animal tissues Flashcards
simple squamous epithelial tissue location
-lining of blood vessels (endothelium)
-lining of alveoli/inner surface of alveoli
-lining of visceral organs
-forms diffusion boundary
cuboidal epithelium location
-pct
-ducts of glands
-tubular parts of nephron
-ependyma; ovary and testes
columnar epithelium nuclei
basal nuclei
pseudostratified epithelium
trachea and bronchi
columnar epithelium location
-glandular epithelium for glands (also a type of cuboidal)
-lining of stomach and intestine(brush bordered)
-pct
-bronchioles and fallopian tube(cilliated)
exocrine glands secretion
saliva;earwax;mucus;gastric juices;intestinal juices
main function of compound epithelium
protects against chemical and mechanical abrasions
location of compound epithelium
dry surface of skin
moist surface of buccal cavity
pharynx
innner lining of ducts of sal glands and pancreatic glands
types of cell junctions
tight
adhering
gap
tight junction
stop substances from leaking across a cell
adhering junctions
provide cementing between 2 cells
gap junctions
connect the cytoplasm of 2 adjacent cells through plasmodesmata
most abundant tissue and widely distributed
connective
specialised ct include
-cartilage
- bone
- blood
- adipose
ct cells secrete
fires of structural proteins
- collagen - elastin
also secrete modified polysaccharides
ct divided into 3 types
- dense
-loose
-specialised
areolar consists of
fibroblasts
mast cells
macrophages
types of loose ct
areolar and adipose
dense ct types
regular and irregular
ex. ligaments and tendons. ex. in the skin
bone to muscle
tendon
