| is at level of T3-T4, attaches first rib, contains jugular notch, clavicular notch, sternal angle |
|
|
Term
|
Definition
–Level of T10 vertebral body
–7th rib attachment
–Anatomic landmark:
•Subcostal angle
•Superior liver border
•Inferior heart border
•Central tendon of diaphragm |
|
|
Term
| rotation of cartilagenous joint of ribs? |
|
Definition
| there is no rotation at these junctions. any movement is provided back at the vetertebral junction (a synovial joint) |
|
|
Term
| principal muscles of inspiration |
|
Definition
–External intercostals
•Infero-lateral orientation
•Innervation: intercostal n.
•Action: elevate rib
–Internal intercostals (interchondral part)
•Infero-medial orientation
•Innervation: intercostal n.
•Action: elevate ribs
–Levatorcostarum
•Infero-lateral orientation
•Innervation: posterior primary rami C8-T11 n.
•Action: elevate ribs
diaphragm gets pulled down
-innervation from C3-5 (phrenic nerve) is important |
|
|
Term
| principal muscles of exspiration |
|
Definition
•Primary Muscles of Expiration
–Elastic recoil
–Internal intercostals (interosseous part)
•Infero-medial orientation
•Innervation: intercostal n.
•Action: depress ribs
–Sternocostalis
•Infero-medial orientation
•Innervation: intercostal n.
•Action: depress ribs |
|
|
Term
| antagonistic relationship of muscles during respiration |
|
Definition
tonus is highest in the diaphragm in inspiration when it is lowest in the abdominal muscles
abdominal tonus is highest and diaphragm tonus is lowest during expiration |
|
|
Term
| what determines rib motion? |
|
Definition
the orientation of the costovertebral and costotransverse joints
the upper ribs have a greater angle of axis with respect to the sagital plane than the lower ribs |
|
|
Term
|
Definition
characteristic of ribs 11 and 12, it changes both the AP and transverse diameter of the ribs
ribs 11 and 12 move posteriorly and inferiorly during inspiration
anteriorly and superiorly during exhalation
slightly counter intuitive for 11 and 12 |
|
|
Term
| key rib in an exhalation dysfunction? inhalation dysfunction? |
|
Definition
rib stays down, bottom is key rib
rib stays up, top is key rib |
|
|
Term
| 11th and 12 rib inhalation dysfunction? exhalation dysfunction? |
|
Definition
–Inhalation dysfunction
•Ribs do not fully move anteriorly and superiorly
–Exhalation dysfunction
•Ribs do not fully move posteriorly and inferiorly |
|
|
Term
| describe the pelvis during delivery. |
|
Definition
| the baby is initially found in the false pelvis. The ilium needs to diverge to allow for passage of the baby. The the ischia will diverge and the ilum with converge |
|
|
Term
|
Definition
| first perform a standing flexion test. any dysfunction thereafter will be named for the side found to be abnormal during the standing flexion test |
|
|
Term
| does an ASIS compression test test for sacro-ilial or ilio-sacral? |
|
Definition
|
|
Term
| what are innominate flares? |
|
Definition
| where the ASIS on one side is subluxed closer to (inflare) or away from (outflare) the medline |
|
|
Term
| characteristics of an innominate that cause a patient to have apparent leg lengthening on one side |
|
Definition
| inferior shear or anterior rotation |
|
|
Term
characteristics of an innominate that cause a patient to have apparent leg shortening on one side
|
|
Definition
| superior shear and posterior rotation |
|
|
Term
| How many costovertebral ligaments are there, and what are they called? |
|
Definition
¨Costovertebral Ligaments (2)
¤Interosseous ligaments- between the two demifacets to the I.V. disc
¤Radiate ligaments with three bands:
nSuperior-head of rib to vertebra above
nIntermediate-head of rib to I.V. disc
nInferior-head of rib to corresponding vertebra |
