Links and models to check out...
Degrauw's Biology page..The link was Waaaaaaayyyyy back on the 2nd post.
The fabulous practice questions
What to find or know function on the practical quiz:
Upper respiratory structures:
Oral cavity-
Hard Palate- bone structure superior to teeth
Soft Palate- soft tissue behind hard palate which extends to uvula
External Nares- opening of nose
Nasal Cavity- nose internal area
Nasal Septum- divides right and left cavities
Nasal Conchae- tissue wrapped around turbinate bones
Turbinate Bones- bones in nose covered with tissue to assist in mixing, warming, filtering and humidifying air
Internal Nares- Internal Nasal cavity
Nasopharynx- Nose area to uvula
uvula- continuation of soft pallate
Pharyngeal Tonsil- in posterior nasal cavity
Oropharynx- Uvula to larynx
palatine tonsil- near Uvula
Phayngeal tonsil- in posterior nasal cavity
Larynx-
Hyoid bone- under chin, bone unconnected
Thyroid Cartilage- Of larynx inferior to hyoid largest piece of cartilage
Arytenoid Cartilage- internal thyroid cartilage posterior to vocal cords
Cricoid cartilage- Inferior to thyroid
Thyrohyoid ligament (membrane) between hyoid and thyroid
Cricothyroid ligament- between cricoid and thyroid
Epiglottis- flexible elastic cartilage superior to larynx opening- closes off respiratory system from esophagus
Glottis
Vestibular Fold- "false vocal" skin folds over vocal cords
Vocal fold- true vocal cords more string-like in appearance
Our models from class- can you identify??
Another Model you can count on seeing
Lower respiratory Structures:
Trachea-
trachealis muscle- smooth muscle through trachea
Tracheal rings- cartilagenous rings "C" shaped
Tracheal Bifurcation
Carina- special C shaped cartilage
Hilus- point where bronchi, blood vessels and nerves enter the lungs
Primary Bronchi-
Secondary Bronchi-
Lobes of the Lung- 2 left lobes and 3 right lobes
Cardiac Notch- impression of heart into left lung
Diaphragm-
Visceral Pleura- The viscera of the lungs folds upon itself at the hilus to for the parietal fluid. It is filled with parietal pleura
Parietal Pleura-
The respiratory zone (as opposed to prior conducting zone)
Respiratory bronchioles allow the first air exchange
