340532 Which of the following is true about neural membrane?

1 Same type of ion channels present.
2 Ion channels are selectively impermeable.
3 1 and 2
4 All are wrong
BIOXI21: NEURAL CONTROL AND COORDINATION

340533 When a stimulus is applied at a site on the polarised membrane, the membrane at that site becomes freely permeable to

1 \(\mathrm{Na}^{+}\)
2 \(\mathrm{K}^{+}\)
3 \(\mathrm{Na}^{+}\)and \(\mathrm{K}^{+}\)
4 \(\mathrm{Ca}^{++}\)
BIOXI21: NEURAL CONTROL AND COORDINATION

340534 Assertion :
Imbalance in \(\mathrm{Na}^{+}, \mathrm{K}^{+}\)and proteins generate the resting potential.
Reason :
To maintain unequal distribution of \(\mathrm{Na}^{+}\)and \(\mathrm{K}^{+}\)neurons use electrical energy.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect.
BIOXI21: NEURAL CONTROL AND COORDINATION

340535 Read the statements and identify which is TRUE /FALSE
I. The axoplasm inside the axon contains low concentration of \(\mathrm{K}^{+}\).
II. The axoplasm inside the axon contains high concentration of \(\mathrm{K}^{+}\)and negatively charged proteins.
III. The fluid outside the axon contains a low concentration of \(\mathrm{K}^{+}\)
IV. The fluid outside the axon contains a low concentration of \(\mathrm{Na}^{+}\)

1 I and IV are false
