1.

Which one of the following is the correct matching of the events occurring during menstrual cycle?

  • Ovulation - LH and FSH attain peak level and sharp fall in the secretion of progesterone

  • Proliferative - Rapid regeneration of myometrium and maturation of Graafian follicle

  • Development of corpus - luteum - Secretory phase and increased secretion of progesterone

  • Development of corpus - luteum - Secretory phase and increased secretion of progesterone


C.

Development of corpus - luteum - Secretory phase and increased secretion of progesterone

In secretory phase during ovulation, the follicle breaks and collapses under the continuous influence of Luteinizing Hormone (LH). It begins to enlarge and forms a yellowish structure, called the corpus luteum. The corpus luteum plays an important role in the preparation of the endometrium for the implantation of the fertilised egg by secreting oestrogens and progesterone.

Which one of the following statement is incorrect about menstruation? 

  • During normal menstruation, about 40 mL blood is lost

  • The menstrual fluid can easily clot

  • At menopause in a female, there is especially abrupt increase in gonadotropic hormones

  • At menopause in a female, there is especially abrupt increase in gonadotropic hormones


B.

The menstrual fluid can easily clot

During normal menstruation, approximately 40 mL of blood and an additional 35 mL of serous fluid are lost. The menstrual fluid is normally non-clotting because a fibrinolysin is released along with the necrotic endometrial material.

The cause of menopause is burning out of the ovaries. At about age 45 only a few primordial follicles remain to be stimulated by FSH and LH. The oestrogen production falls below a critical value and the gonadotropic hormones (FSH and LH)  are produced regularly from the pituitary so, a there level increase in body.

Foetal ejection reflex in human female is induced by 

  • the pressure exerted by the amniotic fluid

  • the release of oxytocin from pituitary

  • fully developed foetus and placenta

  • fully developed foetus and placenta


B.

the release of oxytocin from pituitary

Oxytocin (childbirth hormone) secreted by neurohypophysis of pituitary gland stimulates contraction of uterus muscles, including labour pain for child birth, when secretion of progesterone hormone declines, making the end of pregnancy. As the sensory impulse of increasing labour pain reaches hypothalamus, more and more oxytocin is released from posterior pituitary under a positive feedback regulation childbirth, it dilates the cervix (vaginal stretching).

The crystal of lead zirconate is a key component of

  • electroencephalography

  • electrocardiography

  • magnetoencephalography

  • sonography


D.

sonography

Sonography is a technique to visualise the structures beneath the skin. A transducer is used to recieve soundwave and signals to the skin. The transducer contains the crystals of lead zirconate that convert electric current into sound waves. It also acts as a reciever and converts the echoes into electrical signals which are processed and displayed on the screen of a monitor to show 2-D image.
