DPT 6160 EXAM 2 STUDY GUIDE EXAM QUESTIONS AND
ANSWERS WITH COMPLETE SOLUTIONS VERIFIED
What are the apertures of the thorax?
Superior and inferior thoracic aperture
What are the three parts of the sternum?
1. manubrium
2. body
3. xiphoid process
What type of joint is the intervertebral disc?
Symphysis
Lordosis
abnormal anterior curvature of the lumbar spine (sway-back condition)
Kyphosis
excessive outward curvature of the spine, causing hunching of the back.
What is the primary function of the IV disc?
Shock absorption
Anterior Longitudinal Ligament
connects anterior surfaces of adjacent vertebral bodies
primary resister of extension
Posterior Longitudinal Ligament
, Connects all the posterior surfaces of the vertebral bodies
weak resistor of flexion
What are the articulating surfaces of the zygapophyseal joints?
Superior and Inferior Articular Process
What type of joint is the zygapophyseal joint?
Synovial, plane
Cervical vertebrae articular facets
transverse angle 45 degrees, permits flexion/extension, lateral flexion, and rotation
Lumbar vertebrae articular facets
sagittal plane, blocks/minimizes rotation, permits flexion/extension
Thoracic vertebrae articular facets
coronal plane, permits rotation, some flexion/extension (blocked by spinous process
overlap)
Zygapophyseal Joint Capsule
thin, loose
Blood supply of the zygapophyseal joint
supplied by periosteum, equatorial branches of cervical and segmental arteries
Nerve supply of the zygapophyseal joint
Articular branch from medial branch of posterior rami of spinal nerves, supplied by 2
adjacent spinal nerves, also supplied by meningeal branches of spinal nerves
Spinal stenosis
narrowing of the spinal curve, and compression of spinal nerves
What are the ligaments of the costovertebral joints?
