How Do You Spell WALLERIAN DEGENERATION?

Pronunciation: [wɒlˈi͡əɹɪən dɪd͡ʒˌɛnəɹˈe͡ɪʃən] (IPA)

Wallerian degeneration (wɔːlɪərɪən dɪˌɡɛnəˈreɪʃən) is a medical term that describes the degeneration or breakdown of nerve fibers in the peripheral nervous system. The word 'Wallerian' is named after the English neuroanatomist Augustus Waller, who first discovered this phenomenon in 1850. The phonetic transcription of the word shows that it is pronounced with emphasis on the first syllable 'wɔːlɪərɪən', followed by the stress on the second syllable 'dɪˌɡɛnəˈreɪʃən'. Understanding the spelling and pronunciation of medical terms is essential for healthcare professionals to communicate effectively with colleagues and patients.

WALLERIAN DEGENERATION Meaning and Definition

1. Wallerian degeneration is a physiological process that involves the degeneration and breakdown of nerve fibers or axons after they have been injured or severed. It is named after the British neurophysiologist Augustus Waller, who first described this phenomenon.

   When a nerve fiber is injured or cut, Wallerian degeneration is triggered as part of the body's natural response to protect and repair damaged nerve tissue. The process involves a series of events that occur in sequential stages. Initially, the axon distal to the injury site undergoes an acute response, which includes swelling and disconnection from the neuron's cell body. This is followed by the degeneration of the axon, including the breakdown of its myelin sheath.

   As Wallerian degeneration progresses, specialized cells called macrophages invade the site and remove the remnants of the degenerated axon. At the same time, the injured neuron attempts to regenerate by sending out new sprouts from the proximal stump. These sprouts may grow and attempt to reconnect with their original targets, or they may form inappropriate connections called "neuroma."

   The speed and success of axonal regeneration during Wallerian degeneration depend on various factors, such as the type and severity of the injury, the location in the nervous system, and the age and overall health of the individual.

   In summary, Wallerian degeneration is a process where nerve fibers undergo a series of degenerative changes after getting injured or severed. This phenomenon is an essential part of the body's attempt to repair damaged nerve tissue.
