Histology Flashcards
Tissue
Cells that are similar in structure and performs a specific function.
The 4 types of tissue
Epithelial, Connective, Muscle, Nervous
Epithelial sub-categories
both are categorized by number of layers - Simple and Stratified
And shape of the cell - squamous, cuboidal, columnar
also Transitional and glandular
Connective sub-categories
Connective tissue proper, Cartilage, Bone Tissue, Blood
Muscle Tissue sub-categories
Skeletal, Cardiac and Smooth
Nervous Tissue sub-categories
neurons, neuroglial cells
Simple squamous epithelial
secretes lubricating substances in serosae
Location - air sac of lungs, lining of the heart and blood vessels
Simple cuboidal epithelium
Secretion and absorption
Kidney Tubules
Simple columnar epithelium
secretion of mucus, enzymes, and other substances
Location - most of the digestive track
Pseudostratified columnar epithelium
secretes substances, particularly mucus
Location - male sperm carrying ducts,most of the upper respiratory track
Stratified squamous epithelial
Protects underlying tissues in areas subjected to abrasions
Location - mouth and vagina, also a dry membrane
Transitional epithelium
Stretches readily, permits stored urine to distend urinary organ
Location - lines the ureters, bladder,
Areolar loose connective tissue
wraps and cushions organs
Location - under epithelial of body
Adipose loose connective tissue
Provides reserve food fuel
Location - around kidneys and eyeballs
Reticular loose connective tissue
form a soft internal skeleton that supports other cell types
Location - Lymphoid organs
