The atria of the heart are separated from the ventricles by an area called coronary groove (sulcus). This contains the trunks of the coronary arteries which bring oxygenated blood to the heart muscles. On the back surface of the heart, the coronary sulcus contains the coronary sinus which receives venous blood from the heart muscles.
What else can I help you with?
What are the folds in the cerebral cortex called?
The folds in the cerebral cortex are called sulci (singular: sulcus) and gyri (singular: gyrus). Sulci are the grooves or furrows, while gyri are the ridges or bumps on the brain's surface. These folds increase the surface area of the brain, allowing for more neurons to be packed within the limited space of the skull.
What term is used to indicate the cerebrum's grooves?
The term used to indicate the cerebrum's grooves is "sulci."
What is the difference between a fissure and a sulcus?
A fissure is a deep groove or cleft, while a sulcus is a shallower groove. Fissures are usually larger and more prominent than sulci. In the brain, fissures are deeper grooves that divide the brain into lobes, while sulci are smaller grooves found within the lobes.
When did Battle of Sulci happen?
Battle of Sulci happened in -258.
What is the plurals form of sulcus?
Sulci is the plural of sulcus
What are the valleys separating the convolutions on the surface of the cerebrum?
The valleys separating the convolutions on the surface of the cerebrum are called sulci. They play a role in increasing the surface area of the brain, allowing for more neural connections and processing power within a limited space.
What do the atrioventicular valves prevent?
They prevent blood from backing up, or going backwards, into the atria.
Where is the atrioventicular node located?
It is located in the wall of the right atrium near the tricuspid valve.
What is the name given to the valleys on the surface of the cerebral cortex?
The name given to the valleys on the surface of the cerebral cortex is "sulci," while the raised ridges are called "gyri." These folds increase the surface area of the brain, allowing for more neurons and synapses to fit within the skull.
Can you increase the brain sulci?
No, not at all.
What does effacement of sulci mean?
As the ventricles enlarge with CSF under pressure, the brain is squeezed with the result that the gyri come together…emptying the subarachnoid spaces (sulci) of CSF. Refers to condition of not being able to visualize sulci on CT.
The convolutions on the cerebrum's surface is called?
The convolutions on the cerebrum's surface are called gyri and sulci. Gyri are the raised folds, while sulci are the grooves that separate them. These convolutions increase the surface area of the brain, allowing for more neurons to be packed within the limited space of the skull.
