none
Kidney Tubules, ovary surface
secretion and absorbtion
Simple Columnar Structures Cell Location Function
none
goblet cells
digestive tract
absorbtion/ secretion of mucus - propels mucus
Stratified Squamous Structures Cell Location Function
none
none
lining of esophagus, mouth, vagina, skin
protects underlying tissue
Ciliated PSEUDOSTRATIFIED columner Structures Cell Location Function
cilia goblet cell ciliated - trachea and upper respiratory non ciliated - spem ducts secret mucus, propels mucus
Dense Connective Tissue Structures Cell Location Function
collagen fibers
fibroblast
tendons, most ligaments, aponeuroses
attaches muscle to bone/ great tensile strength
Adipose Structures Cell Location Function
fat globule
nucleus
adipocyte
subcu tissue, around kidney and eyeballs, abdomen and breasts
provides reserve feul, insulates body and protects organs
Reticular Structures Cell Location Function
reticuar fibers
reticulocyte
lymphoid organs, lymph nodes, bone marrow, spleen
fibers form soft internal skelaton - stoma- that supports other cells
Areolar connective Structures Cell Location Function
collegen fiber - pink lines
elastic fiber - thin dark lines
fibroblast cell
around organs under skin
hold tissue fluid, wraps and cushons organs, under skin/epithelia
Elastic Cartilage Structures Cell Location Function
matrix, lacuna, elastic fibers
Chodrocytes
supports external ear and epiglottis
maintains shape and structure with flexibility
Hyaline Cartilage Structures Cell Location Function
Matrix, lacuna
chondrocyte
embryonic skelaton, covers ends of long bones, coastal cartilage of ribs, cartilage of nose, tachea and larynx
supports, reinforces, cushons, resists compressive stres
Fibrocartilage Structures Cell Location Function
matrix, lacuna, collagen fiber
chondrocytes
intervertebral disc, pubic symphysis, discs of knee joint
absorbs compressive shock
Bone Structures Cell Location Function
Haversian canal, lacuna, canaliculi, lamellae, matrix, osteon
osteocyte
diaphysis of compact bone
supports, protects, hematopoises, stores minerals, provides for muscles
Skeletal Muscle Structures Cell Location Function
striation, muscle fiber, voluntary
none
attached to bone or skin
voluntary movement
Cardiac Muscle Structures Cell Location Function
striation, muscle fiber, voluntary, intercalated discs
none
walls of heart
propels blood
smooth muscle Structures Cell Location Function
non striated, involuntary
none
walls of hollow organs
propels subtances - food, urine, babies
Nervous Tissue
cell body, axon, dendrite
neuron, neurogila
brain, spinal cord
tansmists signals
interphase
dna replication, normal activities
prophase
1st stage, chromosomes duplicate consistine of 2 sister chroatids
metaphase
Chromosomes align along the middes, 2 centersomes are at opposite poles
anaphase
3rd stage, centromeres split, each chromatid becomes its own chromosome
telophase
chromosomes uncoild, resume chromatin form
