-
Motor Neurons
-
Corpus Callosum
Correct Answer
A. Corpus CallosumExplanation
Commissural axons are a type of nerve fibers that connect the two hemispheres of the brain. They use the network called the corpus callosum to communicate between the left and right sides of the brain. The corpus callosum is a large bundle of nerve fibers that allows for the transmission of information and coordination of activities between the two hemispheres. It plays a crucial role in integrating and processing information across the brain, enabling communication and coordination of functions between the two sides.Rate this question:

The cerebellum fires ipsilaterally, it does no undergo decussation.
-
True
-
False
Correct Answer
A. TrueExplanation
The cerebellum is responsible for coordinating voluntary movements, balance, and posture. It primarily receives information from the same side of the body it is located on and sends output to the same side as well. This means that the cerebellum fires ipsilaterally, or on the same side, and does not undergo decussation, which is the crossing of nerve fibers from one side of the body to the other. Therefore, the statement is true.Rate this question:

Correct Answer
A. Brain and spinal chordExplanation
The hindbrain attaches to the brain and spinal cord. This is because the hindbrain is the posterior part of the brain that connects to the spinal cord, forming the brainstem. It consists of structures such as the medulla oblongata, pons, and cerebellum, which play vital roles in controlling basic bodily functions, relaying sensory and motor information, and coordinating movement.Rate this question:

Which describes gray and white matter in the central nervous system?
-
Gray is outer, white is inner in the brain.
-
Gray is inner, white is inside in the spinal cord.
-
Gray is darker, outer in the brain; white is lighter, inner.
-
Gray is outside, white is inner in the spinal cord.
Correct Answer
A. Gray is darker, outer in the brain; white is lighter, inner.Explanation
In the central nervous system, the distinction between gray and white matter varies in the brain and spinal cord. In the brain, gray matter constitutes the darker, outer region, while white matter forms the lighter, inner section. Conversely, in the spinal cord, this arrangement is reversed, with white matter on the outside and gray matter situated within. This contrast in color and positioning reflects the diverse compositions and functions of these neural tissues, highlighting their crucial roles in processing and transmitting information throughout the nervous system.Rate this question:
