What is nerve conduction velocity test?
Nerve conduction velocity test-- A test that measures the time it takes a nerve impulse to travel a specific distance over the nerve after electronic stimulation.
What is salutatory conduction?
Saltatory conduction refers to the propagation of action potentials along myelinated axons from one node of Ranvier to the next node. It increases the conduction velocity of action potentials.
Which meduim is the velocity of a sound wave the greatest?
The velocity of sound is the highest when travelling through a solid. Sound travels fastes in a solid, then in a liquid, and slowest through a gas.
Which process conduction convection or radiation is used to remove heat from car raditor?
Its actually conduction - to the air passing through (due to the fan ... or the forward velocity of the car).
What are two properties determine the conduction velocity in a mammalian neuron?
Axon diameter and the leak resistance of the membrane. You're welcome Physio students.
The velocity of blood is slowest in the?
capillaries.
What do nerve conduction velocity studies?
Nerve conduction velocity studies (NCV) are used to measure the speed with which an electrical signal is transferred along the nerve.
Who invented the nerve conduction velocity test?
fffhfffhddhhffh
What are the factors which affect the nerve conduction velocity?
The factors affecting nerve conduction velocity are as follows:(i) Axon diameter:An axon with a larger diameter conducts faster. In an unmyelinated fiber, the speed of propagation is directly proportional to the square root of the fiber diameter (D), i.e.,Conduction velocity a D(ii) Myelination and saltatory conduction:Myelination speeds up conduction. Thus, the action potential travels electrotonically along the long myelinated segments, and fresh action potentials are generated only at the nodes. This is called saltatory conduction. In a myelinated neuron, the conduction velocity is directly proportional to the fiber diameter (D).(iii) Temperature:A decrease in temperature slows down conduction velocity, (iv) Resting membrane potential. Effect of RMP changes on conduction velocity is quite variable. Usually, any change in the RMP in either direction (hyper polarization or depolarization) slows down the conduction velocity.
What is the relationship between nerve size and conduction velocity?
velocity proportional to square root of diameter
Where is deposition dominant in a stream?
On the inner curve of a meander, where the velocity of the water is the slowest.
What is nerve conduction velocity test?
Nerve conduction velocity test-- A test that measures the time it takes a nerve impulse to travel a specific distance over the nerve after electronic stimulation.
Earth spins on an axis but which part of earth spins the slowest?
The Earth's rotation
What is the relationship between size of nerve and conduction velocity?
For unmyelinated nerves there is a relationship between axon diameter and conduction velocity. Larger diameter nerves conduct faster. For myelinated nerves the a larger diameter nerve will conduct faster between the nodes of ranvier where the action potential is propagated. Conduction is said to be saltatoryas it jumps from node to node.
Where would the velocity of flow be the slowest in the vascular system if you had a wound in the arm and neck?
arm
Why does neptune have the slowest orbital velocity?
because it is one of the lightest planet and it is not that close to the sun
Is the velocity of a nerve impulse greater than electrical conduction's?
yes
