OTM - Cranial Exam With Correct Answers 100% Verified
Motility - ANSWER -The ability to move spontaneously, to exhibit spontaneous motion
Mobility - ANSWER -Something movable, not stationary, or the capability of being moved
by an external force
Primary respiratory mechanism - ANSWER -Inherent motility of the brain and spinal cord
-Fluctuation of the CSF
-Mobility of the intracranial and intraspinal membranes
-Articular mobility of the cranial bones
-Involuntary mobility of the sacrum between ilia
Ethmoid - ANSWER -Only basicranial bone entirely of endochondral origin
Basicranium - ANSWER
Inferior portions of temporals, sphenoid, occipital bones, midline nasal septum
Sphenobasilar synchondrosis - ANSWER
Vault hold - ANSWER
Fingers contact greater wing of the Sphenoid, anterior to the tragus, mastoid region,
lateral occiput
-To observe transverse widening, direct attention to your PIP joints
Sphenoid bone articulation with temporal bone - ANSWER
,Functions of the sphenoid bone - ANSWER
Forms anterior middle and posterior cranial fossa
Part of the orbit
- Houses pituitary

-T primary synchondrosis of sphenobasilar synchondrosis***
Sphenoid composite motion -ANSWER-Physiological motion in horizontal axis through
center of body
-Inhalation phase = flexion
-Exhalation phase = extension
SBS During inhalation -ANSWER-bends (in response to pull of the reciprocal tension
membrane, falx and tentorium)
-Torsion in opposite direction from each other about parallel transverse axes from
occiput
-Greater wings move laterally, anteriorly, and inferiorly
-Angle between sphenoid and basiocciput becomes more acute
SBS during exhalation - ANSWER -Extends (relaxation of reciprocal tension membrane,
falx and tentorium)
-Rotates in opposite directions about parallel transverse axis from occiput
-Greater wings move superiorly, medially, and posteriorly
The Becker (base) hold - ANSWER -Fingers contact occiput and greater wing of the
sphenoid
-To observe transverse widening, direct attention to your thenar eminence
, Occipital composite functions - ANSWER -Forms posterior cranial fossa
-Supports brain stem
-Posterior attachment for reciprocal tension membrane
-Key articulations with SBS (parietals, temporals, sphenoid, atlas)
-Primary motion influence on temporal and sacrum
Occipital composite - ANSWER -Inion
-Sutures
-Basilar projection
-Condylar parts
-Basiocciput
-Jugular process
-Jugular foramen
-Tongue in groove harmonic
-Confluence of sinuses
-Hypoglossal canal
-Squamous portion
Fascia relations of the occipital bone - ANSWER -Midline dura (falx)
-Posterior dural septa (tent)

-Paravertebral fascia
Occipital composite physiological motion - ANSWER -Horizontal axis above jugular
process at the level of the sphenobasilar symphysis
Inhalation changes on coronal and sagittal sutures - ANSWER -Increased volume
