Answer: seen in the explanation.

Explanation:

Patellar reflex is a stretch reflex which tests the Lumber vertebral 2- 4 segments of the spinal cord.

The major event that occurs after Striking of the patellar tendon with a reflex hammer just below the patella includes;

1) It stretches the muscle spindle in the quadriceps muscle.

2) A signal is produced which travels back to the spinal cord and synapses (without interneurons) at the level of Lumber vertebra 3 in the spinal cord, completely independent of higher centres.

3) After the synapse an alpha motor neuron conducts an efferent impulse back to the quadriceps femoris muscle, triggering contraction.

4) Contraction of the quadriceps femoris muscle, coordinated with the relaxation of the antagonistic flexor hamstring muscle causes the leg to kick.

This is a reflex of proprioception which helps maintain balance and posture.

Testing Two-Point Discrimination
yanalaym [24]
Two-point discrimination is the minimal distance which someone can perceive two different stimuli that given simultaneously. An area with higher receptor density will have a lower two-point discrimination result since the distance between receptor is lower. 
The area that needs a high sensitivity like the palm of the <span>hands(especially the fingertips), face</span>, and tongue should be the one with lowest two-point discrimination.

In this report, a<span>nterior forearm two-point discrimination result is the lower than the fingertip. This result is suspicious since the forearm shouldn't more sensitive than the fingertip. Fingertip two-point discrimination is around 2-6mm and forearm should be much higher than 6mm.
