cerebellum, brainstem) and spinal cord.
  • The PNS consists of cranial nerves (12 pairs) and spinal nerves (31 pairs).
  • Major brain regions cerebral cortex (motor, sensory, association), diencephalon, brainstem cerebellum.
  • Spinal cord gray matter: dorsal horn (sensory), ventral horn (motor), lateral horn (autonomic).
  • Ascending pathways (sensory): dorsal columns, spinothalamic tract.
  • Descending pathways (motor): corticospinal tract.
  • Cranial nerves I-XII have specific sensory, motor, or mixed functions.
  • Reflexes involve sensory receptor → afferent neuron → CNS → efferent neuron → effector.
  • Typical neuron resting potential: ~ -70 mV; threshold: ~ -55 mV.
  • Blood supply: carotid and vertebral arteries.
