Tissues and Histology Review

A collection of vocabulary flashcards based on the key concepts from the lecture notes on tissues and histology to aid in exam preparation.

Histology

The study of tissues and cells under a microscope.

Histopathology

The diagnosis and study of diseases of the tissues, involving examination under a microscope.

Four basic tissue types

Epithelial tissue, connective tissue, muscle tissue, nervous tissue.

Epithelial Tissue

A type of tissue classified by cell shape: squamous, cuboidal, and columnar, with functions including protection, absorption, and secretion.

Squamous Epithelium

Epithelial cells that are wider than they are tall.

Cuboidal Epithelium

Epithelial cells whose height and width are approximately the same.

Columnar Epithelium

Epithelial cells that are taller than they are wide.

Stratified Squamous Epithelium

A type of epithelium with protective functions, typically found in the outer layer of skin.

Transitional Epithelium

Cells that change shape when stretched, found in the urinary tract.

Pseudostratified Columnar Epithelium

Epithelial tissue that appears to have multiple layers due to varying cell heights but is actually a single layer.

Cardiac Muscle

Involuntary, striated muscle found in the heart, responsible for pumping blood.

Skeletal Muscle

Voluntary, striated muscle attached to bones, enabling conscious movement.

Smooth Muscle

Involuntary, non-striated muscle found in internal organs, controlling functions like propulsion of substances.

Connective Tissue

Supports, binds, and connects other tissues and organs with various types, including bone and adipose.

Loose Connective Tissue

Connective tissue characterized by a loose arrangement of fibers, providing support and cushioning.

Adipose Tissue

Specialized connective tissue that stores fat and provides insulation and cushioning.

Dense Connective Tissue

Tissue that provides strength and support, including ligaments and tendons.

Supporting Connective Tissues

Tissues including bone and cartilage, providing structural support to the body.

Blood

Connective tissue that circulates throughout the body, transporting oxygen, carbon dioxide, and nutrients.

Red Blood Cells (Erythrocytes)

Blood cells responsible for transporting oxygen and carbon dioxide.

White Blood Cells

Cells that are part of the immune system, helping to fight infections.
