Chapter1. Anatomy and Physiology of the Larynx. 1.1 Anatomy. 1.1.1 Laryngeal Cartilages. 1.1.1.1 Thyroid. The laryngeal skeleton consists of several cartilaginous struc-tures (Fig. 1.1), the largest of which is the thyroid cartilage. The thyroid cartilage is composed of two rectangular laminae that are fused anteriorly in the midline.
1 Ιαν 2010 · It emphasizes the structure of the laryngeal framework, the innervation and blood supply of the larynx and trachea, the anatomic differences between the pediatric and adult larynx and...
Gross anatomy We now shift away from histologic anatomy to focus on the macroscopic or gross anatomic features of the larynx. Vocal fold shape and movement are primarily the result of intrinsic laryngeal muscle activity (Fig. 3). To a lesser degree, extrinsic laryngeal muscles also affect vocal fold shape and movement.
30 Οκτ 2023 · This article will discuss the major anatomical structures and the main functions of the larynx. It will also outline the blood supply, innervation and lymphatic drainage of the larynx as well as a clinical application and an interesting fact.
Anatomy. The larynx is located at the point where the respiratory and digestive tracts separate. The entrance to the larynx, or laryngeal inlet, is in the anterior wall of the laryngopharynx. Internally, the wall of the larynx is modified to form the vocal cords.
SKELETAL STRUCTURE. Framework: 11 cartilages linked by joints and fibroelastic structures. 3 odd-and median cartilages: the thyroid, cricoid and epiglottis cartilages. 4 pair cartilages: corniculate cartilages of Santorini, the cuneiform cartilages of Wrisberg, the posterior sesamoid cartilages and arytenoid cartilages.
Describe the important anatomical features and innervation of the external, middle, and inner ear. Describe the sensory innervation of the nasal cavity, and the sensory and motor innervation of the glossopharyngeal and vagus nerves related to the pharynx and larynx.
