Chapter 7 Flashcards
Gland
structure that produces a chemical secretion necessary for body functioning
Exocrine gland
associated duct
Endocrine gland
ductless, pours recreation directly into to vascular system. which then carries the recreation to the region in which it is to be used.
Lacrimal gland
Exocrine
- paired and almond shaped
- Secretes tears
- upper lateral portion of the orbit
- Duct: lacrimal duct
- Pathway of secretions- over the eye into the lacrimal sac, excess fluid goes to nasolacrimal gland
Salivary glands
produce saliva
Major:
parotid
Submandibular
Sublingual
Minor:
No Names
Scattered
Parotid
Large major salivary gland (25%)
Duct: Stenson
Fluid: Serous (contains enzymes)
Location:In the cheek, the duct is located by maxillary second molar
CC:
- Mumps: large and tender to the touch
May be pierced by IA injection
Ranula
stone in any major salivary gland
Submandibular gland
65% of saliva
Duct: Wharton
Fluid: Serous and mucous (made of carbs)
Location: below the mandible
CC:
Most commonly has salivary stones
Sublingual Gland
Smallest major (10%)
- not encapsulated
Fluid: mucous
Location: under the tongue, superior to the mylohyoid
CC: 2nd most common to have stones
Minor salivary glands
Numerous
Mucous fluid
- except von ebners which sit along the circumvallate papilla
Location; all ove rte oral cavity
CC: Mucocele- a small stone
Thyroid gland
largest endocrine gland
- below thyroid cartilage
Secretes thyroxin
- Regulates metabolism
CC: Goiter
Parathyroid gland
4 small endocrine glands
Location; one each side of the thyroid
Secretion: regulator hormone, parathyroid hormone
No CC
Thymus Gland
4 small endocrine glands
Location: behind the sternum
CC: T- lymphocytes mature
Grows from birth to puberty, then begins to shrink
