What tissue type functions in impulse conduction?
Nervous tissue.
Which of the following types of nerve fiber possesses the fastest speed of impulse propagation?
Type A
Which of the following does not factor into the rate of impulse propagation?
Whether or not the impulse begins in the CNS influences the time necessary for a nerve impulse to be transmitted.
1 List the physiological events that occur between delivery of the stimulus and the start of the recorded response?
The speed of nerve impulse transmission changes as the body ages. In infants, the transmission speed is only about half that seen in adults. By age five, most people have attained the adult velocity. A gradual decline in conduction velocity begins as people reach their 20s, and continues for the remainder of life. Another factor that influences conduction velocity is the length of the nerve itself. An impulse that has to travel a longer distance will take longer. Some nerves are naturally longer than others. Measurement of nerve conduction takes into account the length of the target nerve. Some other factors are: · Initiation of action potential in nerve fibers; · Conduction of impulse; · Release of acetylcholine from the nerve terminals; · Binding of acetylcholine to receptors of the motor end plate; · Depolarization of the end plate; · Initiation of action potential in muscle fibers; · Muscle contraction.
What is the relay station for nerve impulses?
There is no relay station in nerve impulse conduction.
Is the velocity of a nerve impulse greater than electrical conduction's?
yes
What features of nerves improve impulse conduction velocity?
myelin sheaths
The velocity of nerve impulse conduction is greatest in?
Heavily myelinated, large diameter fibers
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 a 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.
How to calculate the speed of propagation of the nerve impulse in a nerve fiber?
The velocity of nerve conduction is usually assessed by dissecting out a nerve fiber from an animal such as a frog. The nerve is placed in a chamber containing stimulating and recording electrodes. The responses of the nerve can be monitored using an oscilloscope. More detail on this procedure can be found in the related link.
What is impulse conduction?
Party of nervous
The special mode of impulse travel is called?
Propagation
Does nerve conduction use ATP?
True- it is a multifunctional nucleoside triphosphate that is used in cells as a coenzyme, and serves as a substrate in nerve impulse propagation.
What is impulse propagation?
It is the traveling of the electrical signal down the length of a neuron.
What is the difference between impulse conduction and transmission?
Impulse conduction refers to passage of impulse within the same cell. Where as transmission as the name implies, is concerned about passage of impulses either chemical or electrical from one cell to another.
If the velocity is constant does that mean that the impulse is the momentum?
impulse = change in momentum so, no
