About This Quiz

Lactation is the process that involves the secretion and feeding of the offspring with milk from the mammary glands of the mother. It is a vital process that ensures survival of lines.

    Which of the following hormones is not vital in lactation? - ProProfs

    Which of the following hormones is not vital in lactation?

    • Oxytocin

    • Prolactin

    • Progesterone

    • Testosterone

    Correct Answer
    A. Testosterone
    Explanation
    Testosterone is not vital in lactation because it is primarily a male hormone and does not play a significant role in the production of breast milk. Lactation is primarily regulated by the hormones oxytocin, prolactin, and progesterone. Oxytocin stimulates the release of milk from the breasts, prolactin promotes milk production, and progesterone helps prepare the breasts for lactation. While testosterone does have some effects on breast tissue, it is not essential for lactation.

    Which of the following doesn't lactate? - ProProfs

    Which of the following doesn't lactate?

    • Platypus

    • Hen

    • Man

    • Dogs

    Correct Answer
    A. Hen
    Explanation
    Hens do not lactate. Lactation is the process of producing milk by female mammals to feed their young. While platypus, man, and dogs are all mammals and have the ability to lactate, hens are birds and do not possess mammary glands for milk production. Therefore, hens do not lactate.

    Colostrum contain the following substances except  - ProProfs

    Colostrum contain the following substances except 

    • Antibodies

    • Immunoglobulin A

    • Minerals

    • Proteolytic enzymes

    Correct Answer
    A. Proteolytic enzymes
    Explanation
    Colostrum, the first milk produced by mammals after giving birth, is known for its high concentration of antibodies, immunoglobulin A, and minerals. These substances are crucial for providing passive immunity and essential nutrients to newborns. However, colostrum does not contain proteolytic enzymes. Proteolytic enzymes are enzymes that break down proteins, and their absence in colostrum is understandable as their function is not required at this stage.

    Concerning milk ejection mechanism which of these is odd?  - ProProfs

    Concerning milk ejection mechanism which of these is odd? 

    • Spinothalamic tract

    • Posterolateral tract

    • Anterior white commisure

    • Broca's area

    Correct Answer
    A. Broca's area
    Explanation
    The question is asking which option is odd in relation to the milk ejection mechanism. The Spinothalamic tract, Posterolateral tract, and Anterior white commissure are all related to sensory and motor functions in the spinal cord, but Broca's area is a region in the brain that is involved in speech production and language processing. It is not directly related to the milk ejection mechanism, making it the odd option in this context.

    In humans, the process of lactation is usually initiated in pregnancy at the 

    • 18th week 

    • 20th week

    • 14th week

    • 15th week

    Correct Answer
    A. 18th week 
    Explanation
    Lactation is the process of producing milk in the mammary glands. In humans, this process is usually initiated during pregnancy. The correct answer is the 18th week because by this time, the mammary glands have developed enough to start producing milk. This is an important milestone in pregnancy as it prepares the body to nourish the newborn after birth.

    The following are immune components present in colostrum except  - ProProfs

    The following are immune components present in colostrum except 

    • Lactoferrin

    • Lactoperoxidase

    • Complement

    • Hyaluronidase

    Correct Answer
    A. Hyaluronidase
    Explanation
    Colostrum is the first milk produced by mammals after giving birth, and it is rich in immune components that help protect the newborn from infections. Lactoferrin, lactoperoxidase, and complement are all immune components found in colostrum that play important roles in immune defense. Lactoferrin helps to inhibit the growth of bacteria and viruses, lactoperoxidase has antimicrobial properties, and complement is involved in the immune response against pathogens. However, hyaluronidase is not typically found in colostrum. Hyaluronidase is an enzyme that breaks down hyaluronic acid, which is not directly related to immune defense.

    Which of these hormones stimulates growth and differentiation of the alveoli? - ProProfs

    Which of these hormones stimulates growth and differentiation of the alveoli?

    • Prolactin

    • Estrogen

    • Progesterone

    • Growth hormone

    Correct Answer
    A. Prolactin
    Explanation
    Prolactin is a hormone that stimulates growth and differentiation of the alveoli. It plays a crucial role in the development of the mammary glands during pregnancy and lactation. It promotes the production of milk and helps in the formation of alveoli, which are responsible for milk production and secretion. Prolactin also acts on other tissues in the body, including the immune system and reproductive organs. Estrogen and progesterone are involved in the menstrual cycle and pregnancy, while growth hormone primarily regulates growth and metabolism.

    What part of the brain is stimulated when a baby begins to suck? - ProProfs

    What part of the brain is stimulated when a baby begins to suck?

    • Supraoptic nucleus

    • Ventromedullary nucleus

    • Red nucleus

    • Paraventricular nuclei

    Correct Answer
    A. Paraventricular nuclei
    Explanation
    When a baby begins to suck, the paraventricular nuclei in the brain are stimulated. These nuclei are located in the hypothalamus, which is responsible for regulating various bodily functions, including feeding and sucking. Stimulation of the paraventricular nuclei triggers the release of oxytocin, a hormone that plays a role in bonding, social behavior, and milk letdown in breastfeeding mothers. Therefore, the activation of the paraventricular nuclei is essential for the initiation of sucking behavior in infants.

    The autocrine control of lactation is called  - ProProfs

    The autocrine control of lactation is called 

    • Galactopoiesis

    • Pumping

    • Milk ejection reflex

    • Lactation control

    Correct Answer
    A. Galactopoiesis
    Explanation
    Galactopoiesis refers to the autocrine control of lactation. This process involves the maintenance and stimulation of milk production in the mammary glands. It is regulated by various hormones, such as prolactin and oxytocin, which are produced within the body. Galactopoiesis ensures the continuous production of milk to meet the demands of the breastfeeding infant.
