Question
The anterior pituitary^gland releases: a) FSH. b) TSH. c) LH. d) GH. e) all of the above the primary function of ADH is to; a) increase the amount of sodium lost at the kidneys. b) decrease the amount of water lost at the kidneys. c) decrease blood pressure, d) increase digestive absorption. The pituitary hormone that stimulates cell growth and replication by accelerating protein synthesis is: a) Growth hormone, b) ACTH, c) MSH, d) prolactin, e) insulin. The endocrine system and the nervous system are structurally related. Which of the following cells best illustrates this relationship? a) a neuron in the spinal cord, b) a steroid-producing cell in the adrenal cortex, c) a neurosecretory cell in the hypothalamus, d) a brain cell in the cerebral cortex, e) a cell in the pancreas that produces digestive enzymes the hypothalamus controls the anterior pituitary by means of a) releasing hormones, b) second messengers, c) third messengers, d) antibodies. e) cytokines.Explanation / Answer
1. Anteror pituitary is a major part of the endocrine system. It regulates several physiological processes like stress, growth, reproduction and lactation etc. Most common hormones released from anterio pituitary are ACTH, LH, TSH, GH, FSH, MSH, PRL etc. Therefore Option d " all of the above" is the correct answer.
2. ADH or Vasopressin is a neurohypophysial hormone found in most mammals. This hormone helps to increase the urine osmolarity (increased concentration) and decreased water excretion in the body. Therefore the primary function of ADH is to decrease the amount of water lost at the kidneys i.e. Option b
3. The pituitary hormone that stimulates cell growth and replication by accelerating protein synthesis is Growth hormone or GH i.e. Option a
4.Option c, "A neurosecretory cell in the hypothalamus" best illustrates the relationship that the endocrine system and the nervous system are structurally related.
5.The anterior lobe of the pituitary receives hypothalamic-releasing hormones from the hypothalamus. It binds with receptors on endocrine cells in the anterior pituitary which regulate the release of adrenal hormones into the circulatory system. Therefore the hypothalamus controls the anteror pituitary by means of releasing hormones i.e Option a is correct.
