Question Parts

( a )
Outline the neural pathway that carries the visual information of the whistle from the retina to the forearm muscles that contract to stop the ball. Mention the receptor, afferent neuron, central processing stations, interneuron (if any), efferent neuron and the target muscle fibre.
( b )
Compare the speed of this voluntary movement with the rapid withdrawal reflex that occurs when a person touches a hot surface. Explain why the reflex is faster, referring to the number of synaptic connections involved.
( c )
Explain the role of the cerebellum in fine‑tuning the player’s movements during the dribble and sudden change of direction. Include the type of information it receives and how it influences motor output.
