The correct answer is C. (Ik it's correct because I just answered it)
The spinal cord contains ascending and descending nerve fibres that send information between the CNS and the periphery. This illustrates the conduction function of the spinal cord.
The bony components of the vertebral column serve to shield the spinal cord, which is a component of the central nervous system (CNS) and which spans from the head to the tail of the body. It is protected by the three membranes that make up the central nervous system, which are the pia mater, the arachnoid, and the dura mater.
The spinal cord contains the descending and ascending nerve fibres. The spinal cord is an important component of both the central nervous system and the peripheral nervous system. It is connected to the rest of the nervous system by a network of 31 pairs of spinal nerves, which are responsible for carrying sensory information. These nerves go up the spinal cord or through the medulla oblongata to reach the subcortical nuclei, where they form synaptic connections.
