Which one of the following statements is correct ?
- Neurons regulate endocrine activity, but not vice versa
- Endocrine glands regulate neural activity and nervous system regulates endocrine glands
- Neither hormones control neural activity nor the neurons control endocrine activity
- Endocrine glands regulate neural activity, but not vice versa
The Correct Option is A
Solution and Explanation
The autonomous nervous system controls the secretion of glands, while the glands do not exert control over the nervous system.
so, the correct option is (A): Neurons regulate endocrine activity, but not vice versa

- Given below are two statements:
Statement I: Fig fruit is a non-vegetarian fruit as it has enclosed fig wasps in it.
Statement II: Fig wasp and fig tree exhibit a mutual relationship as the fig wasp completes its life cycle in the fig fruit and the fig fruit gets pollinated by the fig wasp. - A wire of resistance \(R\) is cut into 8 equal pieces. From these pieces, two equivalent resistances are made by adding four of these together in parallel. Then these two are added in series. The net effective resistance of the combination is:

- An oxygen cylinder of volume 30 litre has 18.20 moles of oxygen. After some oxygen is withdrawn from the cylinder, its gauge pressure drops to 11 atmospheric pressure at temperature \(27^\circ\)C. The mass of the oxygen withdrawn from the cylinder is nearly equal to: [Given, \(R = \frac{100}{12} \text{ J mol}^{-1} \text{K}^{-1}\), and molecular mass of \(O_2 = 32 \text{ g/mol}\), 1 atm pressure = \(1.01 \times 10^5 \text{ N/m}^2\)]

Three identical heat conducting rods are connected in series as shown in the figure. The rods on the sides have thermal conductivity 2K while that in the middle has thermal conductivity K. The left end of the combination is maintained at temperature 3T and the right end at T. The rods are thermally insulated from outside. In steady state, temperature at the left junction is \(T_1\) and that at the right junction is \(T_2\). The ratio \(T_1 / T_2\) is

Chemical Coordination and Integration
The chemical coordination and integration of all physiological functions in the animal body are jointly synchronized by the neural and endocrine systems. The control and coordination of body functions are executed by the endocrine glands. They are ductless glands that secrete severel hormones to control and coordinate body functions.
Human Endocrine System:
The human body has several endocrine glands located in different parts. They cover the pituitary gland, thymus, thyroid gland, pineal gland, parathyroid, pancreas (dual gland), adrenal gland, and gonads (testes and ovaries). The liver, kidney, heart, and gastrointestinal tract also produce hormones in small traces to harmonize the functioning of these organs.
The Hypothalamus comprises groups of secretory cells called nuclei which secrets various hormones. These hormones released by the hypothalamus are important in regulating the synthesis and secretion of pituitary hormones.
Functions of Endocrine Glands:
- Pituitary Gland
- Pineal Gland
- Thyroid Gland
- Parathyroid Gland
- Thymus
- Adrenal Gland
- Pancreas
- Testes
- Ovary
- Hormones of Kidney, Heart, and Gastrointestinal Tract
