  • Question 1
    1 / -0
    Which is unpaired gland in male reproductive system of human?
    Solution
    In humans, the male reproductive system consists of the following organs:
    2 testes in the scrotum, 2 epididymides, 2 deferent ducts (vas deferens), 2 spermatic cords, 2 seminal vesicles, 2 ejaculatory ducts, 1 prostate gland, 1 penis. The prostate gland is the unpaired gland that lies in the pelvic cavity in front of the rectum, secretes a thin, milky fluid, that makes up about 30% of semen, and gives it its milky appearance. It is slightly alkaline, which provides a protective local environment for sperm arriving in the acidic vagina. 
    Thus, option C is correct.
  • Question 2
    1 / -0
    In mammals, corpus luteum is found in which organ?
    Solution
    During menstruation in human females, rapid secretion of LH leading to its maximum level during the mid-cycle is called as LH surge which induces rupture of Graafian follicle and thereby the release of ovum (ovulation). 
    The ovulation (ovulatory phase) is followed by the luteal phase during which the remaining parts of the Graafian follicle transform as the corpus luteum. The corpus luteum secretes large amounts of progesterone, which is essential for maintenance of the endometrium. Such an endometrium is necessary for implantation of the fertilised ovum and other events of pregnancy.
  • Question 3
    1 / -0
    Loss of reproductive capacity in women after age of 45 years is termed as
    Solution
    In (female) human beings, menstrual cycle ceases around 45-50 years of age; that is termed as menopause. Cyclic menstruation is an indicator of normal reproductive phase and extends between menarche (onset of puberty) and menopause.
  • Question 4
    1 / -0
    Luteal phase is the other name of
    Solution
    In human females, it is estradiol (and perhaps other species of estrogen) and progesterone, which produce menstrual changes in the ovaries and uterus and throughout the body. The hormones involved in the menstrual cycle may also interact with the nervous system to modify the menstrual response. The total cycle may be divided into three parts: the menstrual phase (flow of blood), which lasts about 5 days on average; the follicular (or proliferative) phase, which follows the cessation of flow and lasts about 9 days; and the luteal (secretory) phase, which comprises about the last 2 weeks of the cycle.
  • Question 5
    1 / -0
    Stages in menstrual cycle are
    Solution
    The menstrual cycle may be divided into three parts: 
    The menstrual phase (flow of blood), which lasts about 5 days on average. The follicular (or proliferative) phase, which follows the cessation of flow and lasts about 9 days; and the luteal (secretory) phase, which comprises about the last 2 weeks of the cycle.
  • Question 6
    1 / -0
    A gland associated with the male reproductive organs of mammals is
    Solution
    The prostate gland lies in the pelvic cavity in front of the rectum and behind the symphysis pubis, surrounding the first part of the urethra. It consists of an outer fibrous covering, a layer of smooth muscle and glandular substance composed of columnar epithelial cells. The prostate gland secretes a thin, milky fluid that makes up about 30% of semen, and gives it its milky appearance. It is slightly alkaline, which provides a protective local environment for sperm arriving in the acidic vagina. It also contains a clotting enzyme, which thickens the semen in the vagina, increasing the likelihood of semen being retained in the vicinity of the cervix.
  • Question 7
    1 / -0
    Graafian follicles contain
    Solution
    The Graafian follicle is a fluid-filled, spherical vesicle in the ovary of a mammal, containing an oocyte attached to its wall, and is responsible for oestrogen production in the ovary. The layer of ovarian follicles is called as theca follicle. It is composed of two layers i.e., theca externa and theca interna. Theca Interna is a highly vascularized layer of collagen fibre, fibroblast and the cuboidal cell which acts as endocrine cells of the ovary. It secretes androgen which is the precursor of oestrogen. Theca externa, the outer layer, loose connective tissue with smooth muscle cells. Thus, the answer is option C. 
  • Question 8
    1 / -0
    Which set is related?
    Solution
    In human females, rapid secretion of LH leading to its maximum level during the mid-cycle, called as LH surge induces rupture of mature (Graafian) follicle and thereby the release of an ovum (ovulation). 
    The ovulation (ovulatory phase) is followed by the luteal phase during which the remaining parts of the Graafian follicle transform as the corpus luteum. 
    The corpus luteum secretes large amounts of progesterone, which is essential for maintenance of the endometrium.
    The sebum is excretory secretion produced by holocrine sebaceous glands. It is not sweet in taste. 
    A pacemaker in the heart is a term used to describe the SAN or sinoatrial node in auricle, which initiates the heart beat. 
    Vitamin $$B_7$$ is biotin, not niacin.
  • Question 9
    1 / -0
    In mammals, maturation of sperms take place at a temperature
    Solution
    In mammals, successful spermatogenesis takes place at a temperature about 3$$^{o}$$C below normal body temperature. The testes are cooled by their position outside the abdominal cavity and the thin outer covering of the scrotum has very little insulating fat.
  • Question 10
    1 / -0
    Spermatogenesis process occur in
    Solution

    CORRECT OPTION – B
    EXPLANATION FOR CORRECT OPTION -

    • Testes are made up of many seminiferous tubules lined by germinal epithelium.
    • The spermatogonia (2N) present at the inner side of the seminiferous tubules multiply by mitotic divisions and increase in number.
    • They stop undergoing mitosis, grow and become primary spermatocytes (2N). 
    • Each primary spermatocyte undergoes meiosis to form two equal haploid secondary spermatocytes (N). 
    • Each secondary spermatocyte then undergoes a second meiotic division to form four equal haploid cells called spermatids (N). 
    • Spermatids receive nourishment to form sperms by the process called spermiogenesis.
