1
Trachea Slide No:3 Material: human trachea Method: H.E Naked eyes: its inner surface is mucosa hyaline cartilage is stained in dark blue, C-shaped ring of hyaline cartilage
2
Under lower power, the wall of trachea is divided into three layers: mucosa, submucosa, adventitia
4
High power: Epithelium, laminar propia, basal laminar
5
Serous acinus mixed acinus Mucous acinus
6
chondroblast, chondrocyte, isogenous groups
Cartilage lacuna and cartilage capsule
7
Lung Slide No:31 Material: human lung Method: H.E Conducting portion Small bronchi: Large lumen; pseudostratified columnar ciliated epithelium; glands; imcompleted cartilage rings
8
Bronchiole: smaller lumen; thiner wall; epithelium transition; glands and cartilage; smooth muscle
9
Terminal bronchiole: smaller lumen; thiner wall; simple ciliated cuboidal epithelium; no gland; no cartilage; a completed layer of smooth mucle
10
incompleted wall; ciliated cuboidal epithelium.
Respiratory portion: Respiratory bronchiole: incompleted wall; ciliated cuboidal epithelium.
11
Alveolar duct: Smooth muscle knobs
12
Alveolar sac alveoli
13
Dust cell: Macrophage Dust in the cytoplasm
15
Cortex, cortical labyrinth, medullary rays
Kidney Slide No:32 Material: human kidney Method: H.E Cortex, cortical labyrinth, medullary rays medulla
16
Renal corpuscle: glomerulus, renal capsule, the parietal layer,The visceral layer
17
Proximal convoluted tubule: simple cuboidal epithelium
large, brush border strongly acidophilic cytoplasm no clear boundary
18
Distal convoluted tubule: simple cuboidal epithelium
flatter and smaller less acidophilic
19
Justaglomerular complex: Macular dense
20
Collecting tubule: simple cuboidal or columnar epithelium
the cells stain weakly by the usual stains clear boundary
22
Medulla: thin segment: simple squamous epithelium
