Topics in Neural Control and Coordination

1

Coordination and Neural System Overview

  • Coordination is the process through which two or more organs interact and complement each other's functions
  • Example: During physical exercise, muscles need more oxygen, so heart rate increases, breathing rate increases, and blood flow increases
  • Neural system and endocrine system jointly coordinate all body activities
2

Organization of Nervous System

  • Human neural system divided into: Central Neural System (CNS) and Peripheral Neural System (PNS)
  • CNS includes brain and spinal cord - site of information processing and control
  • PNS comprises all nerves associated with CNS
3

Structure of Neuron

  • Neuron has three major parts: Cell body, Dendrites, and Axon
  • Cell body contains cytoplasm with typical organelles and Nissl's granules
  • Dendrites: Short fibres branching from cell body, contain Nissl's granules, transmit impulses TOWARDS cell body
4

Generation and Conduction of Nerve Impulse

  • Neurons are excitable cells with polarized membranes
  • Resting membrane: More permeable to K+, nearly impermeable to Na+, impermeable to proteins
  • Axoplasm: High K+ and proteins, low Na+
