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.
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 part of a spinal nerve contains only efferent fibers?
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.
What branch of a nerve carries a message to the brain from a muscle?
afferent
What is the 12 pairs of peripheral nerves that branch out from the brain?
You are speaking of the 12 cranial nerves:I. Olfactory nerve which branches out of the telencephalonII. Optic which branches out of the diencephalonIII. Oculomotor nerve which branches out of the mesencephalonIV. Trochlear nerve nerve which branches out of the mesencephalonV. Trigeminal nerve which branches out of the ponsVI. Abducens nerve which branches out of the ponsVII. Facial nerve which branches out of the ponsVIII. Vestibulochochlear nerve which branches out of the ponsIX. Glossopharangeal nerve nerve which branches out of the medullaX. Vagus nerve nerve which branches out of the medullaXI. Accessory nerve nerve which branches out of the medulla & cervical spineXII. Hypoglossal nerve nerve which branches out of the medulla
What nerve controls swallowing?
The Hypoglossal nerves (XII) carry somatic motor fibers to intrinsic and extrinsic muscles of the tongue. These nerves are mixed, but primarily motor in function. The hypoglossal nerves arise from the Medulla Oblongata.
What nerve innervates all the muscles of the tongue except palatglossus?
hypoglossal nerve
What cranial nerve number is hypoglossal?
12 or XII
What transfers a signal from the afferent nerve to the efferent nerve?
Neurotransmitters are released from the terminal bouton of the afferent nerve, cross the synaptic cleft, and bind with receptors on the efferent nerve. If enough neurotranmitter binds to reach the minimum potential, an action potential is created and the signal moves down the efferent nerve.
Which cranial nerve lies medial to the vagus nerve?
That would be the hypoglossal nerve, which lies medial from the vagus, accessory, glossopharyngeal nerves.
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.
Are efferent nerve fibers also described as motor nerve fibers?
yes
What is another name for motor nerves?
efferent nerve
What nerve is carrying the afferent and efferent impulses during the patellar reflex?
The nerves innervate the quadriceps. The afferent nerves are the muscle spindles and the efferent are the motor neurons.
What nerve controls salivation swallowing and taste?
The trigeminal nerve (the fifth cranial nerve, or simply CN V) is a nerve responsible for sensation in the face and motor functions such as biting and chewing
What are the Nerves that only carry impulses away from the central nervous system called?
efferent nerve
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.
