PHARYNX
PHARYNX
These are the three sections of the Nasal conchae
What is Superior -Middle -Inferior
This is the largest shield-shaped structure (Adam's apple)
What is the Thyroid cartilage
Located at the top, separated from the middle lobe by the horizontal fissure and from the lower by the oblique fissure.
What is the Right Upper Lobe
The main, rigid, cartilage-ringed tube that carries air from the larynx toward the lungs.
What is the Trachea
A dome-shaped sheet separating the chest from the abdomen.
What is the Diaphragm
The tongue is located here
What is the oral cavity
It sits below the thyroid cartilage, acting as the base of the larynx
What is the Cricoid Cartilage
Smallest lobe, located between the horizontal and oblique fissures.
What is the Right Middle Lobe
The tube that splits from the trachea to the right lung; it is wider, shorter, and more vertical.
What is the Right Bronchus
These span the space between ribs on the outside. They function to elevate the ribs
What are the External Intercostal Muscles
The front two-thirds of the roof of the mouth, behind the teeth and gums.
What is the hard palate
These are small, paired, pyramid-shaped cartilages located on the posterior aspect of the cricoid cartilage
What are Arytenoid Cartilages
Located at the bottom, below the oblique fissure.
What is the Right Lower Lobe
Tiny, branching airways (1 mm or less) that lack cartilage and lead from the bronchi into the alveoli.
What is the Bronchioles
Located just deep to the external layer. They work oppositely, pulling the ribs down to compress the thoracic cavity
What are the Internal Intercostal Muscles
These tonsils are the large, visible ones at the sides of the throat, commonly called "the tonsils,"
What are the Palatine tonsils
This is a U-shaped bone in the neck that anchors the tongue and muscles
What is the hyoid bone
The upper section, which includes the lingula (a structure analogous to the right middle lobe)
What is the Left Upper Lobe
The tube that splits from the trachea to the left lung; it is narrower and more horizontal.
What is the Left Bronchus
Lines the internal surface of the thoracic wall, diaphragm, and mediastinum. It is highly sensitive to pain.
What is the Parietal Pleura
These tonsils are smaller, bumpy tissues at the very base of the tongue
What are the lingual tonsils
This is a leaf-shaped flap of cartilage that covers the larynx (airway) during swallowing to prevent choking
What is the epiglottis
The lower section, separated from the upper by the oblique fissure.
Left Lower Lobe
Tiny, grape-like air sacs at the end of bronchioles where gas exchange (oxygen/carbon dioxide) occurs with blood.
What are the Alveoli
Located between the parietal and visceral layers. It contains a thin film of serous fluid that reduces friction during breathing
What is the Pleural Cavity
