The potential, difference across the membrane of nerve fiber when it does not show any physiological activity is called resting potential. It is about.
1 \(-60 \mathrm{mV}\)
2 \(-70 \mathrm{mV}\)
3 \(+60 \mathrm{mV}\)
4 \(+90 \mathrm{mV}\)
Explanation:
B The potential difference across the membrane of nerve fibre when it does not show any physiological activity is called resting potential. The resting potential of a nerve cell, is approximately - 70 millivolts.

Which of the following statement is true?
1 Saltatory conduction is seen in nonmyelinated nerve fibres
2 Nissl's granules are found in muscle fibres
3 Non-myelinated nerve fibres do not possess nodes of Ranvier
4 Non-myelinated nerve fibres are completely enclosed by myelin sheath
Explanation:
C Nodes of Ranvier are gaps in the myelin sheath that occur in myelinated nerve fibers, allowing for saltatory conduction. Non-myelinated nerve fibers lacks nodes of Ranvier and have a continuous unmyelinated sheath.

Neurons of people suffering from diabetes insipidus do not secrete
1 Enzyme
2 Steroid
3 Fatty acid
4 \(\mathrm{ADH}\)
Explanation:
D Neurons of people suffering from diabetes insipidus do not secrete antidiuretic hormone (ADH), which play an important role in regulating water balance in the body by controlling the reabsorption of water in the kidneys. This condition leads to excessive thirst and production of dilute urine.

During the conduction of nerve impulse, the action potential is the result of movement of
1 \(\mathrm{Na}^{+}\)from intracellular fluid to extracellular fluid
2 \(\mathrm{Na}^{+}\)from extracellular fluid to intracellular fluid
3 \(\mathrm{Na}^{+}\)towards both directions
4 None of the above
Explanation:
B During the conduction of a nerve impulse, there is a movement of sodium ions \(\left(\mathrm{Na}^{+}\right)\)from the extracellular fluid into the intracellular fluid, leading to depolarization of the cell membrane. This depolarization is a key step in the propagation of the nerve impulse.
