The dorsal roots of spinal nerves contain sensory neuron axons that conduct impulses from the periphery into the spinal cord. These axons transmit sensory information, such as touch, pain, and temperature, from the body's tissues to the central nervous system for processing. Each dorsal root contains the cell bodies of sensory neurons, which are located in the dorsal root ganglia.
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
This description refers to sensory nerves, specifically those that carry afferent impulses from sensory receptors in the skin to the central nervous system. These axons are responsible for transmitting information about touch, temperature, pain, and pressure. They play a crucial role in the body’s ability to perceive and respond to environmental stimuli.
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.
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.
