24
- dorsal portion of the pharynx that communicates with the nasal cavity? - separated by the soft palate from oropharynx
NASOPHARYNX
25
L.E. of NASOPHARYNX
TRE
26
L.P. of NASOPHARYNX
- loose or areolar CT - DLT AND NLT - branched tubuloalveolar mucous, serous and mixed glands
27
M.M. of NASOPHARYNX
ABSENT
28
T. ADVENTITIA of NASOPHARYNX
TYPICAL
29
a short irregularly shaped muscular tubular organ supported by hyaline and elastic cartilage joined by connective tissue
Larynx
30
L.E. of LARYNX?
false vocal cords - TRE true vocal cords - stratified squamous ep. nonkeratined
31
-connects the larynx and the extrapulmonary bronchi - with C-shaped hyaline cartilage rings and a muscle that connects the cartilage
TRACHEA
32
L.E. OF TRACHEA?
TRE
33
- connects the trachea and the lung - similar structure to trachea
Extrapulmonary primary bronchus
34
It expands the alveoli
Surfactant
35
Cartilage, connective tissue and muscles of the lung are derived from mesenchymal cells from?
Splanchnic mesoderm
36
L.E. of intrapulmonary primary bronchus?
TRE?
37
same in structure as primary bronchus except: smaller diameter - cartilage in the t. muscularis is made up of large plates separated by gaps filled with loose CT and smooth muscle
Secondary bronchus
38
part of the bronchial tree where the actual exchange of gases occurs
Respiratory portion
39
- expandable structure -enveloped by visceral pleura (DWFCT with mesothelium) - divided into lobes
LUNGS
40
branch of respiratory bronchiole that gives off to peripheral branches: alveoli
Alveolar duct
41
- dead end of the respiratory region - round or polygonal structure with irregular lumen and a folded wall entirely formed by alveoli
Alveolar sac
42
functional unit of the lung
Alveolus/i
43
- more common - typical squamous with oval nucleus bulging into lumen of the alveolus
Type 1 pneumocyte
44
- less frequent - polygonal or low cuboidal with round nuclues and granular cytoplasm - produces surfactant
Type 2 pneumocyte
45
In mouse?
Type 3 pneumocyte
46
Olfactory region is absent in some avian species like chicken. (T or F)
True
47
Syrinx in avian is the equivalent of T and F vocal cords in mammals
True
48
Lung is small and expandable in Avian respiratory system
False IT IS UNEXPANDABLE AND ADHERES TO THE RIB CAGE
49
Avian respiratory system has 7 air sacs that shuffle air around not for exchange of gases
FALSE 9 AIR SACS
50
- Short and expands to form the vestibulum | AVIAN
Intrapulmonary bronchus
51
- short expanded tube - continuous as a mesobronchus - connected to the abdominal air sac | AVIAN
Vestibulum
52
- lined with TRE with cartilage and smooth muscle in the walls - gives rise to recurrent secondary bronchi
Mesobronchus
53
- corresponds in the respiratory bronchiole in mammalian lung
Secondary bronchus
54
- corresponds to the alveolar ducts of mammals - interconnects with secondar bronchi to form a complete air conducting loop
Tertiary or Parabronchus
55
- corresponds to the alveolar sac of mammals - wall gives off tiny spaces called air capillaries which is the s ite for gas exchange | AVIAN
Air vesicles
56
- corresponds to the alveolus of mammals - projects as tiny space from the wall of air vesicle closely adjacent to blood capillaries
Air capillaries
57
- thin membranous structures - occur free in the body cavities and send diverticula into the bones (pneumatic bones)
Air sac
58
- partial persisitence of laryngotracheal groove
Tracheosophageal fistula
59
- lack of production of pulmonary surfactant (temporary)
Barker foal syndrome: hyaline disease
60
- failure of closure of one or both pleuroperitoneal folds
Pleuroperitoneal hernia
61
- central weakness in the central tendinous part of the diaphragm
Peritoneopericardial diaphragmatic hernia
62
L.E. of FALSE vocal cords?
TRE
63
L.E. of TRUE vocal cords?
Stratified squamous epithelium non-keratinized
64
Smooth myocytes that connects the cartilages ont he dorsal portion of the trachea?
Trachealis muscle
65
In pig and ruminants, their brochial tree of the right lung gives off a branch called?
Tracheal bronchus
66
Terminal branches?
Alveolar sacs
67
Position of lungs in very young embryos?
dorsal to the heart
68
Position of lungs in older embryos?
Dorsal to the heart and liver
69
Eventually the lungs expand laterally and ventrally?
Lateral to the heart
