2. thyroxine
3. calcitonin
4. Both 1 and 3
Which one of the following pairs is incorrectly matched?
1. Glucagon- Beta cells(source)
2. Somatostatin- Delta cells(source)
3. Corpus luteum- Relaxin(secretion)
4. Insulin- Diabetes mellitus(disease)

Given ahead is an incomplete table about certain hormones, their source glands and one major effect of each on the body in humans. Identify the correct option for the three blanks A, B and C.
| Gland | Secretion | Effect on Body |
| A | Oestrogen | Maintenance of secondary sexual characters |
| Alpha cells of islets of Langerhans | B | Raises blood sugar level |
| Anterior pituitary | C | Oversecretion leads to gigantism |
| Options: | A | B | C |
| 1. | Placenta | Insulin | Vasopressin |
| 2. | Ovary | Insulin | Calcium |
| 3. | Placenta | Glucagon | Calcitonin |
| 4. | Ovary | Glucagon | Growth hormone |
Match the source gland with its respective hormone as well as the function.
| Source gland |
Hormone | Function | |
| (a) | Posterior pituitary |
Vasopressin | Stimulates reabsorption of water in the distal tubules in the nephron |
| (b) | Corpus luteum |
Prolactin | Supports pregnancy |
| (c) | Thyroid | Thyroxine | Regulates blood calcium level |
| (d) | Anterior pituitary |
Oxytocin | Contraction of uterus muscles during childbirth |
1. (a)
2. (b)
3. (c)
4. (d)
Which one of the following pairs of hormones are the examples of those that can easily pass through the cell membrane of the target cell and bind to a receptor inside it (mostly in the nucleus)?
1. Insulin and glucagon
2. Thyroxin and insulin
3. Somatosatin and oxytocin
4. Cortisol and testosterone
Fight - or - flight reaction cause activation of:
| 1. | the parathyroid glands, leading to increased metabolic rate. |
| 2. | the kidney, leading to suppression of the rennin angiotensin-aldosterone pathway. |
| 3. | the adrenal medulla, leading to increased secretion of epinephrine and norepinephrine |
| 4. | the pancreas leading to a reduction in blood sugar levels. |
