27
Q

Contraction of the accessory muscles of inspiration increase the volume of the thoracic cavity in the ________________ dimension.

A

transverse

28
Q

An increase in thorax volume will cause a(n)

_________________ in alveolar pressure.

A

decrease

29
Q

Compression of the ____ will result in reduction of lung volume.

A

abdomen

30
Q

Contraction of the diaphragm increases the volume of the thoracic cavity in the ________________ dimension.

A

vertical

31
Q

When the diaphragm contracts, the central tendon is pulled in which direction?

A

inferiorly and anteriorly

32
Q

Surfactant is a mucous which serves the lungs by: (3 things)

A

promoting inflation, enabling smooth movement, & lowering surface tension

33
Q

The primary role/s of the muscles of the thorax, back, and upper limbs include: (2 things)

A

head control & trunk control

34
Q

This muscle originates at the posterior abdominal wall at the vertebral column, courses laterally, and inserts in the transversus abdominis aponeurosis and inner surface of ribs 6-12. Contraction will compress the abdomen.

A

transverse abdominis

35
Q

This muscle originates at the inguinal ligament/iliac crest, then fans medially to insert in the cartilaginous portion of the lower ribs and abdominal aponeursis. It serves to rotate and flex the trunk, and compress the abdomen.

A

internal oblique abdominis

36
Q

This muscle originates at the osseous portion of the lower 7 ribs, then fans downward to insert at the iliac crest, inguiinal ligament, and abdominal aponeurosis.

A

external oblique abdominis

37
Q

This muscle originates as 4 or 5 segments at pubis inferiorly, courses up to segment border, to insert at the xiphoid process and the cartilage of ribs 5-7.

A

rectus abdominis

38
Q

This muscle originates in the inferior surfaces of ribs 1-11, and courses down, to insert in the upper surface of the rib immediately below, and serves to elevate the rib.

A

external intercostal

39
Q

This muscle originates in the spinous processes of C7 and T1-T3, courses down and laterally, to insert just beyond the angles of ribs 2 through 5.

A

serratus posterior superior

40
Q

This muscle originates in the sternum and clavicle, courses in a fanlike lateral direction to converge at the humerus, and serves to elevate the sternum.

A

pectoralis major

41
Q

This muscle originates in the transverse process of T7 through T11, courses down and obliquely out, to insert two ribs below the site of origin, and serves to elevate the rib cage.

A

levator costarum longis

42
Q

Twisting of a shaft while one end does not move

A

torquing

43
Q

The volume of air exchanged during one cycle of respiration

A

tidal volume

44
Q

Feeling of a structure using one’s hands

A

palpation

45
Q

The process of moving two structures further apart

A

abduction

46
Q

Pressure generated as a result of the weight of atmospheric pressure

A

atmospheric pressure

47
Q

The volume of air that can be inspired after a tidal inspiration

A

inspiratory reserve volume

48
Q

Using the muscles of inspiration to impede the outflow of air during expiration

A

checking action

49
Q

The combination of inspiratory reserve volume, expiratory reserve volume, and tidal volume, representing the capacity of air available for speech

A

vital capacity

50
Q

Device that measures pressure

A

manometer

51
Q

Device that measures volume of expelled air

A

spirometer

52
Q

Having the ability and tendency to return to original position

A

elasticity

53
Q

Tube-like device that permits observation within the body

A

endoscope

54
Q

The ability of a material to resist being pulled apart

A

tensile strength
