What type of fibers make up the posterior and anterior roots of the spinal nerve?
Both Afferent and Efferentboth sensory and motorContains motor & sensory fibers!The spinal cord consists of nerve fibers that are afferent and efferent.
Are efferent nerve fibers described as motor nerve fibers?
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.
Which plexus contains the foot and the leg?
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 can contain fibers from?
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.
What is efferent give example?
Efferent refers to nerves that carry signals away from the central nervous system to the body parts, such as motor neurons that control muscle movement. An example of an efferent nerve is the sciatic nerve, which carries signals from the spinal cord to the leg muscles for movement.
What type of fibers make up the posterior and anterior roots of the spinal nerve?
Both Afferent and Efferentboth sensory and motorContains motor & sensory fibers!The spinal cord consists of nerve fibers that are afferent and efferent.
Are efferent nerve fibers also described as motor nerve fibers?
yes
Are efferent nerve fibers described as motor nerve fibers?
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.
Carries impulses between spinal cord and body parts?
CENTRAL
What type of nerve fibers are found in the ventral ramus of a spinal nerve?
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.
The dorsal root of a spinal nerve contain what?
axons of sensory neurons
Spinal nerve contains both motor and sensory nerve fibers for 2-way communications?
yes
CAN reflex action controlled by spinal cord?
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.
Area of spinal cord that contains nerve fibers surrounded by myelin sheath?
the part of the spinal cord that contains mylinated axons is the White matter portion.
What contains the cranial nerve and spinal nerve?
Spinal Accessory Nerve
What type of nerves are spinal nerves Are they Afferent Efferent or Mixed?
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.
Anterior root of the spinal cord is composed of?
The anterior root is composed of nerve fibers responsible for motor activity (i.e. efferent nerve fibers that will stimulate muscles, etc.). I think some of the things it is composed of include:Gamma motor neurons, alpha motor neurons, preganglionic autonomic neurons
