Respiratory Histology Lab Flashcards
This is olfactory epithelium. Name the three cell types circled and the structure circled in black.
Basal cells are circled in blue [short, with nuclei near basement membrane]
Olfactory cells [aka bipolar neurons] are circled in red [centrally located nuclei]
Substentacular cells [nuclei are near apex] are circled in black
Bowman’s capsule is circled in black
What type of epithelium is this? Name the cells circled and the structures pointed to
Circled cells = goblet cells
Arrow to cilia
RESPIRATORY EPITHELIUM
What structure is this?
Epiglottis
This is epiglottis. What types of cells are these and what side are they on.
Stratified squamous; lingual side
This is the epiglottis. What types of cells are these and what side are they found on.
Pseudostratified ciliar columnar - found on pharyngeal side
This is the lamina propria of the epiglottis. Named the circled structures.
Mucous in blue and serous in red
Which are the true and false vocal cords of the larynx and how can you tell
The true vocal cords are on the left - they contain muscle and if zoomed in would have stratified squamous epithelium
The false vocal cords are on the right - they contain seromucous glands and if zoomed in would have respiratory epithelium
What laryngeal structure is this?
False vocal cord - evident by the seromucous glands and the respiratory epithelium [pseudostratified columunar]
This is the covering of a vocal cord. Which type of vocal cord is it?
It is a true vocal cord because it is covered with stratified squamous eptihelium
What structure is this in the epiglottis
trachealis muscle
This structure is in the trachea
hyaline cartilage
What is this structure in the trachea
trachealis muscle
These are the layers of the trachea. describe them.
blue cells are goblet cells in respiratory epithelium. hyaline cartilage area is pink with blue cells. seromucous glands are in white
Describe the layers of the trachea from top to circled structures
Adipose cells, trachealis muscle, hyaline cartilage [pink with blue cells] and seromucous glands in white
This is in the trachea. What type of epithelium is this and how can you tell?
Respiratory epithelium see goblet cells
pseudostratified columnar
This is a bronchus. What is the circled structure?
What structures are contained within the submucosa [not seen here]?
cartilage plate
seromucous glands
is this a brochus or a bronchiole. how can you tell.
bronchiole
no cartilage plates
no seromucous glands
What are these
alveolus
What types of cells are these.
On the left is a type 1 alveolar cell (squamous)
On the right is a type 2 alveolar cell (cuboidal)
What types of cells are these
On the left are type II alveolar cells[cuboidal]
On the right are type I alveolar cells [squamous[
pulmonary artery
alveolar duct
alveolar cells
blue = type II
red = type I [squamous]
Dust cells
bronchial artery
bronchial artery
Name these structures
T,F,E
t=true vocal cords
f= false vocal cords
e= epiglottis
these are found on epithelium of respiratory airways
clara cells- bronchiole
Name structures
TEM containing lamellar bodies[full of surfactant yay]
What is this? Name structures
Interalveolar septum
B= fused basal lamina
P = type I pneumocytes
E = capillary endothelium
A = alveolar air space
