Study Notes
Neurone Types
- Three main types of neurons: sensory, motor, relay
- All have a long axon, insulated by a myelin sheath for efficient long-distance signal transmission.
- Axons are very long
Neurone Structure
- Tiny branches (dendrons) extend out from the neuron, which further branch into dendrites.
- Dendrites receive impulses from other neurons.
Effectors
- Effectors (muscles and glands) produce responses to stimuli
- Examples of effector responses:
- Glands releasing hormones into the bloodstream (e.g., adrenaline, insulin)
- Muscles contracting (e.g., leg movement)
- Muscles secreting substances (e.g., saliva from salivary glands)
