Nervous System Physiology

The pneumotaxic center is a neural center located in the dorsal part of the pons varolii that moderates the functions of the respiratory rhythm center.

The pneumotaxic center is located in the pons, while the respiratory rhythm center is primarily located in the medulla oblongata.

The cerebellum is the part of the brain responsible for coordinating voluntary movements, maintaining balance, equilibrium, and posture.

The medulla oblongata controls involuntary functions like breathing, heart rate, and blood pressure, not temperature regulation. Temperature regulation is primarily the function of the hypothalamus.

The cerebrum is the largest part of the brain and is responsible for higher-level functions, including processing sensory information like speech, hearing, and vision.

The cerebellum is primarily responsible for motor coordination, precision, and timing of movements.

Arbor vitae (tree of life) is the branching white matter structure found in the cerebellum.

Arbor vitae refers to the tree-like branching pattern of white matter inside the cerebellum, visible in sagittal section.

The corpus callosum is a large, C-shaped nerve fiber bundle found beneath the cerebral cortex. It serves as the primary bridge connecting the left and right cerebral hemispheres.

The cerebrum is the largest part of the human brain, accounting for about 85 percent of the brain's weight. It is responsible for higher-order functions like thought, memory, and voluntary movement.

The pallium is the term used to describe the outer layer or roof of the cerebrum in vertebrates. In mammals, this structure develops into the cerebral cortex.

The piamater is the innermost layer of the meninges and is in direct contact with the surface of the brain (cerebrum). The arachnoid and duramater are further away from the brain tissue.

Cerebral peduncles are structures located in the midbrain that connect the cerebrum to the cerebellum and other lower brain regions. They act as pathways for nerve impulses.

The iter (or cerebral aqueduct) is a narrow channel that connects the third ventricle (in the diencephalon) to the fourth ventricle (located near the medulla and cerebellum).
