Back & Vertebra Flashcards
Ligamentum flavum
Connects the lamina
Anterior longitudinal ligament
Connects the exterior of vertebral bodies
Posterior longitudinal ligament
Connects the interior of vertebral bodies
Supraspinous ligament
Connect the exterior spinous process
Interspinous ligament
Connects in between spinous processes
What plane is movement permitted in for cervical vertebra?
Transverse
What plane is movement permitted in for thoracic vertebra?
Frontal (coronal)
What plane is movement permitted in for Lumbar vertebra?
Sagittal
What movements occur in cervical vertebra?
Flexion, extension, rotation, lateral flexion
What movements occur in thoracic vertebra?
lateral flexion and rotation
What movements occur in lumbar vertebra?
Flexion and extension
What movement are the posterior vertebral muscles responsible for?
Extension of spine
What movement are the anterior vertebral muscles and side muscles responsible for?
Flexion of spine
What is bilateral flexion and example?
Two muscles contracting simultaneously for singular movement - anterior muscle and side muscle for flexion of spine
What is unilateral flexion and example?
One muscle contracting for movement - side muscles contracting for rotation and lateral flexion
Where do the erector spine muscles lie?
Posteriorly to vertebral transverse and spinous processes
Main anterior muscle in neck?
Sternocleidomastoid
Main anterior muscles of abdominal wall?
Transverse/rectus abdominus and internal/external obliques
What happens when flexor and extensors muscles of the trunk contract simultaneously and what bodily functions are facilitated by this?
Increase intra-abdominal pressure
- Coughing
- Vomiting
- Excretions (faeces)
- Child birth
What is the vertebral level of the vertebra prominens?
C7
