Assertion:Reflex arc comprises of at least one afferent neuron, one efferent neuron and a part of PNS.
Reason:The efferent neuron receivers signal from a sensory organ and transmits the impulse via a ventral nerve root into the PNS.

Part of neuron that receives stimulus from other neuron and transmits it as impulse to cyton

Select the option which appropriately fills up the blanks. The afferent neuron receives signal from a/an ________ and transmits the impulse via a __________ into the spinal cord.

Select the option which appropriately fills up the blanks. The afferent neuron receives signal from a/an ________ and transmits the impulse via a __________ into the spinal cord.

Neurons are the structural and functional unit of nervous system. a) Based on the number of axon and dendrites, how the neurons are classified. b) Give examples for each. c) Which neuron receives signal from a sensory organ and transmit the impulse to CNS.

The efferent neurons carry impulses from the central nervous system to the effector organs.

In a reflex arc, impulse from receptors is carried by afferent neurons towards
