The Cerebrospinal Fluid is absorbed into the venous blood in the dural sinuses through the arachnoid villi. Arachnoid villi connect the subarachnoid space to the superior sagittal sinus.
dural venous sinuses
Answer: Arachnoid Villi
i think its the arachnoid villi
The answer that I have found is the Arachnoid Villi-Lucein
The fluid that is in the dural venous sinuses is venous blood that originates from the brain or cranial cavity. They collect blood from veins on the surface of the brain. Blood from the sinuses empties into the internal jugular veins
The air-filled paranasal sinuses and their mucous tissue linings help regulate the temperature and humidify the air breathed in, lighten the bone structure and weight of the skull, and give tone to the voice. It is not entirely clear what the skull's blood-filled cranial venous sinuses' full purposes are, but they do function to help the collection and return flow of venous blood and cerebrospinal fluid drainage from the tissues and veins in the cranium and back to the heart.
It drains leaked plasma back into the (venous) blood.
These vessels are called venous sinuses. They act as blood reservoirs and are part of the venous or return portion of the cardiovascular system.
Blood courses along veins back towards the heart. The veins have one way valves to prevent back flow. Venous blood from below the heart drains into the inferior vena cava. Venous blood from above the heart drains into the superior vena cava. These empty into the right atrium.
The superior sagittal sinus is an area above/behind the brain, which allows blood veins to span the area, from the top of the head towards the back. It is believed that the CSF drains through the arachnoid villi into the dural venous sinuses of the superior sagittal sinus. The CSF then drains into the internal jugular veins.
The dural venous sinus or venous sinus as it can be called is: - Formed by dura mater in the brain, - Also receives great veins which drain blood into them, - It also, receives cerebrospinal fluid (CSF) from the subarachnoid space which drain into them. - The dura mater which form the sinuses are unalterable in capacity (that is, inelastic). unlike The a Vein which: - Only receives venous tributaries - Do not receives CSF into them - is potentially able to alter its capacity
Thin-walled collections of blood, resembling blood blisters, found commonly in the ears and less often on the lips and on the face and neck of elderly sun-damaged men, discontinuous venous cavities or channels; Cf.: marginal sinuses of placenta. http://cancerweb.ncl.ac.uk/cgi-bin/omd?venous+lakes
Venous blood contains oxygen-poor blood.
Yes. If they are alive, they will have venous blood, which carries blood to the heart.
Within the brain, the cerebrospinal fluid circulates from the two lateral ventricles(in the cerebral hemispheres) into the third ventricle and then through the cerebral aqueduct of the midbrain into the fourth ventricle. From the fourth ventricle, some fluid continues down the central canal of the spinal cord, but the bulk of it circulates into the subarachnoid space via three openings in the walls of the fourth ventricle. the fluid returns to the blood in the dural sinuses via the arachnoid villi.
