Spine, head and neck Flashcards
What are the joints that hold the skull together
Immovable joints called sutures
What is the function of the crainial bones?
Protect the brain the brain, blood vessels and nerves
What is the function of the facial bones?
Framework for the face protect and provide support for the nerves and blood vessels.
What are C1 and C2 called
Atlas and axis
What are the joints form C2 to the sacrum?
Cartilaginous joints
What is the function of Cartilaginous joints?
Withstand and distribute loads and resist movement
What movement occur in the cervical region of the spine?
Flexion extension lateral flexion
What movement occur in the thoracic region of the spine?
rotation only
What movement occur in the lumbar region of the spine?
Flexion/extension lateral flexion
What movement occur in the sacral region of the spine?
No movement
Name the erector spinae muscles
Spinalis longissimus iliocostalis
What is the function of the erector spinae muscle group?
– Extensor – Lateral flexion – Rotation
What are segmental muscles?
- Short running muscles formed along entire vertebral column
Where do the spinal column anterior and posterior longitudinal ligaments travel to and what is their function?
- Sacrum body to atlas body - Limits hyperextension and extension
Where do the spinal column interspinous and supraspinous ligaments travel between and what is their function?
- Runs between spinous processes - Limits trunk flexion
What are the sections of the ribs?
1-7 true ribs 8-10 false ribs 11-12 floating ribs
What movements can the trunk do?
Flexion extension lateral flexion rotation
Transverse abdominis function
Compression and supports abdominal organs
Rectus abdominis function
Flexion Compression Lateral flexion (on same side)
Internal obliques function
Together = flexion Singular = rotation and lateral flexion on contraction side
External obliques function
Together = Flexes spine Singularly = rotation (on opposite side) and lateral flexion (on same side)
