When something like a hot object touches your hand, your receptors send impulses down the sensory neurone which then takes the impulses to the relay neurone (co-ordinator) which then sends the impulses to the motor neurone which goes in the opposite direction to an effector organ. This then reflexes your hand away from the hot object.

Reflex actions are involuntary and immediate reactions to a stimulus.

Two examples are:

  1. Pulling your hand away from a hot object (this is a spinal reflex action)
  2. The 'knee jerk' - when the tendon just below the knee is tapped, it causes the thigh muscle to suddenly contract and the foot kicks forward. (this is a stretch reflex action)

-------------------------------------------


A reflex action is a sudden reaction to a stimuli (a change in the environment) & often acts to protect you.


Some are controlled by the brain (cranial reflexes) such as when you blink as dust lands in your eye, or your pupil gets smaller as light is shone in your eye.


Some reflexes are controlled by the spinal cord (spinal reflexes) such as when you touch a hot object or stand on a pin.


Some reflexes can have learnt responses so they are calledconditioned reflexes. These reflexes occur without you even thinking about them e.g. walking & producing saliva when you smell food.

One example of a reflex is when your leg jerks after a doctor hits it with a hammer.
