9/9 Anatomy Lab Flashcards
Endothoracic Fascia
connective tissue in thorax; separates chest wall & diaphragm from parietal pleura; covers peaks of lungs. just inside the intercostal muscles along the interior of the thorasic wall.
Parietal pleura
sack surrounding the organs of the mediastinum, forms the lateral boundaries. Theparietal pleura covers the non-pulmonary surfaces within thethoracic cavity and extends morecaudally than the lungs. it is the bag around the lungs and extends down below them.
Costodiaphragmatic recess
the space caudal to the lungs that is still within the pleura, but extends down along the daiprham and rib cage.
costomediastinal recess
site where costal & mediastinal parietal pleura connect; anterior, near midline; exists only when lungs not completely filling pleura. This is infront of the lungs, and entails a little space between lungs and thorasic wall.
pleura space
space between the pleura sac that surrounds the lungs and the lungs themselves
visceral pleura
the inner membrane that directly encases and attaches to the lungs.
trachea
pathwya for air from the pharynx to the lungs (T4-T5 level)
carina
raised ridge of cartilage in sagittal plane; marks bifurcation of left & right primary bronchi at level of sternal angle (T4-T5 level). This is the ship’s hull of the brachia trunk
primary (main bronchi)
the main tube just inferior to the trachea
secondary (lobar) bronchi
branch from the primary bronchi to the different lobes of the lungs (3 on the right and 2 on the left)
Tertiary (segmental bronchi
branches from the secondary bronchi that then supply the bronchopulmonary segments.
Hilum and pulmonary ligament
the hilum is the entire collectio of vein/artery/bronchi/ that go in and out of the lung (it is the connective area of the lung). the pulmonary ligament is a inferior extension of the hilum, and serves for structue support.
Pulmonary arteries
the arteries that course into the lungs. on the left they are supperior, and on the right lung they are in the serperior to anterior location
pulmonary veins
the vessels that take oxygenated blood out of the lungs, they are located in the inferior location on the left lung and the inferior and a little anterior section on the right lung.
bronchi
the airways (this is the general term for the tubes that cary air to and from the lungs.
bronchopulmonary lymph nodes
these are the nodes of the lymph vessels that are located within the lungs usually at biforcations of the bronchial.
bronchial artery
Paired vessels to the lungs that project laterally from the aorta. The bronchial arteries carry oxygen-rich blood and supply the roots of the lungs
right lung
right side, this lung has 3 main lobes!
RL apex
the upper portion of the lung that pushes up into the neck above rib one.
RL Superior lobe
forms the anterior and superior portions of the right lung.
RL Horizontal fissure
these are invaginations of visceral pleura between the lobes of the lung. the horizontal is located between the superior and middle lobes.
RL middle lobe
the anteior and inferior portions of the right lungs. the smallest lobe and it is wedge shaped. (unique to the right lung)
RL oblique fissure
visceral pleura invagination between the middle and inferior lobes.
RL Inferior lobe
forms the posterior and inferior potions of the lung.
RL Base
the bottom of the right lung, on the diaphram
Left lung
int eh left pleural cavity, smaller that the right lung and only 2 lobes seperated by an oblique fissure, but it does have the lingula.
