B Correct answer
Explanation

Development of fetus from the time of conception until birth is called as gestation period.

Foetal ejection reflex in human female is induced by

  1. Release of oxytocin from pituitary

  2. Pressure exerted by amniotic fluid

  3. Differentiation of mammary glands

  4. Fully developed foetus and placenta
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Parturition is an induced Complex neuroendocrine mechanism. In this signals are originated from a fully developed fetus and placenta. This lead to mild uterine contractions and hence fetal ejection reflex. Then oxytocin acts on uterine muscles leading to strong uterine contractions. This further continues to stronger and stronger contractions. As a result, the baby is expelled out of the uterus with placenta through the birth canal. 

So, the correct answer is 'fully developed fetus and placenta'

Which of the following is not the reason for very high load of bilirubin in a new born?

  1. Excessive red blood corpuscles in the new born burst, releasing bilirubin.

  2. Insoluble bilirubin in the intestine is reabsorbed by the blood.

  3. Liver of the new born is too young to cope with the heavy load of bilirubin.

  4. Mother's milk contains a high amount of bilirubin.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

End of pregnancy leads to the initiation of the lactation period. This helps the mother in feeding the newborn. The milk produced during the initial few days of lactation is called colostrum which contains several antibodies and high content of bilirubin which protects the newborn baby.

So, the correct option is 'Mother's milk contains a high amount of bilirubin'.

Match the columns and find the correct options.

Column I Column II
a Parturition p Attachment of zygote to endometrium
b Gestation q Release of egg from Graafian follicle
c Ovulation r Delivery of baby from uterus
d Implantation s Duration between pregnancy and birth
e Conception t Formation of zygote by fusion of egg and sperm
u Stoppage of ovulation and menstruation

  1. a-q, b-s, c-p, d-t, e-r

  2. a-s, b-r, c-p, d-t, e-q

  3. a-t, b-p, c-q, d-r, e-s

  4. a-r, b-s, c-q, d-p, e-t
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Parturition is also called as childbirth. It is the act of delivering baby from uterus. Gestation is a period of developing embryo from conception to birth. It is a duration considered between pregnancy and birth. Ovulation is a process of releasing of egg from the ovary or Graafian follicle. Implantation is the process in which fertilized egg or zygote adheres or attaches to the endometrium wall of the uterus. Conception is the act of conceiving  a baby. In this, zygote is formed from the fusion of egg and sperm.

Thus, the correct answer is 'a-r, b-s, c-q, d-p, e-t.'

Which is called milk ejection hormone?

  1. Prolactin

  2. Oxytocin

  3. Vassopressin

  4. Luteinizing hormone
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The release of the hormone oxytocin from maternal pituitary which leads to the milk ejection.  Oxytocin stimulates the muscle contraction surrounding the breast to squeeze out the milk. 

so, the correct option is 'Oxytocin'.

Signals for parturition originate from

  1. Fully developed foetus only

  2. Placenta only

  3. Oxytocin released by maternal pituitary

  4. Both A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Parturition is an induced Complex neuroendocrine mechanism. In this signals are originated from a fully developed fetus and placenta. This lead to mild uterine contractions and hence fetal ejection reflex. Then oxytocin is released from maternal pituitary and it acts on uterine muscles leading to strong uterine contractions. This further continues to stronger and stronger contractions. As a result, the baby is expelled out of the uterus with placenta through the birth canal. 

so, the correct option is 'Both A and B'.

Which of the following statement is correct?

  1. Foetal heart is formed in second month

  2. Foetus shows movements for the first time in seventh month

  3. hPL has a major role in parturition

  4. Signal for parturition comes from fully developed foetus and placenta

Parturition is an induced Complex neuroendocrine mechanism. In this signals are originated from a fully developed fetus and placenta.

Multiple choice zoology menustral cycle in human parturition and lactation pregnancy and birth fertilization and post fertilization in humans

Which of the following hormones initiate parturition?

  1. ACTH, hCG, oxytocin

  2. ACTH, corticosteroid, oxytocin

  3. Corticosteroid, ACTH, prostaglandin

  4. ACTH, progesterone, hCG
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Parturition is the process in which a mother gives birth to its young one. It initiates when the message initiating parturition starts with the fetal brain, its control of ACTH release from the pituitary, and increased cortisol production by the fetal adrenal. The cortisol stimulates placental enzymes which cause placental progesterone to be made into estrogen. Oxytocin leads to the contraction of smooth muscles of myometrium of the uterus, which directs the full term foetus towards the birth canal.

So the correct option is 'ACTH, corticosteroid, oxytocin'.

Forceful muscular contractions of uterine wall are involved in

  1. Implantation

  2. Lactation

  3. Micturition

  4. Parturition
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Parturition or childbirth is the event of bringing a child into the world from the uterus of the mother. It is the apotheosis of pregnancy. It involves forceful muscle contractions of the uterine wall which push the child out of the womb through the vaginal canal.

So, the correct answer is 'Parturition'.

Multiple choice zoology menustral cycle in human parturition and lactation pregnancy and birth fertilization and post fertilization in humans

The signals for parturition originate from

  1. Placenta only

  2. Placenta as well as fully developed foetus

  3. Oxytocin released from maternal pituitary

  4. Fully developed foetus only
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Parturition is the process of giving birth or delivery. The signals for parturition originate from the placenta as well as fully developed foetus. Both these induces uterine contractions. These uterine contractions are called as foetal ejection reflex. This then stimulates the release of oxytocin hormone from the maternal pituitary gland. 

Thus, the correct answer is 'Placenta as well as fully developed foetus.'
