Final Flashcards
The cranial sutures of the temporal bones where they meet the parietal bones are?
Beveled, like the gills of a fish, indicating articular motility for a respiratory mechanism
Dr. William G. Sutherland state that dural membranes
Act as ‘guy wires’ (for the movement of the cranial bones, holding tension for the opposite motion
Dr. William G. Sutherland Used what to describe the three Cartesian axes held in reciprocal tension
Reciprocal tension membrane system (RTM)

What are Chakra’s?
Thresholds between the ordinary and non-ordinary consciousness
What does the Occipital bone articulate with?
Parietal bones superiorly at the lambdoid suture
Laterally with the mastoid portions of the temporal bones
Sphenoid anteriorly

12 bones
Sphenoid
Ethmoid
Two parietals
Two Nasal
Two maxillae
Two lacrimals

3 important things about the Sphenoid?
Cranial Keystone
Sphenoid movement, at the SBS, was central to motion of the entire craniosacral mechanism
Considered the “Dreaming Bone
What is the SBS (Sphenobasila Synchondrosis)
A fulcrum Base of the Sphenoid and the base of the occiput
What does the temporal bone articulate with
Parietal bone
Occiput
Sphenoid:Articulation extends out to the external surface at the pterion
Zygoma
Where does the Medial Pterygoid Muscle originate?
Deep head from the medial surface of the lateral pterygoid plate
Where does Medial Pterygoid Muscle insert?
The master muscle to form a common tendinous sling
Where does the lateral pterygoid muscle originate?
Upper/Superior head Greater wing of the sphenoid bone
Lower/Inferior head on the lateral surface of the lateral pterygoid plate
Where does the lateral pterygoid muscle Insert?
Neck of the condyloid process of the mandible
Upper/Superior head insert onto the articular disc and fibrous capsule of the TMJ
When does the primitive streak form?
Day 16
From the bottom up
What is Guzay’s Theorem
The atlantoaxial axis of rotation.
Acts as the primary joint for mandible motion (Mastication, chewing, biting, etc.)
What vertebrae moves with Guzay’s theoem
C1 (2)
How many hemispheres of the brain
2; Left and right
What is the Arachnoid?
What is superficial and what is deeper
It is interposed between the two other meninges
the more superficial and much thicker dura mater and the deeper pia mater
from which it is separated by the subarachnoid space. The delicate arachnoid layer is attached to the inside of the dura and surrounds the brain and spinal cord.
what does the Faux cerebrum do
Separates the two hemisphers
What is the cerebral cortex?
Folded structure; Brain
What are arachniod granulations?
projections of the arachnoid membrane (villi) into the dural sinuses that allow CSF entrance from the subarachnoid space into the venous system.
