Overproduction
Most species produce more offspring than can survive.
Competition
Since living space and food are limited, organisms must compete for the necessities.
Variation
Differences between individuals in a population.
Adaptations
Any kind of inherited trait that improves an organism's chances of survival.
Natural selection
The environment selects organisms with optimal traits to be the parents of the next generation.
Speciation
Over many generations, favorable adaptations accumulate and may result in a new species.
examples of vestigial structure would include the tail bone, wisdom teeth, and the appendix. hope this helps :)
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.
