Tissue Basics
The microscopic study of tissues is known as this branch of biology.
What is Histology?
This term describes cells that are flat and scale-like in appearance.
What is Squamous?
This tissue type consists of a single layer of flat, scale-like cells with a centrally located nucleus.
What is Simple Squamous epithelium?
In stratified squamous epithelium, these underlying layers constantly divide and push older cells toward the surface.
What are the Basal layers?
Epithelial tissue that gives rise to the secreting portions of structures is called this.
What is Glandular epithelium?
This refers to a group of cells with a common origin performing a similar function.
What is a Tissue?
An epithelial tissue consisting of a single layer of cells is classified as this.
What is Simple?
Simple squamous epithelium that specifically lines the heart, blood vessels, lymph vessels, and capillary walls is called this.
What is Endothelium?
This tough, friction-resistant, waterproof protein protects stratified squamous tissue as surface cells dehydrate and harden.
What is Keratin?
A group of highly specialized epithelial cells that secrete substances into ducts, onto a surface, or into the bloodstream is defined as this.
What is a Gland?
This general tissue type is characteristically avascular, composed of tightly packed cells, and rests on a basement membrane.
What is Epithelial tissue?
These cells are characteristically taller than they are wide, appearing rectangular in cross-section.
What is Columnar?
This specific simple squamous lining covers the serous membranes of the thoracic and abdominopelvic cavities.
What is Mesothelium?
These hair-like projections on cell surfaces move substances along in a coordinated motion.
What are Cilia?
These specialized epithelial cells secrete mucus to serve as a lubricant or protective fluid layer.
What are Goblet cells?
These three specific terms describe how epithelial cell layers are arranged top-to-bottom.
What are simple, stratified, and pseudostratified?
This type of tissue contains only one layer of cells, but appears to have multiple layers due to nuclei positioned at varying depths.
What is Pseudostratified?
This tissue is formed by closely fitted cube-like cells with centrally located nuclei.
What is Simple Cuboidal epithelium?
Specialized structures on epithelial cells that increase surface area to aid in absorption are known as these.
What are Microvilli?
These ductless glands secrete their chemical products, called hormones, directly into the blood.
What are Endocrine glands?
This structural component of tissue consists of tightly packed cells surrounding the cellular structure.
What is the Matrix?
Epithelial tissue containing a combination of shapes that can stretch and change to prevent organ rupture is known as this.
What is Transitional epithelium?
Simple columnar epithelial cells typically feature their nuclei in this specific part of the cell structure.
What is at the base of the cell?
These rare stratified tissue types function primarily in protection and secretion.
What are Stratified Cuboidal and Stratified Columnar epithelium?
Glands that secrete their products into ducts or tubes that empty onto an epithelial surface are classified as this type.
What are Exocrine glands?
