Nervous System Physiology

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.

The pons varolii contains nerve fibers that connect the cerebellum to the rest of the brain, including the corpora quadrigemina.

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

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).

The medulla oblongata contains the cardiovascular center, which regulates heart rate and blood vessel diameter. It is the primary control center for autonomic cardiac regulation.

The medulla oblongata is the control center for many autonomic functions, including respiration, cardiovascular reflexes, and various digestive processes like gastric secretion.
