Control and coordination in mammals

Need to know

What you need to know

• **Sensory Neurones:** Transmit impulses from sensory receptors (e.g., in skin or eyes) to the CNS. They have a long dendron and a short axon.
• **Motor Neurones:** Transmit impulses from the CNS to effectors (muscles or glands). They have a long axon and many short dendrites.
• **Relay Neurones (Interneurones):** Found entirely within the CNS, they transmit impulses between sensory and motor neurones. They have a short axon and many dendrites.

Explanation

Control and coordination in mammals

1. **Sensory Neurones:** Transmit impulses from sensory receptors (e.g., in skin or eyes) to the CNS. They have a long dendron and a short axon.
2. **Motor Neurones:** Transmit impulses from the CNS to effectors (muscles or glands). They have a long axon and many short dendrites.
3. **Relay Neurones (Interneurones):** Found entirely within the CNS, they transmit impulses between sensory and motor neurones. They have a short axon and many dendrites.
