what are relay neurons?
A
have long dendrites and axons and are found throughout the body
B
they connect relay and motor neuron together
C
connect sensory and motor neurons together and also connect the other relay neurons
D
they have short dendrites and short axons and are only found in the CNS
Explanation: 

Detailed explanation-1: -Interneurons. Interneurons, which are found only in the CNS, connect one neuron to another. They receive information from other neurons (either sensory neurons or interneurons) and transmit information to other neurons (either motor neurons or interneurons).

Detailed explanation-2: -Although there are billions of neurons and vast variations, neurons can be classified into three basic groups depending on their function: sensory neurons (long dendrites and short axons), motor neurons (short dendrites and long axons) and relay neurons (short dendrites and short or long axons).

Detailed explanation-3: -Relay neurons are found in the brain and spinal cord and allow sensory and motor neurons to communicate. Motor neurons are found in the central nervous system (CNS) and control muscle movements.

Detailed explanation-4: -Relay neurones – the information from sensory neurones is passed to relay neurones, which carry the impulse through the CNS. The relay neurone forms a link (a relay) between the sensory and motor neurones. They have lots of short dendrites, a cell body and a long axon.

Detailed explanation-5: -Relay neurons are widely found in our nervous system, including the Thalamus, spinal cord and lateral geniculate body. They receive a modulating input (background activity) and a reference input.
