(b) Impulse conduction in myelinated nerve fiber and unmyelinated nerve fiber
(c) Aqueous humor and vitreous humor
(d) Blindspot and yellow spots
(e) Cranial nerves and spinal nerves

Answer 1

Hint: Our nervous system is basically of two types; the first one is the central nervous system which includes the brain and spinal cord and the second one is the peripheral nervous system which consists of a network of neurons, spans the organ, muscle, and the body.
Different and different neurons interface the central nervous system (CNS) to create a signal transmission pathway, which coordinates function in the body. The brain and spinal cord are responsible for the formation of the central nervous system.

Complete answer:

Afferent neurons	Efferent neurons
Afferent neurons perform the sensory impulses from the receptors to the central nervous system.	Different neurons perform motor impulses from the central nervous system to the effector organs like muscles.
They are present in the sense organs.	They are taking place in the brain and the spinal cord.
They are sensory neurons.	They are motor neurons.
Its shape is rounded and smooth.	The shape of different neurons is satellite shaped.

Additional information: The third type of neuron is called the interneuron or association neuron, which acts as a middleman between the afferent and efferent neurons. These neurons are situated in the central nervous system (the brain and spinal cord). Different and different neurons need to cooperate so as to detect and react to stimulus, but they don't straightforwardly associate.

Association neurons help to bridge the gap for relaying the information between sensory and motor neurons.

Note: Different and different neurons are important for your somatic nervous system, which is responsible for all the voluntary muscle developments in your body. At the point when you kick a ball, scratch your head, or do push-ups at the exercise center, afferent and efferent neurons are assessing improvements and permitting you to react. Interneurons, then again, are an essential part of the central nervous system.
