ANATOMY AND PHYSIOLOGY OF THE
HEAD
What 3 distinct connective tissue membrane surrounds the brain? - CORRECT
ANSWERS-1. Dura Mater
2. Arachnoid
3. Pia Mater
Which of the 3 membranes of the meninges is formed by 2 double layer membranes? It
is also the strongest and outermost membrane? - CORRECT ANSWERS-Dura Mater.
Describe the 2 Dura Mater layers. - CORRECT ANSWERS-It is composed of 2 layers
called the Endosteum(Internal Periosteum) and the True Dura Mater/Meningeal Layer.
They are very close to eachother except when in the venous sinus.
The Endosteum layer is actually part of the? - CORRECT ANSWERS-It is part of the
calvaria and continuous with the external periosteum at the sutures and foramina.
What is the true Dura Mater continuous with? - CORRECT ANSWERS-It is continuous
with the Spinal Dura and provide tubular sheaths for the cranial nerves.
, What is the space below the Dura Mater? - CORRECT ANSWERS-The space below is
called the Subdural Space that contains enough fluid to keep the surface moist.
The Endosteum layer follows the Calvarium and the Tru Dura Mater follows the fissure
or Sulcus of the cerebrum and that separation forms the Venus Sinus. T/F - CORRECT
ANSWERS-T
What deoes the Dural Sinus provide? - CORRECT ANSWERS-They provide Venous
Drainage for the brain. Meningeal Arteries are also found in this space.
What 4 inward projecting folds that divide the cranial cavities into compartments of the
Dura Mater form? - CORRECT ANSWERS-The 3 extensions are the Falx Cerebri, Falx
Cerebelli, Tentorium Cerebelli and the Diaphragm Sellae(which forms a bridge over the
sellae Turcica and cover the hypophysis/Pituitary Gland).
Describe the Falx Cerebri? - CORRECT ANSWERS-The Falx Cerebri is a double fold
of Dura Mater that descends through the interhemispheric fissure in the midline of the
brain to seperate the cerebral hemispheres. It is relatively thin anteriorly where it
attaches to the Crista Galli of the ethmoid bone but is a broader posterior where it
attaches to the superior surface off the Tentorium Cerebelli inferiorly. It also attaches
superiorly to the midline of the cranium and also extends posteriorly to the attached to
internal Occipital Protuerance.
What does the Falx Cerebri Superior margin contain? - CORRECT ANSWERS-They
contain the Superior Sagittal Sinus (form the floor of the Superior Sagittal Sinus)
Describe which surface is inferiorly closely related to the Falx Cerebri? - CORRECT
ANSWERS-The Free edge between the attachments inferiorly closely related to the
superior surface of the Corpus Callosum and contains the Inferior Sagittal Sinus.
what is line of attachment called located between the Falx Cerebra and the Tentorium
Cerebelli - CORRECT ANSWERS-The Straight Sinus.
Describe the 3rd inward projection of the True Dura Mater. - CORRECT ANSWERS-It is
called the Tentorium Cerebelli. It is an extension of the Dura Mater the separates the
cerebellum from the inferior portion of the Occipital Lobes of the Cerebrum. It is also
elevated in the middle and declining downward toward the circumference, it covers the
superior surface of the Cerebellum and supports the Occipital Lobes of the Cerebrum.
What is to the middle line of the upper surface, posterior border of the Falx Cerebri? -
CORRECT ANSWERS-The Straight Sinus is being placed at their junction.
Where does the Tentorium Cerebelli attach to? - CORRECT ANSWERS-The
anterolateral attaches to the Temporal Bone. The anterior part attaches to the posterior
Clinoid Process. The posterolateral margin attaches to the edge of the Transverse Sulci
