Is the medulla and the brain stem the same?
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 is the function of the medulla oblongata of the brainstem?
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.
What are the parts of the brain stem?
The brainstem is divided into three sections in humans: the midbrain (mesencephalon), the pons (metencephalon), and the medulla oblongata (myelencephalon).
What does brain stem do?
The brain stem is the lower part of the brain that’s connected to the spinal cord (part of the central nervous system in the spinal column). The brain stem is responsible for regulating most of the body’s automatic functions that are essential for life. These include: breathing.
Can you live without a medulla?
Your medulla oblongata makes up just 0.5% of the total weight of your brain, but it plays a vital role in regulating those involuntary processes. Without this vital section of your brain, your body and brain wouldn’t be able to communicate with each other.
How does the medulla affect behavior?
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.
Can a brain stem injury heal?
The brain stem is home to the most basic life functions, and the resulting damage can be devastating. However, it is possible for a person with a brain stem injury to at least partially recover by using the brain’s natural plasticity.
How far down does the brain stem go?
Anatomy. The brain stem is a tube-shaped mass of nervous tissue a little over 3 inches (8 cm) long. It is located at the base of the brain, superior to the spinal cord and inferior to the cerebrum.
What is the function of the medulla in the brain?
The medulla oblongata is a portion of the hindbrain that controls autonomic functions such as breathing, digestion, heart and blood vessel function, swallowing, and sneezing.
What is the lower part of the brain stem?
The medulla is the lowest part of the stem, and just above it is the pons , which is the characteristic bulge of the brain stem. Its main roles are to relay sensory information between the cerebellum and the cerebrum (the bulk of the brain), help regulate respiration,…
What is the structure of the brain stem?
The brain stem refers to the area of the brain between the thalamus and spinal cord. Structures of the brain stem include the pons, medulla oblongta, tectum, reticular formation and tegmentum. The brain stem is important for maintaining basic life functions such as breathing, heart rate and blood pressure.
What does the medulla do?
The medulla oblongata is a structure in the brain that transfers nerve messages from the brain to the spinal cord. In addition to connecting sensory and motor messages, it is responsible for many vital involuntary functions including regulating blood pressure, adjusting your heart function, pacing your rate of breathing and coordinating swallowing.
