Final answer:
Sensory neurons contain axons that bring sensory information into the spinal cord. These neurons have projections ending in sensory receptors and another that synapses in the dorsal spinal cord. Motor neurons, located in the ventral gray matter of the spinal cord, project to muscle, allowing the transmission of sensory and motor information.
Step-by-step explanation:
The sensory information from the body is conveyed to the spinal cord through structures formed by the axons of sensory neurons. The sensory neuron cell bodies are grouped in structures called dorsal root ganglia. These sensory neurons have projections that end in sensory receptors in the skin, muscle, or sensory organs and another projection that synapses with a neuron in the dorsal spinal cord.
Motor neurons have cell bodies in the ventral gray matter of the spinal cord that project to muscle through the ventral root. These neurons are usually stimulated by interneurons within the spinal cord but are sometimes directly stimulated by sensory neurons.
Spinal nerves are thus responsible for transmitting sensory and motor information between the spinal cord and the rest of the body. Each of these nerves contains both sensory and motor axons.
