The medulla oblongata (myelencephalon) is the lower half of the brainstem continuous with the spinal cord. Its upper part is continuous with the pons. The medulla contains the cardiac, respiratory, vomiting, and vasomotor centers regulating heart rate, breathing, and blood pressure.The medulla contains the cardiac, respiratory, vomiting, and vasomotor centers and regulates autonomic, involuntary functions such as breathing, heart rate, and blood pressure.The cardiac, vasomotor, and respiratory centers are found in: the medulla oblongata.

What does the medulla contain?
It contains nerve fibers and nerve cells covered by myelin, a substance that gives the tissue its white color, protects it, and speeds electrical signals. The medulla oblongata is divided into two parts: Superior section (upper, open part)
What are the three regions of the cerebrum?
Physiology. The cerebral cortex provides most of the functions of the cerebrum and is organized into three major regions: sensory, association, and motor areas.
In which area of the brain is the cardiac center located?
The medulla oblongata, specifically the medullary cardiovascular center (Fig. 8.1, inset), is the primary site of cardiovascular and baroreflex integration.
Where is medulla located in brain?
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.
Where are the cardiac vasomotor?
The correct answer is option A because the cardiac, vasomotor, and respiratory centers are located in the medulla oblongata within the brain stem….

Vasomotor center – Wikipedia
The vasomotor center (VMC) is a portion of the medulla oblongata. Together with the cardiovascular center and respiratory center, it regulates blood pressure.
What is located between pons and diencephalon?
The midbrain serves as the connection between the pons and the diencephalon. It also connects posteriorly to the cerebellum via the superior cerebellar peduncles. The anterior part of the midbrain contains the crus cerebri with the interpeduncular fossa located between them.
What is located just above the brainstem?
Located above the brainstem, the thalamus processes and transmits movement and sensory information.
What is pons function?
The pons, while involved in the regulation of functions carried out by the cranial nerves it houses, works together with the medulla oblongata to serve an especially critical role in generating the respiratory rhythm of breathing. Active functioning of the pons may also be fundamental to rapid eye movement (REM) sleep.
Where are pons located?
Where is the pons? The pons is a major division of the brainstem. It is found above the medulla and below the midbrain, and is anterior to (in front of) the cerebellum.
What is thalamus function?
Your thalamus is your body’s information relay station. All information from your body’s senses (except smell) must be processed through your thalamus before being sent to your brain’s cerebral cortex for interpretation. Your thalamus also plays a role in sleep, wakefulness, consciousness, learning and memory.

What are the 4 lobes of the brain and the function of each?
The four lobes of the brain are the frontal, parietal, temporal, and occipital lobes (Figure 2). The frontal lobe is located in the forward part of the brain, extending back to a fissure known as the central sulcus. The frontal lobe is involved in reasoning, motor control, emotion, and language.
What are the 4 lobes of the brain and their function?
Each side of your brain contains four lobes. The frontal lobe is important for cognitive functions and control of voluntary movement or activity. The parietal lobe processes information about temperature, taste, touch and movement, while the occipital lobe is primarily responsible for vision.
What is the hippocampus?
Hippocampus is a complex brain structure embedded deep into temporal lobe. It has a major role in learning and memory. It is a plastic and vulnerable structure that gets damaged by a variety of stimuli. Studies have shown that it also gets affected in a variety of neurological and psychiatric disorders.
Is the cardiac center located in the pons?
The correct answer is d.
The cardiovascular center is located in the medulla oblongata.
What are the two cardiac centers?
Cardioaccelerator and cardioinhibitory areas are components of the paired cardiac centers located in the medulla oblongata of the brain. They innervate the heart via sympathetic cardiac nerves that increase cardiac activity and vagus (parasympathetic) nerves that slow cardiac activity.
Which part of the brain controls blood pressure heart rate and respiration?
The brain stem sits beneath your cerebrum in front of your cerebellum. It connects the brain to the spinal cord and controls automatic functions such as breathing, digestion, heart rate and blood pressure.
What is the center of your brain called?
Brainstem. The brainstem (middle of brain) connects the cerebrum with the spinal cord. The brainstem includes the midbrain, the pons and the medulla.
What is the midbrain?
The midbrain is the topmost part of the brainstem, the connection central between the brain and the spinal cord. There are three main parts of the midbrain – the colliculi, the tegmentum, and the cerebral peduncles.
What is the function of pons in hindbrain?
Pons. The pons gets its name from the Latin word for ‘bridge’, and it connects the rest of the brainstem to the cerebral cortex. Bulbous in shape, it sits right underneath the midbrain and serves as a coordination centre for signals and communications that flow between the two brain hemispheres and the spinal cord.
What is in frontal lobe?
The frontal lobe is the most anterior (front) part of the brain. It extends from the area behind the forehead back to the precentral gyrus. As a whole, the frontal lobe is responsible for higher cognitive functions such as memory, emotions, impulse control, problem solving, social interaction, and motor function.

What are the three parts of the brainstem and their functions?
- Midbrain: The top part of the brainstem is crucial for regulating eye movements.
- Pons: The middle portion of the brainstem coordinates facial movements, hearing and balance.
- Medulla oblongata: The bottom part of the brainstem helps regulate your breathing, heart rhythms, blood pressure and swallowing.
What are parts of brainstem?
The brainstem is divided into three sections in humans: the midbrain (mesencephalon), the pons (metencephalon), and the medulla oblongata (myelencephalon).
