Week 3 - Exam 1 Flashcards
epithelial cells function
covering/bordering body/organ, protects from environment, connected to underlying tissue via basal membrane
4 types of epithelial cells
squamous, stratified, transitional, and glandular
where can you find simple squamous epithelial cells and why
lung, kidney, glands; 1 layer allows for easier diffusion
where can you find stratified epithelial cells
skin and rumen (stomach of cow)
where can you find transitional epithelial cells
urogenital tract (only)
structure of a glandular epithelial cell
duct, cells, secretory units, basement membrane
types of structures of exocrine glandular epithelial cells
tubular, branched, coiled, alveolar
3 major classes of glandular epithelial cells
exocrine, endocrine, and paracrine
3 types of exocrine glandular epithelial cells
merocrione, apocrine, holocrine
function of a glandular epithelial cells
produce secretions (proteins=enzymes, lipids, carbs)
3 characteristics of a fiber
collagen, glycosaminoglycans, hyaluronic acid
function of adipose tissue
energy storage, temperature insulation
where can you find supportive tissue
cartilage, bone
3 types of cartilage
elastic, hyaline, fibrous
where can you find elastic cartilage and function
ear, larynx, trachea; provide structural support
where can you find hyaline cartilage and function
joint surface; provides joint movement, cushions movement, no blood vessels
where can you find fibrous cartilage
intervertebral discs, meniscus in knee and jaw
merocrione function
fuses, then dumps contents (like the bubbles we saw with Golgi Apparatus)
apocrine function
don’t dump contents
holocrine function
cell wall ruptures, dies, but high turn over rate (found in digestive tract)
endocrine function & example
product goes inside (example: adrenal gland: hormones into blood)
paracrine function
release components and influence cell itself again
collagen arches
help with springiness
no vascular supply usually means
poor healing quality
