Cards

Term
CRANIAL SUTURES
Definition
articulation b/w cranial bones, synarthrodial
Term
ATLANTOOCCIPITAL (A/O) JOINT
Definition
articulation b/w atlas and occipital bone, plane, synovial
Term
ATLANTOAXIAL (A/A) JOINT
Definition
articulation b/w atlas and axis
Term
ATLANTO-ODONTOID JOINT
Definition
articulation b/w dens of axis and anterior arch of atlas, pivot
Term
FACET JOINT
Definition
articulation b/w inferior articulating facet of vertebra above and superior articulating facet of the vertebra below, plane, synovial
Term
INTERVERTEBRAL JOINT
Definition
articulation b/w intervertebral disc, amphiarthrodial
Term
ALAR LIGAMENT
Definition
run obliquely upward and lateral from the dens to the occipital condyles; limits rotation of the head of at atlas on axis, limits lateral flexion
Term
CUNIFORM LIGAMENT
Definition
composed of superior longitudinal fibers, transverse ligament, inferior longitudinal fibers
Term
INNER PORTION OF INTERVERTEBRAL DISC
Definition
nucleus pulposus
Term
OUTER PORTION OF INTERVERTEBRAL DISC
Definition
annulus fibrosus
Term
SUPERIOR LONGITUDINAL FIBERS
Definition
connects transverse ligament to the occiput
Term
TRANSVERSE LIGAMENT
Definition
stretches across the ring of atlas in the transverse plane; holds the dens against the anterior arch of atlas to create pivot joint
Term
INFERIOR LONGITUDINAL FIBERS
Definition
connects the transverse ligament to the axis
Term
ANTERIOR LONGITUDINAL (ALL)
Definition
runs vertically along the anterior surface of bodies of the vertebrae from the occiput to the sacrum; limits vertebral extension
Term
POSTERIOR LONGITUDINAL (PLL)
Definition
runs vertically along the posterior surface of the bodies of the vertebrae inside the vertebral foramen from C2 to the sacrum; reinforces intervertebral discs
Term
LIGAMENTUM FLAVUM
Definition
runs lamina to lamina; limits vertebral flexion
Term
INTERTRANSVERSE
Definition
runs from transverse process to transverse process; limits lateral vertebral flexion
Term
INTERSPINOUS
Definition
runs deep from spinous process to spinous process; limits vertebral flexion
Term
SUPRASPINOUS
Definition
runs superficial from spinous process to spinous process; limits vertebral flexion
Term
LIGAMENTUM NUCHAE
Definition
supraspinous ligament in the cervical spine
Term
TEMPOROMANDIBULAR (TMJ)
Definition
b/w mandible and temporal bone
