A large part of the brain situated anterior to and above the medulla oblongata concerned with the coordination of muscles and the maintenance of bodily equilibrium.
That division of the central nervous system postinferior to the cerebrum and above the pons is concerned with coordination of movements and equilibrium.
A section of the hindbrain, located at the back of the head beneath the back part of the cerebrum.
That part of the brain located behind the cerebrum and above the pons and concerned with the coordination and control of voluntary muscular activity.
A large brain structure located dorsal to the pons and medulla that functions to maintain balance, ocular movement, and posture.
A portion of the brain, located in the lower back of the skull and connected to the brain stem. This two- hemisphere structure coordinates balance and muscular movement. The cerebellum is linked to the brain stem via a connection of thick nerve tracts. The nerve fibers from these nerve tracts fan out toward the surface (cortex). The surface itself consists of gray matter (interconnected nerve cells) arranged in three layers. Via the brain stem, the cerebellum receives information from organs, such as the inner ear, concerning the body’s posture and balance. From the muscles, joints, and and tendons, it receives signals about movement. It also receives input about a motor plan for movement originating in the cerebral cortex, and it contains programs for previously learned movements. The cerebrum integrates this information and adjusts movement as it progresses. The cerebellum continually corrects the movement by adjusting signals to the motor nerve cells in the spinal cord and by updating the motor plan.
The largest part of the hindbrain, bulging back behind the pons and the medulla oblongata and overhung by the occipital lobes of the cerebrum. Like the cerebrum, it has an outer gray cortex and a core of white matter. Three broad bands of nerve fibers, the inferior, middle, and superior cerebellar peduncles, connect it to the medulla, the pons, and the midbrain respectively. It has two hemispheres, one on each side of the central region (the vermis), and its surface is thrown into thin folds called folia. Within lie four pairs of nuclei.
The portion of the brain forming the largest segment of the rhombencephalon. It lies dorsal to the pons and medulla oblongata, overhanging the latter. It consists of two lateral cerebellar hemispheres and a narrow medial portion, the vermis. It is connected to the brainstem by three pairs of fiber bundles, the inferior, middle, and superior peduncles. The cerebellum is responsible for coordination of voluntary movements, the speed, trajectory, and stopping of movements, and for maintaining posture and balance. Sensory information to the cerebellum comes from the skeletal muscles and from inner ear receptors.
The part of the brain that controls balance and posture.
A part of the brain situated above the brainstem that controls balance and coordination of movement.
The area of the brain beneath the back part of the cerebrum.
Nestled within the intricate landscape of our brain, there resides a crucial domain dedicated to the coordination of movement, walking, and balance. This distinguished region, aptly known as the cerebellum, assumes a pivotal role in orchestrating the harmonious interplay of our physical motions, ensuring a seamless dance of coordination and equilibrium.
Located at the posterior part of the skull, behind the brainstem, the cerebellum is a brain region primarily responsible for the upkeep of posture and balance, as well as the coordination of movement.
The cerebellum is connected to the brainstem through thick nerve tracts and is composed of two hemispheres. Emerging from the inner side of each hemisphere are three nerve fiber stalks that establish connections with different regions of the brainstem, facilitating the transmission of signals between the cerebellum and the rest of the brain. These stalks give rise to nerve fibers that spread out towards the intricate folds of the cortex, the outer layer of each cerebellar hemisphere. This cortex comprises interconnected nerve cells, often referred to as gray matter.
Information regarding the body’s posture and the status of muscle contraction or relaxation is transmitted from muscle tendons and the inner ear’s labyrinth to the cerebellum via the brainstem. The cerebellum, in collaboration with the basal ganglia (clusters of nerve cells deep within the brain), utilizes this data to refine and optimize the messages relayed from the motor cortex in the cerebrum (the primary mass of the brain) to the muscles.
When the cerebellum is affected by disease or damage, it can lead to a condition known as cerebral ataxia. This condition is characterized by an unsteady, jerky gait, slurred speech, and other forms of uncoordinated movements throughout the body. Similarly, alcohol intoxication can impair cerebellar function and produce comparable symptoms.
