- Erlanger and Gasser classification is a classification of nerve fibers based on the diameter and velocity of impulse conduction1. The nerve fibers are classified into A, B and C types, with A further divided into A alpha, A beta, A gamma and A delta fibers1. Joseph Erlanger and Herbert Gasser studied the properties and distribution of nerve fibers in the 1920s and divided nerve fibers into two different types with different thicknesses2. They showed that the thicker fibers convey nerve impulses faster2.

And A is further divided in to A alpha, A beta, A gamma and A delta fibers. This classification is known as Erlanger and Gasser classification. Diameter and conduction velocity have direction relationship.

Group A nerve fibers are one of the three classes of nerve fiber as generally classified by Erlanger and Gasser. The other two classes are the group B nerve fibers, and the group C nerve fibers. Group A are heavily myelinated, group B are moderately myelinated, and group C are unmyelinated.
The other classification is a sensory grouping that uses the terms type Ia and type Ib, type II, typ…Wikipedia · Text under CC-BY-SA license- Estimated Reading Time: 5 mins

It is suggested that when grouping fibres by their conduction velocities the original terminology introduced by Erlanger and Gasser41 (i.e. A-alpha, beta, gamma, delta, B and C) should be used for efferent nerve fibres, while the …
- This review provides an historical perspective to the present system of classification of nerve fibres and makes suggestions for a more uniform method of description in the future. The composition of nerves was first studied by Remak' and subsequently by Sherrington' who observed that muscle nerves contained larger afferent fibres than cutaneous ne...
