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*)

* [- bulbospongiosus muscle] (BrainRegionLPC_SC_VH_ONF LPC.SC.VH.ONF -> HumanMusclesTorso bulbospongiosus-muscle): in males, empties the urethra; in females, clenches the vagina
* [- pubococcygeus muscle] (BrainRegionLPC_SC_VH_VM LPC.SC.VH.VM -> HumanMusclesTorso pubococcygeus-muscle): controls urine flow and contracts during orgasm

• *Genitalia - erection muscles* (*genitalia-erection*)

* [- ischiocavernosus muscle] (BrainRegionLPC_SC_VH_ONF LPC.SC.VH.ONF -> HumanMusclesTorso ischiocavernosus-muscle): stabilize the erect penis or (in females) tense the vagina during orgasm
* *Genitalia - man erection muscles* (*genitalia-erection-man*)
 * [- corpus cavernosum penis] (BrainRegionLAC_PN_PSYM_PPG LAC.PN.PSYM.PPG -> HumanMusclesTorso 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*)
 * [- uterus, sympathetic contractors] (BrainRegionLAC_PN_SYM_IMG LAC.PN.SYM.IMG -> HumanMusclesTorso uterus-sympathetic): contraction of smooth muscles of myometrium, decreased blood flow, loss of erection
 * [- parasympathetic uterus vasodilators] (BrainRegionLAC_PN_PSYM_PPG LAC.PN.PSYM.PPG -> HumanMusclesTorso 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
 * [- vagina, sympathetic vasoconstrictors] (BrainRegionLAC_PN_SYM_IMG LAC.PN.SYM.IMG -> HumanMusclesTorso vagina-sympathetic): vasoconstriction of fibromuscular tube, loss of erection
 * [- parasympathetic vaginal vasodilators] (BrainRegionLAC_PN_PSYM_PPG LAC.PN.PSYM.PPG -> HumanMusclesTorso vagina-parasympathetic): female - contraction of smooth muscles of myometrium, increased blood flow
 * [- corpus cavernosum clitoridis] (BrainRegionLAC_PN_PSYM_PPG LAC.PN.PSYM.PPG -> HumanMusclesTorso 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*)
 * [- cowper gland] (BrainRegionLAC_PN_SYM_IMG LAC.PN.SYM.IMG -> HumanMusclesTorso cowper-gland): produces a clear, salty, viscous secretion known as pre-ejaculate, homologous to Bartholin glands in females
 * [- prostate gland] (BrainRegionLAC_PN_SYM_IMG LAC.PN.SYM.IMG -> HumanMusclesTorso 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
 * [- vas deferens] (BrainRegionLAC_PN_SYM_IMG LAC.PN.SYM.IMG -> HumanMusclesTorso vas-deferens): male - emission (prior to ejaculation), contracts, propelling sperm forward
 * [- deep transverse perineal muscle, penis] (BrainRegionLPC_SC_VH_ONF LPC.SC.VH.ONF -> HumanMusclesTorso 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*)
 * [- bartholin gland] (BrainRegionLAC_PN_SYM_IMG LAC.PN.SYM.IMG -> HumanMusclesTorso bartholin-gland): secretes mucus to lubricate the vagina
 * [- skenes gland] (BrainRegionLAC_PN_SYM_IMG LAC.PN.SYM.IMG -> HumanMusclesTorso skenes-gland): cause female ejaculation and G-Spot orgasms
 * [- cervix] (BrainRegionLAC_PN_SYM_IMG LAC.PN.SYM.IMG -> HumanMusclesTorso cervix-gland): female - produces cervical mucus that changes in consistency during the menstrual cycle to prevent or promote pregnancy
 * [- deep transverse perineal muscle, clitoris] (BrainRegionLPC_SC_VH_ONF LPC.SC.VH.ONF -> HumanMusclesTorso deep-transverse-perineal-muscle-clitoris): fixation of central tendon of perineum, support of pelvic floor and last drops of urine in both sexes

• *Genitalia - scrotum muscles* (*genitalia-scrotum-muscles*)

* [- cremaster muscle] (BrainRegionLAC_PN_SYM_IMG LAC.PN.SYM.IMG -> HumanMusclesTorso cremaster-muscle): raise and lower the scrotum, acts quickly, it is a reflex
* [- dartos muscle] (BrainRegionLAC_PN_SYM_IMG LAC.PN.SYM.IMG -> HumanMusclesTorso 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.
