Midclavicular: Rib 6
Midaxillary: Rib 8
Paravertebral: Rib 10
Inferior margin of parietal pleura in each line
Midclavicular: Rib 8
Midaxillary: Rib 10
Paravertebral: Rib 12
What does horizontal fissure (of right lung) follow?
Follows 4th rib anteriorly
What does oblique fissure (of both lungs) folllow?
Follows 6th rib anteriorly
Innervation of intercostal muscles
Anterior rami of thoracic spinal nerves
What type of epithelium is present in trachea and primary bronchi?
Pseudostratified columnar epithelium with goblet cells and cilia
Nerve supply of the pleurae
Parietal pleura: somatic nerve (pain sensitive)
Visceral pleura: autonomic nerves
