Functions of the thoracic cage
resiration, protection, pump for venous and lymphatic return and support structure for upper extremities
T1-T3 lcation of spinous process
at level of transverse process of its own
T4-T6 location of spinous process
halfway between 2 transverse processes
T7-T9 location of spinous process
level of transverse process of vertebrae below it
T10-T12
about the same level as it sown transverse process but not exactly equal
definition of true ribs
attach directly to the sternum via chostochondral cartilage
what ribs are true ribs
ribs 1-7
definition of false ribs
attach to sternum via synchondrose to the costochondral cartilage of rib 7
which ribs are false ribs
8-12
which ribs are floating ribs
11-12
definition of floating ribs
do NOT attach to the sternum AT ALL
which ribs are typical ribs
ribs 3-9 and sometimes 10
which ribs are atypical ribs
1,2, 11,12 and sometimes 10
What landmarks will typical ribs have
tubercle, head, neck, angle, and shaft
head of rib
articulates with corresponding and immediately superior vertebrae via demifacets
what part of the rib contains the costal groove
shaft
ribs _______ rotate at the ____________ joint
ribs 1-7 rotate at costotransverse joint
ribs __________glide at the ________joint
8-10, costotransverse joint
do ribs 11 and 12 articulate with the transverse process
NO!
rib 1 is what type of joint
synchodrosis (non-synovial)
ribs 2-7 are what type of joints
synovial articulations; plane gliding
why is rib 2 atypical
because of its large tuberosity for serratus anterior
why are ribs 11 and 12 atypical
articulate only with corresponding vertebrae and LACK tubercles
why is rib 1 atypical
has not rib angle
