Foetal ejection reflex in human female is induced by:A. pressure exerted by amniotic fluidB. release of oxytocin from pituitaryC. fully developed foetus and placentaD. differentiation of mammary glands |
|
Answer» Correct Answer - B Oxytocin (child birth hormone) secreted by neurohypophysis of pituitary gland stmulates contractio of uterus muscles. It stimulates labour pain for chid birth. When secretion of progesterone hormone declines it will result in 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, it dilates the cervix (vaginal stretching) |
|

The blood calcium level is lowered by the dificiency ofA. ParathormoneB. thyroxineC. calcitoninD. Both (a) and (c) |
|
Answer» Correct Answer - A The chief cells of the parathyroid secrete parathormone. Its deficiency causes the lowering of blood calcium level. This increases the excitability of nerves and muscles causing cramps and convulsion. This causes parathyroid tetany characterised by sustained contractions of the muscles of larynx, face, hands and feet. Calcitonin is secreted when calcium level is high in blood. it has an opposite action to that of paradthyroid homone and lowers the calcium level by suppressing release of calcium ions from the bones. Thyroxine is secreted from the thyroid gland. It regulates the metabolic rate of the body and thus, maintain basal metabolic rate, stimulate protein synthesis and therefore, promote growth of the body tissues. |

The signal trasnduction of steroid hormone across cell is thorughA. binding of hormone to the cytoplasmic receptor and the complex binds to hormone response element on DNA within promoter DNAB. binding of hormone to the transmembrane receptor which intiates the production of second messenger that activates enzymes which further activates transcription factorsC. binding of hormone ot the transmembrane receptor which diffuse inside the cell cytoplasm and then activates the enzyme necessary for the activation of transcription factors.D. binding of hormone to the cytoplasmic r aceptor that initiates the production of second messenger which activates enzymes that further activates transcription factors. |
|
Answer» Correct Answer - A Steroid hormones, being hydrophobic molecules, diffuse freely into all cells and act within the cell. Steroid hormones eneter the cytoplasm of a target cell and bind with specific recptor proteins (mobile). Hormone -receptor complex then diffuses into nucleus and activates specific response for a particular steroid hormone. |

Which one of the following hormones never reaches to cytoplasm?A. EstrogenB. FSHC. ProgesteroneD. testosterone. |
|
Answer» Correct Answer - B FSH is a proteinaceous hormone it does not enter its target cells, thus, it never reaches to cytoplas. Instead. It binds to the recptor present on the cell membrane and activates a membraen bound enzyme that causes conversion of ATP to cAMP. This then alters the activites of enzymes in the cytoplasm. |
