The superior sagittal sinus (also known as the superior longitudinal sinus), within the human head, is an unpaired area along the attached margin of the falx cerebri. It allows blood to drain from the lateral aspects of anterior cerebral hemispheres to the confluence of sinuses.
What is the function of inferior sagittal sinus?
The inferior sagittal sinus (also known as inferior longitudinal sinus), within the human head, is an area beneath the brain which allows blood to drain outwards posteriorly from the center of the head.
What is inferior sagittal sinus?
The inferior sagittal sinus is one of the dural venous sinuses and runs along the inferior (free) edge of the falx cerebri 1. It runs from anterior to posterior, the same as the superior sagittal sinus, and drains into the straight sinus.
How many sagittal sinus are there?
2 Here, the straight, superior, and inferior sagittal sinuses come together in an area called the confluence of sinuses, which drains into the left and right transverse sinuses, through the sigmoid sinus, and on to the internal jugular vein.
What are brain sinuses?
The dural venous sinuses (also called dural sinuses, cerebral sinuses, or cranial sinuses) are venous channels found between the endosteal and meningeal layers of dura mater in the brain.
What drains to the inferior sagittal sinus?
The inferior sagittal sinus is formed within the free edge of the falx cerebri by the confluence of veins draining the falx cerebri and empties into the straight sinus. The sphenoparietal sinus connects both to the cavernous sinus and to the superior sagittal sinus.
What is the location of inferior sagittal sinus?
falx
The inferior sagittal sinus is one of the dural venous sinuses and runs along the inferior (free) edge of the falx cerebri 1. It runs from anterior to posterior, the same as the superior sagittal sinus, and drains into the straight sinus.
How transverse sinus is formed?
The transverse sinuses are formed by the tentorium cerebelli and drain into the right and left sigmoid sinuses. The transverse sinuses (left and right lateral sinuses), within the human head, are two areas beneath the brain which allow blood to drain from the back of the head.
What is the lateral wall of the nasal cavity called?
The lateral wall of the nasal cavity is a region of the nasopharynx essential for humidifying and filtering the air we breathe in nasally. Here we can find a structure called agger nasi.
What do you need to know about the nasal cavity?
The Anatomy of the Nasal Cavity 1 Anatomy. The inside of the nose including the bones, cartilage and other tissue, blood vessels and nerves all the way back posteriorly to the nasopharynx is called the nasal cavity. 2 Function. 3 Associated Conditions. 4 Tests.
What are the bones that make up the nasal septum?
The nasal septum is a piece of cartilage that separates the left and right nares. It runs vertically from the vomer bone to the ethmoid bone . There are 12 bones that contribute to the structure of the nasal cavity. They are the nasal bone, maxilla, sphenoid, vomer, palatine, lacrimal, and ethmoid bones.
Where are the turbinates located in the nasal cavity?
Inside the nasal cavity are three curved shelves of bone called turbinates or nasal conchae. They project from the lateral walls of the cavity and are called the superior, middle and inferior turbinates. The space between the turbinates is called the meatus.
