Question

The cremasteric reflex tests nerve roots L1 and L2. What happens when L1 and L2 are tested?

1) The testicles move
2) The patient feels pain
3) The patient loses sensation in the legs
4) The patient experiences muscle weakness

Answer 1

The cremasteric reflex tests nerve roots L1 and L2, causing the testicles to move.

Step-by-step explanation:

The cremasteric reflex is a reflex that tests the nerve roots L1 and L2. When these nerve roots are tested, the testicles move. The cremaster muscle, which is controlled by these nerve roots, contracts and raises the testicles in response to the stimulus. This reflex is important for temperature regulation and protection of the testicles.
