Explanation:
Nondisjunction: Failure of paired chromosomes to separate (to disjoin) during cell division, so that both chromosomes go to one daughter cell and none go to the other. Nondisjunction causes errors in chromosome number, such as trisomy 21 (Down syndrome) and monosomy X (Turner syndrome). It is also a common cause of early spontaneous abortions

One of the many tests done during urodynamic studies is the sphincter electromyelogram. This test studies activity of the voluntary muscles of the perineal area.
- Patients with urine incontinence or other symptoms of the lower urinary tract can be diagnosed with urodynamic testing.
- Both men and women take these examinations. Nerve and muscle function are measured by urodynamic testing.
- Clinically, perineal sphincter electromyography may be helpful in assessing individuals with bowel, urinary, and sexual dysfunction.
- All patients with a history and clinical examination that point to a central or peripheral sacral neuropathic lesion should be given this option.
- The pudendal nerve innervates the external sphincter (EAS), which is the best muscle for identifying neuropathic lesions in lower sacral myotomes.
