Name the three parts of the penis that are involved in sexual arousal, excretion of urine, and transfer of sperm.

Penis, Foreskin (Prepuce), Urethra & Urethral Opening

What are the two erectile structures located within the shaft of the penis?

Cavernous Bodies (Corpora Cavernosa)

Where is the PC (Pubococcygeus) muscle located in the male anatomy?

Near the midline of the penis, on its lower surface, extends from the shaft into the glans

What is the function of the scrotum in the male anatomy?

To house and protect the testes, maintaining their temperature slightly lower than the rest of the body Signup and view all the answers

What is the function of the glans (head) of the penis?

The glans is sensitive and plays a key role in sexual pleasure and reproduction, as it contains a high concentration of nerve endings and is involved in the release of semen during ejaculation Signup and view all the answers

Where are the cavernous bodies (corpora cavernosa) located within the shaft of the penis?

The cavernous bodies (corpora cavernosa) are two erectile structures that lie side by side along the upper side of the penis, located within the shaft of the penis. Signup and view all the answers

What is the function of the PC (Pubococcygeus) muscle in the male anatomy?

The PC (Pubococcygeus) muscle underlies and supports pelvic organs, near the midline of the penis, on its lower surface, and extends from the shaft into the glans. Signup and view all the answers

Describe the location and function of the scrotum in the male anatomy.

Study Notes

Penis Structure and Function

The three parts of the penis involved in sexual arousal, excretion of urine, and transfer of sperm are the root, shaft, and glans.

Erectile Structures

The two erectile structures within the shaft of the penis are the corpora cavernosa and the corpus spongiosum.

PC Muscle

The PC (Pubococcygeus) muscle is located in the pelvic floor.
The function of the PC muscle is to control the flow of semen and urine during ejaculation.

Scrotum

The scrotum is located in the male anatomy below the penis.
The function of the scrotum is to regulate the temperature of the testes and protect them from injury.

Glans and Frenulum

The function of the glans (head) of the penis is to provide sensation and facilitate sexual arousal.
The frenulum is a thin band of tissue located on the underside of the glans, connecting it to the shaft.
The function of the frenulum is to provide sensation and facilitate sexual arousal.

Corpora Cavernosa

The cavernous bodies (corpora cavernosa) are located within the shaft of the penis.
The corpora cavernosa are responsible for filling with blood during sexual arousal, leading to erection.
