The isthmus of the thyroid would be encountered during a tracheostomy procedure. ","question3":"The internal carotid artery can be palpated against the anterior tubercle of the transverse process of C6.","answers3":"True | False","correctAnswerText3":"At this level, the common carotid would be palpated. It bifurcates usually, around the C4 level although this is variable between individuals.","correctAnswer3":"1","question4":"The posterior border of the sternocleidomastoid forms the posterior border of the anterior triangle.","answers4":"True | False","correctAnswer4":"1","correctAnswerText4":"The anterior triagle is situated at the front of the neck it is bounded superiorly by the inferior border of the mandible, laterally by the anterior border of the sternocleidomastoid and medially by the sagittal line done the midline of the neck. ","question5":"The submandibular triangle contains most of the parotid gland.","answers5":"True | False","correctAnswer5":"1","correctAnswerText5":"The submandibular triangle is located underneath the body of the mandible it contains the submandibular gland and lymph nodes ","question6":"The digastric and omohyoid muscles are both important in the boundaries of the subtriangles of the anterior triangle of the neck.","answers6":"True | False","correctAnswer6":"0","correctAnswerText6":"The anterior triangle is subdivided by the hyoid bone, suprahyoid i.e. diagastric and infrahyoid muscles i.e. Omohyoid into four triangles.","question7":"The accessory nerve is an important nerve to be aware of when performing a procedure in the posterior triangle of the neck.","answers7":"True | False","correctAnswer7":"0","correctAnswerText7":"Outside the cranium, the spinal part of the accessory nerve descends along the internal carotid artery to reach the sternocleidomastoid muscle, which it innervates. It then moves across the posterior triangle of the neck to supply motor fibres to the trapezius.","question8":"A fluctuant mass found in the posterior triangle of the neck is likely to be a pharyngeal pouch.","answers8":"True | False","correctAnswer8":"1","correctAnswerText8":"A Pharyngeal pouch is a herniation of the pharyngeal mucosa and submucosa through the weakness in the inferior constrictor muscles of the pharynx. More common in older men. Usually not seen, but if large then a midline lump in the neck that gurgles on palpation.","question9":"A thorough examination of the ear nose and throat is important on discovery of cervical lymphadenopathy.","answers9":"True | False","correctAnswer9":"0","correctAnswerText9":"Malignancies of the head and neck structures frequently metastasise to the cervical lymph nodes. Malignancy from other regions for example the breast, gastro intestinal tract and the lung may also metastasise to the cervical lymph nodes and these areas should be examined where appropriate.","question10":"A mass in the submandibular region can only be determined as nodal or arising from the submandibular gland by imaging.","answers10":"True | False","correctAnswer10":"1","correctAnswerText10":"A mass arising from the submandibular gland will be palpable bimanually with a finger on the floor of the mouth and the thumb under the angle of the jaw. A nodal mass will be apparent below the angle of the jaw only.
