The arches form the pillars of the fauces. The anterior pillar is the palatoglossal arch formed of the palatoglossus muscle. The posterior pillar is the palatopharyngeal arch formed of the palatopharyngeus muscle. Between these two arches on the lateral walls of the oropharynx is the tonsillar fossa which is the location of the palatine tonsil. [3]
The palatopharyngeal arch (pharyngopalatine arch, posterior pillar of fauces) is larger and projects further toward the middle line than the palatoglossal arch; it runs downward, lateralward, and backward to the side of the pharynx, and is formed by the projection of the palatopharyngeal muscle, covered by mucous membrane.
Head Mirror with head band: to focus light into the cavity under inspection; mirror is concave and is used with a Chiron lamp to produce a parallel beam of light; doctor views through the hole (average diameter of mirror is 3 & 1/2" & that of hole is 1/4") Head mounted lights with head band: to focus light into the cavity under inspection ...
The glossopharyngeal nerve continues past the palatine tonsil and innervates the posterior 1/3 of the tongue to provide general and taste sensation. [6] This nerve is most likely to be damaged during a tonsillectomy, which leads to reduced or lost general sensation and taste sensation to the posterior third of the tongue. [7] [8]
The head rests on the top part of the vertebral column, with the skull joining at C1 (the first cervical vertebra known as the atlas). The skeletal section of the head and neck forms the top part of the axial skeleton and is made up of the skull, hyoid bone, auditory ossicles, and cervical spine. The skull can be further subdivided into:
The posterior fasciculus lies in contact with the mucous membrane, and joins with that of the opposite muscle in the middle line. The anterior fasciculus, the thicker, lies in the soft palate between the levator and tensor veli palatini muscles, and joins in the middle line the corresponding part of the opposite muscle.
The adenoids, also known as the pharyngeal tonsils, are lymphoid tissue structures located in the posterior wall of the nasopharynx. Waldeyer's tonsillar ring is an annular arrangement of lymphoid tissue in both the nasopharynx and oropharynx. The nasopharynx is lined by respiratory epithelium that is pseudostratified, columnar, and ciliated.
The retropharyngeal space (abbreviated as "RPS" [1] [2]) is a potential space [2] [3] and deep compartment of the head and neck [1] situated posterior to the pharynx. [4] The RPS is bounded anteriorly by the buccopharyngeal fascia, posteriorly by the alar fascia, and laterally by the carotid sheath.
