Describe The Structure Of The Nasal Bone

1. Nasal bone
a. These bones serve as attachments sites for the cartilaginous tissues that shape the nose (AnatomyExpert, 2014).
2. Nasal Cartilage
a. The nasal cartilage articulates with the ethmoid bone to anteriorly separate the nasal passage into two halves (Starkey, Brown, & Ryan, 2011).
3. Zygoma
a. The zygoma is a sturture that fused to the maxilla and the temporal bones to form the prominent zygomatic arch beneath the eyes (Starkey, et al., 2011).
4. Maxilla
a. The main functions for the maxilla bone are housing the teeth, forming the roof of the oral cavity, forming the floor and lateral wall of the nasal cavity, containing the maxillary sinus, and contributing to the floor of the orbit (Starkey, et al., 2011).
5. Temporomandibular joint TMJ
a. The temporomandibular joint (TMJ) is

Thyroid cartilage
a. The thyroid cartilage is the most prominent structure, forming the Adam’s apple (Starkey, et al., 2011).
b. The cartilage is a strong but flexible tissue which houses the vocal folds, also known as the vocal cords (AnatomyExpert, 2014).
12. Cricoid cartilage
a. The cricoids cartilage lies inferior to the thyroid cartilage, forming a ring of cartilage that surrounds the trachea (Starkey, et al., 2011).
13. Tracheal cartilage
a. The tracheal cartilage is strong but flexible tissue that helps support the trachea while still allowing it to move and flex during breathing (AnatomyExpert, 2014).
b. The C-shaped cartilages are stacked one on top of the other and start under the cricoids cartilage, and then continue to the throat to the stomach (AnatomyExpert, 2014).
14. Temporalis muscle
a. The temporalis muscle originates on the temporal fossa, and inserts onto the cornoid process of the mandible (Starkey, et al., 2011).
b. Its main function is to aid in biting (Starkey, et al., 2011).
15. Masseter muscle
a. The masseter muscle originates on the zygomatic arch, and inserts onto the inferior and lateral portion of the ramus of the mandible (Starkey, et al.,
