Q

What is the location fof the larynx?

A

it connects the pharynx to the trachea

24
Q

What is the function of the Larynx?

A 
conducts air
Produces sound (voicebox)
25
What type of tissue is located in the Larynx?
Non Keratiniezed stratified squamous | Pseudostratified ciliated columnar
26
what type of cartilage is located in the Larynx?
1. Thyroid cartilage 2. Cricoid cartilage 3. Epiglottis
27
what are the characteristics of the Thyroid Cartilage?
Largest - Anterior and lateral walls No posterior portion
28
What are the features of the Thyroid Cartilage?
Thyrohyoid membrane: connection of thyroid cartilage to the hyoid bone Laryngeal prominence: pointy part of the anterior portion of the thyroid cartilage (adams apple)
29
characteristics of cricoid cartilage?
complete c ring shaped | inferior to the thyroid cartilage
30
what is the feature of the cricoid cartilage?
Cricothyroid ligament: connects the cricoid and thyroid cartilge
31
Characteristics of the Epiglottis ?
Spoon shaped projection into pharynx | Elastic cartilage so it can bend and snap
32
what is the fucntion of the epiglottis?
- Function: choking prevention | Epiglottis bends and covers the trachea pushing the food down the esophagus
33
What are the minor cartilage of the larynx?
1. Arytenoid cartilage 2. Corniculate cartilage 3. Cuneiform cartilage
34
Arytenoid Cartilage
Superioposterior cricoid - Attaches to thyroid cartilage --> vocal ligament --> vocal folds Looks like a boot Vocal ligament connects to the thyroid cartilage, membrane over it called the vocal fold
35
Corniculate Cartilage
Attached to arytenoids - Attaches to thyroid cartilage--> vestibular ligament - vestibular folds :Vestibular folds: are false/fake vestibular ligaments
36
Cuneiform Cartilage
Supports aryepiglottic fold | Supports fold from arterynoid cartilage
37
Range of sound production?
Length and thickness of vocal cords Long or thick = deep Short or thin = high
38
Pitch of sound production?
- Tension - Increased tension = high pitch - Decreased tension = low pitch Manipulate the pitch of voice with increase or decrease of tension
39
Loudness of sound production?
depends on the amount of air
40
location of the trachea
- Inferior to larynx | - Anterior to esophagus
41
Tracheal Cartialge?
c shaped , opening of the c is on posterior side, they are connected by anular ligament C shape allows for different size of foods
42
Anular Ligament?
Anular ligament connects tracheal cartilages all the way around
43
Trachealis muscle
at the opening of the C , connects the ends of C
44
What type of tissue is found in the Trachea ?
: pseudostratified ciliated columnar
45
what are the bronchi?
Highly branched conducting system within lungs
46
Right Primary Bronchi?
Wider, Divides to 3 secondary bronchi
47
Left Primary Bronchi?
Divides to 2 secondary bronchi
48
Branching progression
- Smaller - Decreased cartilage - Increased smooth muscle
49
types of tissues in bronchi branches
pseudostratified ciliated columnar -->simple columnar --> simple squamous
50
Structure of Bronchioles
- 1mm diameter (small) - Thick layer of smooth muscle - Bronchoconstriction - Bronchodilation > forms terminal bronchioles: last portion of conduction
51
Respiratory portion of bronchioles
- Respiratory bronchioles > Alveolar duct > Pulmonary alveoli Some exchange occurs in the respiratory bronchioles Alveolar ducts : turn into pulmonary alveoli
52
What are the Alveolus
thin walled sacs
53
alveolus cells
Alveolar type 1 and Alveolar type 2
54
ALveolar type I
Make up the sac Simple squamous Thin for rapid diffusion
55
Alveolar type II
Simple cuboidal with extensions Not as many as type 1 Pulmonary surfactant: substances that decrease surface tension. Prevent the lungs from collapsing
56
gas exchange
Pulmonary: movement of air in/out of the lung - External: alveoli to capillaries:air into the lungs to the alveoli capillaries out - Internal: capillaries to cells
