Meninges is the collective term fro the three membranes covering the brain and spinal cord. The meninges are composed of the
1) Dura
mater is the layer of meninges closest to the skull resting on top of the arachnoid membrane attached to the skull in several pints, the dura
mater is made up of a fibrous material that protect the brain like tight-fitting
cap. Because it is attached to the skull the dura
mater also prevents the brain from moving within the skull.
2) Arachnoid mater spider web like layer. Rest between the pia
mater and the dura
mater. The arachnoid membrane covers the brain loosely, a bit like a hairnet, like the pia
mater it too is impermeable to fluids. The arachnoid membrane also consists of long filaments that attach it to the pia
mater. In between the arachnoid membrane and the pia
mater is an area called the subarachnoid
space, which contains cerebrospinal
fluid. Because the arachnoid membrane is impermeable to fluid, it prevents the cerebrospinal
fluid-- which helps protect the brain from trauma to the skull -- from escaping.
3) Pia mater is the membrane closest to the brain. It is a delicate layer that adheres to the brain. It is soft and thin, and covers the brain and spinal cord like a layer of glue, following every curve and contour of the brain. It is impermeable to fluid and laced with a network of small blood vessels called capillaries that supply blood to the brain and spinal cord.
^ What they are trying to say is -
From Superficial to deep the meninges and their related spaces are as follows:
1 - Dura
mater
2 - Subdural
space
3 - Arachnoid mater
4 - Subarachnoid
space
5- Pia mater
Your meninges are the most superficial tissues that surround your brain. The most superficial layer of the meninges is called Dura Mater.
The Dura Mater is the most superficial of the three spinal meninges.
Connective tissue membranes, which includes synovial membranes, meninges, fascia (superficial and deep fascia), fibrous pericardium, and perichondrium.
What is the opposite of deep
pia mater
Meninges consist of three layers. They are 1. The Dura mater 2. The Arachnoid mater 3. the Pia mater
The opposite of deep is superficial. A small paper cut is superficial.
Superficial
Superficial frostbite is only to the outer layers of the skin.
Skin is superficial to muscles. Superficial means above, while deep means below. So muscles are deep to skin and dermis is superficial to muscle tissue.
The most superficial part of the dermis is the papillary layer , the dermis is made up of papillary layer & Reticular layer and the papillary layer is just made up of loose connective tissue which allows movement to the epidermis and also contains capillaries and regulates the body temperature .
The Stratum Corneum is the most superficial layer of skin.
