NOTES Ch 7 2/13
Sternum, ribs, vertebrae
HYOID BONE
• U –shaped bone• Under mandible and above larynx• Only bone not forming a joint
(touching another bone)
STERNUM
• Breastbone• Where ribs connect• 3 parts - manubrium - body - xiphoid process
Pectus excavatum
RIBS (12 pair / 24)1. TRUE RIBS (7 pr) * attach directly to the sternum by
costal cartilage (flexible for breathing)
2. FALSE RIBS (5 pr) * do not attach to sternum directly
Floating – last 2 pairDo not attach to sternum at all
SPINAL COLUMN
•26 bones
•Spinal cord runs through VERTEBRAE (protect it)
•Curved – increases carrying capacity, balance
• INTERVERTEBRAL DISKS – cartilage between vertebrae to cushion
1. CERVICAL VERTEBRAE (7) 1st – atlas 2nd axis
2. THORACIC VERTEBRAE (12) 12 prs of ribs attach to them
3. LUMBAR VERTEBRAE (5)
4. SACRUM (1) 5 separate till 25
5. COCCYX (1) “tailbone” 4-5 separate in child
CHALLENGE
Can you learn and name all 26 vertebrae bones in 3 minutes ????

SPINAL COLUMN PROBLEMS
1. SCOLIOSIS – abnormal lateral curve (side to side)
2. KYPHOSIS – thoracic curve extended
“humpback”
3. LORDOSIS – extended lumbar curve
