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 ...
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 ...
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 ...

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 ...
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 ...
Purpose. used to study the facial nerve (Bell's palsy) Electroneuronography or electroneurography (ENoG) is a neurological non-invasive test used to study the facial nerve in cases of muscle weakness in one side of the face (Bell's palsy). The technique of electroneuronography was first used by Esslen and Fisch in 1979 to describe a technique ...
Yo-yo: a game of "back and forth," which can mean that the horse backs away from the human and returns. Another type of yo-yo game involves the horse speeding up or slowing down. Circling: often compared to longeing the horse, although Parelli asserts that the two are distinctly different. In the Circling Game, it is the horse's responsibility ...
