|
What covers the vestibular folds?
|
Respiratory epithelium
|
|
|
What is the vocal liganmetn?
|
The dense ligament assoiciated with the ....
More superfical than vocalis muscle |
|
|
Are there c shaped rings of cartillage in the bronchi?
|
Negator
|
|
|
How does the epithelium change as you enter the bronchioles?
|
More cuboidial, goblet cells disapear.
Smooth muscle rather than hyaline cartilage plates |
|
|
What do clara cells secrete?
|
Glycosaminoglycans. A psedu surfacant
|
|
|
Can clara cells divide?
|
Yes they can. Nate said its cool.
|
|
|
What makes up the conducting portion of the respiratory epithelium?
|
Ciliated pseudostratified columnar epithelium.
-Ciliated cells + mucous cells + brush cells + small granule cells + basal cells. |
|
|
What lines the nasal vestibule?
|
lined by nonkeratinized strat. squam. epithelium
|
|
|
Where are vibrissae located?
|
Tiny hairs in vestibule to filter out particles.
|
|
|
Where are the serous mucos glands of the vestibule located?
|
vascular lamina propria (loose connective tissue)
|
|
|
What makes up the olfactory epithelium?
|
a variation of ciliated pseudostratified columnar) contains olfactory cells, supporting (sustentacular) cells, and basal cells.
|
|
|
What kind of neurons are olefactory cells?
|
Bipolar neuron
|
|
|
Describe odor receptors.
|
very long, nonmotile cilia - extend over the olfactory epithelium surface
|
|
|
Which is thicker respiratory or olefactory epithelium?
|
Olfactory
|
|
|
What will you find in the Lamina propria (loose CT) of the olfactory region?
|
Lamina propria (loose CT) has many veins & unmyelinated nerves and Bowman's glands (fairly serous).
|
|
|
What do Bowman's capsules do?
|
produces watery secretion. Released onto the olfactory epithelium via ducts.
(1) Odorous substances dissolved in secretions detected by olfactory cilia. (2) Secretions flush surface & prepare the odor receptors to receive new stimuli. |
|
|
What nasal feature does Afrain and sudafed have an effect on?
|
Venous plexus
|
|
|
What makes up the mucous membrane of epiglottis?
|
consists of the epithelium, lamina propria (loose CT) and glands
|
|
|
What is on the lingual and apical laryngeal surfaces and respiratory epithelium on the lower laryngeal surface.
|
Stratified squamous nonkeratinized epithelium
|
|
|
What is in the lamina propria of the epiglottis?
|
muco-serous glands and elastic cartilage
|
|
|
Describe the respiratoy folds?
|
also called false folds) Lie superior to vocal cords. Folds of loose connective tissue containing glands, lymphoid aggregations, & fat cells. Covered by respiratory epithelium
|
|
|
What is the epithelium of the vocal folds?
|
covering of stratified squamous nonkeratinized epithelium
|
|
|
What makes up the vocal folds?
|
consist of skeletal muscle (vocalis muscle), vocal ligament (band of elastic and collagen fibers),
|
|
|
What makes up the conducting portion?
|
1) Trachea
2) Primary Bronchi 3) Secondary Bronchi 4) Tertiary Bronchi 5) Bronchioles 6) Terminal Bronchioles |
|
|
What makes up the respiratory portion?
|
1) Respiratory bronchioles
2) Alveolar duct 3) Alverolar sac 4) Alveolus |
|
|
Where do the primary bronchi arise from?
|
Primary Bronchi arise from subdivisions of the trachea
|
|
|
What are the characteristics of the bronchi?
|
Irregular plates of hyaline cartilage
Respiratory epithelium in bronchi Muco-serous glands |
|
|
Where is the cartillage in the bronchioles?
|
Trick question there isnt any.
|
|
|
Describe bronchioles?
|
Epithelium varies from ciliated columnar or cuboidal with goblet cells
Walls have smooth muscle rather than hyaline cartilage plates. Lack glands in submucosa. Small diameter Surrounded by lung tissue |
|
|
Describe terminal bronchioles
|
Generally simple cuboidal epithelium - contains mostly Clara cells, some ciliated cells maybe
No goblet cells Smooth muscle and some elastic fibers present **Walls of terminal bronchioles are continuous** |
