PSY354H5 Chapter Notes - Chapter 4: External Anal Sphincter, Pubic Hair, Urethra
Document Summary
The male external genitalia are the penis and scrotum. The parts of the male reproductive system that can been seen from the outside are the penis and the scrotum. The testicles, or balls , are indirectly visible as the twin bulges that give the scrotum its shape. Men have similar distribution of pubic hair as seen in women: the hair may extend upward in the midline toward the navel or merge with the general body hair. The penis combines erotic, reproductive, and excretory functions. Penis: the erectile, erotically sensitive genital organ in males. The penis is involved in sexual arousal, excretion of urine, and the transfer of gametes from the male to the female. The penis in its natural (i. e. , uncircumcised) condition has three visible portions: a shaft, a head (or glands), and a foreskin. Foreskin: the loose skin that partially or completely covers the glans in males who have not been circumcised.
