Coordination and regulation

Coordination and regulation

The nervous system


The nervous system
The nervous system

  • The nervous system is composed of excitable cells called neurones (also neurons)

  • Neurones, characteristically, have long thin extensions which carry electrical nerve impulses

  • This electrical signal of the nerve impulse needs to be converted into a chemical signal (a neurotransmitter) so that it can pass from nerve cell to nerve cell


The nervous system organisation

Central Nervous System

Motor nerve

Sensory nerve

Effector

eg muscle or gland

Receptor or Sensor

eg photoreceptor

Stimulus

Response

The nervous system organisation

  • A Central Nervous System (CNS) made of the brain and spinal cord…

  • and peripheral nerves connecting it to sensors and effectors
