Tissues
What is Histology
Study of Tissues
What are the two main classifications of epithelial tissue?
Simple and stratified.
What is connective tissue responsible for?
Binding and supporting other tissues.
Where is skeletal muscle tissue found?
In muscles that attach to bones or skin.
How does collagen contribute to connective tissue?
It provides strength and support.
4 main types of tissue
Epithelial, Connective, Muscle and nervous
What shapes can epithelial cells have?
Squamous, cuboidal, and columnar.
What type of tissue is blood classified as?
Connective tissue.
Where is elastic cartilage found?
In the external ear (pinna) and the epiglottis.
What is mesenchyme, and why is it important?
Mesenchyme is embryonic connective tissue that forms all other connective tissues.
Process for viewing tissue under a microscope
Tissue must be fixed, sectioned, and stained.
What is the primary function of simple squamous epithelium?
Diffusion and filtration.
What fibers are found in connective tissue?
Collagen, elastic, and reticular fibers.
Where is hyaline cartilage found?
In the costal cartilage, embryonic skeleton, and end of long bones.
What is the role of ground substance in connective tissue?
It helps nutrients diffuse between blood and cells.
What is the function of bone tissue?
It supports, protects, provides levers for movement, and stores calcium and fat.
What is the role of goblet cells in epithelial tissue?
Goblet cells secrete mucus.
What is the function of dense regular connective tissue?
It attaches muscles to bones, and bones to bones.
Where is dense regular connective tissue found?
In tendons, ligaments, and aponeuroses.
What are the characteristics of dense regular connective tissue?
It has parallel collagen fibers with few elastic fibers and major fibroblast cells.
What is the difference between light and electron microscopy?
Light microscopy uses dyes, while electron microscopy uses heavy metals.
Where is transitional epithelium located?
In the urinary bladder, ureters, and urethra.
What is hyaline cartilage known for?
It has a firm matrix with an imperceptible network of collagen fibers and provides support and cushioning
Where is reticular connective tissue found?
In lymph nodes, bone marrow, and the spleen.
What is the role of blood in connective tissue?
Blood transports respiratory gases, nutrients, and wastes.
