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 is the medical term meaning inflammation of the meninges?
The inflammation of the meninges, brain and the spinal cord is meningoencephalomyelitis. Mening/o-meninges encephal/o-brain; Myel/o-spinal cord/ bone marrow; itis-inflammtion. Meningitis is inflammation of the only the meninges, which are the covering of the brain and spinal cord. Meningitis does not encompass the spinal cord and brain.
What are the meningeal layers of the CNS?
what are the three layers of the meningeal layers that surround the central nervous system
Structures that form an enclosure for the spinal cord?
The boney structures are the Vertebral Foramina. The spine is "divided" into the Cervical Spine (neck), the Thoracic Spine (chest & Ribs), Lumbar spine (lower back) anc Coccyx, or "tailbone".
What cranial nerve covers meninges?
The Optic Nerve (one of the Cranial Nerves) is enclosed by three sheaths that are continuous with the three layers of cranial meninges (dura, arachnoid, and pia). The central artery and vein of the retina pass through these meningeal sheaths and are included in the distal part of the optic nerve.
Which of the three meningeal layers forms the dural venous sinuses?
The innermost membrane, the pia mater, consists mainly of small blood vessels and is the most vascular of the three meninges.
What is brain tuberculosis called?
Yes, it is. Tuberculosis (TB) is a contagious, airborne disease that typically affects the lungs. TB is caused by a bacterium. If the infection is not treated quickly, the bacteria can travel through the bloodstream to infect other organs and tissues. Sometimes, the bacteria will travel to the meninges, which are the membranes surrounding the brain and spinal cord. Infected meninges can result in a life-threatening condition known as meningeal tuberculosis. Meningeal tuberculosis is also known as tubercular meningitis or TB meningitis.
What are the protective layers around the brain and spinal cord?
Pia Mater, Subarachnoid Space, Arachnoid Mater, Dura Mater, Crainum/Vertebral Bodies.
What happens if the meninges and infected?
it will not actually function well..then it may cause dead :)
What does extradural mean?
You have the meninges to cover the brain and spinal cord. Meninges composed of three layers. Outer most is tough and called as dura matter. Extradural means between the dura matter and the skull. Typically the middle meningeal artery brakes to give you that extradural hematoma. It is also called as epidural hematoma. The British spell it as haematoma. The US should spell it as hematoma, I guess.
What is the cobweb like structure in the middle meningeal layer?
Spiderweb-like (hence the name) arachnoid layer is one of the three meninges, the membranes that cover the brain and spinal cord. It is interposed between the two other meninges, the more superficial dura mater and the deeper pia mater, and is separated from the pia mater by the subarachnoid space.Arachnoid mater
What is the rough thick leathery meningeal layer called?
The dura mater, is the outermost of the three layers of the meninges surrounding the brain and spinal cord. The other two meningeal layers are the pia mater and the arachnoid mater. The dura surrounds the brain and the spinal cord and is responsible for keeping in the cerebrospinal fluid. The name "dura mater" is derived from the Latin "hard mother"[1], and is also referred to by the term "pachymeninx" (plural "pachymeninges").[2] The dura has been described as "tough and inflexible" and "leather-like".http://en.wikipedia.org/wiki/Dura_materThe pia mater (pronounced /ˈpaɪ.ə ˈmeɪtər/, from Latin "tender mother") is the delicate innermost layer of the meninges-the membranes surrounding the brain and spinal cord. The thin, mesh-like pia mater closely envelops the entire surface of the brain, running down into the fissures of the cortexpia mater.http://en.wikipedia.org/wiki/Pia_mater
