  • Over one trillion neurons are present in the human body
  • Four main parts of a neuron: Cell body/Soma/Cyton, Dendrites, Axon, and Axon terminals
2

Types of Neurons and Nerves

  • Three types based on function: Sensory, Motor, and Association neurons
  • Sensory neurons carry impulses from sense organs to CNS
  • Motor neurons carry impulses from CNS to effector organs (muscles/glands)
3

Nerve Impulse Transmission

  • Nerve impulse is an electrical phenomenon traveling along the axon
  • Three stages: Polarization, Depolarization, and Repolarization
  • Polarization: Resting state with positive charge outside, negative inside
4

Central Nervous System - Brain

  • Brain weighs about 1.3 kg and is enclosed in cranium
  • Protected by three meninges: Dura mater, Arachnoid mater, Pia mater
  • Cerebrospinal fluid fills space between meninges for protection and nutrition
