What are the main functions of the nervous system?
The nervous system has three broad functions: sensory input, information processing, and motor output. In the PNS, sensory receptor neurons respond to physical stimuli in our environment, like touch or temperature, and send signals that inform the CNS of the state of the body and the external environment.
What is the function of the nervous system short answer?
The nervous system is involved in receiving information about the environment around us (sensation) and generating responses to that information (motor responses). The nervous system can be divided into regions that are responsible for sensation (sensory functions) and for the response (motor functions).

What are the three main functions of a nervous system quizlet?
Terms in this set (3)
- sensory input. when sensory receptors monitor changes that occur both inside and outside of the body.

What are the 3 major functions of the spinal cord?
What does the spinal cord do?
- Motor Functions – directs your body’s voluntary muscle movements.
- Sensory Functions – monitors sensation of touch, pressure, temperature and pain.
- Autonomic Functions – regulates digestion, urination, body temperature, heart rate, and dilation/contraction of blood vessels (blood pressure).
Why is the spinal cord so important?
The spinal cord controls various parts of the body and plays an important role when it comes to bladder control.

- Weakness, especially with certain activities.
Does the spinal cord control the heart?
The brain normally controls blood pressure and heart rate. Signals from the brain send messages through the spinal cord to constrict blood vessels and raise the heart rate to keep the blood pressure and heart rate normal. When these signals cannot get through, a person can have low blood pressure and slow heart rate.
