Ear drum

43
Q

Inner Ear

A

Semicircular canals: balance
Cochlea: hearing

Saccule, Utricle = vestibular portions

44
Q

Semicircular Canals

A

fluid within allows you to know where you are at in space

45
Q

Thoracic Cavity

A

truncated cone
narrowest superior = ribs slant down
circumference increases inferiorly
maximum size at abdominal
floor made up by thoracic diaphragm

46
Q

Thoracic Cage includes

A

ribs
costal cartilages
supported by sternum and thoracic vertebrae
lower portion protects abdominal viscera

bony portion of thoracic wall

47
Q

Thorax

A

region between neck and abdomen
contains organs of respiratory & cardiovascular system
3 main spaces = mediastinum, right & left pulmonary

48
Q

Thoracic Wall

A

bony portion is thoracic cage
muscles that extend between ribs
skin, subcutaneous tissue, muscles, fascia

49
Q

Thoracic Cage purpose

A

protection of vital thoracic and abdominal organs from ext forces
resist negative internal pressures
support for weight of upper limbs
attachment of muscles to maintain UE position
attachment of muscles of abdomen, neck, back, respiration

50

External intercostal does

A

inspiration

51
Q

Internal intercostal does

A

forced expiration

52
Q

Abdominal Walls

A

contract to increase area
distend for accommodation
contains peritoneum

53
Q

Peritoneum

A

Serous memnrame
reflects and continues onto abdominal viscera
creates sac and peritoneal cavity
