Tissues Flashcards
A group of cells that coordinate to carry out a specialized function
Tissues. The cells within a tissue are usually of common embryonic origin.
What is Histology?
Study of tissues
A scientist that examine tissue and cells to determine if a disease is present
pathologist
Tissue that covers all body surfaces, lines body cavities, hollow organs, and tubes, forms glands
Epithelial tissues
Tissues that protects/supports the body and organs, binds organs together, serves as a fat reserve and provides immunity
Connective tissues
What tissues generates movement and heat?
Muscular tissue
Tissue that responds to environmental stimuli and coordinates body homeostasis
Nervous tissue
Name the four types of tissues
Epithelial tissues
Connective tissues
Muscular tissue
Nervous tissue
Where are cell junctions found?
Cell junctions can be found in epithelial, muscle, and nerve cells
Two common characteristics of cell junctions
- They all allow the neighboring cells to communicate with each other more effectively
- They hold neighboring cells together
What tissue type covers all body surfaces, lines body cavities, hollow organs and tubes, forms glands?
Epithelial Tissue
What tissue type protects/supports the body and organs, binds organs together, serves as a fat reserve and provides immunity?
Connective Tissue
What tissue type generates movement and heat?
Muscular Tissue
What tissue type responds to environmental stimuli and coordinates body homeostasis?
Nervous Tissue
What tissue type is closely packed together, arranged in continuous sheets, avascular, has a nerve supply, regenerates quickly, and contains an apical surface and basal surface?
Epithelial Tissue
Term describing a thin layer between epithelial tissue and connective tissue
basement membrane
Epithelial tissue contains an apical surface and basal surface. What do apical surface and basal surface describe?
Apical side faces the body cavity.
Basal surface is attached to a basement membrane.
What are the characteristics of a simple layer in epithelial tissue?
Single layer of cells. Diffusion, secretion and absorption
What are the characteristics of a stratified layer in epithelial tissue?
2 or more layers. Protection, with basement membrane
What are the characteristics of a pseudostratified layer in epithelial tissue?
Contains multiple and single layers. May secrete mucous or contain cilia
What are the characteristics of a squamous shape in epithelial tissue?
Thin. Rapid passage of substances.
What are the characteristics of a cuboidal shape in epithelial tissue?
Cubed/hexagon shaped. Secretion and absorption
What are the characteristics of columnar cell shape in epithelial tissue?
More tall than wide (column shaped). Protection, secretion and absorption
What are the characteristics of transitional cell shape in epithelial tissue?
Cells change shape as they are subjected to bodily movement.
What is the function of Simple Squamous Epithelium?
Filtrations, diffusion, osmosis
What is the function of Simple Cuboidal Epithelium?
Secretion and absorption.
What is the function of Stratified Columnar Epithelium?
Secretion and protection
Do endocrine glands secrete into ducts?
No ducts and secrete directly into the surrounding extracellular fluid. Ex: Adrenal glands, Thyroid glands, Pituitary glands
Do exocrine glands secrete into ducts?
Yes, salivary glands and
sweat glands.
What type of tissue holds organs in place, supports and strengthens other tissue, protects organs, insulates organs, serves as a transport system, stores energy, and is the main site of immune response?
Connective tissue
In connective tissue, what is the material between the cells and is composed of protein fibers and ground substance?
extracellular matrix
