The brain stem is the area of the brain that connects the brain to the spinal cord. It consists of the midbrain, medulla, and bridge. Motor and sensory neurons travel through the brainstem to allow signals to be transmitted between the brain and the spinal cord. Most cranial nerves are in the brainstem. Read below for brainstem function.



The brainstem coordinates engine control signals sent from the brain to the body. This region of the brain also controls the life supporting the autonomic functions of the peripheral nervous system.


The fourth cerebral ventricle is located in the brainstem, posterior to the bridge and the medulla. This chamber filled with cerebrospinal fluid is continuous with the brain aqueduct and the central channel of the spinal cord.

The brainstem function controls several important functions of the body, including:

Control of blood pressure,


Other autonomic brainstem function

Information on relays between peripheral nerves and the spinal cord and upper parts of the brain. In addition to connecting the brain and the spinal cord, the brainstem also connects the brain with the cerebellum. The cerebellum is important for the regulation of functions such as the coordination of movements, balance, balance and muscle tension.


It is located above the brainstem and under the occipital lobes of the cerebral cortex. Nerve patterns that travel through the brainstem relay signals from the cerebellum to the areas of the cerebral cortex that are involved in motor control. This allows the coordination of minor motor motions needed during activities such as walking or playing video games.

The direction of the brain stem is at the junction of the brain and spine. It is earlier than the cerebellum.


Brain structures

The brain stem consists of the midbrain and part of the back of the brain, in particular of the sternum and the cord. The main function of the midbrain is to connect the three main areas of the brain: forebrain, midbrain, and hindbrain.


The main midbrain structures include the tectum and cerebral stalk. Tectum consists of rounded convexities of the brain matter that are involved in visual and auditory reflexes. The peduncle consists of large bundles of nerve fibers that connect the forebrain to the posterior brain.


The sacral muscle consists of two sub-regions called pulp and grinder because Metencalon consists of bridges and cerebellum. Pons helps in regulating breathing, as well as sleep and arousal states. The cerebellum transmits information between the muscles and the brain.


Mieleniec consists of the core oblongata and the function of connecting the spinal cord with the higher areas of the brain. Medulla also helps regulate autonomic functions, such as breathing and blood pressure.



Brain injury

Damage to the brain stem caused by injury or stroke can lead to difficulties with mobility and motor coordination. Activities such as walking, writing, and eating become difficult and a person may need lifelong treatment.   A stroke can cause breathing problems, heart rate, hearing, and speech. It can also cause hand and leg contusion as well as numbness in the body or on one side of the body.
