Week 8 Flashcards
What body systems are important for the trunk
Skin and subcutaneous tissues
Muscles
Skeletal System
Nervous
Cardiovascular
Identify vertebral column with curvaturs
- Cervical - concave posteriorly (secondary) - C1-C7
- Thoracic - Convex posteriorly (primary) - T1-T12
- Lumbar - Concave posteriorly (secondary) - L1-L5
- Sacral - convex posteriorly (primary) S1-S5 - fused
- Coccyx
What are the 5 joints of vertebral column
- Joint of bodies - intervertebral, cartligenous, weight bearing
- Joint of arches - facet joints, synovial, articulation between superior and inferior articular process
- Craniovertebral joints - C1 and C2 joints, synovial
- Costovertebral joints - vertebral column and ribs, costal facet, synovial, gliding
- Sacroilliac - weight bearing
What are some cervical vertebral characteristics
Bifid spinous process
Transverse foramen
Smallest body
What are some key thoracic vertebral features
articulation with ribs, heart shaped vertebral body, circular foramen,
What are some key lumbar vertebrae characteristics
Biggest body
Strong spinous process - muscle attach
Distinguish key spinal movements
- Flexion - sagittal plane - anterior movement
- Joint - intervertebral joint
- (muscle must lie anterior to joint)
- Rectus abdominus
- Extension - sagittal plane - posterior movement
- Joint - intervertebral joints
- (must lie posterior)
- Erector spinae muscles
Rotation - transverse plane - (twist movement)
* Direction of muscle fibres
* (oblique)
* Hence internal and external obliques
- Lateral flexion - frontal plane - bending left or right)
- Intervertebral joint
- (needs to be lateral)
- Primary - erector spinae and internal and external obliques
What is the main artery supplying the thoracic and abdominopelvic region
thoracic - descending thoracic aorta
abdom - abdominal aorta
What is the main vein supplying the thoracic and abdominopelvic region
abdomino - inferior vena cava
Thoracic - superior vena cava
