Question

Which is NOT a sensory function of the nervous system?a.to detect a drop in external temperature.b.to detect an increase in blood pH.c.to cause a muscle to contract.d.to send information to the central nervous system.e.to send information to the spinal cord.

Answer 1

C

Sensory neurons convert environmental stimuli into action potential and send the signal to the central nervous system where the signal is processed into information. All the choices except C are carrying signals from sensory.

Explanation:

Based on information from the sensory neurons, the central nervous systems ‘fires’ the motor neurons to move the muscles. This is why the muscles of the iris are able to contract during low light and relax during bright light. The brightness of light is the stimuli that are carried to the brain by the optical sensory neurons. The CNS processes the information and sends information to the iris muscle via the optical motor neurons.
