4. Sternum - 2What are the three parts of the sternum?1. Manubrium
2. Body
3. Xiphoid process - 3How many vertebrae in the spinal column?12
- 4What is the difference between true, false, and floating ribs? Which ribs are which?True has direct articulation with sternum and coastal cartilage (1-7)
False has indirect articulation (8-10)
Floating has no articulation (11, 12) - 5What are features of a typical rib?Head
Upper articulate facet
Neck
Lower articulate facet
Tubercle
Body
Coastal groove
3 Articulations - 6How many articulations does a typical rib have? Which features articulate with what?3 articulations
Upper articulate facet articulates with vertebrae ABOVE
Lower articulate facet+ Tubercle articulates with CORRESPONDING vertabrae - 7What does the coastal groove contain?The neuromuscular bundle
- 8Why is Rib 1 an atypical rib? (4)Only has one facet instead of two
Articulates with just T1
2 Coastal grooves
Sharply curved - 9Why is rib 2 an atypical rib?Longer/thinner, has tuberosity on surface for muscle
- 10Why are ribs 10, 11, 12 atypical?One facet that articulates with corresponding vertebrae
11 and 12 are short, no neck/tubercle/coastal cartilage - 11What are 3 functions of the thorax?1. Attach muscles
2. Protect internal organs
3. Respiration - 12What direction do external intercoastal muscles run? What is their role in breathing?They run anteriorinferiorally
Contract/move up during inspiration - 13What direction do internal and innermost intercoastal muscles run? What is their role in breathing?Opposite external
Contract/move down - 14Intercoastal muscles are innervated byIntercoastal nerves
- 15The neuromuscular bundle contains1. Intercoastal vein
2. Intercoastal artery
3. Intercoastal nerve - 16The neuromuscular bundle is supplied byThe mixed spinal nerve
- 17What type of joint is the intervertebral joint?Secondary cartilaginous (fibrocartilage composition)
- 18What type of joint is the sternalcoastal joint?The first joint is primary cartilaginous
The rest are synovial - 19What type of joint is the costalvertabral joint?Synovial plane joint
- 20What type of joint is the interchondral joint?Synovial plane joint
It is the connection between coastal cartilages of 6-7, 7-8, 8-9 - 21What type of joint is the coastalchondral joint?Primary cartilaginous
