The ventral root of the spinal nerve has the efferent fibers and the dorsal root has the afferent. Prior to joining each other in the spine they each consist of only those fibers.
Both Afferent and Efferentboth sensory and motorContains motor & sensory fibers!The spinal cord consists of nerve fibers that are afferent and efferent.
Yes, efferent nerve fibers are often described as motor nerve fibers. Efferent nerves carry signals away from the central nervous system to muscles and glands, controlling movement and bodily functions.
General somatic efferent (GSE) fibers are motor nerve fibers that originate in the spinal cord and are responsible for innervating skeletal muscles. They transmit signals from the central nervous system to the muscles, facilitating voluntary movements. GSE fibers are part of the peripheral nervous system and play a crucial role in controlling motor functions, such as walking and fine motor skills. These fibers are primarily associated with the lower motor neurons found in the spinal cord and brainstem.
The lumbar plexus contains nerve fibers that innervate the leg, and the sacral plexus contains nerve fibers that innervate the foot. The lumbar plexus arises from the lower spinal cord levels, while the sacral plexus arises from the sacral spinal cord levels.
The brachial plexus contains fibers from the ventral rami of the cervical spinal nerves (C5-C8) and the first thoracic spinal nerve (T1). These fibers combine to form the nerves that innervate the upper limb.

CENTRAL
axons of sensory neurons
The ventral ramus of a spinal nerve contains both sensory and motor nerve fibers. These fibers innervate the muscles, joints, and skin on the front part of the body.
yes
Simple reflexes are controlled by the spinal cord. The message travels from the sense receptors near the skin through the afferent nerve fibers to the spinal cord. In the spinal cord, the messages are relayed through association neurons to the efferent nerve fibers, which carry them to the muscle cells that cause the reflex movement.
the part of the spinal cord that contains mylinated axons is the White matter portion.
Spinal Accessory Nerve
General somatic efferent (GSE) fibers are motor nerve fibers that originate in the spinal cord and are responsible for innervating skeletal muscles. They transmit signals from the central nervous system to the muscles, facilitating voluntary movements. GSE fibers are part of the peripheral nervous system and play a crucial role in controlling motor functions, such as walking and fine motor skills. These fibers are primarily associated with the lower motor neurons found in the spinal cord and brainstem.
Spinal nerves are mixed nerves, meaning they contain both afferent (sensory) and efferent (motor) nerve fibers. This allows them to transmit both sensory information from the body to the central nervous system and motor commands from the central nervous system to the body.
