Commissures, including the corpus callosum, are group of answer choices pockets of oxygen found throughout the brain. brain areas associated with various types of sensory information. blood vessels that carry blood to all areas of the brain. thick bundles of fibers that allow communication between the brain’s hemispheres.

The correct answer will be option-thick bundles of fibers that allow communication between the brain’s hemispheres.

Explanation:

Cerebral commissures are the thick fiber tract composed of white matter which connects the same cortical areas of the left and right hemispheres of the brain.

Commissural fibers include many types of fibers in which corpus callosum fibers are one of the types of fibers which act as the main Cerebral commissures.

Since these fibers connect the two hemispheres, therefore, they help in the communication between two hemispheres.

Thus, the selected option is the correct answer.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
