The sperm has an oval head that contains its genetic matter, and sphincter A muscle that surrounds and, by its it is propelled by a flagellating tail. A sperm is car- contraction, closes a normal opening such as that ried into the female reproductive tract within the from the intestinal tract or the urinary tract. If the sperm is able to travel up to the anal and urethral sphincters can cause fecal into a fallopian tube, it must then break through the and urinary incontinence, respectively. Sphincters cell wall of the egg (the female gamete, or ovum) to tend to be ring-like and, when contracted, to con- fertilize the egg and form a zygote. People with spina bifida often have neurological deficits below the level of the sphygmomanometer Blood pressure cuff, an lesion and can suffer from bladder and bowel instrument for measuring blood pressure, particu- incontinence, limited mobility (due to paralysis of larly in arteries. The two basic types of manual sphygmo- bifida varies according to country, ethnic group, manometers are the mercury column and the gauge and socioeconomic status. The manual sphygmomanometer in spina bifida occurs in 1 in every 1,000 to 2,000 most frequent use today consists of a gauge attached births. The risk of spina bifida and other neural to a rubber cuff that is wrapped around the upper tube defects, such as anencephaly, can be signifi- arm and is inflated to constrict the arteries. A blood cantly decreased if women take ample folic acid pressure reading consists of two numbers: systolic before conception and during pregnancy. Systolic refers to systole, the phase when the heart pumps blood out into the aorta. Diastolic refers to diastole, the resting period when the heart refills with blood. At each heartbeat, the spina bifida occulta A bony defect in the verte- blood pressure is raised to the systolic level, and, bral column that causes a cleft in that column. Treatment is usually cuff inflated with air, a stethoscope is placed over an not required. As the air in the cuff is released, the pressure reading spinal column See vertebral column. As the release of air from spinal cord The major column of nerve tissue the cuff continues, a point is reached when the sound that is connected to the brain and lies within the ver- diminishes and then is no longer heard. The pressure tebral canal and from which the spinal nerves at which the last sound is heard marks the diastolic emerge. The blood pressure reading might show the in the spinal cord: 8 cervical, 12 thoracic, 5 lumbar, systolic and diastolic pressures to be, for example, 5 sacral, and 1 coccygeal. Children and adults with smaller- spinal cord is covered by three connective-tissue or larger-than-average-sized arms may need special- envelopes called the meninges.
