Unmyelinated nerve fibres are enclosed by

(1) Schwann cells

(2) Myelin sheath

(3) No shwann cells and myelin sheath

(4) Schwann cells but not myelin sheath

(1) Autonomous

(2) Somatic Neural systems

(3) Both A and B

(4) CNS

(1) Cranial nerves

(2) Spinal nerves

(3) Both A and B

(4) Not in CNS

(1) Their membranes are in unpolarized state

(2) There membranes are very light to create channels

(3) They have got neurotransmitters

(4) Their membranes are in polarized state

(1) Different kind of lipids are there over membrane

(2) Different kinds of ion channels are there in membrane

(3) These ion channels are selectively permeable to different ions

(4) Both B and C

(1) It is not conducting any impulse

(2) Axonal membrane is more permeable to potassium ions

(3) Axonal membrane won't allow any flow of sodium ions across it

(4) Membrane is impermeable to negatively charged proteins

(1) Axoplasm has more number of Potassium ions

(2) Axoplasm has less number of sodium ions

(3) High Concentration of negatively charged proteins in fluid outside axoplasm

(4) Both B and C

(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
