For women, it is not only an aspect of female fitness, but also a sexual sensitive area. When men touch breasts, it can arouse women's sexual desire and stimulate breast growth. The breasts and nipples are rich in nerve endings, and stimulation of female breasts can produce sexual excitement. For men, women's breasts have an eternal allure. In systemic anatomy, the breasts belong to the female reproductive system. A woman's breasts are located on the pectoralis major muscle, usually extending from the second rib to the sixth rib, medially to the parasternal line, and laterally to the mid-axillary line. The mammary gland (mamma; breast) is a structure unique to mammals. Females begin to develop and grow after puberty, and their breasts have secretory activity during pregnancy and lactation. Breasts are secondary sexual organs, and female breasts are also lactation organs. The breast is mainly composed of connective tissue, adipose tissue, mammary gland, a large number of blood vessels and nerves. The position of the breasts changes as you age. The breasts of adult women are located in the superficial fascia over the pectoralis major muscle, with the upper and lower edges flush with the 2nd and 6th ribs respectively. The following is an overview of the major tissues that make up the breast. Breast tissue: The breast tissue of an adult female is composed of 15-20 mammary lobes. Its main function is lactation and it also serves to display female characteristics. The mammary gland is composed of many mammary gland lobules, which contain many alveoli. Fat tissue: Fat tissue wraps the entire breast tissue (except the areola). If the fat tissue layer is thick, the breasts will be large, otherwise they will be small. Connective tissue: It is the fiber bundle that connects the superficial chest muscles and the pectoral fascia, which supports and fixes the breast. Blood vessels, lymphatic vessels and nerves: The breasts are rich in blood vessels and nerves. The main functions of blood vessels and lymphatic vessels are to supply nutrients and eliminate waste. The nerves are connected to sensory organs in the breast skin, which sense external stimuli. |
