Describe the structure of a nerve with a diagram. Mention the three types of nerves. View Solution Nerve is a View Solution Mixed nerves carry impulses View Solution Distinguish between the following pairs : Conduction of nerve impulse in myelinated and non myelinated nerve fibres View Solu...
Nerve conduction study.An NCS detects damage to nerves the way an EMG tests muscle function. During the test, the technician puts electrode patches on your skin over the nerve that may be causing your symptoms. A stimulating electrode sends a mild electrical impulse to the nerve. The other el...
Define nerve fiber. nerve fiber synonyms, nerve fiber pronunciation, nerve fiber translation, English dictionary definition of nerve fiber. n. A threadlike process of a neuron, especially the prolonged axon that conducts nerve impulses. American Heritage
-Nerve impulse: electrochemical charge that travels along the nerve fibre. -Impulse speed varies: o Unmyelinated: approx 2m/sec o Myelinated: approx 18m/sec to 140m/sec (through saltatory conduction) This is affected by: diameter of neuron or distance between nodes of ranvier impulse ...
* Nerve impulse is the action potential. * As the axon is involved in the current activity, it cannot respond to any other stimulus. This period is known as the refractory period. Representation of Action PotentialAs the nerve impulse moves along the axon as represented in the image above, ...

intraperiod line. Gaps occur between segments of sheath; these gaps, known as the “nodes of Ranvier,” constitute the foci of electrical activity. Thusmyelinationbrings about saltatory conduction; the electrical impulse is rapidly and efficiently transmitted along an axon by “jumping” from node ...
Release of acetylcholine to these regions typically results in both a decrease in the rate of rhythm of the SA node, as well as a decrease in the cardiac impulse transmission into the ventricles. Consequences of these actions generally include a decrease in heart rate, cardiac output, ...
