The nervous system has three general functions: a sensory function, an interpretative function and a motor function. 1. Sensory nerves gather information from inside the body and the outside environment. The nerves then carry the information to the central nervous system (CNS). 2. Sensory information brought to the CNS is processed and interpreted. 3. Motor nerve cells convey information from the CNS to the muscles and glands of the body. The nervous system is responsible for coordinating all of the body's activities.</span>
The spinal cord
The spinal cord part of the central nervous system is involved in this automatic response.
The spinal cord is a long, tiny tube of nervous tissue that support cells which passes from the end of the brainstem to the bottom of the spine. The central brain nervous system is made up of the spinal cord and the brain. The spinal cord is the center for coordinating many reflexes and it plays major roles in the transmission of nerve signals (messages) between the brain and the rest of the body.
Osmosis is a vital function to the growth and stability of plant life. Without osmosis, photosynthesis would never occur and plants would wilt and die. Osmosis distributes water through selectively permeable membranes to maintain this proper volume and pressure of all plant cells.
