anatomy clinical neck Flashcards
where can infections between the investing/infrahyoid fascia and pre tracheal fascia spread inferiorly into
superior mediastinum
where can infections deep to the pre vertebral layer extend laterally, protruding into
along the posterior border of the SCM
where can infections between the buccopharyngeal fascia and alar fascia spread inferiorly into
lower cervical layers
what refers to an infection between the cervical vertebrae and the pharyngeal wall
retropharyngeal abscess
where do infections reach the retropharyngeal space from
oral cavity (dental abscess) and nasopharynx (tonsillitis, peritonsillar abscess)
what are signs and symptoms of retropharyngeal abscess
fever, sore throat, dysphagia, odynophagia, neck and back pain
what are some complications of retropharyngeal abscesses
airway obstruction, sepsis, mediastinhtis, pneumonia, empyema, jugular vein thrombosis, carotid artery erosion
what does spasmodic torticollis result from
disease in the basal nuclei
what will anesthesia injected along the posterior border of the mid-SCM affect (nerves)
great auricular, lesser occipital, transverse cervical, and supraclaviculars
what must be avoided with a subclavian vein puncture
first rib, phrenic nerve, subclavian artery, cupola of the lung
where can the right IJV be punctured
just lateral to the common carotid in the interval between the sternal and clavicular heads of the SCM
where is nerve block to the cervical plexus administered
along the posterior edge of the middle 1/3 of the SCM
where is the nerve block for the brachial plexus administered
injected above the clavicle (erb’s point)
what does nerve block to stellate ganglion impact
sympathetic function
where can the carotid pulse be palpated
between the trachea and the anterior border of the SCM
what does hypersensitivity of the carotid sinus result in
episodes of diminished cerebral blood flow and fainting spells
what has lesions with horner’s syndrome
cervical sympathetic trunk
what nerve is spared with horner’s syndrome without anhydrosis or flushing
external carotid nerve
what percentage of people have a thyroid ima artery
10
what nerve is endangered when there is ligation of the superior thyroid artery
external laryngeal nerve
what nerve is in endanger with ligation of the inferior thyroid artery
recurrent laryngeal nerve
what is the lymphatic drainage of the isthmus of the thyroid gland
prelaryngeal/tracheal to the paratracheal to the deep cervical
where does lymph from the lateral lobes of the thyroid gland drain
directly to superior and inferior deep cervical nodes
