✅Very important points - Human Reproduction
🌟Uterus also called womb.
🌟 Longest unstripped muscles of the body are found in the walls of uterus. (During pregnancy)
🌟 Clitoris is a homologous to the penis in the male.
🌟 Bartholin Glands : It is homologous to Cowper's gland of male
🌟 A functional mammary gland is characteristic of all female mammals.
🌟 The milk produced during the initial few days of lactation is called colostrum which contains antibodies (IgA) absolutely essential to develop resistance for the new-born babies.
⚡️ Liberation of sperms from Sertoli cells of seminiferous tubules is called spermiation.
⚡️ Liberation of sperms from testes is called semination.
⚡️ Liberation of sperms from body of male is called ejaculation .
⚡️ Mammalian sperms are transfered to vagina of female by the process called insemination.
⚡️ In 1 ml of semen, 20 to 120 millions of sperms are present in human being.
⚡️ Leydig's cells mature at 10 yrs. of age.
⚡️ In humans (and most vertebrates), the first polar body does not undergo meiosis II.
⚡️ The first polar body is, therefore, formed merely to get rid of unwanted chromosomes.
⚡️ 65-74 days are required to complete the cycle of spermatogenesis in human being.
