There are huge numbers of synapses in the spinal cord and the brain. Explain why this is so. Please help

Answer:

the central nervous system uses these synapses to transfers electrical impulses to the brain through the spinal cord.

Explanation:

For example a stimulus such as bright light is detected by receptor cells, this sends electrical impulses through the sensory neurons and passes them through synapses to relay neurons. The gap between these neurons are called synapses which use neurotransmitters (chemicals) to send the impulse over the gap. Lots of these synapses are in the spinal cord and brain so that more of these impulses can be received and therefore a motor neuron can send an impulse to an effector so a response can be issued, for this example the response would be closing the eyes so that the bright light doesn't damage the eyes- this is an example of a reflex action.

Sorry if this doesn't make sense or I've explained it wrong! I hope I've helped in the slightest!

There are huge number of synapses in the spinal cord and the brain as these synapses are used by the central nervous system to send electrical impulses to the brain via the spinal cord.

Why there are so much synapses in brain and spinal cord?

To illustrate, when a stimulus like as strong light is received by receptor cells, electrical impulses are sent by sensory neurons and sent across synapses to relay neurons. Synapses are the gaps between these neurons that employ neurotransmitters (chemicals) to transfer the impulse across the gap. A lot of these synapses are in the spinal cord and brain so that more of these impulses can be received and thus a motor neuron can send an impulse to an effector so that a response can be issued, for example, closing the eyes so that the bright light does not damage the eyes- this is an example of a reflex action.

As a conclusion, as synapses are employed by the central nervous system to transfer electrical impulses to the brain via the spinal cord, we may assume that there are a large number of synapses in the spinal cord and brain.
