Respiratory Anatomy Flashcards
Notches on manubrium
Jugular (superior) and clavicular (lateral and superior)
Sternomanubrial joint
Secondary cartilaginous
Sternal angle
T4
Xiphoid process
Most inferior part of sternum, T10
Manubrium
superior part of sternum
True ribs
1-7 (vertebrosternal)
False ribs
8-10 (vertebrochondral)
Floating ribs
11-12 (vertebral)
Features of a typical rib (3-9)
Tubercle (articulates with transverse process), head/neck (articulates with vertebral bodies above and below), rounded superior border of rib, sharp inferior border, the angle, costal groove (contains intercostal nerves and bundle), site of articulation with costal cartilage
Costal groove
Groove in rib containing intercostal nerves and vessel
The 1st rib
Atypical rib that is short, flat and wide. Only articulates with T1. Contains head/neck (articulates with T1), tubercle (articulates with transverse process), groove for subclavian artery (posterior), scalene tubercle (for connection of anterior scalene muscle) and groove for subclavian vein (anterior)
Vertebral foramen
Opening in vertebral bodies for spinal cord and meninges
Transverse process of vertebral body
Articulates with tubercle of rib
Thoracic inlet
T1, 1st pair of ribs and manubrium
Thoracic outlet
T12, 11th and 12th pairs of ribs, costal cartilages 7-10 and xiphisternal joint
Intercostal muscles
External intercostals, internal intercostals and innermost intercostals
Neurovascular bundle
Runs between internal and innermost intercostal muscles. Contains intercostal vein, intercostal artery and intercostal nerve
