the range of movement of the entire vertebral column and its
individual regions

Becomes prominent as infant begins to hold head erect, as weight of the head is
redistributed over the cervical vertebrae
▪
Cervical
○
When infant begins to walk, assumes an upright posture so body weight
redistributed over the lumbar vertebrae
▪
Lumbar
○
Do not become obvious until infancy
○

Lateral curvature of the VC, sometimes accompanied by rotation

-
Abnormal curvature posteriorly in thoracic region
○
Produces hunchback

Commonly occurs with osteoporosis

Document Summary
Describe the regions and functions of the vertebral column. Describe the range of movement of the entire vertebral column and its individual regions. Start with 33 and end with 26 after fusion and development. Becomes prominent as infant begins to hold head erect, as weight of the head is redistributed over the cervical vertebrae. When infant begins to walk, assumes an upright posture so body weight redistributed over the lumbar vertebrae. Lateral curvature of the vc, sometimes accompanied by rotation. Commonly occurs with osteoporosis wk 8 page 2. Anterior tilting of the pelvis with increased extension of the lumbar vertebrae. Describe the main anatomical features of the typical and atypical vertebrae. Identify the atlas, axis, other cervical, thoracic, lumbar, sacral and coccygeal vertebrae and recognise their characteristic features. Spinous and transverse processes = muscle and ligament attachment sites. Articular processes = make joints with vertebrae superiorly and inferiorly. Support and movement of the head and neck.
