Gland
|
structure that produces a chemical secretion necessary for normal body functioning.
|
|
|
Exocrine Gland
|
Gland that has a duct associated with it
|
|
|
Duct
|
Passageway that allows secretion to be emptied directly into the location where secretion is to be
|
|
|
Endocrine Gland
|
Ductless gland/ secretion poured directly into vascular system.
|
|
|
List the Glandular tissues in the head and neck
|
lacrimal, salivary, thyroid, parathyroid, thymus
|
|
|
Lacrimal Gland
|
Paired exocrine gland; secretes tears
|
|
|
Salivary Gland Functions
|
moistens mouth & food, makes speech possible, aids in digestion, neutralize acids, clumps bacteria
|
|
|
Glucoprotien in saliva function:
|
clump bacteria together for swallowing, wont cause systemic harm
|
|
|
Manor Salivary Glands
|
large paired, associated with ducts; parotid, submandibular, sublingual, minor salivary gland
|
|
|
Parotid Gland
|
Largest encapsulated gland, provides 25% of secretion, divides into superficial and deep lobes.
|
|
|
Parotid/Stensons Duct is associated with what gland?
|
Parotid Gland
|
|
|
Parotid Papilla
|
small elevation of tissue that marks opening to parotid duct on inner surface of cheeck opposite second molar.
|
|
|
Palpation of Parotid Gland
|
bilaterally palpated form anterior to each eat and move to cheek areas then to inferior to angle of mandible
|
|
|
Mumps
|
Enlargement of parotid gland, tender
|
|
|
Submandibular Salivary Gland
|
2nd largest encapsulated, provides 60-65% saliva
|
|
|
Submandibular/Wgartons duct
|
travels floor of the mouth and opens into sublingual caruncle
|
|
|
Palpation of submandibular Salivary Gland
|
bilaterally palpated by moving fingers inward form infeirior border of mondible near its angle as patient lowers head
|
|
|
Ranula
|
Submandibular gland lesion; salivary stone formation
|
|
|
Sialolith
|
Submandibular gland lesion; a hard calcified usually a symptomatic salivary stone
|
|
|
Sublingual Salivary Gland
|
Smalled most diffused and only unencapsulated salivary gland, 10% of saliva (includes small ducts along subling. fold)
|
|
|
Sublingual/Bartholins duct
|
formed by short ducts of gland that combine and opens into oral cavity through caurnicle
|
|
|
Sublingual Caurncle
|
small papillae near midline of floor of mouth on each side of lingual freneum.
|
|
|
Palpation os Sublingual Salivary Gland
|
Bilaterally palpate on flood of mouth posterior to mand. canine and 1 finger extraorally bw 2 fingers
|
|
|
Minor Salivary Glands
|
Smaller, numerous exocrine glands, scattered in tissues on B, L, and L mucosa, SP, lateral HP and floor of mouth
|
|
|
Von Ebners Glands
|
minor glands associated with large circumvallate lingual papillaw pon posterior region of dorsal surface of tongue
|
|
|
Mucocele
|
Minor Salivary Gland lesion, severence of duct from trauma thus blocking saliva flow
|
|
|
Thyroid Gland
|
Largest endocrine gland; produces & secreters thyroxine; 2 lat lobes, not visible, mobile when swallows, palpate soft mass
|
|
|
Isthmus
|
anteriorly connectes 2 loateral lobes of thyroid gland
|
|
|
Palpation of thyroid gland
|
locate thyroid cartilage and pass fingers to side and swallow
|
|
|
Goiter
|
Thyroid gland lesion, enlarged gland
|
|
|
Parathyroid Glands
|
4 small endocrine glands (paired), produce/secrete parathyroid hormone; regulates calcium & phosphorous; not visible or palpatable
|
|
|
Location of Parathyroid Glands
|
close to inside of posterior surface of thyroid gland
|
|
|
Thymus Gland
|
Endocrine gland; part of immune system; t-cells mature here; 2 lateral lobes, not palpable
|
|
|
Growth of Thymus
|
grows from birth to puberty, stops growing at puberty and begins to shrink, by 40 almost dissapeared (return to birth weight)
|
|
|
