d) Somatotrophic hormones
View Answer
Explanation: Prolactin is produced by a pituitary gland in both males and females but functional only in a female. It is also known as luteotropic hormone. It enables females to produce milk.
3. Which of the following is an accumulation and releasing centre of neurohormone?
a) Hypothalamus
b) Anterior lobe of pituitary gland
c) Posterior pituitary gland
d) Intermediate lobe of pituitary
View Answer
Explanation: Posterior pituitary gland is a part of the endocrine system. Hormones secreted by Posterior pituitary gland include oxytocin and ADH.
4. MSH is produced by _________
a) Anterior lobe of pituitary gland
b) Posterior pituitary gland
c) Parathyroid
d) Pars intermedia of pituitary
View Answer
Explanation: MSH is produced by Pars intermedia of the pituitary. MSH is melanocyte stimulating hormone. It is a peptide hormones and neuropeptides.
5. Sertoli cells are regulated by pituitary hormone known as _________
a) FSH
b) LH
c) GH
d) Prolactin
View Answer
Explanation: Sertoli cells are regulated by pituitary hormone known as FSH. Sertoli cells are found in gonads of male.
6. Trophic hormones are formed by _________
a) Anterior pituitary
b) Middle pituitary
c) Thyroid
d) Posterior pituitary
View Answer
Explanation: Trophic hormones are a hormone that stimulates an endocrine gland to grow and secrete its hormones, in humans tropic hormones are secreted by the Anterior pituitary.
7. Gigantism and acromegaly are due to _________
a) Hyperthyroidism
b) Hyperpituitarism
c) Hypopituitarism
d) Hypothyroidism
View Answer
Explanation: Gigantism and acromegaly are due to Hyperpituitarism. Hyperpituitarism is a condition due to primary hypersecretion of pituitary hormones.
8. Which of the following gland is regarded as a master gland?
a) Adrenal gland
b) Hypothalamus
c) Pituitary gland
d) Thyroid
View Answer
Explanation: Pituitary gland is regarded as the master gland. It is found at the base of the brain. It produces many hormones that travel throughout the body directing certain processes or stimulating other glands to produce other hormones.
9. What is Wermer’s syndrome known as?
a) Men type 1
b) Men type 2
c) Men type 3
d) Men type 4
View Answer
Explanation: Wermer’s syndrome known as Men type 1. It is part of disorders the multiple endocrine neoplasias that affect the endocrine system through the development of neoplastic lesions in the pituitary, parathyroid gland and pancreas.
10. Pars distalis, Pars tuberalis, Pars intermedia belongs to anterior pituitary.
a) True
b) False
View Answer
Explanation: Pars distalis, Pars tuberalis, Pars intermedia belongs to the anterior pituitary. It secretes 6 hormones. anterior pituitary is also known as adenohypophysis.
11. Which hormone causes the contraction of labor?
a) Prolactin
b) Estrogen
c) Progesterone
d) Oxytocin
View Answer
Explanation: Oxytocin is a peptide hormone and neuropeptide. It is produced by paraventricular nucleus of hypothalamus and released by the posterior pituitary.
12. What is Sheeshan’s syndrome?
a) The pituitary adenoma is hemorrhagic and necrotic
b) Pituitary gland is infected with virus
c) Pituitary gland is infected with Bacteria
d) It is the malignancy of the pituitary
View Answer
Explanation: Sheeshan’s syndrome is also known as postpartum pituitary gland necrosis. It is caused by ischemic necrosis due to blood loss and hypovolemic shock during and after childbirth.
13. Which of the following is not released by anterior pituitary gland?
a) Prolactin
b) ADH
c) FSH
d) TSH
View Answer
Explanation: ADH is not released by the anterior pituitary gland. Hormones released by anterior pituitary gland are GH, PRL, FSH, LH, ACTH and TSH.
14. What is Carney complex?
a) Sex linked disorder
b) Autosomal recessive disorder
c) Autosomal dominant disorder
d) Disorder kidney
View Answer
Explanation: Carney syndrome is an Autosomal dominant disorder. It is associated with spotty pigmentation of the skin, endocrine and non endocrine tumors.
15. What is the treatment of GH-oma?
a) Growth hormone analogues
b) Somatostatin analogues
c) Somatostatin inhibitors
d) Surgery
View Answer
Explanation: Somatostatin analogues react with receptors that prevents growth hormone secretion. It does not reduce the tumor size.
