Combination of any one of the major 3 classes of joints
Radioulnar joint (fibrous and pivot joints)
19
Q

C1/C2 joint

A

Compound synovial

Trochoid and planar synovial

20
Q

Intervertebral joints

A

C3-S1

Symphysis

21

23
Q

Joint of Luschka

A

Joint between the uncinate process of the inferior vertebra and beveled inferior surface of the superior vertebra in cervical vertebra

24
Q

Anterior Longitudinal L.

A

Lines the anterior surface of the vertebral bodies

25
Q

Posterior Longitudinal L.

A

Lines the posterior/dorsal portion of the vertebral bodies

26
Q

Ligamentum Flavum

A

Pale yellow fibers that travel on the ventral surfaces of ventral laminae

27
Q

Interspinous L.

A

Travel between adjacent spinous processes of vertebrae

28
Q

Intratransverse L.

A

Travels between transverse processes of adjacent vertebrae

29
Q

Supraspinous L.

A

Travels on the posterior/dorsal surface of the spinous processes
Continued as ligamentum nuchae in the cervical region

30
Q

Intervertebral discs

A

Annulus fibrosis: tough fibrous outer part of discs

Nucleus pulposus: soft, gelatinous inner part of discs

31
Q

Herniation of discs

A

Usually occurs posterolaterally because of the anterior and posterior longitudinal L. Placement
L4/L5 or L5/S1
Resultant bulge compress spinal nerves

32
Q

Second number rule

A

If an injury occurs to the cervical and lumbar regions of the spinal cord, the vertebral level at which the prolapse occurred will affect the spinal nerve of the second affected vertebra
Injury at C4/C5, C5 spinal nerve is affected
L4/L5, L5 spinal nerve is affected

35
Q

Cruciate L.

A

Superior longitudinal band: from transverse L. To occipital B.
Transverse L: from tubercle of transverse L. around the odontoid process and to the contralateral tubercle of transverse L.
Inferior Longitudinal L.: From transverse L. To Axis

36
Q

Alar L.

A

From odontoid process of axis to the lateral margins of the foramen magnum

37
Q
