Question

Which of the following is an example of a somatic reflex:

Group of answer choices

Sensory neurons detect decreased blood pressure; motor neurons increase heart rate

Sensory neurons detect painful stimulus on finger; motor neurons cause arm to pull away

Sensory neurons detect stomach stretch; motor neurons cause increased stomach motility (activity)

Sensory neurons detect decreased blood pressure; motor neurons cause vasoconstriction (blood vessels constrict)

Answer 1

Example of somatic reflex is- sensory neuron detect painful stimulus on finger, and motor neuron cause arm to pull away.

The other three options are the examples of the involuntary actions of the body, which are not in our control. These actions are controlled by the autonomic nervous system.

Control of skeletal muscles like in case of removal of hand when there is any painful stimulus, is an example of voluntary action. All the voluntary actions of our body are controlled by the somatic division of nervous system.
