(31 cards)
Where can we find simple squamous epithelia?
urinary bladder and ureter
Where can we find stratified squamous?
nasal cavity, trachea, bronchii
Where can we find simple cuboidal?
skin, mouth, rectum
Where can we find stratified cuboidal?
pancreas, sweat glands, digestive glands
Where can we find simple columnar?
uterus, mammary ducts
Where can we find stratified columnar?
kidney tubules, salivary glands, sweat glands
Where can we find pseudostratified?
alveoli of lungs, capillary wall, and serous membranes
Where can we find transitional epithelium?
stomach, intestines
What is the apical surface?
surface facing the lumen/ external environment
What is the basal surface?
surface attached to basement membrane
Is epitheleal tissue vascular or avascular?
Avascular meaning they receive nerve supply from another source
Does epitheleal tissue have a high mitotic rate?
Yes, they are constantly regenerating since itis the part of the body that is exposed to injury
What are the types of supporting connective tissue
Cartilage and bone
What are the types of cartilage (CT)?
hyaline, elastic, fibro
What are some features of hyaline cartilage?
The most abundant, consists of chondrocytes (in lacunae), possible chondroblasts, and a matrix
What are some features of elastic cartilage?
Similar to hyaline cartilage but has elastic fibers in matric
What are some features of fibrocartilage?
It has chondrocytes and collagen fibers
What are the 3 broad categories of connective tissue proper?
Loose, dense, fluid
What are the categories within loose connective tissue?
Areolar and Adipose tissue
What is the difference between loose areolar CT and Adipose CT?
Areolar: has lots of space for fluid and fibers
Adipose: large fat vacuoles with nuclei on border
What are the categories within dense CT?
elastic
What is the difference between dense regular, irregular and elastic CT
Dense regular: collagen fibers are packed together with fibroblasts in between
Dense irregular: has collagen fibers but is not arranged
Elastic: stretchy
What is part of fluid ct?
blood and lymph
What makes up connective tissue?
ground substance, fibers, and cells
