The spinal cord has a segmental organization, and as a result: A. Each posterior (dorsal) spinal root innervates muscles found in the arms and legs, and this is referred to as a myotome. B. Each posterior (dorsal) spinal root carries sensory information from a specific area of skin, referred to as a dermatome. C. Efferent (motor) neurons in the posterior (dorsal) horn innervate muscles and organs from a single spinal cord segment. D. All sensory information from the periphery enters the spinal cord through the anterior (ventral) horn.
