Glandular Epithelium - Page 1

Vocabulary flashcards covering key terms related to glandular epithelium, endocrine vs. exocrine glands, and related structures from Page 1 notes.

Gland

A structure that produces and secretes a chemical product.

Avascular

Lacking blood vessels between tightly packed cells in epithelial tissue.

Endocrine gland

Gland that releases its products directly into the bloodstream; hormones are produced here.

Exocrine gland

Gland that releases products into an exiting duct; not hormones.

Unicellular exocrine gland

An exocrine gland formed by a single cell (e.g., goblet cell).

Multicellular exocrine gland

An exocrine gland formed by more than one cell; can be structurally and functionally classified.

Keratinized stratified squamous epithelium

Stratified squamous epithelium that contains keratin, giving the epidermis its toughness.

Non-keratinized stratified squamous epithelium

Stratified squamous epithelium without keratin; found in wet areas (cheeks, esophagus, vaginal canal) and resists abrasion.

Stratified squamous epithelium

Epithelium with multiple cell layers; top layer is flattened (squamous) for protection.

Stratified cuboidal epithelium

Several layers with the top layer cuboidal; a rare epithelial type; found in excretory ducts of sweat glands.

Stratified columnar epithelium

Several layers with the top layer columnar; a rare epithelial type; found in the excretory ducts of salivary glands and in the male urethra.

Transitional epithelium

Epithelium that transitions from a relaxed to stretched state; lines the urinary bladder and ureter.

Urinary bladder

Organ whose wall is lined by transitional epithelium and that stretches as it fills with urine.

Ureter

Tube that transports urine from the kidney to the urinary bladder and is lined by transitional epithelium.

Goblet cell

Unicellular exocrine gland that secretes mucus.

Mucus

Secreted mucus produced by goblet cells and other glands.

Sweat glands

Exocrine glands that secrete sweat through ducts.

Ceruminous glands

Exocrine glands that produce earwax (cerumen) in the ear canal.

Salivary glands

Exocrine glands that secrete saliva into ducts.

Pancreas (endocrine secretions)

Endocrine secretions: insulin and glucagon.

Pancreas (exocrine secretions)

Exocrine secretions: pancreatic enzymes.

Hormones

Chemical products released directly into the bloodstream by endocrine glands.

Major endocrine glands (PTSP)

Parathyroid, Thyroid, Suprarenal (adrenal), and Pituitary glands.
