axonal degeneration

an axon dies and cannot be replaced if its cell body is destroyed. A damaged axon in the central nervous system similarly cannot undergo regeneration, but a peripheral nerve with an intact nerve cell can regenerate. See also wallerian degeneration.

axonal dystrophy

specific diseases characterized by nutritional abnormalities of axons include in sheep, Suffolk, Coopworth, Merino axonal dystrophies, in dogs, Rottweiler, Chiahuahua dystrophies, in horses Haflinger, Morgan, in cats a dystrophy in lilac coat color domestic shorthaired.

giant axonal neuropathy

see giant axonal neuropathy.

axonal migration

the movement of axoplasm from the proximal segment of a severed nerve fiber to the distal portion, following Schwann cell extensions, in the process of peripheral nerve regeneration.

axonal reaction

central chromatolysis of the axon characterized by eccentric relocation of the nucleus, greater prominence of the nucleolus and a basophilic cap of RNA on its cytoplasmic aspect, dispersal of the Nissl substance to the periphery of the cell, and an increase in the number of neurofilaments.
