Vasocongestion |
-Erection -blood flow into vessels in region of genitals |
|
Myotonia |
muscle contraction in genitals and throughout body -female ogasm |
|
Excitement (Male) |
-beginning of arousal -vasocongestion -testes closer to body -LATE: enlarged prostate/pre-cum/larger coronal ridge/thick scrotum/elevated testes |
|
Orgasm (male) |
seminal vesicles contract vas def contracts sperm combines with fluids urethra contracts to force sperm out |
|
Resolution (male)
|
everything reverses -testes descend/scrotm thins/erection disappears -refractory period: can't be rearoused and have another orgasm right away |
|
Excitement (women) |
-vasocongestion: vaginal lube/large clit/labia swell/uterus elevates -vagina walls expand (upper 2/3) -LATE: uterus higher/more vag expansion/ walls thicken with orgasm/clit retracts
|
|
Orgasm (woman) |
-myotonia response -rhythmic contractions at vaginal opening |
|
Resolution (women) |
Everything reveres that was enlarged or elevated -platform disappears -no refractory period -- multiple orgasms |
|
orgasmic platform |
tightening of the bulbospongiosus muscle at vaginal opening -opening becomes smaller --> grips penis |
|
Breast Response |
-erect nipple -size slightly increases -all reversed in resolution |
|
Extragenital Responses |
Excitement --> nipple erect/sex flush Orgasm --> carpopedal spasm/increased BP/HR resolution-->sweating/hyperventilation |
|
Penile Smooth Muscle Relaxation |
-NO neurotransmitter NO--> cGMP-->muscle relaxation PDE5 degrades cGMP --> no erection viagara inhibits PDE5 |
|
Spinal Reflex -- erection |
stimulated by sensory neurons -sacral neurons go to penis and relax it for the blood to flow |
|
Master's and Johnson |
-Model of Excite/Orgasm/resolution -ignores cognition and emotion -sampling was not random -results only with top 50% of population |
|
Kaplan Model |
Triphasic Model -sexual desire -vasocongestion (parasympathetic) -myotonia (sympathetic) -either desire-->excitement or vice versa |
|
Dual Control Model |
-Sexual Excitation- Inhibition Model -2 basic processes needs to be a balance of the 2 otherwise could have risky behavior or a disorder |
|
Emotion and arousal |
missing from all studies -one study showed: positive emotions --> strong sexual arousal thoughts/negative emotions --> also more sex thoughts |
|
G Spot |
-Grafenberg Spot -skene's gland(female prostate) --> top side of vag between pubic bone and cervix -responsible for female ejaculation -uterine orgasm after feeling need to pee -controversial |
|
Phermones |
-biochemicals secreted out of body that serve as sex attractants -been tested on animals - menstrual synchrony: getting period at same time - McClintock Experiement -pads before ovulation-->early LH surge - pads late luteal --> late LH surge |
|
Activating effects |
activate sexual desires,behaviors -humans are less influences than other species
|
|
Testosterone effects |
-Males-effects desire, Testos surge at puberty -females-- from ovarian and adrenal androgens, effects desire -adrenalectomies decrease sex drive |
