Histology- Epithelial Tissue Flashcards

Study Notes

Connective tissue is characterized by the presence of highlighted fibers, indicating its structure and support functions.
The basement membrane is a specialized layer that underlies epithelial tissues, providing support and anchorage.
Fibroblasts are the cells responsible for producing fibers within connective tissue, playing a critical role in tissue repair and maintenance.

Cilia are hair-like structures on the epithelial cell surface that aid in movement and sensory functions.
Goblet cells are specialized epithelial cells that secrete mucin, contributing to mucus production and lubrication.
Neurogliacells support neurons in the nervous system, maintaining homeostasis and insulating neuronal axons.

Endothelium refers specifically to the simple squamous epithelium lining blood vessels, crucial for vascular health and function.
Pseudostratified columnar epithelium features cells of varying heights, providing protection and secretion, typically found in the respiratory tract.
Simple columnar epithelium is composed of a single layer of tall cells, often involved in absorption and secretion in digestive organs.
Simple cuboidal epithelium consists of cube-shaped cells, often found in glands and kidney tubules, facilitating secretion and absorption.
Simple squamous epithelium consists of flattened cells, allowing for efficient diffusion and filtration in areas such as alveoli in the lungs.
Stratified squamous epithelium provides protection against abrasion and is found in areas like the skin and oral cavity.

Striation is a defining feature of skeletal and cardiac muscle tissue, indicating organized myofibrils necessary for contraction.
Cardiac muscle fibers are specialized for automatic and rhythmic contractions found in the heart.
Skeletal muscle fibers are long, cylindrical, and voluntarily controlled, enabling movement and support.

Dense regular connective tissue is characterized by closely packed collagen fibers, providing tensile strength found in tendons and ligaments.
Elastic cartilage contains elastic fibers, granting flexibility and support in structures such as the ear and epiglottis.
