Spinal cord

Answer 1

• The spinal cord is the part of the central nervous system and it is held within the vertebral column. 
• It is slightly thick but gradually tapers towards the end. 
• There is a thread like fibrous structure at its end. It is called the filum terminale. 
• The long tubular cavity of the spinal cord is called the central canal. It is filled with cerebrospinal fluid. 
• The spinal cord conducts impulses from the skin towards the brain and from the brain to the muscles and glands. 
• It functions as a centre of co-ordination of reflex actions.
