Anatomy Flashcards
(17 cards)
Thoracic Wall Components (6)
Ribs Vertebrae Sternum Intercostal Muscles VANL Parietal Pleura
VANL run at
inferior border of each rib
Thoracic Cavity Components
Mediastinum Pleural Cavities (2)
Joints of the Thoracic Wall:
Costovertebral
Costotransverse
Sternocostal
Costovertebral
ribs to vertebrae
Costotransverse
ribs to TRANSVERSE processes of vertebrae
Sternocostal
ribs to sternum via costal cartilage
Pleural cavity component
Lungs
Bronchi
Pulmonary vasculature
Bronchial vasculature
** lungs have 2 blood supplies
Inspiration= _____ volume
increased volume in all directions
Vertical: via diaphragm
AP/Transverse: intercostal
Accessory muslces of Respiration
function when needed (forced inspiration)
Pectoralis Major/Minor, Scalenes, Sternocleidomastoid
fascia of thorax (3)
Pectoral
Clavipectoral
Endothoracic
Nerves of Thorax
Intercostal
Subcostal
Vasculature of Thoracic Wall
located in costal groove
anteriorly: drains Internal thoracic veins
Posteriorly: drains azygos system
pleural fluid
produced and reabsorbed by the 2 layers of pleural cavity
creates negative pressure
function of negative pressure
helps lung tissue adhere to thoracic cage
allows them to expand together
lungs lobes
L: has 2 (bc heart)
R: 3
hilum of lungs
site of entrance/exit for mainstem bronchus and pulmonary vasculature, nerves, lymphatics
