Cards

Term
Another name for nasal nerve bundles
Definition
filia olfactoria
Term
Structure through which olfactory nerves must pass through to reach the olfactory bulb of the brain.
Definition
Cribriform plate
Term
What is the role of Bowman's glands in the nose?
Definition
Secretes a material which solubilizes odor molecules so that olfactory cells can sense them.
Term
In the olfactory mucosa, these cells have nuclei close to the surface.
Definition
Supporting cells
Term
In the olfactory mucosa, these cells have nuclei low in height.
Definition
Basal cell
Term
In the olfactory mucosa, these cells have nuclei that are pretty much in the center of the mucosa.
Definition
Olfactory cells
Term
Connects pharynx with trachea.
Definition
Larynx
Term
These muscles move cartilage of the glottis to produce vibrations/tension from passing air.
Definition
Vocalis muscles
Term
A "group name" consisting of the vocal folds and the space between them in the larynx.
Definition
Glottis
Term
Space just above the glottis.
Definition
Ventricle
Term
This area in the larynx is involved in voice resonance.
Definition
Ventricular (false) vocal fold
Term
This epithelial type is seen on the surface of the larynx.
Definition
stratified squamous epithelium
Term
location of trachea glands within the trachea
Definition
submucosa
Term
entroendocrine cells of the respiratory system that can produce local signaling factors, peptides etc.  Role is not well known in trachea
Definition
Small granule cells
Term
The bronchiole division just before entering the respiratory region from the conducting region of the respiratory system.
Definition
Terminal bronchioles (eventually lead to respiratory bronchioles)
Term
Pathway of air through respiratory system from the outside of the body.
Definition

Nose

pharynx

larynx

trachea

primary bronchi (extrapulminary bronchi)

lobar bronchi

segmental bronchi

larger bronchioles 

terminal bronchioles

respiratory bronchioles

alveolar ducts

atria

alveolar sacs

alveoli

Term
Surrounds all bronchi
Definition
adventitia and cartilage
Term
This cell type is 80% of terminal bronchioles and it secretes surficant to prevent luminal adherence causing bronchiolar collapse.
Definition
Clara cells
Term
A common, shared opening between alveolar sacs.
Definition
Atria
Term
very thin cells in the alveoli that allow gas diffusion.
Definition
small epithelial cells (pneumocyte type I)
Term
Produces a non-protein surficant in alveoli allowing them to expand against a reduced surface tension.
Definition
Great alveolar cells (pneumocyte type II)
Term
Structures in type II pneumocytes that hold and eventually release surfactant.
Definition
multi-laminar bodies.
Term
A premature infant has great difficulty breathing.  What is the reason?
Definition
Surficant is produced late in gestation; suffering from infant respiratory distress as a result.
Term
A common cause of adult respiratory distress.
Definition
Lung capillaries leaking due to pulmonary edema often seen in CHF.
Term
Phagocytes of the respiratory system that originate from monocytes.
Definition

Dust cells

 

NOTE: Dust cells in smokers have lots of residual bodies; vaccules in them that do not digest.

Term
A disorder caused by progressive decreased elasticity and destroyed alveolar sacs.  Also increased mucus and inflammation which can cause obstructions.
Definition
COPD (progressive)
Term
Disease caused by increased mucus and inflammation which can cause obstructions.
Definition
Chronic obstructive bronchitis (a part of COPD)
Term
Disease caused by alveoli losing their shape, becoming to large and generally appearing floppy and unable to efficiently perform gas exchange.  Alveoli are ultimately destroyed.
Definition
Emphysema (a part of COPD)
Term
A disease caused by many pathogens characterized by lots of RBCS, WBCs and fibrin in alveoli, engorged capillaries, hepatization, and decreased gas exchange.
Definition
Pneumonia 
Term
Disease of thick mucus production which causes obstructions.  The etiology is a dysfunctional Cl- transporter.
Definition
Cystic fibrosis
Term
The 4 classes of mutations in cystic fibrosis
Definition

I. Premature gene termination

II. degradation of functional protein

III. Not responsive to regulation

IV. In membrane, but faulty
