What eye movement is caused by the superior oblique?
Superior oblique is controlled by cranial nerve VI (Trochlear nerve). This muscle depresses the eye and moves it laterally. A person with damage to this cranial nerve will have difficulty looking down and to the side.
How does the myelin sheath and synapse affect nerve impulses speed up or slow down?
Myelin sheath insulates axons for speedier signaling
What is the thickest cranial nerve?
The scaitic nerve is the longest and largest nerve.
What is the colchlea and what does it do?
the cochlea is a vital part in your inner ear that transforms vibrations coming from the oval window ( preceeding area of inner ear that receives vibrations) into electrochemical impulses and travel down the auditory nerve into the brain for processing.
What part of the brain controls basic life support functions?
The brain stem, which consists of the midbrain, pons, and medulla, ot medulla oblongata - which keeps you breathing and your heart beating in proper rhythm. If your heat needs to slow down the heart is influenced by via cranial nerve X, the Vagus nerve.
What is electroneurography?
The measurement of the speed of conduction of impulses down a peripheral nerve.
Do nerve impulses travel down the internodal pathways from the av node?
no
Saltatory conduction refers to the conduction of impulses in?
It is the "skipping" pattern that impulses follow to travel down nerve axons.
Nerve impulses trAVel down the internodal pathways from the AV node?
No, SA Node
Does the Vagus nerve carry nerve impulses that decrease the heart rate?
The vagus nerve releases the neurotransmitter, aceytlcholine, that slows down the heart rate. It is not the nerve impulses per se that do this, rather it is the the release of transmitter and it's interaction with post-synaptic receptors that have this effect.
What eye movement is caused by the superior oblique?
Superior oblique is controlled by cranial nerve VI (Trochlear nerve). This muscle depresses the eye and moves it laterally. A person with damage to this cranial nerve will have difficulty looking down and to the side.
How do depressants slow down the transmission of nerve impulses?
they stop the signals travelling down the nerves by blokcing the synapses
What are chemicals that retard behavior by either speeding up or slowing down nerve impulses?
hallucinogen
Where do nerve impulses leave the neuron?
Nerve impulses are transmitted down the axon and leave the neuron via the terminal bouton at the synaptic interface, releasing neurotransmitters into the synaptic cleft to affect the post-synaptic cell..
What A wave pattern travels down the length of the axon of a cell.?
A wave pattern travels down the length of the axon of a nerve cell. A nerve cell, also called a neuron, is a specialized cell that transmits nerve impulses.
A wave pattern travels down the length of the axon of what kind of cell?
A wave pattern travels down the length of the axon of a nerve cell. A nerve cell, also called a neuron, is a specialized cell that transmits nerve impulses.
What effect will multiple sclerosis a degenerative disorder that cause myelin to disintegrate have on a person's nerve impulses?
They will slow down
