Question

All of the following are functions of the peripheral nervous system except

it interprets signals from the external environment
it sends signals to the internal organs
it receives messages from the central nervous system
it sends messages directly to muscles and glands

Answer 1

The function of the peripheral nervous system that does not match is 'it interprets signals from the external environment,' as this is a role of the central nervous system.

Step-by-step explanation:

All of the following are functions of the peripheral nervous system (PNS) except it interprets signals from the external environment. The PNS indeed sends signals to the internal organs, receives messages from the central nervous system (CNS), and sends messages directly to muscles and glands. However, interpreting signals from the external environment is typically a function of the CNS, which includes the brain and the spinal cord where information is processed and interpreted. The PNS serves primarily as a communication relay, carrying sensory information to the CNS and delivering motor commands from the CNS to various parts of the body.

Answer 2

The right option is; it interprets signals from the external environment

The peripheral nervous system (PNS) is made up of all parts of the nervous system, except the brain and spinal cord (parts of the central nervous system). The peripheral nervous system functions as a channel through which neural signals are transferred from and to the central nervous system. Two types of neurons (sensory and motor neurons) functions in the PNS. The motor neurons transfer neural signals from the central nervous system directly to various muscles, glands, and organs (effectors) throughout the body.
