How do you memorize the brainstem?
How do you memorize the brainstem?
The “Rule of M/S” helps to establish where the long tracts of the brainstem run: medially or laterally. This mnemonic requires some simple nomenclature gymnastics. The “M” in the rule stands for “medial”; the “S” stands for “side”, or lateral brainstem.
What are the 5 parts of the brainstem?
Components of the Brainstem Brainstem Anatomy: Structures of the brainstem are depicted on these diagrams, including the midbrain, pons, medulla, basilar artery, and vertebral arteries.
What are the 4 main parts of the brainstem?
The brainstem (brain stem) is the distal part of the brain that is made up of the midbrain, pons, and medulla oblongata.
What is the anatomy of 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 four sections in descending order: the diencephalon, midbrain, pons, and medulla oblongata.
How do you remember the medulla?
Helpful mnemonic: The medulla controls heartbeat and breathing. Helpful mnemonic: picture an Olympic athlete wearing gold medals around her neck and covering her heart and lungs.
What is brainstem syndrome?
Brainstem stroke syndromes are a subtype of strokes which lead to ischemia of the structures of the brainstem. The midbrain, pons, and medulla oblongata are components of the brainstem which control basic body functions such as consciousness, breathing, proprioception, heart rate, and blood pressure.
Where is the medulla located?
brainstem
medulla oblongata, also called medulla, the lowest part of the brain and the lowest portion of the brainstem. The medulla oblongata is connected by the pons to the midbrain and is continuous posteriorly with the spinal cord, with which it merges at the opening (foramen magnum) at the base of the skull.
What can happen if the brain stem is damaged?
A brain stem injury can cause dizziness or lack of motor function, with more severe cases resulting in paralysis, coma, or death. Treatment can be extremely expensive, and many victims are unable to work while coping with a brain stem injury.
What are the 3 parts of the brain stem?
The first two nerves originate in the cerebrum, and the remaining 10 cranial nerves emerge from the brainstem, which has three parts: the midbrain, the pons and the medulla.
What is the first part of the brainstem?
The first part of the brainstem we will consider is the midbrain. The midbrain (also known as the mesencephalon) is the most superior of the three regions of the brainstem. It acts as a conduit between the forebrain above and the pons and cerebellum below.
How are tracts and nuclei arranged in the brainstem?
The layout of tracts and nuclei varies from one level of the brainstem to the other. As a result, the cross-sectional layout of the nuclei and tracts within the medulla may be slightly different going from the decussation of the pyramids to the level of the olives, for example.
What is the most rostral component of the brainstem?
This is the most rostral component of the brainstem which is traversed by cerebral aqueduct that connects the third ventricle above to the fourth ventricle below. There is a small region of the midbrain that lies just posterior to the aqueduct and is known as the tectum.
What is the anatomy of the pons?
The pons develops from the embryonic metencephalon (part of the hindbrain, developed from the rhombencephalon), alongside the cerebellum. In this article, we will look at the anatomy of the pons – its location, structure and function, blood supply and clinical relevance.
