Answer 1

Answer:

Classes of neurons

Based on their roles, the neurons found in the human nervous system can be divided into three classes: sensory neurons, motor neurons, and interneurons.

Answer 2

Answer:

➣ The functional classification of neuron are :-

↬ On the basic of function , neurons are of three types :-

1) Sensory neuron : The neurons, which carry sensory impulse from receptors to the central nervous system, are called sensory neurons . These neurons transfer nerve impulse from outside environment to inside . Therefore, these are also known as afferent neurons .

2) Motor neuron : The neurons, which carry motor impulse from central nervous system to the effector organs or tissues, are called motor neurones .These neuron carry impulse from inside to outside, hence these are also known as efferent neurons .

3) Inter -neuron : The nerve cells present in central nervous system, which transfer impulses from sensory neuron to motor neurons are called inter - neurons. These neurons are also known as relay neurons.

➣ The functions of axon and dendron are :-

The functions of axon and dendron are mentioned below.

1) Axon : Axon conveys nerve impulse from cell body of a neuron to the next neuron or any effector organ.

2)Dendron : Dendron receives nerve impulse from any sensory cell or another neuron and sends it to the cell body .
