Question

explain the active phase of nerve impulse along a nerve fibre

Answer 1

active phase : when the nerve fibre is simultaneous critically thermally chemically or mechanical a disturbance occurs at the point of simultaneous it is called local excitatory state
the Axon membrane is said to be depolarizing as a result a wave of excitation along the nerve fibre get spread which is called an impulse
thirst during active phase of nerve fibre (potassium) k diffuses out of the exam membrane and( sodium )Na leaving it so that positive and negative charges on the outside and inside of axon membrane or reversed
the change membrane potential is called as action potential
