manubriosternal joint
|
aka angle of Louis
junction of upper and middle parts of sternum where the 2nd costal cartilage articulates with sternum level of: lower border 4th T vertebra; bifurcation of thorax **can be felt on surface easily, makes it easy to identify the 2nd rib laterally on each side |
|
|
xiphisternal joint
|
where the 7th costal cartilage joins the sternum at the xiphoid process
|
|
|
manubrium
|
upper part of sternum (one of 3 parts of sternum, incl body and xiphoid process)
|
|
|
intercostal neurovascular bundle
|
runs along costal space
between innermost intercostal muscle and interior intercostal muscle order V A N |
|
|
types of pneumothorax
|
1. Lung puncture by rib fragment
2. Tear of adhesions (spontaneous) 3. Penetrating wound (chest wall and/or lung) |
|
|
costo-diaphragmatic recess
|
pleural cavity below each lung, into which the latter can expand during inspiration
(approx below 6 - 10 rib medial to lateral of lung) |
|
|
bronchopulmonary segments
|
anatomical, functional and surgical macroscopic units of each lung,
receive a third order/tertiary bronchus accompanied by a segmental/tertiary branch of pulmonary artery 10 per lung (R has middle, L has lingual, both sup and inf) (L may be 8-10); seperated by connective tissue |
|
|
Lung lobule
|
basic unit of lung
supplied by bronchiole, lymphatics, and pulm artery branches (pulm vein run bw lobules) approx 30-60 per bronchopulmonary segment 1-2cm across, pyramidal in shape |
|
|
Pulmonary ligament
|
space at root of lung required for normal expansion during inspiration and space for veins of root to prevent over constriction.
|
|
|
mediastinum
|
region in centre of chest; contains:
- heart - major blood vessels - esophagus - trachea |
|
|
thorax
|
ribs
vertebrae sternum |
|
|
accessory muscles of resp
|
insp:
-sternocleidomastoid -scalene -pectoralis minor -serratus exp: -abdominal -intercostals |
|
|
dextrocardia
|
position of heart reversed so apex is misplaced to the right instead of left, usually great vessels and arotic arch mirror image too
- isolated dextrocardia: only heart switched, usually complicated by sever cardiac anomilies = TGA - situs inversus - general transposition of thoracic and abdominal viscera, less complications |
|
|
Situs inversus
|
- general transposition of thoracic and abdominal viscera, less complications
|
|
|
pericardiocentesis
|
drainage of fluid from pericardial cavity
necessary to relieve cardiac tamponade remove excess fluid w wide-bore needle - thru L 5th or 6th intercostal space near sternum, - or infrasternal angle |
|
|
septomarginal trabecula
|
aka moderator band
carries R branch of AV bundle across RV from inferior part of IVS to base of anterior papillary muscle |
|
|
supraventricular crest
|
deflects incoming flow into main cavity RV, and outgoing flow into conus arteriosus toward the pulmonary orifice
|
