Figure shows human urinary system with structures labelled (a) to (d). Select option which correctly identifies them and gives their characteristics and/or functions.
1. (a) Adrenal gland-located at the anterior part of kidney.
Secretes catecholamines which stimulate glycogen break-down
2. (b) Pelvis-board funnel shaped space inner to hilum, directly connected to loops of Henle
3. (c) Medulla-inner zone of kidney and contains complete nephrons
4. (d) Cortex-outer part of kidney and do not contain any part of nephrons
Somatostatin from the hypothalamus:
| 1. | stimulates secretion of insulin and glucagon by pancreas |
| 2. | inhibits secretion of insulin and glucagon by pancreas |
| 3. | stimulates secretion of growth hormone from anterior pituitary |
| 4. | inhibits secretion of growth hormone from anterior pituitary |
Identify the incorrectly matched pair:
| 1. | Hyposecretion of growth hormone in childhood | Dwarfism |
| 2. | Hyposecretion of growth hormone in adulthood | Cretinism |
| 3. | Hypersecretion of growth hormone in childhood | Gigantism |
| 4. | Hypersecretion of growth hormone in adulthood | Acromegaly |
The only hormone secreted by pars intermedia of hypophysis is:
| 1. MSH | 2. GnRH |

Pars distalis is:
| 1. | the posterior lobe of pituitary made of neural tissue |
| 2. | the well developed intermediate lobe of pituitary in humans |
| 3. | the major part of the adenohypophysis |
| 4. | the connection between anterior pituitary and hypothalamus |
| 1. | Gonadotropins | 2. | ACTH |
| 3. | Prolactin | 4. | Melatonin |
The definition of hormone describes them as having all the following features except:
