Reproduction System and Embryology Quiz-03

Dear Readers,

NEET is the most famous and important medical entrance examination held in our country. This exam is an objective type, an offline test which includes 4 sections namely– Physics, Chemistry, Botany, and Zoology. The maximum marks that can be scored are 720 marks and have 180 questions. About half of the paper consists of questions from Biology, as the NEET exam essentially focuses on capacitating students to go for seats in medical courses. One of the most significant and crucial sections in the NEET exam is of Biology. It comprises of theories, descriptions, discoveries, diagrams, definitions, explanations of differences, and relations. The majority of the topics covered in the NEET syllabus are from the NCERT syllabus of Class 11 & 12 and other related sources become part of the rest of the syllabus. Clear Exam curates a list of articles selected by professionals who recommend the highly vital topics for NEET exams.

Prior to solving NEET question papers or practicing mock tests, you must ensure to study the basic concepts in NEET and practice a few sample questions related to this exam. Students will be covered for all their studies as the topics are available from basics to even the most advanced. .

Q1.   Primary spermatocyte differs form spermatogonium in
  •  Number of chromosomes
  •  Size and volume
  •  DNA content
  •  Size of chromosomes
Solution
(b) Undifferentiated primordial germ cells undergo mitotic division to produce spermatogonia. Each spermatogonium grows to a large primary spermatocyte by obtaining nutrients from the nursing cells. The DNA content remains same (2n) in both spermatogonia and primary spermatocyte.

Q2.   Notochord, skeletal system and dermis of the skin are the derivatives of
  •  Mesoderm
  •  Endoderm
  •  Ectoderm
  •  All of these
Solution
(a) Notochord, connective tissues including loose areolar tissue, ligaments, tendons, dermis of skin, specialized connective tissue like adipose tissue, reticular tissue, cartilage and bones are mesodermal in origin.

Q3.   The reproductive cycle in the female primate monkeys, apes and human beings is called
  •  Menstrual cycle
  •  Menarche
  •  Menopause
  •  ovulation
Solution
(a) Menstrual Cycle (i) The rhythmic series of changes that occurs in the reproductive organs of female primates (monkeys, apes and human beings) is called menstrual cycle. (ii) It is repeated at an average interval of about 28/29 days. The first appearance of menstruation at puberty is called menarche

Q4.   Insemination is
  •  A sperm injection to increase male fertility
  •  A cure of male infertility
  •  Inability of male to produce sperms
  •  The transfer of sperms by male in to the genital tract of female
Solution
(d) Transfer of sperms by male in genital tract Gametes. The major reproductive events in human beings are as follows (i) Gametogenesis It is the formation of gametes. It includes spermatogenesis (formation of sperms) and oogenesis (formation of ova/eggs) (ii) Insemination It is the transfer of sperms by the male into the genital tract of the female (iii) Fertilization Fusion of male and female gametes to form zygote is called fertilization (iv) Cleavage It is rapid mitotic divisions of the zygote which convert the single celled zygote into a multicellular structure called blastocyst (blastula) (v) Implantation It is the attachment of blastocyst to the uterine wall (vi) Placentation It involves the formation of placenta which is the intimate connection between the foetus and uterine wall of the mother to exchange the materials (vii) Gastrulation It is the process by which blastocyst is changed into gastrula with three primary germ layers (viii) Organogenesis It is the formation of specific tissue, organs and organ systems from three primary germ layers (ix) Parturition (child birth) it involves expelling of the baby from the mother’s womb (uterus)

Q5.   Follicular phase is also called
  •  Secretory phase
  •  Luteal phase
  •  Proliferative phase
  •  Menstrual phase
Solution
(c) Follicular phase is also called the proliferative phase. Generally, menstrual cycle have four phases (i) Menstrual phase (a) The soft tissue of endometrial lining of the uterus disintegrates causing bleeding. (b) The unfertilized egg and soft tissue are discharged. (c) It lasts 3-5 days. (ii) Follicular Phase/Proliferative Phase (a) The primary follicles in the ovary grow and become a fully mature Graafian follicle. (b) The endometrium of the uterus is regenerated due to the secretion of LH and FSH from anterior pituitary and ovarian hormone, estrogen. (c) It least for about 10-14 days. (iii) Ovulatory Phase (a) Rapid secretion of LH (LH surge) induces rupture of Graafian follicle, thereby leading to ovulation (release of ovum). (b) It lasts for only about 48 hr. (iv) Luteal Phase/Secretor Phase (a) In this phase the ruptured follicle changes into corpus luteum in the ovary and it begins to secrete the hormone progesterone. (b) The endometrium thickens further and their glands secrete a fluid into the uterus. c) If ovum is not fertilized, the corpus luteum undergoes degeneration and this causes disintegration of the endometrium leading to menstruation

Q6.   The seminiferous tubules of the testis opens into the vasa efferentia by
  •  Vasa deferentia
  •  Rete testis
  •  Epididymis
  •  Seminiferous tubules
Solution




Q7.   Which is formed in gastrulation?
  •  Archenteron
  •  Heart
  •  Brain
  •  None of these
Solution
(a) Gastrulation is the process by which a blastula is converted into gastrula. By the end of gastrulation three layered embryo is formed, which is enclosing an archenteron.

Q8.   The tertiary follicle changes into
  •  Graafian follicle
  •  Oocyte
  •  Megaspore mother cell
  •  ovum
Solution
(a) A tertiary follicle changes into the mature follicle or Graafian follicle. The secondary oocyte forms a new membrane called zona pellucida surrounding it. The Graafian follicle ruptures to release the secondary oocyte (ovum) from the ovary by the process called ovulation

Q9.   The main function of fimbriae of Fallopian tube is
  •  Help in development of ovary
  •  Help in collection of the ovum after ovulation
  •  Help in development of ova
  •  Help in fertilization
Solution
(b) The part of the Fallopian tubes (oviducts) closer to the ovary is the funnel-shaped infundibulum. The edges of the infundibulum possess finger-like projections called fimbriae, which help in collection of the ovum after ovulation

Q10.   Acrosome is a part of
  •  Foetus
  •  Graafian follicle
  •  Human ovum
  •  Human sperm
Solution
(d) Acrosome is a part of human sperm.
