physiology of in male-3D male Body and Biology

S e x u a l desire or attraction is triggered by various stimuli, such as visual, auditory, emotional, tactile (touch), fantasies, thoughts, or memory cues. When these stimuli are received, the body begins to respond and cause physiological changes in the body. In response to the stimuli, the brain releases neurotransmitters like dopamine and nitric oxide. These chemicals act as messengers that help to dilate the blood vessels in the pelvic region, including those in the penis. The dilation of blood vessels allows more blood to flow into the penile tissues. The penis has three cylindrical chambers made up of a sponge-like material. When these chambers fill with blood, the penis becomes rigid and erect. At this stage, the male body is prepared for sexual activity. Nerve endings become more sensitive, and touch or friction is met with heightened sensation. To maintain the erection, the veins that usually allow blood to flow out of the penis become compressed. This helps to keep the blood in the penile chambers, sustaining the erection. As s e x u a l activity or stimulation continues, tension builds within the pelvic region. 3dmedicalanimation copyrighted_by_Dandelion _Team The Female Body and Biology | Biology of Female Hemorrhoids|different types of hemorrhoids Virginity and hymen Fertilization medical animation we all won this race!
