Which one of the following statements is correct?

biology control and coordination in living organisms feedback mechanism mechanism of hormone action and feedback mechanisms role of hormones in coordination

  1. Endocrine glands regulate neural activity, but not vice versa

  2. Neurons regulate endocrine activity, but not vice versa

  3. Endocrine glands regulate neural activity, and nervous system regulates endocrine glands

  4. Neither hormones control neural activity nor the neurons control endocrine activity

Show answer
Correct Option: C
Explanation:

Endocrine system, like the nervous system, is meant for internal communication and regulation of the animal body. These two systems operate in a coordinated way on many occasions. Many important functions of the endocrine system are infact, under the control of nervous system. Therefore, the two systems are often collectively called as neuroendocrine system

  1. Thyroid Gland

  2. Hypothalamus

  3. Pituitary Gland

  4. Pineal Gland

Show answer
Correct Option: B
Explanation:
Growth hormone–releasing hormone (GHRH), also known as somatocrinin or by several other names in its endogenous forms and as somatorelin (INN) in its pharmaceutical form, is a releasing hormone of growth hormone (GH). It is a 44-amino acid peptide hormone produced in the arcuate nucleus of the hypothalamus.

  3. Thyroxine

  4. Stimulating Hormone

Show answer

  1. Jejunum

  2. Ilem

  3. Duodenum

  4. Islets of Langerhans

Show answer
Correct Option: C
Explanation:

The Pancreas is about 6 inches long and sits across the back of the abdomen, behind the stomach. The head of the pancreas is on the right side of the abdomen and is connected to the duodenum (the first section of the small intestine) through a small tube called the pancreatic duct.

Which cells of the Pancreas helps in conversion of Glycogen to Glucose?

  1. Alpha Cells

  2. Beta Cells

  3. Gamma Cells

  4. Delta Cells

Show answer
Correct Option: A
Explanation:
The pancreas releases glucagon, which is produced by Alpha cells of Pancreas, when the concentration of insulin (and indirectly glucose) in the bloodstream falls too low. Glucagon causes the liver to convert stored glycogen into glucose, which is released into the bloodstream.

Which of the following statements is correct in relation to the endocrine system?

biology control and coordination in living organisms feedback mechanism mechanism of hormone action and feedback mechanisms role of hormones in coordination

  1. Non-nutrient chemicals produced by the body in trace amounts that acts as intercellular messenger are known as hormones

  2. Releasing and inhibitory hormones are produced by the pituitary gland

  3. Adenohypophysis is under direct neural regulation of the hypothalamus

  4. Organs in the body like gastrointestinal tract, heart, kidney and liver do not produce ay hormones

Show answer
Correct Option: A

  2. Hypothyroidism

  3. Diabetes Mellitus

  4. Insomnia

  1. Adrenaline

  2. Cortisone

  3. Insulin

  4. Thyroxine

Show answer
Correct Option: A
Explanation:

The production of adrenaline occurs in the adrenal glands, which sit above the kidneys. Adrenaline is responsible for the fight-or-flight reaction to a threat, and it triggers specific processes in the body. For example, it might make the body send extra oxygen to the lungs to aid a person to run away.

  1. The thyroid secretion is increased in the body due to which the sugar level in the body is increased.

  2. The adrenaline is secreted due to which her mother eats more sweet dishes when seen.

  3. The insulin secretion is decreased due to which the blood sugar level is increased.

  4. The insulin secretion is increased due to which the blood sugar level is increased.

Show answer
Correct Option: C
Explanation:

With too little insulin, the body can no longer move glucose from the blood into the cells, causing high blood glucose levels. If the glucose level is high enough, excess glucose spills into the urine. This makes the body tired and can cause weight loss.
