Test 1 Flashcards
Rib Cage
Structure ribs, sternum, vertebrae
Rib pairs?
12, connected to sternum
2 False, connected to cartilage and lowest 5th rib
2 floating ribs, connect to spine
Intercostal muscles
External, farthest outside, expand rib cage when inhaling.
Diaphragm
A dome that separates chest cavity from viscera, pulls central tendon, divides chest from abdominals.
Sternum
3 parts: (top to bottom)
Manubrium
Body
Xiphoid Vertebrae
Clavicle
Serves as strut between shoulder blade, sternum, and breast bone.
Epigrastrium
Part of upper abdomen, immediately over stomach.
Thoracic cavity
Contains medastrium & 2 plural cavities -known as chest cavity.
Trachea
Wind pipe, discs leading up to larynx
Abdominal cavity
Contains lower part of esophagus, stomach, small intestines, kidneys…etc
Lungs
The power source in the
Power -> Vibrator -> Resonator
Bronchi
Little Pulips at trachea and down, gradually gets smaller.
Main stem bronchi
2 left lobar bronchi
3 right lobar bronchi
S/Z ration
Air flow compared when exhaling by a non-phonated and phonated consonant.
Larynx
1 bone, 6 cartilages, 5 intrinsic muscles, 11 extrinsic, 4 spaces
Epiglottis
Folds over glottis when eating to prevent choking.
(Elastic Cartilage)
Ex: “fuck, my epiglottis just falted and now their is corn in my trachea”
Thyroid cartilage
Two fused Laminae, protects vocal folds, 2 superior Cornu, 2 inferior, articulation for muscles.
Back side = anterior commisure
(hyaline)
Cricoid Cartilage
Top BONE
supports the rest of the larynx, consist of Laminae and ring.
Function: attached to first tracheal ring, articulation for muscles.
Arytenoid cartilages
“Wings” within larynx
Body, greater horns, lesser horns(tubercle)
Function: swallowing, structure, muscle articulation
(Hyaline cartilage)
Corniculate cartilages
Tips of wings, paired
1 = cornicle.
Prolongs Arytenoid cartilage, situated in arypeglottic folds.
(Hyaline cartilage)
Cuneiform cartilages
Floating, paired, wedge shaped
Hyaline
Hyoid Bone
Bone on top
Function: swallowing, muscle art, structure
False vocal folds (ventricular folds)
Outside of vocal chords
Ventricle
Space between true and false folds
Vestibule
Space above false folds
