Lumbar vertebrae and Sacrum in depth Lumbar Features - Found in the lower back region - Largest moveable part of the vertebral column - Weight bearing - Articular surfaces are orientated: superior face in towards the middle, inferior face away = articulate anteriorly and posteriorly with the one above and below it Number - 5 Distinguishing features (MOOSE - Heavy and large - Short, blunt processes - Body is oval in shape ) Sacral and coccygeal vertebrae Features - Found in the lower back region - For weight bearing and articulation of the lower limbs (stable point of attachment for the appendicular skeleton) - Immovable because the bones are fused together - At the very top = the promontory/shelf that holds the weight of the other vertebrae Number - Sacral vertebrae = 5 bones fused together - Coccygeal vertebrae = 4 bones fused together Distinguishing features - Fused bones - Foramina - Sacral canal (posterior) for the passage of the spinal cord to supply the lower limb structures - Coccyx is the point of attachment for the pelvic floor muscles Region Cervical vertebrae Features of this region - Thoracic vertebrae - - Number Distinguishing features Found in the neck region Movement of the head and neck - 7 C3-C6 = typical C1, C2, C7 = atypical - Attachment points for the ribs to create the thoracic cavity Allow movement of the vertebral column and thoracic cage (respiration) - 12 T2-T9 = typical T1, T10, T11, T12 = atypical - - Lumbar vertebrae - Sacral and coccygeal vertebrae - Found in the lower back region Largest moveable part of the vertebral column Weight bearing Immovable Attachment for the lower limb girdle (attaches appendicular to axial) - 5 - - Sacral = 5 Coccygeal = 4 - Transverse foramen Smallest and lightest Body is bean shaped Spinous process is short and projects horizontally GIRAFFE Costal facets (fingerprint) Long inferiorly sloped transverse process Evidence of articulation (marking to identify it) Pedicle is very obvious Body is heart shaped MOOSE Heavy and large Short, blunt processes Body is oval in shape All fused together Foramen
