Components
(generated)
Component items:
- Genitalia - sensations (genitalia-sensory)
- Genitalia - utetovaginal visceral receptors (utetovaginal-visceral-receptors -> LPC.PN.SG.LDRG): sexual sensations
- Genitalia - visceral sexual receptors (visceral-sexual-receptors -> LPC.PN.SG.LDRG): sexual sensations
- Genitalia - urination and support muscles (genitalia-urination)
- Genitalia - bulbospongiosus muscle (LPC.SC.VH.ONF -> bulbospongiosus-muscle): in males, empties the urethra; in females, clenches the vagina
- Genitalia - pubococcygeus muscle (LPC.SC.VH.VM -> pubococcygeus-muscle): controls urine flow and contracts during orgasm
- Genitalia - erection muscles (genitalia-erection)
- Genitalia - ischiocavernosus muscle (LPC.SC.VH.ONF -> ischiocavernosus-muscle): stabilize the erect penis or (in females) tense the vagina during orgasm
- Genitalia - man erection muscles (genitalia-erection-man)
- Genitalia - corpus cavernosum penis (LAC.PN.PSYM.PPG -> corpus-cavernosum-penis): penile erection; simultaneously the ischiocavernosus and bulbospongiosus muscles compress the veins of the corpora cavernosa restricting the egress and circulation of this blood
- Genitalia - woman erection muscles (genitalia-erection-woman)
- Genitalia - uterus, sympathetic contractors (LAC.PN.SYM.IMG -> uterus-sympathetic): contraction of smooth muscles of myometrium, decreased blood flow, loss of erection
- Genitalia - parasympathetic uterus vasodilators (LAC.PN.PSYM.PPG -> uterus-parasympathetic): female - contraction of smooth muscles of myometrium, increased blood flow; sexual response by directing blood flow to the pelvis and to the external genitalia, including the ovaries, vagina, labia, and clitoris
- Genitalia - vagina, sympathetic vasoconstrictors (LAC.PN.SYM.IMG -> vagina-sympathetic): vasoconstriction of fibromuscular tube, loss of erection
- Genitalia - parasympathetic vaginal vasodilators (LAC.PN.PSYM.PPG -> vagina-parasympathetic): female - contraction of smooth muscles of myometrium, increased blood flow
- Genitalia - corpus cavernosum clitoridis (LAC.PN.PSYM.PPG -> corpus-cavernosum-clitoridis): clitoral erection; simultaneously the ischiocavernosus and bulbospongiosus muscles compress the veins of the corpora cavernosa restricting the egress and circulation of this blood
- Genitalia - ejaculation muscles and glands, pregnancy and lifecycle support (genitalia-ejaculation)
- Genitalia - man ejaculation muscles and glands (genitalia-ejaculation-man)
- Genitalia - cowper gland (LAC.PN.SYM.IMG -> cowper-gland): produces a clear, salty, viscous secretion known as pre-ejaculate, homologous to Bartholin glands in females
- Genitalia - prostate gland (LAC.PN.SYM.IMG -> prostate-gland): secrete a slightly alkaline fluid, milky or white in appearance, constitutes 50-75 percents of the volume of the semen along with spermatozoa and seminal vesicle fluid
- Genitalia - vas deferens (LAC.PN.SYM.IMG -> vas-deferens): male - emission (prior to ejaculation), contracts, propelling sperm forward
- Genitalia - deep transverse perineal muscle, penis (LPC.SC.VH.ONF -> deep-transverse-perineal-muscle-penis): fixation of central tendon of perineum, support of pelvic floor, expulsion of semen in males and last drops of urine in both sexes
- Genitalia - woman ejaculation muscles and glands (genitalia-ejaculation-woman)
- Genitalia - bartholin gland (LAC.PN.SYM.IMG -> bartholin-gland): secretes mucus to lubricate the vagina
- Genitalia - skenes gland (LAC.PN.SYM.IMG -> skenes-gland): cause female ejaculation and G-Spot orgasms
- Genitalia - cervix (LAC.PN.SYM.IMG -> cervix-gland): female - produces cervical mucus that changes in consistency during the menstrual cycle to prevent or promote pregnancy
- Genitalia - deep transverse perineal muscle, clitoris (LPC.SC.VH.ONF -> deep-transverse-perineal-muscle-clitoris): fixation of central tendon of perineum, support of pelvic floor and last drops of urine in both sexes
- Genitalia - man ejaculation muscles and glands (genitalia-ejaculation-man)
- Genitalia - scrotum muscles (genitalia-scrotum-muscles)
- Genitalia - cremaster muscle (LAC.PN.SYM.IMG -> cremaster-muscle): raise and lower the scrotum, acts quickly, it is a reflex
- Genitalia - dartos muscle (LAC.PN.SYM.IMG -> dartos-muscle): corrugates the scrotum; contraction reduces the surface area available for heat loss, thus reducing heat loss and warming the testicles; expansion increases the surface area, promoting heat loss and thus cooling the testicles.
