What are the functions of spinal cord?
The spinal cord functions primarily in the transmission of nerve signals from the motor cortex to the body, and from the afferent fibers of the sensory neurons to the sensory cortex. It is also a center for coordinating many reflexes and contains reflex arcs that can independently control reflexes.
What two functions does the spinal cord have?
The spinal cord is the highway for communication between the body and the brain. When the spinal cord is injured, the exchange of information between the brain and other parts of the body is disrupted.
What is the structure and function of the spinal cord?

The spinal cord is a complex organization of nerve cells responsible for movement and sensation. It carries signals between the brain and the rest of the body.
What are 3 jobs of the spine?
The three main functions of the spine are to:
- Protect the spinal cord, nerve roots and several of the body’s internal organs.
- Provide structural support and balance to maintain an upright posture.
- Enable flexible motion.
What is the function of spinal cord Class 10?
The spinal cord’s major functions include: Electrochemical communication. Electrical currents travel up and down the spinal cord and across nerves, sending signals which allow different segments of the body to communicate with the brain. Walking.
What are the functions of spinal cord Class 9?
The main functions of the spinal cord are:
- To conduct reflexes below the neck.
- To conduct messages from the skin and muscles to the brain.
- To conduct commands from the brain to muscles of the trunk and limbs.
What is the basic structure of the spinal cord?
The spinal cord is a cylindrical structure of nervous tissue composed of white and gray matter, is uniformly organized and is divided into four regions: cervical (C), thoracic (T), lumbar (L) and sacral (S), (Figure 3.1), each of which is comprised of several segments.
