The pubococcygeus muscle controls urine flow and contracts during orgasm as well as assisting in male ejaculation. [6] It also aids in childbirth as well as core stability. [7] A strong pubococcygeus muscle has also been linked to a reduction in urinary incontinence and proper positioning of the baby's head during childbirth.
Reproducing this type of muscle action can strengthen the Kegel muscles. The action of slowing or stopping the flow of urine may be used as a test of the correct pelvic-floor exercise technique. [11] [12] The components of levator ani (the pelvic diaphragm), namely pubococcygeus, puborectalis and iliococcygeus, contract and relax as one muscle ...
Torticollis is a fixed or dynamic tilt, rotation, with flexion or extension of the head and/or neck. The type of torticollis can be described depending on the positions of the head and neck. [1] [3] [4] laterocollis: the head is tipped toward the shoulder; rotational torticollis: the head rotates along the longitudinal axis towards the shoulder [5]
A survey of 59 patients diagnosed with spasmodic torticollis show that 43% of the patients visited at least four physicians before the diagnosis was made. [31] There is a higher prevalence of spasmodic torticollis in females; females are 1.5 times more likely to develop spasmodic torticollis than males.
The coccygeus muscle is posterior to levator ani and anterior to the sacrospinous ligament in the pelvic floor.It is a triangular plane of muscular and tendinous fibers. It arises by its apex from the spine of the ischium and sacrospinous ligament.
[7] [8] [9] Other muscles that are part of the levator ani are: the pubococcygeus muscle which is made up of the puboperineal, pubovaginal, and puboanal muscles; the puborectal muscle; and the iliococcygeal muscle. [9] [10] The pubovaginal muscle was identified by anatomists as early as 1912. [11]
These masculinity norms exert a toll on everyone, even their perpetrators. Feminine gay men are at higher risk of suicide, loneliness and mental illness. Masculine gay men, for their part, are more anxious, have more risky sex and use drugs and tobacco with greater frequency. One study investigating why living in the gay community increases ...
Paradoxical anal contraction during attempted defecation in constipated patients was first described in a paper in 1985, when the term anismus was first used. [40] The researchers drew analogies to a condition called vaginismus, which involves paroxysmal (sudden and short lasting) contraction of pubococcygeus (another muscle of the pelvic floor ...
