Document Summary
2 palatine + 2 maxillae = hard palate : 2 inferior nasal chonchae, 1 vomer, 1 mandible, auditory ossicles incus, malleus, stapes, hyoid bone. Attaches muscles of tongue and nexk, assists in swallowing : vertebral column. Separated into 5 regions: : cervical (7, thoracic (12, lumbar (5, sacrum (1, coccyx (1) typical vertebral structure: . O spinous process (1) median posterior projection. O transverse process (2) lateral bony projections for muscle attachment. O pedicle (2) connects body to transverse process. O vertebral foramen hole for spinal cord. O superior + inferior articular facets articulate with vertebrae above and lamina (2) connects the two processes below intervertebral foramina exit for spinal nerves. Characteristics of vertebrae by region: : cervical (c1-c7) C1-c7 : all have transverse foramen lomoar cpsd| 987298. All articulate with ribs via costal facets : lumbar (l1-l5) All have large bodies & rectangular spinous processes : sacrum. Articulates with ilium (appendicular skeleton) and 5th lumbar vertebra (l5) : coccyx.
