Question 0

Place the elements of the patella tendon reflex are in the correct order. The strike on the patella tendon is first.

Answer 0

1 = strike on patella tendon
2 = muscle spindle is stretched
3 = afferent impulses from stretch receptor to spinal cord
4 = synapse with interneurone
5 = efferent impulses generated in motor neurone
6 = impulses sent along motor neurone to flexor muscle
7 = impulses arrive at motor synapse with muscle
8 = flexor muscle contracts
9 = leg jerks upwards
