Vedclass · Answer

(A) In mammals,each spinal nerve is connected to the spinal cord by two roots: the dorsal root and the ventral root.The dorsal root contains sensory (afferent) nerve fibres that carry impulses from the body towards the spinal cord.The ventral root contains motor (efferent) nerve fibres that carry impulses away from the spinal cord to the effectors.Specifically,the ventral root consists of somatic motor fibres (which innervate skeletal muscles) and visceral motor fibres (which innervate smooth muscles,cardiac muscles,and glands).Therefore,the correct option is $A$.
