Product Description

The function of laryngeal structure and function of amplifying model shows that the cartilage of the larynx and laryngeal continuous, laryngeal muscles and laryngeal cavity structure, cricoarytenoid joint motion and simulation as loud as a door or a glottal closure, the epiglottis cartilage activities cover the throat mouth.

Size: zoom in about 3 times, 30 x 15 x 14cm

Laryngeal cartilage
(for the laryngeal scaffold by thyroid cartilage and cricoid cartilage, epiglottis and paired arytenoid cartilage etc.)
1, thyroid cartilage
A: thyroid notch
B: upper corner
C: lower angle
2, annular cartilage
A: annular cartilage
B: annular cartilage plate
3, arytenoid cartilage
A: vocal fold
B: muscular process
4, small angle cartilage
5, epiglottis

Two, throat links (including links between laryngeal cartilage and larynx, trachea and hyoid link.)
6, ligamentum thyroepiglotticum
7, the ring joint
8, cricoarytenoid joint
9, elastic cone
10, median cricothyroid ligament (thyrocricoid thickening of the central part)
The larynx and hyoid and trachea connection:
11, the hyoid bone
A: the body of hyoid bone
B: thyrohyal
C: ceratohyal
12, annular cartilage trachea ligament
13, tracheal cartilage
14, the trachea ligament
15, tracheal membrane wall
16, trachea

Three, laryngeal muscles (muscles of larynx larynx and laryngeal muscle in muscle, laryngeal muscles and the larynx under movement and fixation, laryngeal muscles of vocal cord movement related, with tense or loose the vocal cords, loud door or glottal closure function.
17, thyrohyoid
18, posterior cricoarytenoid muscle
19, lateral cricoarytenoid muscle
20, the transverse arytenoid muscle
21, oblique arytenoid
22, the ring a muscle
23, thyroarytenoid muscle

Fourth, laryngeal cavity (surrounded by laryngeal cartilage, ligament, fibrous membrane, laryngeal muscles and mucous membrane of the larynx and the lumen, at the upper end of the self throat mouth and pharynx is communicated, and the lower end is connected in the trachea and lung, laryngeal cavity is vestibular folds and vocal fold into the vestibule of larynx and laryngeal intermediate cavities and infraglottic cavity.

24, vocal fold or vocal cords

Get rid of the thyroid cartilage located between the anterior horn and behind the vocal process of arytenoid cartilage folds of mucous membrane.

The vocal cords are composed of the vocal ligament, vocal cords, and the mucosa of the larynx.
