Tissues and Histology

These flashcards cover key terms and definitions related to tissues and histology as outlined in the lecture notes.

Histology

The microscopic study of tissues.

Biopsy

Removal of tissues for diagnostic purposes.

Autopsy

Examination of organs of a dead body to determine cause of death.

Epithelial Tissue

Tissue type that covers body surfaces and forms glands.

Extracellular Matrix

Noncellular substance that separates cells in connective tissue.

Tight Junctions

Endocrine Glands

Glands that produce hormones and have no open contact with the exterior.

Exocrine Glands

Glands that maintain open contact with the exterior through ducts.

Merocrine Secretion

Leukocytes

White blood cells that respond to injury or infection.

Dendrites

Cell processes that receive impulses from other neurons.

Smooth Muscle

Involuntary muscle associated with tubular structures and skin.

Nervous Tissue

Tissue composed of neurons that produce electrical signals.

Cutaneous Membrane

Composed of epithelial tissue and underlying connective tissue; commonly known as skin.

Collagen
