Ionic gradients across the resting membrane are maintained by

(1) Active transport of ions

(2) RMP

(3) Impulse or stimulus

(4) Both A and B

(1) Responsible for transfer of 3 sodium outwards and two potassium inwards

(2) Responsible for 2 sodium outwards and three potassium inwards

(3) Responsible for 2 sodium and three potassium inwards

(4) Responsible for 2 sodium and three potassium outwards

(1) Negative from outside

(2) Negative from inside

(3) Positive from inside

(4) Both A and C

(1) Electrochemical potential

(2) Electrical potential

(3) Chemical

(4) Chemiosmotic

(1) It becomes freely permeable to Sodium ions

(2) It becomes freely permeable to potassium ions

(3) It causes reversal of polarity from positive to negative on inner side

(4) Both A and C

1. Called as depolarization

2. Called as repolarization

3. Called as polarization

4. Called as hyperpolarization

1. b-a-c-d

2. a-b-c-d

3. b-a-d-c

4. c-a-d-b

1. Synapse

2. Junction

3. Both 1 and 2

4. Current only

(1) Pre synaptic neuron

(2) Post synaptic neuron

(3) Synaptic cleft

(4) None of these

(1) No synaptic cleft

(2) Pre synaptic membranes and post synaptic membranes are in close association with each other

(3) Electric current flow directly from one neuron to other neuron through synapse

(4) Very common synapse in our system
