What is the neural pathway involved in the Achilles tendon reflex?
The Achilles tendon is innervated primarily by the S1 and S2 nerve roots of the Tibial nerve.
What nerve root does the Achilles reflex test?
and the Achilles reflex or ankle jerk reflex, mediated by S1 through the sciatic (tibial) nerve and elicited by tapping the tendon of the gastrocnemius muscle (Fig. 33.22D).
Is the Achilles reflex somatic or autonomic?

What level of the spinal cord is involved in the Achilles reflex?
[4] The LMN structures are the ventral (anterior) horn of the spinal cord and the peripheral nerve that innervates the muscle. The LMN of the Achilles reflex consists of the ventral horn of the S1 nerve root and the tibial nerve.
What is the difference between autonomic and somatic reflexes?
The main difference between the somatic and autonomic systems is in what target tissues are effectors. Somatic responses are solely based on skeletal muscle contraction. The autonomic system, however, targets cardiac and smooth muscle, as well as glandular tissue.
What nerve carries the afferent and efferent impulses in the knee jerk reflex?
femoral nerve
The quadriceps femoris reflex also called the patellar reflex, is elicited by inducing rapid stretch in the common quadriceps tendon distal to the patella (technically the patellar ligament, but in this functional context, the quadriceps femoris tendon), sending an afferent action potential to the spinal cord via the …
What controls deep tendon reflexes?
The deep tendon reflex depends on the integrity of both the upper motor neuron and the lower motor neuron. As a general rule, disease/injury of the lower motor neuron (e.g., nerve roots or peripheral nerves) will cause a reduction or loss of a reflex.
Why is the Achilles reflex important in walking?
The Achilles tendon (AT) has the capacity to store and release elastic energy during walking, contributing to metabolic energy savings.
