C Sequence of nerve impulse generation and conduction \(\mathrm{B} \rightarrow \mathrm{D} \rightarrow \mathrm{A} \rightarrow \mathrm{E} \rightarrow \mathrm{C}\). (i) Threshold stimulus (B) : Minimum stimulation required to trigger an action potential. (ii) Influx of \(\mathrm{Na}^{+}\)ions (D): Sodium ions rush in, causing depolarization. (iii) Action potential (A): Short electrical signal traveling along the neuron. (iv) Efflux of \(\mathrm{K}^{+}\)ions (E): Potassium ions leave, repolarizing the membrane. (v) Under shoot/Hyperpolarisation (C): Short period of increased negativity, making the neuron less responsive.

The electrical potential difference between outside and inside of a nerve axon before excitation is known as :
1 Resting potential
2 Action potential
3 Spike potential
4 Reaction potential
5 Activation potential
Explanation:
A The electrical potential difference between outside and inside of a nerve cell before excitation, known as "resting potential". This baseline voltage, typically around \(-70 \mathrm{mV}\), maintains the cell's readiness to transmit signals and it is important for generating action potential. There are generally more sodium particles outside the neuron and more potassium particles inside that neuron.

The path of passage of stimulus when you accidentally touch a hotplate is
D The path of passage of stimulus when you accidentally touch a hotplate is - Receptor \(\rightarrow\) spinal cord \(\rightarrow\) muscles. While touching the hot plate impulse is registered from sensory organs to sensory neurons. Here the impulse travels through the central nervous system (CNS), and take the appropriate actions. After that, the impulse is transferred back to the muscles by using the motor neurons.
