Write down the following in the correct order for a simple reflex are:
(i) impulse travels in motor fibre
(b) impulse travels in sensory fibre
(c) effector organ stimulated
(d) impulse crosses synapse

Why nerve impulses travel faster in medullated nerve fibres?

Why nerve impulses travel faster in medullated nerve fibres?

True or False : Nerve impulses travel slower in a myelinated nerve fibre than in a non-myelinated nerve fibre.

State whether the following statements are true or false. Correct the false statements. Sensory neurons conduct impulses from the brain and the spinal cord to effector organs like muscles or glands.

What is a nerve impulse? State the direction followed by a nerve impulse while travelling in the body of an organism.

Explain the following processes: (a) Polarisation of the membrane of a nerve fibre. (b) Depolaristion of the membrance of a nerve fibre. (c ) Conduction of nerver impulse along a nerve fibre. (d) Transmission of a berve impulse across a chemical synapse.
