Brainstem Alternative Title: brain stem Brainstem, area at the base of the brain that lies between the deep structures of the cerebral hemispheres and the cervical spinal cord. The brainstem is divided into three sections in humans: the midbrain (mesencephalon), the pons (metencephalon), and the medulla oblongata (myelencephalon). The brainstem is a sort of automatic control centre for several important involuntary actions of the body, such as heartbeat, breathing, blood pressure, and many reflexes.

Brain Stem Injury Recovery & Rehabilitation The term brainstem refers to a composite substructure of the brain. It includes the midbrain, the pons and the medulla. It may also include the cerebellum and parts of the interbrain. Injury to the brain stem is so severe because it is similar to the motherboard of a computer being disrupted or destroyed.

Anatomy of the Brain Protected within the skull, the brain is composed of the cerebrum, cerebellum, and brainstem. The brainstem acts as a relay center connecting the cerebrum and cerebellum to the spinal cord. The brain receives information through our five senses: sight, smell, touch, taste, and hearing - often many at one time.

- Brainstem death. Brainstem death is a clinical syndrome defined by the absence of reflexes with pathways through the brainstem—the “stalk” of the brain, which connects the spinal cord to the mid-brain, cerebellum and cerebral hemispheres—in a deeply comatose, ventilator-dependent patient.

Cranial nerves Cranial Nerves. Cranial nerves are the nerves that emerge directly from the brain (including the brainstem), in contrast to spinal nerves (which emerge from segments of the spinal cord). Cranial nerves relay information between the brain and parts of the body, primarily to and from regions of the head and neck.

Brainstem In the human brain the brainstem includes the midbrain, the pons, and the medulla oblongata. Sometimes the diencephalon, the caudal part of the forebrain, is included. The brainstem provides the main motor and sensory innervation to the face and neck via the cranial nerves. Of the twelve pairs of cranial nerves, ten pairs come from the brainstem. Though small, this is an extremely important part of the brain as the nerve connections of the motor and sensory systems from the main part of the brain to the rest of the body pass through the brainstem.

Brainstem The medulla oblongata often just referred to as the medulla, is the lower half of the brainstem continuous with the spinal cord. Its upper part is continuous with the pons. The medulla contains the cardiac, respiratory, vomiting and vasomotor centres dealing with heart rate, breathing and blood pressure.

Brainstem Gliomas Practice Essentials. Brainstem gliomas are tumors that occur in the region of the brain between the aqueduct of Sylvius and the fourth ventricle. Brainstem gliomas account for approximately 10-20% of all childhood brain tumors. The incidence in adults is lower than that in children younger than 16 years.

Pons For other uses, see Pons (disambiguation). The pons is part of the brainstem, and in humans and other bipeds lies between the midbrain (above) and the medulla oblongata (below) and in front of the cerebellum. The pons is also called the pons Varolii (bridge of Varolius), after the Italian anatomist and surgeon Costanzo Varolio (1543–75).
