Action potentials travel in only one direction due to the refractory period, which prevents backflow.
Ref: NCERT Class 11 Biology Chapter 18: Neural Control and Coordination Nerve Impulse - Resting Potential Action Potential and Transmission
The sodium-potassium pump moves sodium (Na⁺) out of the neuron and potassium (K⁺) into the neuron.
Ref: NCERT Class 11 Biology Chapter 18: Neural Control and Coordination Nerve Impulse - Resting Potential Action Potential and Transmission
During depolarization, sodium ions (Na⁺) enter the neuron, causing a change in membrane potential.
Ref: NCERT Class 11 Biology Chapter 18: Neural Control and Coordination Nerve Impulse - Resting Potential Action Potential and Transmission
Saltatory conduction occurs in myelinated neurons, where impulses jump between nodes of Ranvier, increasing conduction speed.
Ref: NCERT Class 11 Biology Chapter 18: Neural Control and Coordination Nerve Impulse - Resting Potential Action Potential and Transmission
The sodium-potassium pump maintains the resting membrane potential by actively transporting Na⁺ out and K⁺ into the neuron.
Ref: NCERT Class 11 Biology Chapter 18: Neural Control and Coordination Nerve Impulse - Resting Potential Action Potential and Transmission
The nodes of Ranvier allow saltatory conduction, where the nerve impulse jumps from node to node, increasing conduction speed.
Ref: NCERT Class 11 Biology Chapter 18: Neural Control and Coordination Nerve Impulse - Resting Potential Action Potential and Transmission
The peripheral nervous system (PNS) includes sensory neurons that bring information to the CNS and motor neurons that relay commands from the CNS.
Ref: NCERT Class 11 Biology Chapter 18: Neural Control and Coordination Nerve Impulse - Resting Potential Action Potential and Transmission
During depolarization, sodium ions (Na⁺) rush into the neuron, changing the membrane potential.
