Functions of tissue
function of all stratified tisses
ALL FUNCTION ARE PROTECTION
Endocrine
DUCTLESS. glandular tissue, classified by where product is secreted.
function of epilthelial tissue
Protection, Absorption, Filtration, Excretion Secretion, diffusion
function of basement membrane
acts as a 2 way filter-absorbs oxygen and nutrients
dense irregular connective tissue
all different directions, found in skin.
cutaneous
another name for your skin; exposed to air, and is considered a dry membrane
GLIA CELLS consist of:
astrocytes-anchor neurons to blood supply microglia-macrophages oligodendrocytes and schwann cells- produce myelin sheath of axons.
tissues with no regeneration capacity
cardiac muscle and nervous tissue
Axons
carry things AWAY from body
Dendrites
carry things away from the body.
neurons
cells that transfer stimuli to other cells. have axons and dendrites. ONLY one that can transmitt information
dense regular connective tissue
collagen fibers in single direction, made by fibroblasts or fibrocytes. found in tendons and ligaments.
types of connective tissue fibers
collagen, elastic, reticular.
classes of connective tissue
connective tissue proper, cartilage, bone and blood.
tissues with Good regeneration capacity
epithelial, bone, areolar, connective, dense irregular connective and blood
elastic cartilage
external ear, auditory canal. has collagen. has elastic fibers.
Peripheral blood
fibers: when clotting ground substance: blood plasma
cells inside connective tissues
fibroblasts and fibrocytes, chondroblasts and condrocytes, osteoblasts and osteocytes.
functions of peripheral blood
gas exchange, protection from pathogenic agents, control body temp, provides acid-base balance with buffers. transports nutrients. maintains osmotic balance.
exocrine
glandular tissue thats classified where product is secreted, which IS INTO a duct.
ground substance
holds large amounts of fluid; medium for transport of nutrients and other dissolved substances
cardiac muscle function and characteristics
involuntary, rythmic contraction. located in the heart. UNI NUCLEATED. branch, and stirated
function of pseudostratified epithelium
it has microvili and sterocilia which both increase absorption and increased surface area. increases absorption.
mucous membranes
line cavities that face outside the body. called wet membranes. epithelial connective and smooth muscle layer
serous membranes
line the closed body cavities. simple squamous and loose connective tissue.
Mesenchyme
mesoderm- CONNECTIVE TISSUE ONLY COMES FROM MESENCHYME
hyaline cartilage
most common. found in arms and legs- then made into bone. at the end of each bone is hyaline cartilage which allows you to grow. protective cartilage.nasal septem too.
endocrine system
nervous tissue works with it. nervous tissue makes eletrical msg, endocrine system makes chemical msh.
inflammatory response
non-specific response that develops quickly
apocrine secretion
product accumulates just beneath the surface of the cell, product pinches off containing secretion and some of the cytoplasm
function of squamous cells
promotes diffusion, gas exchange, filtration, secrete and makes things. MAINLY FOR DIFFUSION
function of simple squamous epithelial
promotes diffusion. (gasses, nutrients like AA or glucose).
function of transitional epithelium
protection, and allows you to expand and stretch.
fibrocartilage
resists stress, interveterbral discs- inbetween each vertebra
functions of bone
rigid support, attachement site for muscles, protection of organs, hemopoiesis, reserves for calcium and phosphorus
function of simple columnar epithelial
secrete and absorb products, and can produce enzymes for digestion.
function of simple cuboidal epithelial
secrete or absorb product that is in the tube. function in kidney; retain what you dont want to lose, the glucose, AAs, are reabsorbed.
merocrine secretion
secretes product by exocitosis
function of columnar
secretion and absorption
function of cuboidal
secretion and absorption
tissues with weak generation capacity
skeletal muscle and cartilage
tissues with moderate regeneration capacity
smooth muscle and dense regular connective
immune response
specific and takes longer to be effective (strep)
muscles are connected to bones by
tendons
what makes up connective tissue matrix?
the matrix and all connective tissue and connective tissue proper (loose, dense, regular, irregular)- FIBROBLASTS.
connective tissue functions
transport, mechanical support, immunological defense, growth and repair, hemopotoesis.
smooth muscle function and characteristics
uninucleated, spindle shaped, overlap. located in hallow walls of organs, and is involuntary movement, and movement of blood and urine.
skeletal muscle function
voluntary movement. they are multinucleated
adipose tissue types
white- lipid droplet for storage, all in body in each cell. brown- has many droplets, for regulating body temp.
holocrine secretion
whole cell ruptures to release product
BONE
(osseous tissue) made by osteoblasts then mature to osteocytes- function: withstand stress, compression, hardest tissue. growth and repair.
glycoaminoglycans
GAG- large negatively charged polysaccarides that trap water.
