Final answer:
Sensory nerves are responsible for carrying messages from the body to the brain. They transmit sensory information to the central nervous system and include both cranial and spinal nerves.
Step-by-step explanation:
Messages from the body to the brain are carried by sensory nerves . These nerves are responsible for transmitting sensory information from the skin, skeletal muscle, and sensory organs to the central nervous system (CNS). The nervous system includes both the sensory - sonatic nervous system , which consists of cranial and spinal nerves containing sensory neurons, and the motor neurons responsible for movement. Sensory neurons have only one synapse, with one end at the sensory organ and the other end making direct contact with a CNS neuron. The sensory fibers, which can be part of either spinal nerves or cranial nerves, convey information to the CNS for processing.
