Cervical Viscera Flashcards
Where is the Thyroid Gland
deep to infrahyoid muscles, in area of C5-T1
Function of Thyroid
Endocrine Function: role in metbaolism growth temperature regulation sympathetic activity secretes T3&T4 secretes calcitonin
Where are Parathyroid Glands Located
on each lobe of the thyroid
What is the Function of the Parathyroid
maintaining calcium and phosphate balance
Two functions of the Pharynx
pass food to esophagus & conduct air to larynx and trachea
Nasopharynx
superior to soft palate and posterior to nasal cavity
Oropharynx
soft palate to tip of epiglottis
Laryngopharynx
epiglottis to cricoid cartilage
Functions of Larynx
connects pharynx to trachea
voice production
Innervation of the Larynx
Vagus Nerve (CN10) superior laryngeal nerve (internal/external) recurrent laryngeal nerve (becomes inferior laryngeal)
trachea
goes from inferior larynx to sternal angle
Esophagus
muscular tube, posterior to trachea
descends through superior/posterior mediastinum
pierces diaphragm and enters stomach
Musculature of esophagus
voluntary (striated) in first 1/3, involuntary (smooth) in lowest 1/3, combination in middle
