PH Week 1 - Epithelial Tissue Flashcards

Flashcards for MRAD 2235 Week 1 Lecture on Epithelial Tissue

What is Epithelial Tissue?

Tissue primarily responsible for protection and covering, absorption, and secretion.

What is Connective Tissue?

Tissue that provides structural support, packaging, and connection between other tissues.

What is Extracellular Matrix (ECM)?

The network of proteins and molecules outside of cells that provides structural and biochemical support to surrounding cells.

What is Histology?

The study of tissues and their structures.

What is Physiology?

The study of the functions and processes of the body's systems.

What is Basement Membrane?

A thin, sticky layer that connects epithelial tissue to underlying connective tissue.

What are Cell Junctions?

Structures that provide adhesion and communication between epithelial cells.

What are Tight Junctions?

Transmembrane proteins that create leak-proof sheets by binding cells together.

What are Gap Junctions?

Specialized connections that allow for communication between adjacent cells via open pores.

What are Anchoring Junctions?

Connections that stabilize cells and prevent them from being pulled apart.

What is Glandular Epithelium?

Discrete collections of epithelial cells that produce and secrete substances.

What is Hyaline Cartilage?

The most common type of cartilage, providing support and minimizing friction at joints.

What are Collagen Fibers?

The most abundant protein fibers in connective tissue, providing resilience and strength.

What are Fibroblasts?

The most abundant cell type in connective tissue that synthesizes and secretes ground substance and protein fibers.

What are Adipocytes?

Cells that store triglycerides and serve as an energy reservoir.

What are Proteoglycans?

Molecules in the ECM that provide structure and retain water.

What are Osteoblasts?

Bone cells responsible for forming new bone by synthesizing the extracellular matrix.

What are Chondrocytes?

Cells found in cartilage that maintain its ECM, providing support and flexibility.

What is Epithelial Membrane?

A structure consisting of an epithelial layer and an underlying connective tissue layer.

What are the Types of Connective Tissue?

Includes loose connective tissue, dense connective tissue, adipose tissue, cartilage, bone, and blood.

What is Tissue Repair?

The process by which injured tissue regenerates or heals, often involving stem cells.

What is Vascularization?

The presence of blood vessels within a tissue, indicating its ability to supply nutrients and remove waste.
