Q

Know the digestive and respiratory pathways through the head and neck. –Where do these pathways cross?

A

OROPHARYNX- post edge of oral cavity and middle of pharynx cavity

Q

•Layer 1: Endocrine layer– location and blood supply of the thyroid and parathyroid glands•

A

Thyroid- ductless hormone secreting
Location- largest endocrine. Lies over trachea
Isthmus over 2-3rd rings connects two lobes, may have . pyramidal lobe
Blood supply- superior thyroid a.-ECA, inferior thyroid a.-thyrocervical trunk, thyroid ima a. (10%) branch of brachioceplahlic or aorta arch
Thyroid vein drain into IJV
Superior and middle
Inferior thyroid v. drains to brachioceplahic v.

Innervation- regulated by pituitary gland (hypopheasal fossa) NO GVE!!!
Parathyroid- tiny gland posterior to thyroid

Q

Layer 2: Respiratory layer- Larynx and Trachea

A

Larynx fx- 1-adducts vocal cords to provide air and increase intrathoracic pressure 2- route of air and food into appropirate passage ways (lungs and digestive)
3. voice production
