Spine Flashcards
How many vertebrae do we have in the spine?
33 all together
7 cervical vertebrae
12 thoracic vertebrae
5 lumbar vertebrae
Sacrum & Coccyx (fused vertebrae)
Lordosis
Inward curve
Kyphosis
Rounded back
Parts of a vertebrae
Facet joints
The joint that allows the vertebrae to sit on top of each other
Allow rotation & side movements
Facet joint pain
When doing side or later flexion as it closes the joints causing discomfort
Cervical spine
1) C1 Atlas
2) C2 Axis
3) C3 - 6
4) C7 Vertebra Prominens
Sally has a pain on the right side of her neck, if she tilts her head towards the right side she feels pain? What is causing this and why?
Most likely joint pain rather than muscle as she is closing the joints
Sally has a pain on the right side of her neck, if she tilts her head towards the right side she doesn’t feel pain but when tilting to the left she does? What is causing this and why?
Most likely muscle pain and she is stretching her muscles
Disc involvement in movement
When bending forward in something like the roll down it can cause a weakening at the back of the disc which can cause X?
Disc herniation (slip disc)
What movement should be done for people with disc herniation?
Extension movements like swan dive level 2 & cobra
What do discs allow?
1) Movement
2) Shock absorption
Muscles of the cervical region (neck)
Origin and instertion of the Sternocleidomastoid muscle
Origin: Clavicle & Sternum
Insertion: mastoid process (temporal bone behind ear)
Movement of the sternocleidomastoid
Rotation and flexion
Sternocleidomastoid
How many pairs of scalene muscles are there?
3
Where can scalene muscles be found?
Lateral neck
Name the 3 scalene muscles
1) Anterior scalene
2) Middle scalene
3) Posterior scalene
Anterior scalene origin
Origin: anterior tubercles of the transverse process of the 3rd - 6th vertebrae (c3 - c6)
Anterior scalene insertion
Insertion: inserts as a flat tendon into the scalene tubercle on the inner border of the 1st rib, the ridge on the upper surface of the 2nd rib
Action of the anterior scalene
Elevates 1st rib and laterally flexes Cx to same side
