What type of tissue is the medulla?
The medulla is a classical lymphoepithelial tissue like the thymus.
Is the medulla oblongata an organ?
We arrive at everyone’s favorite part of the brain, the medulla oblongata! 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.
What is the medulla oblongata made up of?
As part of the brainstem, the medulla oblongata helps transfer messages between parts of the brain and spinal cord. The medulla contains myelinated (white matter) and unmyelinated (grey matter) nerve fibers. Myelinated nerves are covered with a myelin sheath composed of lipids and proteins.
What is medulla oblongata and its function?
Your medulla oblongata is located at the base of your brain, where the brain stem connects the brain to your spinal cord. 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.
Is the medulla oblongata the brain stem?
Key takeaways. Your medulla oblongata is located at the base of your brain, where the brain stem connects the brain to your spinal cord. 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.
Is the medulla part of the brainstem?
The brainstem (or brain stem) is the posterior stalk-like part of the brain that connects the cerebrum with the spinal cord. In the human brain the brainstem is composed of the midbrain, the pons, and the medulla oblongata….

What fissure has the medulla oblongata?
anterior median fissure
The anterior median fissure contains a fold of pia mater, and extends along the length of the medulla oblongata. It ends at the lower border of the pons in a small triangular area, termed the foramen cecum. On either side of this fissure are raised areas termed the medullary pyramids.
What artery supplies the medulla?
Among the most important dorsal-lateral arteries (also called long circumferential arteries) are the posterior inferior cerebellar artery (PICA) and the anterior inferior cerebellar artery (AICA), which supply distinct regions of the medulla and pons.
Is the medulla oblongata voluntary or involuntary?
[edit on Wikidata] The medulla oblongata (or 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. Nov 18 2019
Does the medulla oblongata maintain homeostasis?
Medulla Oblongata Important role in maintain homeostasis, as it is an autonomic reflex center housing important visceral motor nuclei (ex. cardiovascular and respiratory centers. Diencephalon
Is the medulla located in the hind brain?
The medulla oblongata is located in the brain stem, anterior to (in front of) the cerebellum. This is a cone-shaped, neuronal (nerve cell) mass in the hindbrain, which controls a number of autonomic (involuntary) functions. This section of the brain helps transfer messages to the spinal cord and the thalamus, which is in the brain, from the body.
Does medulla oblongata control reflexes?
It regulates heart rate, blood pressure, respiratory rate, and other life-sustaining processes that take place without a person having to actively think about them. The medulla also controls involuntary reflexes such as swallowing, sneezing, and gagging. Another major function is the coordination of voluntary actions such as eye movement.
