Anatomy and Physiology of the Male Sexual Response
5 important questions on Anatomy and Physiology of the Male Sexual Response
What is the Seminal vesicle?
- Lies on the posterior wall of the bladder
- Secretes 70% of the volume of semen
- Seminal fluid: Fructose, Fibronigen & Prostaglandins
What does the 3 seminal fluids from the Seminal Vesicle do?
- Fibronigen: Help turn semen into a bolus that can easy propelled into vagina.
- Prostaglandins: Decrease cervical mucus viscosity and stimulate reverse peristalsis of the uterus
What does the Bulbourethral gland?
- inferior to the prostate
- produces alkaline mucus:
- neutralizes traces of acidic urine in the urethra
- help lubricate the urethra and the head of the penis
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What is the Sexual response cycle of the human male?
What happens in the Arousal stage?
- Erotic thoughts
- physical stimulation causes parasympathetic reflex that cause erection.
- Release of: NO, dopamine, serotonine, oxytocine
- cognitive factors (visual stimuli, activity in amygdala &hypothalamus) contribute to sexual arousal and sexual response in males.
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
