afferent/sensory neurons
The afferent division of the PNS carries impulses inward to a central organ or section, as nerves that conduct impulses from the periphery of the body to the brain or spinal cord
True
from spinal nerve to posterior (dorsal) root
Sensory impulses are typically in the form of electrical signals that travel along nerve fibers from sensory receptors to the brain or spinal cord. These impulses carry information about sensations such as touch, temperature, pain, and pressure. The brain then processes these impulses to generate a conscious perception of the sensory input.
Sensory neurones carry impulses to the CNS, motor neurones carry impulses to muscles.
Sensory Neurons
The midbrain is the final piece of the brain stem. This section deals with motor and sensory nerve bundles.These nerves carry impulses from the cerebral cortex to the pons and the spinal cord. The midbrain also contains nerves that conduct energy to the thalamus.

sensory neurons
Sensory receptors, such as photoreceptors in the eyes, mechanoreceptors in the skin, and chemoreceptors in the nose, are responsible for converting sensory messages (like light, pressure, and chemicals) into neural impulses. These neural impulses are then transmitted to the brain for processing and interpretation.
