Anatomy Flashcards
The student is able to describe the concepts “tangential surface”, “normal”, “capsular pattern”, “closed pack position” and “maximal loose pack position”.
Tangential surface → the straight line you could draw from one edge of the concave part to the other.
Normal → perpendicular to the tangential surface
Capsular pattern → Order of movement limitations in a joint typical to inflammation of the entire joint capsule .
Closed pack position → Maximal fitting ball and socket;
Capsular ligament system maximally contracted; stability
Maximal loose pack position → All other positions: loose-packed positions; MLPP / resting position: great mobility; important position for examinations and treating the joint (non-specific traction and translation techniques)
The student is able to describe the arthrokinematic movements based on the convex/concave rule, for every joint to which this rule applies.
When changing the angle of the convex (=roll), translation takes place in the opposite direction (=slide)
When changing the angle of the concave (=swing), translation takes place in the same direction (=glide)
convex → complex → opposite
concaaf → braaf → same direction

The student is able to name the functional anatomy of the high-cervical area.
The high-cervical area consist of C0 - C2. Between C1 and C2 is no disc. C0 = os occipital
→ C1 = Atlas
• The lack of a vertebral body
• Upper articular surfaces are concave
• Lower articular surfaces of C1 are convex
• Rudimentary spinous process
• Relatively large transversii process with a foramen
• C0 on C1 is a roll-slide movement through convex on concave. At C1 and C2, this is convex on convex, so there is no real roll-slide movement.
→ C2 = Axis
• The dens the tooth of the turner
• Anterior and posterior articular fascia
• Superior and inferior articular fovea
• Powerful spinous process
• Weak transverse process
• If the dens is not held in place by the transversum atlantis ligament, the dens can damage the spinal cord that lies behind it. Then there is high cervical instability. For this, high cervical stability tests are performed.
→ High cervical ligaments
- ligg. alaria (left/right): From the dens to the side of the foramen Magnum skull. Inhibits movability of the dens.
- lig. cruciforme atlantis: crosses behind dens. transversum atlantis and faciculi longitudinale. Inhibits movement dens. Right lig inhibits lateroflexion left.
- lig. apicis dentis. From top dens to sides of foramen magnum skull. Inhibits movement dens.
→ C2 = Axis
• The dens the tooth of the turner
• Anterior and posterior articular fascia
• Superior and inferior articular fovea
• Powerful spinous process
• Weak transverse process
• If the dens is not held in place by the transversum atlantis ligament, the dens can damage the spinal cord that lies behind it. Then there is high cervical instability. For this, high cervical stability tests are performed.
→ Mobility C0-C2
• Flexion Extension 45 degrees
• Rotation 83 degrees (le and right)
• Lateroflexion 8 degrees (le and right)
Flexion extension 45 degrees of which:
29 degrees between C0-C1
16 degrees between C1-C2
Rotation li-re → 83 degrees rotation of which:
2 degrees between C0-C1
81 degrees between C1-C2
Lateroflexion left/right →8 degrees 9 small
C0-C1 and C1-C2 together to left and right 8 degrees
The student is able to describe the structure of the vertebral joints
Facetjoints
- art. symphysis intervertebralis = the anterior intervertebral joint; This joint consists of 2 corpora + the intermediate discus
- art. zygapophysialis = posterior intervertebral joint
This joint consists of the superior articular process and the inferior articular process
The student is able to describe the structure of the costovertebral joints
The ribs are attached to the spine by art. costovertebralis:
- art. capitis costae joint consists of:
• caputcostae
• corpus vertebrae
• intervertebral disc - art. costotransversal joint consists of:
• tubercle costae
• transversus process
The student is able to list the movement possibilities of the vertebral joints.
• Cervical vertebrae:
- Facet joint in transversal plane
- longitudinal axis
- movement rotation
• Thoracic vertebrae:
- Facet joint in fontal plane
- sagital axis
- movement lateral flexion
• Lumbar vertebrae:
- Facet joint in sagital plane
- transversal axis
- movement flexion and extension
The intervertebral foramen becomes smaller with extension and with flexion the intervertebral foramen widens
The student is able to list the movement possibilities of the costovertebral joints.
The ribs move mainly during breathing:
Insulation: ribs move to: ventrally, laterally and cranially
Exhalation: ribs move towards: medial, dorsal and caudal
The following ribs are synchronic (less movement possible):
Rib 1: because it is attached directly to the manubrium sterni via the cartilage without there being a synovial joint in between (the art. sternocostalis).
Ribs 6 and 7: there is also no synovial joint in between, these ribs attach directly to the sternum
The student is able to list the movement possibilities of the SI joint.
- Nutation: the promoter moves forward, pelvic entrance becomes smaller, pelvic exit increases. (flexion of the sacrum)
- Contranutation: the promoter moves posteriorly, os coxygis moves forward, iliac crest moves laterally. Pelvic entrance gets bigger, pelvic exit gets smaller. (extension of sacrum)
The student is able to describe the structure of the disc of the front intervertebral joint.
art. symphysis intervertebralis = the anterior intervertebral joint
This joint consists of 2 corpora + the intermediate disc
Discus consists of:
• Outer layer: anulus fibrosis (sitting a lot
collagen fibers) good resistance pulling
• Inner layer; nucleus pulposus
(jelly-like core), there is also a bit of movement in this. (impact resistant).
When you flex the spine, the nucleus pulposus moves backward. A hernia usually occurs at the back of the spine because that is where the spine is most stressed.
