21
Q

Pump handle movement

A

Inspiration resulting in the upper ribs moving sternum anteriorly and superiorly resulting in increase of anterior and posterior diameter of the ribs.

22
Q

Bucket handle movement

A

During inspiration the angle of the lower ribs, indirect attachment of 8-10 ribs to sternum through 7th rib result in increasing the transverse diameter.

23
Q

myotome

A

a group of muscles which is innervated by single spinal nerve root

24
Q

intercostal nerve

A

are the somatic nerves that arise from the anterior divisions of the thoracic spinal nerves from T1 to T11. These nerves in addition to supplying the thoracic wall also supply the pleura and peritoneum.

25
Q

What forms the thoracic wall?

A

formed by 12 ribs, 12 thoracic vertebrae, cartilage, sternum, and five muscles (external intercostal muscles, internal intercostal muscles, innermost intercostal muscles, subcostalis, and transversus thoracis)

26
Q

Costocervical trunk

A

a branch of the subclavian artery which supplies the upper extremities and contributes partly to the blood supply of the head and neck. (Superior portion)

27
Q

Where does the supreme intercostal a. branch from?

A

branches from the costocervical trunk

28
Q

Posterior intercostal a.

A

branches from aorta and it supplies blood to the posterior portion. Extends anteriorly, lying within the costal groove of the rib above and accompanied by a vein superiorly and a nerve inferiorly

29
Q

Internal thoracic a.

A

Branches from the subclavian a. and supplies the anterior side

30
Q

What arteries branch from the internal thoracic a.?

A

Anterior intercostal a., Musculophrenic a., Superior epigastric a.

31
Q

Mnemonic for Axillary Artery breakdown

A

Screw The Lawer Save A Patient: (Superior thoracic a., Thoracoacromial artery/trunk, Lateral/long thoracic artery, Subscapular artery, anterior circumflex humeral artery, Posterior circumflex humeral artery)

32
Q

What artery does the axillary artery branches from?

A

Subclavian a.

33
Q

Brachiocephalic vein branches to what veins?

A

Internal thoracicvein/superior intercostal vein

34
Q

Azygos vein

A

the azygos vein is a unilateral vessel that ascends in the right posterior mediastinum along the right border of the inferior eight thoracic vertebrae

35
Q

External intercostal membrane

A

found within the intercostal spaces of the costal cartilages, where it extends from the sternal ends of the ribs to the anteromedial ends of the intercostal spaces

36
Q

posterior intercostal membrane

A

thin aponeurosis that arises from the posterior end of the internal intercostal muscles.

37
Q

Diaphragm

A

primary inspiratory muscle. Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges. This contraction creates a vacuum, which pulls air into the lungs Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges. This contraction creates a vacuum, which pulls air into the lungs

38
Q

inspiration

A

the process of taking air into the lungs. It is the active phase of ventilation because it is the result of muscle contraction

39
Q

expiration

A

The second phase is called expiration, or exhaling. When the lungs exhale, the diaphragm relaxes, and the volume of the thoracic cavity decreases, while the pressure within it increases

40
Q

pleural cavity

A

between 2 layers of pleura, separated right and left lungs, lubrication

41
Q

mediastinum

A

a space in your chest that holds your heart and other important structures. It’s the middle section of your thoracic cavity, between your left and right pleural cavities

42
Q

serous membrane

A

thin layers of tissue that line body cavities and organs. In short, they excrete lubricating substances that allow organs and structures to slide over one another

43
Q

3 lobes of the lung

A

superior, middle, inferior

44
Q

2 fissures of the lung

A

oblique fissure and horizontal fissure

45
Q

Oblique fissure

A

separating superior and middle from inferior lobes

46
Q

Horizontal fissure

A

separating the superior from the middle lobe

47
Q

Hilum

A

the space where vessels and nerves pass from your bronchus to your lungs

48
Q

Bronchi

A

carry air to and from your lungs

49
Q

trachea

A

air passageway

50
Q

alveoli

A

where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out, and it has a single layer of specialized epithelia
