Which of the following is an example of superficial reflexes?

Correct answer: C. Abdominal reflex

  • A. Ankle jerk
  • B. Knee jerk
  • C. Abdominal reflex
  • D. Both Options A and B are correct

Explanation

Option A: Ankle jerk is an example of a deep tendon reflex, which is elicited by tapping the Achilles tendon with a reflex hammer. The ankle jerk assesses the function of the S1 and S2 spinal cord segments and the peripheral nerves that innervate the ankle joint. Option B: The Knee jerk is also an example of a deep tendon reflex, which is elicited by tapping the patellar tendon with a reflex hammer. The knee jerk assesses the function of the L3 and L4 spinal cord segments and the peripheral nerves that innervate the quadriceps muscle. Option C: The abdominal reflex is an example of a superficial reflex stimulated by the stroking of the abdomen around the umbilicus.. Option D: This is not the correct answer.

About Coordination and Control

Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
