THE MENINGES
Duramater
Arachnoid mater
Piamater
Character
Duramater
Arachnoid mater
Pia mater
Etmology
Dura -> Hard mother
Arachnoid -> Cobweb like
Pia -> Soft mother
Layers
Endosteal layer:
- Cranial venous sinuses are present between these two layers
Meningeal layer:
Folds:
Character
Falx cerebri
Falx cerebelli
Tentorium cerebelli
Diaphragma sellae
Shape
Sickle-shaped
Small sickle-shaped
Tent-shaped
Small horizontal fold
Functions
Separates the right from left cerebral hemisphere
Partly separates the cerebellar hemispheres
  1. Separates the cerebral hemispheres from hindbrain and lower part of midbrain
  2. Lifts off the weight of occipital lobes from the cerebellum.
Venous sinuses enclosed
  1. Superior sagittal sinus
  2. Inferior sagittal sinus
  3. Straight sinus
Occipital sinus
  1. Transverse sinuses
  2. Superior petrosal sinuses
Anterior and posterior intercavernous sinuses
Location
Just beneath the skull
Below the Duramater
Below the Arachnoid mater, covering the brain
Spaces
Epidural space: Space just above the duramater (Between Skull and Duramater)
Subdural space: Space below the duramater (Between duramater and arachnoid mater)
Subarachnoid space:
  • Space just below the arachnoid mater. (Between Arachnoid and Pia mater)
  • CSF (Cerebrospinal fluid) flows through Subarachnoid space.
No spaces
