Final answer:
The gag reflex and the withdrawal reflex are two other somatic spinal reflexes similar to the calcaneal tendon reflex and are mediated at the spinal cord level. Hence option B is correct.
Step-by-step explanation:
Two other somatic spinal reflexes that are mediated at the spinal cord level, besides the calcaneal tendon reflex, are the gag reflex and the withdrawal reflex. The gag reflex is a protective reflex involving the contraction of the muscles in the back of the throat, triggered by stimulation of the soft palate or the back of the tongue. It is mediated at the level of the medulla oblongata in the brainstem.
The withdrawal reflex is a rapid, automatic response to a painful stimulus. For example, if you touch a hot object, the withdrawal reflex causes you to quickly pull your hand away. This reflex is mediated at the spinal cord level and involves a sensory neuron detecting the painful stimulus and a motor neuron causing the muscle contraction for withdrawal.Hence option B is correct.
