Parietal
What makes up the posterior cranial fossa
Primarily by the occipital bone with
Contributions from the temporal and parietal bones
Superior facets of cervical spine face
Back, Up, medial,
Directions of facets of atlas
Upwards (like little cups a ball can fit into)
Anterior longitudinal ligament becomes ____ at foramen magnum
Anterior Atlanto-occipito ligament
Posterior longitudinal ligament end where and becomes what
Ends at Atlantoaxial joint and becomes the tectorial membrane
What joint dictates Fryettes mechanics in the cervical spine
Uncovertebral joints (joints of Luschka)
Occipitoatlanto joint has what type of motion mechanics
Fryette type 1

Axis on C3
C7 on T1
T12 on L1
L5 on S1
What kind of joint is the hyoid bone
synsarchosis : held 100% by muscle, can be considered a sesamoid bone

Jugular notch of sternum
Roof of the anterior triangle of the neck
Platysma & deep cervical fascia
Floor of the anterior triangle of the neck
Prevertebral fascia covering deeper muscles
What is the Bregma
Junction of the coronal and sagittal sutures.
Represents the site of the anterior fontanelle in infants.
What is the inion
The most prominent point of the external occipital protuberance.
What is the Sella turcica
Saddle-shaped depression in the sphenoid bone that houses the pituitary gland.
The occipital-atlanto joint is what type of joint
Condylar diarthrosis
Atlanto-axial joint is what type of joint
Pivot diarthrosis
Anterior fontanelle
Largest
Lies at junction of frontal, Sagittal and coronal sutures
Posterior fontanelle
Lies at junction of lambdoid and sagittal sutures
Sphenoidal fontanelle
Lies at junction of squamous and coronal sutures
Mastoid fontanelle
Lies at junction of squamous and lambdoid sutures
