What is the medulla the middle of?
The medulla sits below the pons and above the spinal cord and is a major relay point for information going to and from your brain and spinal cord. In fact, its ‘middle-man’ position is actually reflected in its name, which means ‘elongated’ or ‘oblong’ (oblongata) ‘middle’ (medulla).
What is the main function of medulla?
The medulla oblongata plays a critical role in transmitting signals between the spinal cord and the higher parts of the brain and in controlling autonomic activities, such as heartbeat and respiration.
Which center is not found in medulla?
Note that the spinal accessory nucleus (CN XI) is located in the cervical spinal cord and not the medulla.
Why is the medulla important for our survival?
The medulla contains the nuclei that control vital (survival) functions: the respiratory and cardiovascular centres, swallowing, blood pressure and vomiting (Box 6.3). A key nucleus involved in these functions is the nucleus of the solitary tract (NTS).
What would happen if your medulla was damaged?
It plays an essential role in passing messages between your spinal cord and brain. It’s also essential for regulating your cardiovascular and respiratory systems. If your medulla oblongata becomes damaged, it can lead to respiratory failure, paralysis, or loss of sensation.
What arteries supply the medulla?
The blood supply of the medulla is derived from the two vertebral arteries. The midline anterior spinal artery, formed from the fusion of medial branches from each vertebral, supplies part of the central medulla (as well as much of the upper cervical cord).
What is this title midbrain pons and medulla?

What is medial medullary syndrome?
Medial Medullary Syndrome (Dejerine Syndrome): Caused by occlusion, or a blockage, in the vertebral or spinal artery, this condition results from a lack of blood blow through parts of the medulla causing paralysis in areas like the legs, arm, face, and possibly tongue.
What is the medulla oblongata?
Anatomy The medulla oblongata is one of the three parts of the brainstem, along with the midbrain and the pons. These three collaborating structures are located in front of the cerebellum at the base of the brain and connect to the spinal cord. 1
What is medial medullary syndrome (Dejerine syndrome)?
Medial medullary syndrome, also known as Déjerine syndrome, is secondary to thrombotic or embolic occlusion of small perforating branches from vertebral or proximal basilar artery supplying the medial aspect of medulla oblongata 1,2. Article: Epidemiology.
