The collection of blood within the meningeal layers refers to a hematoma, which can occur in the space between the meninges—specifically, the dura mater, arachnoid mater, and pia mater—surrounding the brain and spinal cord. There are different types of hematomas, such as epidural and subdural hematomas, depending on their location relative to the dura mater. These collections of blood can result from trauma, such as head injuries, and can lead to increased intracranial pressure and neurological complications if not treated promptly.

What is the medical term meaning Collection of blood within the meningeal layers?
A subdural hematoma is a collection of blood in the space between the outer layer (dura) and middle layers of the covering of the brain (the meninges). It is most often caused by torn, bleeding veins on the inside of the dura as a result of a blow to the head.The meninges are layers or covers of the brain.There are 3 meninges but only 2 ways which blood can collect: EPIDURAL, SUBDURAL, SUBARACHNOID.Dr. evans onyango
What branch of a spinal nerve supplies the vertebrae and blood vessels of the spinal cord?
meningeal branch
What is the blood supply of arachnoid mater?
The middle meningeal artery supplies most of the blood for the dura mater, though the meningeal branches of the posterior and anterior ethmoidal artery also contribute.
What blood sample needs to be run within 15 minutes of collection?
The blood sample that needs to be run within 15 minutes of collection is a lactate sample. This is because lactate levels in the blood can rapidly change after collection due to ongoing cellular metabolism, so timely analysis is important for accurate results.
Which of the three meningeal layers forms the dural venous sinuses?
The dura mater forms the dural venous sinuses, which are venous channels located between the layers of the dura mater in the brain. These sinuses are important structures for draining blood and cerebrospinal fluid from the brain.
Which meningeal layer is the thickest and strongest?
The thickest and strongest meningeal layer is the dura mater. It is composed of dense connective tissue and serves as a protective barrier for the brain and spinal cord. The dura mater also plays a role in anchoring the brain within the skull and contains structures such as blood vessels and venous sinuses. Its resilience helps protect the central nervous system from injury.
Do the meningeal branch of a spinal nerve actually reenters the vertebral canal to innervate the meninges and blood vessels?
yes. true
What are three layers within the femur?
the three layers are.... compact bone spongy bone bone marrow
What sample needs to be run within 15 minutes of collection?
Arterial blood gas. It checks blood gas levels (oxygen, carbon dioxode, and bicarbonate) and blood pH.
What blood collection tubes is most appropriate for the collection of blood for a DIFF?
Lavender
Where are Dural venous sinuses found?
Dural venous sinuses are found between the periosteal and meningeal layers of the dura mater, which is the outermost layer of the meninges surrounding the brain. These sinuses drain blood and cerebrospinal fluid from the brain and ultimately connect to the internal jugular vein.
What is the medical terminology breakdown for hemarthrosis?
