Topics in Neural Control and Coordination

1

1. Overview of the Neural System

  • The neural system of all animals is composed of highly specialised cells called neurons which can detect, receive and transmit different kinds of stimuli.
  • In mammals, the nervous system is divided into the central nervous system and the peripheral nervous system.
  • The central nervous system consists of the brain and spinal cord.
2

2. Brain: Structure and Major Parts

  • The human brain is the central information processing organ of the body.
  • It weighs about 1,350 g in an average adult.
  • It is made up of about 1,000 billion neurons and neuroglia.
3

3. Spinal Cord and Spinal Nerves

  • The spinal cord is the downward continuation of the medulla oblongata.
  • It descends through the vertebral canal and ends at the lower border of the first lumbar vertebra.
  • The spinal cord has cervical and lumbar enlargements.
4

4. Nerve Fibres, Nerves and Synapse

  • Nerve fibres are axons or dendrites enclosed by a connective tissue sheath.
  • Nerve fibres are classified into myelinated and non-myelinated fibres.
  • Non-myelinated fibres lack a myelin sheath.
