Correctly label the following meninges and associated structures Arachnoid valus Arachnoid maler Meningeal layer of dura Pia mater Subarachnoid space Periosteal layer of dura Fabcccrobni
The correct answer and explanation is:
It seems you are trying to correctly label the meninges and associated structures from an image. Unfortunately, I cannot view or interpret the image directly from the provided link. However, I can guide you on how to label the structures based on common anatomical organization of the meninges and related layers.
Here are the typical layers of meninges and associated spaces (from superficial to deep):
- Periosteal layer of dura mater
- The outer layer of the dura mater, adhering to the inner surface of the skull.
- Meningeal layer of dura mater
- The inner layer of the dura mater, closely associated with the periosteal layer but separates to form dural sinuses in some areas.
- Arachnoid mater
- A delicate, web-like membrane beneath the dura mater.
- Subarachnoid space
- The space between the arachnoid mater and pia mater, containing cerebrospinal fluid (CSF) and blood vessels.
- Arachnoid villi (or granulations)
- Small protrusions of the arachnoid mater into the dural venous sinuses, facilitating CSF reabsorption into the venous system.
- Pia mater
- The innermost layer, adhering closely to the brain and spinal cord’s surface.
- Falx cerebri (Falccrobni, as mentioned)
- A sickle-shaped fold of the meningeal dura mater that descends into the longitudinal fissure between the cerebral hemispheres.
To label your diagram:
- Locate the outermost and innermost layers to identify the dura mater (periosteal and meningeal layers) and pia mater.
- Look for web-like structures and spaces beneath the dura mater for arachnoid mater and subarachnoid space.
- Find protrusions or projections near venous sinuses for arachnoid villi.
