What part of the spinal cord carries sensory information?
Spinal Cord Nerve Branches
The posterior root is the sensory (afferent) root that carries sensory information to the brain from other areas of the body. The anterior root is the motor (efferent) root that carries motor information to the body from the brain.
What receives sensory information from the spinal nerve?
The cerebellum receives somatosensory input from the spinal cord, motor information from the cerebral cortex and balance information from the vestibular organs of the inner ear.
Where do sensory nerves enter the spinal cord?
Sensory spinal nerves enter the spinal cord on the back (dorsal) side, whereas motor spinal nerves exit the spinal cord on the front (ventral) side. The cell bodies of sensory nerves lie outside the spinal cord within the dorsal root ganglia, whereas the cell bodies of motor nerves lie within the spinal cord.
Which spinal nerves affect which parts of the body?
The nerves of the cervical spine go to the upper chest and arms. The nerves in your thoracic spine go to your chest and abdomen. The nerves of the lumbar spine then reach to your legs, bowel, and bladder. These nerves coordinate and control all the body’s organs and parts, and let you control your muscles.
What information is processed in the spinal cord?
The spinal cord acts as the body’s telephone system, relaying information from the brain to the rest of the body, and sending signals about the rest of the body to the brain.
What is the root of a spinal nerve?
The dorsal root of spinal nerve (or posterior root of spinal nerve or sensory root) is one of two “roots” which emerge from the spinal cord. It emerges directly from the spinal cord, and travels to the dorsal root ganglion. Nerve fibres with the ventral root then combine to form a spinal nerve.
