Tissue Level of Organisation

These flashcards cover key terms and concepts related to the four major tissue types in the human body, their characteristics, structures, and functions.

Epithelial Tissue

Tissue that covers all internal and external surfaces of the body, providing protection and enabling sensation.

Connective Tissue

Tissue that supports, surrounds, and interconnects other types of tissue, playing roles in structural framework, nutrient transport, and defense.

Muscle Tissue

Tissue composed of cells that can contract to facilitate movement within the body.

Nervous Tissue

Tissue that transmits electrical signals throughout the body, consisting mainly of neurons and neuroglia.

Stem Cells

Undifferentiated cells capable of giving rise to various types of specialized cells; includes adult stem cells (partially differentiated) and embryonic stem cells (pluripotent).

Simple Squamous Epithelium

A single layer of flattened cells allowing diffusion and filtration, found in areas like the lungs and blood vessels.

Stratified Squamous Epithelium

Multiple layers of flat cells designed to protect against mechanical stress; found in the skin and mucous membranes.

Cuboidal Epithelium

A type of epithelium consisting of cube-shaped cells, allowing secretion and absorption, commonly found in kidney tubules.

Columnar Epithelium

Tall, column-like epithelial cells that are specialized for absorption and secretion, often found in the digestive tract.

Connective Tissue Fibers

Components of connective tissue including collagen, reticular, and elastic fibers that provide structure and support to tissues.

Glandular Epithelium

Specialized epithelial cells that form glands for secretion, can be unicellular or multicellular, and classified based on their secretory methods.
