Chpt. 7 Glandular Tissue Flashcards
Type of gland without a duct, with the secretion being poured directly into the vascular system, which then carries the secretion to the region in which it is to be used.
Endocrine gland
Type of gland with an associated duct that serves as a passageway for the secretion so that it can be emptied directly onto the location where the secretion is to be used.
Exocrine gland
In the head and neck area, it includes the lacrimal, salivary, thyroid, parathyroid, and thymus.
Glandular tissue
Structure that produces a chemical secretion necessary for normal body functioning.
Gland
Enlarged thyroid gland due to a disease process.
Goiter
Reduced saliva production by salivary glands.
Hyposalivation
Contagious viral infection that usually involves both parotid salivary glands.
Mumps
Formation of stone within a salivary gland.
Salivary stone
Dry mouth.
Xerostomia
Location of lacrimal gland
Lacrimal fossa of frontal bone
Location of parotid gland
Parotid space posterior to the mandibular ramus, anterior and inferior to the ear
Location of the submandibular gland
Submandibular space: inferior and posterior to the body of the mandible
Location of the sublingual gland
Sublingual space: floor mouth, medial to the body of the mandible
Location Minor salivary glands
Buccal, labial, and lingual mucosa; soft and hard palate; floor of mouth; and base of circumvallate lingual papillae
Location of the thyroid gland
Inferior to hyoid bone, junction of larynx and trachea
Location of parathyroid glands
Close to or within thyroid
Location of thymus gland
In thorax, inferior to hyoid bone, superficial and lateral to trachea, and deep to sternum
Innervation of lacrimal gland
Greater petrosal of 7th cranial nerve and lacrimal nerves
Innervation of the thymus gland
Branches from 10th cranial nerve
Innervation of the parathyroid

Innervation of sublingual salivary gland
Chorda tympani nerve of 7th cranial nerve
Innervation of submandibular salivary gland
Chorda tympani of 7th cranial nerve
Innervation of parotid gland
Lesser petrosal of 9th nerve and auriculotemporal branch of 5th cranial nerve
