Questions: The basic units of the brain and spinal cord that process, store, and transmit information are the ・ neurons neurotransmitters synapses myelin

The answer is the first one: neurons.

Explanation for each option:

• Neurons: These are the basic units of the brain and spinal cord responsible for processing, storing, and transmitting information. Neurons are specialized cells that communicate with each other through electrical and chemical signals.

• Neurotransmitters: These are chemical messengers that neurons use to communicate with each other across synapses. While they play a crucial role in transmitting information, they are not the basic units themselves.

• Synapses: These are the junctions between neurons where neurotransmitters are released to transmit signals from one neuron to another. Synapses are important for communication but are not the basic units of the nervous system.

• Myelin: This is a fatty substance that surrounds and insulates the axons of some neurons, allowing for faster transmission of electrical signals. Myelin is important for efficient signal transmission but is not a basic unit of the nervous system.

In summary, neurons are the fundamental units of the brain and spinal cord that process, store, and transmit information.
