Vulva The term vulva, or pudendum , refers to the external genitalia of the female (Figure 28.20). It consists of the mons pubs, labia majora, labia minora, clitoris, vestibule, vaginal and urethral orifices, hymen, bulb of the vestibule, and the paraurethral (Skene’s), greater vestibular (Bartholin’s), and lesser vestibular glands (Figure 28.21). Table 28.2 summarizes the homologous structures of the male and female reproductive systems.

Mammary Glands The mammary glands are modified sudoriferous (sweat) glands that lie over the pectoralis major and serratus anterior muscles (Figure 28.22). Milk-secreting cells, referred to as alveoli, are clustered in small compartments (lobules) within the breasts. The essential functions of the mammary glands are synthesis of milk, secretion and ejection of milk, which constitute lactation.
