Sensory Neurones

• What does the sensory neurone do in a reflex action?

  The sensory neurone sends nerve impulses to the spinal cord.
• What is the role of receptors in the nervous system?

  Receptors detect changes in the environment and stimulate electrical impulses in response
• What are sensory receptors?


  Specialised cells or structures that detect and respond to specific types of sensory stimuli, such as light, sound, touch, taste, and smell.
• What happens when the sensory receptor detects a change?


  Once the change is detected, the information is converted to an electrical signal and is sent through a sensory neurone
• Which neurone is the first in the circuit?

  Sensory neurone
• What do sensory neurones do?


  Send impulses from the receptor to the CNS
• Which colour label shows the receptor cells?


  Green

• What does a dendron do?


  Receive information from other neurones
• What does a cell body do?


  Main part of a neurone that contains the nucleus and lots of dendrons + dendrites
• What does an axon do?


  Carry information across the body
