The functional unit of the nervous system is the neuron. To arrive at this answer, let's go through the options:
A. The neuron: Neurons are specialized cells that transmit information in the form of electrical signals throughout the nervous system. They are responsible for conveying and processing information.
B. The brain: While the brain is a crucial component of the nervous system, it is not the functional unit. The brain consists of billions of neurons that work together to process and interpret information.
C. A reflex: A reflex is an involuntary response to a certain stimulus. Although reflexes involve neurons, they are not the fundamental unit of the nervous system.
D. The cerebrum: The cerebrum is the largest part of the brain and plays a key role in higher cognitive functions. However, it is made up of a complex network of neurons and is not a functional unit on its own.
Considering these options, the correct answer is A. The neuron. It is the basic building block of the nervous system and is responsible for transmitting and processing information throughout the body.
