HUMAN DISEASE
Detrusor sphincter dyssynergia; Neurogenic detrusor overactivity
Bladder sphincter dyssynergia (also known as detrusor sphincter dyssynergia (DSD) (the ICS standard terminology agreed 1998) and neurogenic detrusor overactivity (NDO)) is a consequence of a neurological pathology such as spinal injury or multiple sclerosis Urination disorders occur in 80% patients with multiple sclerosis (MS). The most common of them is detrusor-sphincter dyssynergia (DSD), which disrupts central nervous system regulation of the micturition (urination) reflex resulting in dyscoordination of the detrusor muscles of the bladder and the male or female external urethral sphincter muscles.
Ramsay Hunt syndrome type 1
DEGENERATIVE, NEUROLOGICAL DISORDER CHARACTERIZED BY MYOCLONUS EPILEPSY, INTENTION TREMOR, PROGRESSIVE ATAXIA AND OCCASIONALLY COGNITIVE IMPAIRMENT
Ramsay Hunt cerebellar syndrome; Dentatorubral degeneration; Ramsay Hunt syndrome type I
Ramsay Hunt syndrome type 1 is a rare, degenerative, neurological disorder characterized by myoclonus epilepsy, intention tremor, progressive ataxia and occasionally cognitive impairment

FAILURE OF THE NORMAL RELAXATION OF PELVIC FLOOR MUSCLES DURING ATTEMPTED DEFECATION
Spastic pelvic floor syndrome; Anal sphincter dyssynergia; Paradoxical puborectal contraction; Dyssynergic defecation
Anismus or dyssynergic defecation is the failure of normal relaxation of pelvic floor muscles during attempted defecation. It can occur in both children and adults, and in both men and women (although it is more common in women).

Cerebellar peduncle
Cerebellar peduncles connect the cerebellum to the brain stem. There are six cerebellar peduncles in total, three on each side:
- Superior cerebellar peduncle is a paired structure of white matter that connects the cerebellum to the mid-brain.
- Middle cerebellar peduncles connect the cerebellum to the pons and are composed entirely of centripetal fibers.
- Inferior cerebellar peduncle is a thick rope-like strand that occupies the upper part of the posterior district of the medulla oblongata.
The peduncles form the lateral border of the fourth ventricle, and form a distinctive diamond – the middle peduncle forming the central corners of the diamond, while the superior and inferior peduncles form the superior and inferior edges, respectively.
