Answer
The three fundamental functions of the nervous system are sensory, interpretative, and motor.
Receptors are used for the sensory function. Receptors sense changes both within the body and out in the environment. Receptors send these signals up the CNS to be interpreted. Once the signals are interpreted and a decision is made on what to do, a signal comes down to the effectors to carry out the decision.
Work Step by Step
The three fundamental functions of the nervous system are:
Sensory – Using receptors, the nervous system receives information about changes in the body and external environment and transmits messages to the CNS.
Interpretative – The CNS processes this information and determines what response is appropriate to the circumstance.
Motor – The CNS issues commands, primarily to effectors, to carry out the response.
Receptors work for the sensory function and gather and send all the information to the CNS. Effectors receive and carry out the responses as determined by the CNS.
