what's another name for medulla oblongata?

The medulla oblongata or simply medulla is a long stem-like structure which makes up part of the brainstem. It is anterior and partially inferior to the cerebellum. It is a cone-shaped neuronal mass responsible for autonomic (involuntary) functions ranging from vomiting to sneezing.

what is the function of medulla oblongata? The medulla oblongata helps regulate breathing, heart and blood vessel function, digestion, sneezing, and swallowing. This part of the brain is a center for respiration and circulation. Sensory and motor neurons (nerve cells) from the forebrain and midbrain travel through the medulla.

how do you spell oblongata?

noun, plural ob·long·a·tas, ob·long·a·tae [ob-lawng-gah-tee, -long-] . medulla oblongata.

What does Pons mean in medical terms?

Medical Definition of Pons Pons: A specific section of the brain formed by the rounded prominence on the front surface of the brainstem. (The brainstem is the lowest part of the brain that merges with the spinal cord; it consists of a structure called the medulla oblongata, the midbrain and the pons.)

What is another name for medulla?

A medulla (/m?ˈd?l?/, /m?ˈduːl?/; plural medullas or medullae) is the middle of something. The word came to English and ISV from Latin, where it means marrow (and came from medius, middle). Its anatomical uses include: Medulla oblongata, a part of the brain stem. Medulla spinalis, an alternative name for the spinal

What structure derives from the embryonic Myelencephalon?

What structure derives from the embryonic Myelencephalon? ||| The myelencephalon or afterbrain is the most posterior region of the embryonic hindbrain, from which the medulla oblongata develops.

What is medulla?

The medulla oblongata, also known as the medulla, directly controls certain ANS responses, such as heart rate, breathing, blood vessel dilation, digestion, sneezing, swallowing and vomiting. It is a portion of the brainstem, located just below the pons and just above the spinal cord.

What does medulla mean in medical terms?

Medical Definition of Medulla Medulla: The innermost part. For example, the adrenal medulla is the innermost part of the adrenal gland, the renal medulla is the inner part of the kidney, and the spinal medulla is the part of the spinal cord that is lodged deep within the vertebral canal.

What's the most important part of the brain?

Brain Stem: The medulla is easily the most important part of the brain. We would not be able to live without the medulla because of the crucial task it performs including regulating blood pressure and breathing. As part of the brain stem, it also helps transfer neural messages from the brain to the spinal cord.

What will happen if medulla is damaged?

The medulla oblongata connects our brain and our spinal cord with most of our sensory and motor fibres either crossing into the brain or finishing at this level (Farrell & Dempsey 2013). Damage to the medulla oblongata can result in: Difficulty swallowing. Loss of gag and cough reflex.

What part of the brain could you live without?

Some other extreme cases include hydranencephaly, where the entire cerebral portion is missing and all that’s present is the brainstem. Moreover, there are nine documented cases of people living without a cerebellum, the part of the brain that controls voluntary movement.

Is medulla oblongata an organ?

Is medulla oblongata an organ? ||| Being a part of the brainstem, the medulla oblongata is essential to communications between the peripheral and central nervous systems as nearly all neuronal signals are sent through this organ.
