RECEPTION, RESPONSES AND CO¬ORDINATION IN ANIMALS

  • The nervous and endocrine systems (together known as the neuro-endocrine system) act as a co-coordinating system.
  • They linking the receptors to the effectors and regulating their activities.

Receptors

  • Receptors are cells that detect or receive stimuli.
  • They may be scattered more uniformly all over the body surface e.g. receptors for pain, touch, temperature; or they may be located in a special sense organ e.g. receptors for light, sound, taste and smell.
  • Motor nerves link the Central Nervous System (CNS) to the effectors.
  • Its cell body is located at one end of the axon.
  • It transmits nerve impulses from the CNS to the effectors.

Effectors

  • These are the cells, organs, or organelles which enable the organism to respond.
  • They include muscles, glands, cilia and flagella.
