The nares are also bounded laterally bywinglike cartilaginous structures, each ala (plural, alae) of the nose. In the orbital region of theface, the eyeball and all its supporting structures are contained in the orbit of the skull, thebony eye socket. On the midline of the upper lip extending downward from the nasal septumis a vertical groove, the philtrum.REF:Chapter 1, Nasal Region, Page 22.The lips are outlined from the surrounding skin by a transition area called the:a.philtrum.b.mucogingival junction.c.mucocutaneous junction.d.mandibular symphysis.ANS:CThe vermilion zone of each lip has a darker appearance than the surrounding skin, with thelips outlined from the surrounding skin by a transition zone, the mucocutaneous junction. Onthe midline of the upper lip extending downward from the nasal septum is a vertical groove,the philtrum. The line of demarcation between the firmer and pinker attached gingiva and themovable and redder alveolar mucosa is the scallop-shaped mucogingival junction. Themidline of the mandible is marked by the mandibular symphysis.REF:Chapter 1, Oral Region, Page 23.Which of the following structures can be palpated in the anterior midline of the neck?a.Thyroid cartilageb.Parathyroid glandsc.Sternocleidomastoid muscled.Submandibular salivary glandANS:AFound in the anterior midline and inferior to the hyoid bone is the thyroid cartilage, which isthe prominence of the “voice box,” or larynx. The vocal cords, or ligaments of the larynx, areattached to the posterior surface of the thyroid cartilage. The parathyroid glands are locatedclose to or within the posterior aspect of the thyroid gland but cannot be palpated in a patient;the thyroid gland can be palpated on a patient within the midline cervical area. The large strapmuscle, the sternocleidomastoid muscle, is easily palpated on each side of the neck. Thesubmandibular salivary gland is in the neck region but not in the midline.
