famous facets
This facet joint favors FLX and EXT more than sidebend and hinders rotation
Upper L/S (L1/L2)
The upper traps, erector spinae, scalenes, and SCM mm are all examples of ________ stabilizers.
Secondary
pedicles
This ligament fills the space between the successive spinous processes
Interspinous Ligament
Palpate the bifid structure of C4.
SP of C4
This facet joint allows for FLX & EXT & SB but hinders ROT
C0/C1 Facets
Name the spinal cord segments of the LOWER cervical region.
C3-C7
Covers posterior aspect and primary job is spinal cord protection
laminae
Helps prevent anterior IVD herniation
Anterior Longitudinal Ligament
Palpate the right mm that does expiration and ipsilaterally flexes the trunk.
R QL mm
This facet joint favors ROT more than FLX & EXT and hinders SB
C1/C2 Facet joint
Name the levels of thoracic vertebrae that have costal demi-facets.
T2-T9
Attachment site for muscles and articulates with the ribs in the thoracic region.
Transverse processes
Protects the posterior side of the spinal cord and fills in the gaps between successive laminae
Ligamentum Flavum
Palpate the common attachment site of the left levator scapulae mm and left oblique capitis superior mm.
left TP of C1
Between Frontal and transverse planes. Favor SB > ROT while hindering FLX - EXT
T2-T9 Thoracic Facets
(R)ROT with (R)SB creates this type of motion.
Type II motion
A ring-like structure that is different from typical vertebrae. Has anterior and posterior arches instead of pedicles and laminae
Atlas (C1)
Runs from the rib's posterior neck to the TPs articular facet on the same-level vertebra
Costotransverse Ligament
Palpate the left structure that articulates with the full costal facet of T1.
left 1st rib
Favors SB > FLX & EXT and hinders rotation
Lower L/S (L4/L5)
Name the most important factor when considering the torque capacity of a mm.
PCSA
The vertebral bodies are thick and sturdy. The SPs are broad and project directly posterior. Most of the TPs are thin and project directly lateral
Lumbar Vertebrae
Includes three parts that are all tensioned by anterior head glide on the neck
Cruciate Ligament of Atlas
(Transverse ligament, S. longitudinal band, I. longitudinal band)
Palpate the insertion of the muscle that is associated with low back pain
