Is reflex action autonomic or somatic?
Reflex arcs that impact the organs are called autonomic reflex arcs, while those that affect the muscles are referred to as somatic reflex arcs.
What type of reflex is ankle jerk?
The ankle jerk reflex, also known as the Achilles reflex, occurs when the Achilles tendon is tapped while the foot is dorsiflexed. It is a type of stretch reflex that tests the function of the gastrocnemius muscle and the nerve that supplies it.
Which nerve is tested with the ankle jerk reflex?
S1 nerve root
The ankle jerk reflex is mediated by the S1 nerve root. The plantar reflex (Babinski) is tested by coarsely running a key or the end of the reflex hammer up the lateral aspect of the foot from heel to big toe.
What is an example of a somatic reflex?
Somatic Reflex Examples A touch on the roof of the mouth by the sucking tongue causes swallowing to occur (allowing baby to obtain nourishment). A stroke along the side of the sole of the foot causes the foot to grasp, moving the toes toward the heel. Sharp, sudden pain causes the affected arm or leg to be withdrawn.
What is autonomic and somatic reflex?
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 is somatic and autonomic?
Somatic Nervous System is the one that allows conscious (voluntary) control of skeletal muscles. Autonomic N. S. has the unconscious (involuntary) control of the body and it has 2 branches, the Sympathetic and Parasympathetic NS.

What is the difference between the autonomic and somatic nervous system?
The somatic nervous system is associated with activities traditionally thought of as conscious or voluntary. The autonomic nervous system controls our internal organs and glands and is generally considered to be outside the realm of voluntary control.
What is somatic reflex?
Somatic reflexes involve specialized sensory receptors called proprioceptors that monitor the position of our limbs in space, body movement, and the amount of strain on our musculoskeletal system. The effectors involved in these reflexes are located within skeletal muscle.
What does it mean to have an ankle jerk reflex?
Ankle jerk reflex. The ankle jerk reflex, also known as the Achilles reflex, occurs when the Achilles tendon is tapped while the foot is dorsiflexed. It is a type of stretch reflex that tests the function of the gastrocnemius muscle and the nerve that supplies it. A positive result would be the jerking of the foot towards its plantar surface.
What’s the best way to do a somatic reflex?
Leg should jerk forward. (somatic reflex) Remove shoes, then dorsiflex slightly to increase the tension of the gastrocnemius muscle. Then slightly tap the calcaneal tendon with the broad side of the reflex hammer. Foot should plantar flex. Nice work!
What does it mean when you jerk your foot?
It is a type of stretch reflex that tests the function of the gastrocnemius muscle and the nerve that supplies it. A positive result would be the jerking of the foot towards its plantar surface. Being a deep tendon reflex, it is monosynaptic.
What is the grade of the Achilles reflex?
A positive response is marked by a brisk plantarflexion of the foot. The response is also graded into Grade 0-4 according to the reflex grading system. The Achilles reflex checks if the S 1 and S 2 nerve roots are intact and could be indicative of sciatic nerve pathology.
