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