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*) * [http://en.wikipedia.org/wiki/Bulbourethral_gland Genitalia - 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 * [http://en.wikipedia.org/wiki/Prostate Genitalia - 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 * [http://en.wikipedia.org/wiki/Prostate Genitalia - vas deferens] ([BrainRegionLAC_PN_SYM_IMG LAC.PN.SYM.IMG] -> [HumanMusclesTorso vas-deferens]): male - emission (prior to ejaculation), contracts, propelling sperm forward * [http://en.wikipedia.org/wiki/Transversus_perinei_profundus_muscle Genitalia - 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*) * [http://en.wikipedia.org/wiki/Bartholin%27s_gland Genitalia - bartholin gland] ([BrainRegionLAC_PN_SYM_IMG LAC.PN.SYM.IMG] -> [HumanMusclesTorso bartholin-gland]): secretes mucus to lubricate the vagina * [http://en.wikipedia.org/wiki/Skene%27s_gland Genitalia - skenes gland] ([BrainRegionLAC_PN_SYM_IMG LAC.PN.SYM.IMG] -> [HumanMusclesTorso skenes-gland]): cause female ejaculation and G-Spot orgasms * [http://en.wikipedia.org/wiki/Cervix Genitalia - 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 * [http://en.wikipedia.org/wiki/Transversus_perinei_profundus_muscle Genitalia - 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*) * [http://en.wikipedia.org/wiki/Cremaster_muscle Genitalia - cremaster muscle] ([BrainRegionLAC_PN_SYM_IMG LAC.PN.SYM.IMG] -> [HumanMusclesTorso cremaster-muscle]): raise and lower the scrotum, acts quickly, it is a reflex * [http://en.wikipedia.org/wiki/Dartos Genitalia - 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. = Connectivity = (generated) http://ahuman.org/svn/ahwiki/images/dot/TARGET.TEA.GENITALIA.dot.png *Inbound Region Connections:* || *Source Area* || *Source Region* || *Source Name* || *Type* || *Role* || *Reference* || || [BrainAreaLAC LAC] || [BrainRegionLAC_PN_PSYM_PPG LAC.PN.PSYM.PPG] || Pelvic Peripheral Ganglion || corpus-cavernosum-clitoridis || (none) ||(unknown reference) || || || [BrainRegionLAC_PN_SYM_IMG LAC.PN.SYM.IMG] || Inferior Mesenteric Ganglion || bartholin-gland || (none) ||(unknown reference) || || [BrainAreaLPC LPC] || [BrainRegionLPC_SC_VH_ONF LPC.SC.VH.ONF] || Onuf's Nucleus || bulbospongiosus-muscle || (none) ||(unknown reference) || || || [BrainRegionLPC_SC_VH_VM LPC.SC.VH.VM] || Ventromedial Nucleus || pubococcygeus-muscle || (none) ||(unknown reference) || *Outbound Region Connections:* || *Target Area* || *Target Region* || *Target Name* || *Type* || *Role* || *Reference* || || [BrainAreaLPC LPC] || [BrainRegionLPC_PN_SG_LDRG LPC.PN.SG.LDRG] || Lower Dorsal Root Ganglion || utetovaginal-visceral-receptors || (none) || (unknown reference) || = Thirdparty Circuits = (generated) * no circuits defined = References = (generated) * no references defined
