Which of the following is true about neural system
| 1. | It provides point to point rapid coordination among organs |
| 2. | Coordination is fast and short lived |
| 3. | Response is very quick in it |
| 4. | All of the above |
| 1. | Hormones are secreted into the blood stream and act over long distances at specific target organs. |
| 2. | Hormones are substances that almost always cause muscles to contract. |
| 3. | Hormones have no impact on the nervous or enteric systems. |
| 4. | Hormones are always derived from food and never synthesised. |
Which of the following is true about Endocrine glands
| 1. | Ductless glands |
| 2. | Secretion is hormones |
| 3. | Pour its secretion into lymph and venous blood |
| 4. | All of these |
| 1. | Nutrient chemicals produced by endocrine glands. |
| 2. | Non-nutrient chemicals that act as intercellular messengers produced in large amounts. |
| 3. | Non-nutrient chemicals that act as intercellular messengers produced in trace amounts. |
| 4. | Nutrient chemicals that regulate the body’s metabolism. |
The system which coordinate and regulate the physiological functions in the body is
| 1. | Nervous System and Excretory system |
| 2. | Endocrine System and Circulatory system |
| 3. | Nervous System and Endocrine System |
| 4. | Excretory and Circulatory system |
Which of the following is true about Endocrine system
| 1. | It is not directly connected with organs |
| 2. | Response is slow |
| 3. | coordinates through secretion of hormones |
| 4. | All of the above |
| 1. | Nutrient chemicals produced by endocrine glands in large amounts and transported through blood to nearby tissues |
| 2. | Non-nutrient chemicals which act as intercellular messengers and are produced in trace amounts |
| 3. | Protein molecules synthesized only by organized endocrine glands and secreted through ducts |
| 4. | Lipid-soluble substances that provide energy to cells and are produced in high concentrations |
| Assertion (A): | Although hormones are circulated by blood they act only on their target tissues. |
| Reason (R): | Hormones produce their effects on target tissues by binding to specific proteins called hormone receptors located in the target tissues only. |
| 1. | (A) is True; (R) is False. |
| 2. | Both (A) and (R) are True but (R) does not correctly explain (A). |
| 3. | Both (A) and (R) are True and (R) correctly explains (A). |
| 4. | (A) is False; (R) is True. |
| Assertion (A): | Endocrine glands are ductless glands. |
| Reason (R): | Hormones of endocrine glands directly enter in the blood circulation. |
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are true, but (R) is not the correct explanation of (A). |
