1.1.1 Cell Biology and Histology of Respiratory System Flashcards
Where is the olfactory area in the nasopharyngeal cavity?
Which mitotically active cells produce neuronal cells throughout life?
Basal cells of the olfactory epithelium
The axonal projections of olfactory epithelium project from which portion of the cell to what region of the brain?
Basal region and contacts neurons of the olfactory bulb in the brain
What protein secreted by olfactory glands binds odorants? What do plasma cells in this region secrete?
Olfactory Binding Protein (OBP); IgA
What are the two functional components of the respiratory system?
Conduction Sytem
Respiratory System
What is the respiratory system comprised of?
Pulmonary acini consisting of respiratory bronchioles, alveolar ducts, alveolar sacs, and alveoli
Describe the flow of blood from the R ventricle through the lungs and body until it returns to the R atrium.
Describe the positioning of the trachea, larnyx, pharnyx, and bronchi.
Pharnyx, Larnyx, Trachae, Bronchi
What structure terminates at the respiratory bronchioles and gives rise to the alveolar capillary plexus?
Pulmonary artery
What is the conduction system comprised of?
Nasal and oral cavities to terminal bronchioles
What do each of the letters represent?
C: Hyaline cartilage
M: mucosa
T: trachealis muscle
L: longitudinal muscle
What do each of these letter represent in this cross section of the trachea?
E: Respiratory epithelium
LP: Lamina propria
SM: Submucosa
F: Fibroelastic Tissue
Describe the specific components of the respiratory system starting with nasal and oral cavities to the respiratory bronchioles.
At what level traveling deeper into the respiratory system, does hyaline cartilage stop playing a role in its structure?
The bronchiole
What are the structures numbered 1-3?
