What is the bridge of the brainstem?
The pons (Latin for “bridge”) is part of the brainstem that in humans and other bipeds lies inferior to the midbrain, superior to the medulla oblongata and anterior to the cerebellum. The pons is also called the pons Varolii (“bridge of Varolius”), after the Italian anatomist and surgeon Costanzo Varolio (1543–75).
What part of the brain is like a bridge?
The corpus callosum is, in essence, an information superhighway that carries a large volume of neural traffic across the brain. It is a thick bundle of nerve fibers that bridges the right and left halves of the brain.
What part of the brainstem contains the pyramids the cerebral peduncles literally means bridge?
The medulla oblongata contains the pyramids; the midbrain contains the cerebral peduncles; pons means “bridge.”
Which part of the brain is the bridge between the spinal cord and brain itself?
The word pons literally means “bridge,” and as the name suggests, the pons serves to connect the brain and spinal cord. It also is involved in regulating brain activity during sleep. The medulla, pons, and midbrain together are known as the brainstem.
Is the cerebellum part of the brainstem?
The cerebellum (which is Latin for “little brain”) is a major structure of the hindbrain that is located near the brainstem. This part of the brain is responsible for coordinating voluntary movements. It is also responsible for a number of functions including motor skills such as balance, coordination, and posture.
Why is pons called bridge?
Pons is Latin for “bridge”; the structure was given its name by the Italian anatomist Costanzo Varolio, who thought that the most conspicuous portion of the pons resembled a bridge that connected the two cerebellar hemispheres.
Which structure serves as a bridge between the brainstem and the medulla oblongata?
The pons serves as a bridge between the midbrain and the medulla oblongata. The pons also contains the nuclei and fibers of nerves that serve eye muscle control, facial muscle strength, and other functions. The medulla oblongata is the lowest part of the brainstem and is interconnected with the cervical spinal cord.
What is in the brain stem?
The brainstem is the structure that connects the cerebrum of the brain to the spinal cord and cerebellum. It is composed of 3 sections in descending order: the midbrain, pons, and medulla oblongata.
Which part of the brainstem contains the cerebellar peduncles?
The part of the brainstem above the pons is the mid-brain. Features of its dorsal surface are the upper part of the roof of the fourth ventricle, the superior cerebellar peduncles, these bulges, the inferior and superior colliculi, and in the mid-line the pineal body.
Which is the brain stem?
The brainstem (or brain stem) is the posterior stalk-like part of the brain that connects the cerebrum with the spinal cord. In the human brain the brainstem is composed of the midbrain, the pons, and the medulla oblongata….

Which part of the brain connects to the spinal cord?
The brain stem
The brain stem is a bundle of nerve tissue at the base of the brain. It connects the cerebrum and cerebellum to the spinal cord.
What are parts of brainstem?
The brainstem is divided into three sections in humans: the midbrain (mesencephalon), the pons (metencephalon), and the medulla oblongata (myelencephalon).
