Wallerian degeneration is an active process of degeneration that results when a nerve fiber is cut or crushed and the part of the axon distal to the injury (which in most cases is farther from the neuron 's cell body) degenerates. [ 1 ] A related process of dying back or retrograde degeneration known as 'Wallerian-like degeneration' occurs in ...
Horse behavior. Free-roaming mustangs (Utah, 2005) Horse behavior is best understood from the view that horses are prey animals with a well-developed fight-or-flight response. Their first reaction to a threat is often to flee, although sometimes they stand their ground and defend themselves or their offspring in cases where flight is untenable ...
Neurapraxia. Specialty. Neurology. Neurapraxia is a disorder of the peripheral nervous system in which there is a temporary loss of motor and sensory function due to blockage of nerve conduction, usually lasting an average of six to eight weeks before full recovery. Neurapraxia is derived from the word apraxia, meaning “loss or impairment of ...

The Henneke horse body condition scoring system is a numerical scale used to evaluate the amount of fat on a horse's body. It was developed in the early 1980s by Don Henneke at Texas A&M University with the goal of creating a universal scale to assess horses' bodyweight, [ 1 ] and was first published in 1983. [ 2 ]
Another possible effect of Bell's palsy is Wallerian degeneration (WD), which may take days to become evident. Because of the slow-acting nature of this pathology, a patient may present healthy electroneuronography results despite a lack of volitional control of the facial muscles immediately following the onset of Bell's palsy.
When the axon is torn, Wallerian degeneration, in which the part of the axon distal to the break degrades, takes place within one to two days after injury. [26] The axolemma disintegrates, [ 26 ] myelin breaks down and begins to detach from the cell in an anterograde direction (from the body of the cell toward the end of the axon), [ 27 ] and ...
Equine-assisted psychotherapy (EAP) does not necessarily involve riding, but may include grooming, feeding and ground exercises. Mental health professionals work with one or more clients and one or more horses in an experiential manner to help the clients learn about themselves and others, while processing or discussing the client's feelings ...
