Q

Thoracic Skeleton

A

1- True ribs (7 pair)

2- False ribs VII to XII

articulate ant with costal cc of the ribs abv

dont artcl8 at all

3- Floating ribs XI and XII

2
Q

Typical Rib

A
  1. head
  2. neck
  3. tubercle
  4. angle
  5. costal groove
  6. costal cartilage

Rib fx can tear parietal pleura- cz air to enter the pleural cavity and cz pneumothorax (elastic recoil and lung collapse)

3
Q

Rib I superior surface

A
  1. neck
  2. tubercle
  3. area of attachment of serratus anterior
  4. costal cartilage
  5. groove for subclavian vein
  6. scalene tuercle (att. ant. scalene)
  7. groove for subclavian a.
  8. area for att. of mid. scalene
  9. head with articular facet
4
Q

Sternum

A
  1. Jugalar notch
  2. manubrium of sternum
  3. sternal angle (manubriosternal jt)
    • easily palpated- bc manubrium angles pst. on the body of sternm forming a raised feature.
  4. transverse ridges
  5. body of sternum
  6. xiphoid prc.
  7. art. fct for rib VII
  8. art. fct ribs III-VI
  9. art. fct rib II
  10. art fct. rib I
  11. art. site for clavicle
5
Q

Vertebra, ribs and sternum

A
  1. superior costal facet
  2. body of sternum
  3. costal cartilage
  4. rib V
  5. costal fct on trv prc
  6. sup art prc
  7. intervrtbl body
  8. vrtbrl body
  9. inf costal fct
  10. inf art prc

Because of this unique articulations between the ribs, vertebrae, and sternum, elevation and depression of the ribs changes the anteriposterior and lateral dimensions of thorax.

6
Q

When the ribs are elevated, they move the sternum …

A

upward and forward

7
Q

When the ribs are depressed, they move the sternum …

A

downward and backward

8
Q

Pump-handle type of movement

A

When the ribs are elevated, they move the sternum upward and foreward.

When the ribs are depressed, they move the sternum downward and backward.

Because the anterior ends of the ribs are inferior to the posterior end.

9
Q

Bucket-handle movement changes the

A

lateral dimensions of thorax.

Bc the midshaft of each rib tends to be lower than the two ends, when the shafts are elevated the middle portion moves laterally.

10
Q

Thoracic Wall

A
  1. Intcstl n
  2. intcstl a
  3. intcstl v
  4. collateral branches
  5. parietal pleura
  6. endothoracic fascia
  7. costal grv
  8. innermost intcstl muscle
  9. internal intcstl m
  10. external intcstl m
11
Q

Thoracic cavity

A
  1. ext intcstl m
  2. int intcstl m
  3. innermost intcstl m
  4. pst intcstl a
  5. ant intcstl a
  6. int thoracic a
  7. ant ramus of sp. n (intercostal n)
  8. R lung
  9. L lung
  10. mediastinum
12
Q

Intercostal space

nerves and vessels

A
  1. pst. intcstl a and v
  2. ant intcstl a and v
  3. internal thoracic a and v
  4. ant perforating branches of intercostal vessels
  5. ant cutaneous branch of intcstl nn
  6. lat branches of intcstl nn and vv
  7. collateral branches of intcstl nn and vv
13
Q

To remove the air from the pleural cavity a tube must be inserted —— aspect of the rib.

A

The tube is inserted over the superior aspect of the rib because insertion at the inferior border of the rib could injure the intercostal vein, artery and nerve lying in the costal groove.
