Keeping this in view, what nerve is tested in the Achilles reflex?

The Achilles Reflex (see below) is dependent on the S1 and S2 nerve roots. Herniated disc material (a relatively common process) can put pressure on the S1 nerve root, causing pain along its entire distribution (i.e. the lateral aspect of the lower leg).

Also Know, what muscles are involved in the Achilles reflex? Achilles Reflex

Considering this, what nerve Innervates the Achilles tendon?

The Achilles tendon derives its innervation from the sural nerve with a smaller supply from the tibial nerve.

What is the result of the Achilles reflex?

The ankle jerk reflex, also known as the Achilles reflex, occurs when the Achilles tendon is tapped while the foot is dorsiflexed. A positive result would be the jerking of the foot towards its plantar surface. Being a deep tendon reflex, it is monosynaptic. It is also a stretch reflex.
