Which of the following is not a division of the human nervous system? (A) Peripheral, (B) endocrine, (C) central.
This question asks us about the organization of the human nervous system. So, to identify the correct answer choice, let’s review what we know about how the human nervous system is organized.
This is a representation of the human nervous system. It is split into two main divisions: the central and peripheral nervous systems.
The central nervous system is composed of the brain and the spinal cord, which are protected by the skull and the spine, respectively. The brain itself serves as the command center and coordinates all of our activities in response to signals received from the peripheral nervous system. The spinal cord serves as an information superhighway. It is responsible for passing messages from the body to the brain and for transmitting the signals from the brain to the body.
The peripheral nervous system composes all of the nervous tissues not part of the brain and the spinal cord. This includes both sensory and motor neurons, which carry and respond to the signals from the external and internal environments.
We now recall that the nervous system is split into the central and peripheral nervous system. But our question is asking us to select a division that is not part of the human nervous system. So, we’re looking for the answer that is neither the central or peripheral nervous system. With this in mind, we’re able to answer our question. The division which is not part of the human nervous system is the endocrine.
