Schwann cells are responsible for the myelination of axons in the peripheral nervous system.
Oligodendrocytes also myelinate axons, but they are found in the central nervous system. Astrocytes and satellite cells help support neurons, but do not contribute myelin to axons.

Which of the following structures is found only in the peripheral nervous system?
Tap to reveal answer
The central nervous system houses the brain and spinal cord only. The peripheral nervous system refers to all other nervous structures in the body.
Free nerve endings are usually located just under the skin, and respond to pain and large changes in temperature, making them part of the peripheral nervous system.
Oligodendrocytes, white matter, and gray matter are only found in the central nervous system. Interneurons are most commonly found in the spinal cord, but can be found in either the peripheral or central nervous system.

The components of the central nervous system are the brain and the spinal cord only. The remaining structures of the nervous system belong to the peripheral nervous system. The hemispheres of the brain and the spinal cord are part of the central nervous system. The hippocampus, cerebellum, hypothalamus, thalamus, and cerebral cortex are structures within the brain. The hippocampus is responsible for memory storage and the cerebellum is associated with balance and coordination. The cerebrum is responsible for processing information and higher thought. These structures are also part of the central nervous system.
The cranial nerves attach directly to the spinal cord, but branch out into the periphery. They are not considered part of the central nervous system. The adrenal glands and parathyroid glands are part of the endocrine system. Though they can respond to stimulation from the nervous system, they cannot be classified as part of the peripheral or central nervous system.
The thymus is an endrocrine gland located above the heart and is not part of the nervous system.

Though the pineal gland is found within the skull, it is not composed of nervous tissue and is not considered part of the central nervous system. Instead, it is an endocrine organ that interacts with the nervous tissue of the brain that surrounds it.
The thalamus and cerebellum are both structures of the brain, and are thus part of the central nervous system. Microglia function as macrophages in the central nervous system to prevent infection within the blood-brain barrier.

Tap to reveal answer
There are two major criteria that can be used to define nervous system categorizations. The first is location in the body. The central nervous system consists only of the brain and spinal cord, while the peripheral nervous system extends throughout the rest of the body. The central nervous system is enclosed by the blood-brain barrier, separating it from the rest of the body. The second classifier is mechanism of control. Some nervous pathways can be controlled voluntarily (somatic), while others are involuntary (autonomic).
The sympathetic and parasympathetic divisions are both peripheral autonomic pathways.

Tap to reveal answer
The central nervous system contains the brain and spinal cord.
All of the other answer choices are divisions of the peripheral nervous system (PNS). The PNS is divided into the autonomic (involuntary) and somatic (voluntary) divisions, and the autonomic divison is further divided into sympathetic ("fight-or-flight" response) and parasympathetic ("rest-and-digest" response) portions.
