Thoracic Spine and the Ribs
T2 landmark
sternal notch
Rib dysfunction during exhalation
stuck in exhalation, key rib is the uppermost of the group
>50 degrees of scoliosis results in
surgery
T3 landmark
spine of scapula
Diaphragm innervation is where?
C3-5
Rib 2 muscles
Posterior scalene, serratus ant
Rib 10
Articulates only with T10
Ribs 11 and 12
Articulates only with their corresponding vertebra, lack tubercles
True Ribs
Attach Directly or though condral mass to sternum (Ribs 1-7)
20-40 degrees of scoliosis results in
Bracing
Floating Ribs
Do no connect to sternum at all (Ribs 11 and 12)
False Ribs
Do no directly connect to sternum (Ribs 8-10)
Rib 2
Large tuberosity on shaft for serratus anterior
Ribs 10-12 muscles
Latissimus dorsi
Rib 3-5 muscles
Pectoralis minor
Rib motion of upper ribs 1-5
Pump handle
Typical ribs
Ribs 3-10
Main motion of the thoracic spine
Rotation
Ribs 6-9 muscles
Serratus anterior
Rib dysfunction during inhalation
Stuck in inhalation, key rib is the lowest of the group
T10-12 rules of 3
T10 follows T7-9, T11 follows T4-6 and T12 follows 1-3
T4-6 Rules of 3
TP are 1/2 segment about SP
T7-9 rules of 3
TP are at the level of the SP of the vertebra above
T1-T3 Rules of 3
Transverse processes at the level of corresponding spinous process
What are typical ribs?
Tubercle that articulates with the corresponding transverse process, head that articulates with the vertebra above and the corresponding vertebra
T4 landmark
angle of Louis
Rib 1 muscles
anterior and middle scalenes
Rib 1
articulates only with T1, has no angle
Rib motion of middle ribs 6-10
bucket handle
Rib motion of lower ribs 11-12
caliber
>60 degrees of scoliosis results in
compromised heart and lung function
T7 landmark
inferior angle of scapula
Parts of typical ribs
neck, angle and shaft.
T4 dermatome
nipple
Intercostals help evelate what?
ribs during inhalation
What are the secondary muscles of respiration?
scalenes, pectoralis minor, serratus anterior and posterior, quadratus lumborum and latissimus dorsi
T10 dermatome
umbilicus
Scoliosis
vertebral bodies rotate toward the convexities
Diaphragm attaches to what?
xyphoid, ribs 6-12 and L1-3
