Ejaculation – Wikidoc
Ejaculation has two phases: emission and ejaculation correct. The emission part of the ejaculatory reflex is under control of the sympathetic nervous system, whereas the ejaculatory part is below management of a spinal reflex at the level of the spinal nerves S2-four through the pudendal nerve. During emission, the two ducts often known as vas deferens contract to propel sperm from the epididymis where it was saved as much as the ampullae at the top finish of the vas deferens. The start of emission is often skilled as a “point of no return,” also called point of ejaculatory inevitability. The sperm then passes by the ejaculatory ducts and is mixed with fluids from the seminal vesicles, the prostate, and the bulbourethral glands to type the semen, or ejaculate. Throughout ejaculation proper, the semen is ejected by means of the urethra with rhythmic contractions.[1]
During heterosexual intercourse, the vagina offers sexual stimulation to the penis, typically leading to orgasm and ejaculation. Usually, ejaculation is required for emission of sperm; if ejaculation happens whereas the penis is either near or throughout the girl’s vagina, sperm can then fertilize a girl’s egg and impregnate her. Nevertheless, almost all men produce a small quantity of pre-ejaculate fluid when their penis is erect and they’re sexually stimulated, and this pre-ejaculate could comprise some sperm which may also result in pregnancy. For this reason, coitus interruptus may still result in undesirable pregnancies for couples partaking in vaginal intercourse if different forms of start management should not used as properly.
Sadly, it’s tough to get rid of false-positive test outcomes. For instance, a mammogram may accurately present abnormal cells in the breast ducts that might turn out to be cancerous, when in actuality they aren’t life-threatening and will not trigger symptoms [source: National Most cancers Institute]. Patients screening for ovarian cancer may be given a most cancers antigen 125 blood check (CA-125). If a lady’s CA-125 level is elevated, most cancers is suspected and extra testing could end result. The problem is, a whole lot of different situations could cause an elevated CA-125 stage, comparable to diverticulitis, pregnancy and even regular menstruation, so the check isn’t really useful for women with only an average danger of ovarian most cancers [supply: Laughlin-Tommaso].
Wind Damp: Arthritis is a manifestation of this sample. Like dampness in nature, which is persistent and requires time to eradicate, the dampness pathogenic influence is troublesome to cure and takes some time to resolve. The affect of wind also causes the pain to migrate from joint to joint, sometimes disappearing for some time only to reappear with out warning. Therapy for this syndrome includes herbs that drain dampness and improve circulation of qi and blood via the affected areas. Moxibustion therapy — the applying of heat — is especially useful in this example.
Spina bifida: Spina bifida is a failure in the closure of the bony vertebral column with or with out protrusion of the nerve tissue of the spinal cord. Paralysis below the defect often accompanies spina bifida if the spinal cord does protrude. When the spinal cord does not protrude, the vertebral defect may go unnoticed. Clues to indicate the presence of this type of spina bifida are abnormalities of the pores and skin and سكس انطونيو tufts of hair overlying the spine within the lower a part of the back.
