Full Text. The hyoid bone is a horseshoe shaped bone found in the neck. Located anteriorly between the mandible and the thyroid cartilage, the hyoid bone protects the esophagus and also facilitates the wide range of muscle activity required for speaking and swallowing. It is visible upon extension of the neck.
The perichondrium as its name suggests surrounds cartilage. It is composed of a dense connective tissue. The innermost layer of that surrounding connective tissue has stem cells that can divide and provide a reservoir of cells that can secrete cartilage matrix. This is called the chondrogenic layer.he predominant fiber in the interterritorial matrix of cartilage is composed of elastin (the elastic fiber). Scan the 5x image noting the cartilage, its perichondrium and the elastic cartilage. Again, as in hyaline cartilage, the spaces are the lacunae each of which contains a chondrocyte.
