2024年1月8日 · Nerve fiber, also known as an axon, is a long, thin projection found on nerve cells (neurons) responsible for nerve impulses' conduction through the nerve cell body. Nerve fibers show properties including conductivity, velocity, refractive period, summation, and accommodation.

A nerve fibre, also called an axon, is a long and slender projection of nerve cells (or neurons) that carry electrical impulses away from the nerve cell body. A neuron typically has one nerve fibre emanating from its cell body that transmits impulses to other neurons, muscles or glands.

Nerve fibers can be classified based on different criteria: 1. Histologically, as myelinated or non-myelinated (Fig. 2.2). 2. Functionally, as afferent (sensory) or efferent (motor). 3. Based on diameter and conduction velocity which is known as Gasser and Erlanger’s classification.

2023年8月12日 · Nerve fibers are classified by six methods: Nerve Fibers Depending upon diameter and conduction of the impulse (Erlanger-Gasser classification). Read And Learn More: Medical Physiology Notes. Myelinated Nerve Fibers: Myelinated nerve fibers are the nerve fibers that are covered by myelin sheath.

2024年4月16日 · In the skin, muscles, and internal organs, nerve fibers transmit signals between nerves and receptors in a thread-like manner. Nerve impulses are what conduct signals from the nerves to the body, or in other words, delivering nerve signals from the nerves to the body.

The important properties of nerve fibres include conductivity, refractive period, accommodation and summation. These fibres are classified based on velocity, diameter and central nervous system. Damage to nerve fibers may occur from trauma, inflammation, infection, or reduced cerebral blood supply.

2021年1月31日 · Nerve fibers are three types which are group A nerve fibers, group B nerve fibers, and group C nerve fibers. Excitability is the power of responding to a stimulus, and stimulus is a sudden change in the external or internal environment. stimuli may be electrical, chemical, mechanical, or thermal. The effectiveness of a stimulus depends on:
