-
Teeth:
incisors
premolars
molars
- teeth grow continuously throughout life
- incisors - self sharpening
-
Hard and Soft Palate
- hard palate with rugae
- separate nasopharynx and oropharynx (secondary palate)
-
Epiglottis
- between tongue and larynx
- prevents food from entering larynx
-
larynx
- "voice box"
- anterior end of trachea
- 9 cartilages *homologous to visceral arch cart. 4-6
- connects pharynx to trachea
- breathing, sound production and protecting trachea from food
-
thyroid cartilage
- visc. arch 4 and 5
- "Adam's Apple"
- ventral and lateral walls (anteriorly)
-
cricoid cartilage
- lateral and dorsal walls (posteriorly)
- visc arch 6
-
arytenoid cartilages
- anterior to dorsal part of cricoid
- small, triangular
- visc arch 6
-
vocal cords
lateral folds between arytenoid and thyroid
-
glottis
- small, slit-like opening to larynx
- closed unless inhale/exhale
-
trachea
- "windpipe"
- posteriorly from larynx to lungs
- tracheal rings present (visc arch 7) - prevent collapsing
-
lungs
- cranial, middle, and caudal lobes on both sides
- 7th accessory lobe on the right side (from further division of the posterior/caudal lobe)
-
pulmonary ligament
mesentary anchoring lungs to wall of pleural cavity
-
mediastinum
space within mediastinal septum containing the heart, esophagus, trachea, nerves, blood vessels, etc
-
How does the trachea split in the lungs?
(bronchial tree)
- principal bronchus
- segmental bronchus
- numerous bronchioles
- passages terminate in pulmonary alveoli
-
diaphragm
- muscular
- separates thoracic and abdominal cavities
