Four Primary Tissue Types

These flashcards encompass the key concepts and functions of the four primary tissue types, their components, and specific types of connective tissue as detailed in the lecture notes.

What are the four primary tissue types in the human body?

Connective, Epithelial, Muscle, Nervous.

What are the basic functions of connective tissue?

Connects anatomical structures, fills internal spaces, stores energy, provides support, and transports materials.

What is the main function of epithelial tissue?

Covers surfaces, lines cavities and tracts, and produces secretions from glands.

What does muscle tissue do?

Moves the body and organs.

What is the primary function of nervous tissue?

Conducts electrical impulses and carries information between the body and brain.

What are the three types of connective tissue?

CT proper, Supporting CT, and Fluid CT.

What components do all connective tissues contain?

Cells, protein fibers, and ground substance.

What are the components of connective tissue proper?

Cells, fibers, and ground substance.

Name a key characteristic of collagen fibers.

Collagen fibers are the most common and strongest protein fibers in connective tissue.

What is the primary role of fibroblasts in connective tissue proper?

Fibroblasts produce fibers and proteoglycans, and can differentiate into fibrocytes.

What are adipocytes and their function?

Adipocytes are fat cells that store lipids for energy.

What type of connective tissue is areolar connective tissue classified as?

Loose connective tissue.

What is the difference between loose CT and dense CT?

Loose CT has a loose framework, while dense CT consists of tightly packed cells and fibers.

What type of connective tissue provides padding and insulation for the body?

Adipose connective tissue.

What type of connective tissue is found in tendons and ligaments?

Dense regular connective tissue.
