Key Anatomical Areas Covered:

1. Nasal Cavity

The model illustrates the internal structure of the nasal cavity, including:

• Nasal Septum

• Superior, Middle, and Inferior Nasal Conchae

• Nasal Vestibule

• Nasal Bone

• Lower Nasal Cartilage

• Ethmoid and Sphenoid Sinuses

These features help students understand nasal airflow, olfactory function, and sinus drainage pathways.

2. Oral Cavity

Important components of the mouth are clearly shown, such as:

• Upper and Lower Lips

• Hard and Soft Palates

• Tongue

• Uvula

• Floor of the Mouth

These elements are crucial in phonation, mastication, and the initial phases of swallowing.

3. Pharynx

This region includes:

• Nasopharynx

• Oropharynx

• Laryngopharynx

• Palatine and Lingual Tonsils

• Pharyngeal Arches and Wall

The pharyngeal area is vital in coordinating both respiratory and digestive pathways.

4. Esophagus

The esophageal structure is depicted with clear anatomical accuracy, facilitating the understanding of food propulsion from the pharynx to the stomach.

5. Larynx

The model provides a detailed view of:

• Epiglottis

• Thyroid and Cricoid Cartilages

• Vocal Cords

• Laryngeal Cavity

• Vestibular and Vocal Ligaments

This is essential for studying speech production and airway protection during swallowing.

Musculature Involved in Swallowing

The PX-C639 model showcases over 20 muscles related to swallowing function, including:

• Orbicularis Oris

• Buccinator

• Pharyngeal Constrictors

• Suprahyoid and Infrahyoid Muscles

• Tongue Muscles (Intrinsic and Extrinsic)

• Thyrohyoid, Sternothyroid, and Omohyoid Muscles

This comprehensive view enables learners to understand the sequential muscular actions required during each phase of the swallowing process.
