what is found in ribs and what is its purpose
hematopoietic tissue that can make red blood cells
which are your true ribs
1-7
which are your false ribs
8-10 (do not attach directly to sternum)
which are your floating ribs
11+12 (no cartilage)
what is the purpose of intercostal spaces and costal cartilage
to allow your ribcage flexibility when your breath
how do you name a rib space
the space is named for the rib it is below
ex. rib space 2 is below rib 2
which are your typical ribs
3-9
what is a demifacet and where are they found
shallow depressions on the vertebrae that articulate with the facets of the ribs
what is the purpose of the tubercle of a rib
has a facet that articulates with the transverse facet of the vertebrae
1.)
neck

which are your atypical ribs
1st, 2nd, and 10th-12th
what are the atypical features of your 1st rib
broad, short, sharply curved, and single facet
what are the atypical features of your 2nd rib
thinner, less curved, longer than first rib, two facets, and a rough area
what is the atypical feature of ribs 10-12
one facet (only articulates with one vertebra)
what are the atypical features of ribs 11 and 12
short with no neck or tubercle
1.)
1st rib
2.)
2nd rib
3.)
11th rib
4.)
12th rib
what is gorilla rib
extra pair of floating ribs
what is thoracic outlet syndrome
when blood vessels and nerves are compressed between the clavicle and first rib
can be caused by trauma, pregnancy, or extra ribs
presents with pain, weakness, and coldness in fingers
explain separation of rib
separation costochondral junction (area where rib meets cartilage)
typically occurs between ribs 3-10
ribs move upward
explain dislocation of rib
dislocation of a costal cartilage from interchondral joints (where cartilage meets sternum)
typically occurs between ribs 8-10
occurs in body contact sports
which rib cartilages attach to the manubrium
1st rib and half of 2nd ribs cartilage
what rib cartilage attaches to the sternal angle
cartilage of 2nd rib
what rib cartilage attaches to the body of the sternum
cartilage of ribs 3-7
what attaches to the xiphoid process
abdominal muscles
1.)
suprasternal notch
2.)
manubrium
3.)
sternal angle (angle of Louis)
4.)
body of sternum
5.)
xiphoid process
6.)
clavicular notch
what is pectus excavatum
breastbone is sunken into chest due to halves of sternum not fusing properly
can be corrected if done early enough
what is pectus carinatum
breastbone projects because halves of sternum don’t fuse properly
can be correct if done early enough
what nerve innervates the diaphragm
phrenic nerve
what do you use for inspiration
diaphragm (phrenic nerve), external intercostals, and right and left crura
what muscles do we used for forceful expiration
internal intercostals
rectus abdominis
external obliques
internal obliques
1.)
right and left crura
3.)
external intercostals (more lateral; fibers run towards sternum)
2.)
internal intercostals (more medial; fibers run from sternum)
1.)
internal obliques
2.)
external obliques
3.)
rectus abdominis
