What else can I help you with?
What are the neurons that conduct the nerve impulses from the spinal cord and the brainstem to the thalamus called?
afferent nerves of the ascending spinal pathways.
Why a peripheral nerve such as the sciatic nerve can contain nerve fiber from several spinal nerves?
The reason why a peripheral nerve such as the sciatic nerve can contain nerve fiber from several spinal nerves is owing to nerve plexuses. These are networks of nerves all tangled together and found mostly in the limbs.
Damage to this fiber type would lead to a loss of sensory function?
ventral root of a spinal nerve
Which of the following is not a nerve plexus?
The spinal nerve is not a nerve plexus. Nerve plexuses are complex interwoven networks of nerves that form in the peripheral nervous system, whereas spinal nerves are the mixed nerves that emerge from the spinal cord and are not organized in a plexus-like fashion.
What contains the cranial nerve and spinal nerve?
Spinal Accessory Nerve
What are some parts of the frog's nervous system?
Olfactory nerve, Optic nerve, Nasal sack, Trigeminal nerve, Gasserian ganglion, Facial nerve, Auditory nerve, Tympanic membrane, Glossopharyngeal nerve, pneumogastric nerve, First spinal nerve, Branchial enlargement, Branchial nerve, Third spinal nerve, fourth spinal nerve, fifth spinal nerve, sixth spinal nerve, seventh spinal nerve, eighth spinal nerve, ninth spinal nerve, tenth spinal nerve, Femoral nerve, Sciatic nerve, Sympathetic nerve trunk, Lumbar enlargement, Sympathetic ganglia, and Filum terminale.
Where does the spinal nerve take nerve impulses?
the spinal nerve sends nerve impulses away from the CNS
What is the difference between ascending and descending impulses?
Ascending impulses refer to nerve signals traveling towards the brain, carrying sensory information from the body. Descending impulses, on the other hand, refer to nerve signals traveling from the brain down the spinal cord to control motor functions and movement in the body.
What is the function of the nervers?
Basically, a nerve is a fiber that connects the brain and spinal cord with various parts of the body (aka - receptor organs).
What is the function of the nerver?
Basically, a nerve is a fiber that connects the brain and spinal cord with various parts of the body (aka - receptor organs).
A myelinated nerve fiber is characterized as being whereas an unmyelinated?
Myelinated nerves are white, and composes the white matter of the brain and spinal cord they also are able to pass an action potential down an axon much faster; Unmyelinated nerves are gray, and composes the gray matter of the brain and spinal cord. These nerves transmit signals much slower
Fiber type in anterior ramus?
alpha spinal motor neuron axons leave the spinal column and enter the nerves via the ventral rami.
