Tissues Flashcards
4 types of tissues
- epithelial tissue
- connective tissue
- muscle tissue
- nervous tissue
epithelial tissue
covers a surface or lines a hollow structure
squamous cell
flat/ scale-like cell
cuboidal
cube-shaped cell
columnar
column shaped cell
simple epithelial
one layer
function of epithelial tissue
secretion, absorption, filter
transitional epithelial
changes shape when stretched or relaxed
transitional epithelial arrangement
stratified
stratified arrangement
multiple layers
function of transitional epithelial
protection, distension
examples of transitional epithelial
lining of urinary bladder
Connective tissue
connects one type of tissue to another
connective tissue cells
living component of the tissue
matrix
non-living component of the tissue
gives tissue density
-“blast”
immature CT cell
-“cyte”
mature CT cell
fibroblast
immature CT cell that creates fibers
bone tissue
hyaline cartilage
fibro cartilage
elastic cartilage
blood tissue
plasma
ligaments and tendons
provides tensile strength
dense regular and irregular CT
dense irreglar CT
fibers run in different directions to make it more flexible and durable
adipose tissue
fat tissue
areolar CT
type of adipose CT
collagen fibers
elastic fibers
types of muscle tissue
skeletal muscle tissue
cardiac muscle tissue
smooth muscle tissue
skeletal muscle
muscles that connect to the bones
nervous tissue
neuroglia
neuroglia
modified epithelial cells
nervous system
brain
endocrine system
glands and hormones
receptor
detects a stimulus
control center
brain and spinal cord
effector organ
causes muscle tissue to contract
negative feedbck loop
response reverses original stimulus
positive feedback loop
response excellerates original stimulus
ATP
adenosine triphosphate
hypoxia
not enough oxygen at the tissue level
organs begin to shut down
homeostasis
maintaining equilibrium/ health
