Which is the correct order of the parts of a neuron? a. synapse, axon, cell body, dendrites b. cell body, dendrites, axon, synapse c. dendrites, cell body, axon, synapse d. dendrites, axon, synapse, cell body?

Neuron is a cell of the nervous system that is involved in carrying of impulses between the nervous system and the rest of the body. There are three types of neurons namely; relay neuron, motor neuron and the sensory neuron. Neuron is made up of various parts that enhance is activity in transmission of impulses/information which includes, dendrites, cell body, axon, myelin sheath among others. The conduction of information in the neuron starts from the Dendrites, then to the cell body, to axon and then to synapse where a neuron links with another and the process is repeated. Therefore; the correct answer is C

The correct order of the parts of the neuron with respect to the direction of the action potential is "dendrite, cell body, axon, synapse".

The dendrites receive impulses from the synapse of another neuron. Then these impulses are propagated towards the neuron cell body then to the axon. In some nerves, axons are wrapped by myelin sheath and the impulses travel per node of Ranvier (saltatory conduction), which offers faster transmission of signals. Then the impulse or action potential will trigger series of events that will eventually lead to the release of neurotransmitters and transmit impulses to another neuron.

Answer: the dna polymerase checks for errors in dna to prevent replication mistakes.
i hope this !
