30 Cards in this Set

  • Front
  • Back
Epithelial Tissue
Have sheets of very tightly capped cells. Anchored to the "basic membrane". Cover body surfaces, line internal organs and cavities.
Simple
one layer of cells
Stratified
two or more layers
Squamous (cell shape)
shaped like tiles on the floor
Columnar (cell shape)
shaped like bricks
Simple squamous epithelium
thin and leaky for exchanging material (like the air sacs in lungs)
Simple columnar
secret mucus (lining of the intestine)
Connective Tissue - Adipose
Made up of Adipocytes
Adipocytes
where body fat is found, almost the entire center is filled.
Functions of Adipocytes
1) pads organs
2) insulates body
3) stores energy
Bone- osteon
unit of structure and funtion in compact bone
Central Canal-
(Haversian Canal) center of each osteon, contains vesel.
Canalculi-
canals that remove wastes and provide nutrients ostecytes
Concentric lamellae
intercellular material that surrounds central canal.
Lacunae
depressions in the cocentric lamellae
osteocyte
bone cell located in lacunae
Erythrocytes
(red blood cells) 1) bi concave cells,lack nucleus and organelles 2) contain hemoglobin and carry oxygen
Leukocytes
(white blood cells)
Eosinphils (eosin lovers)
take up the red dye eosin, destroy parasitic worms
Basophils
affinity for blue or basic dye, release chemicals involved in inflammation.
Neutrophils
do not have an affinity for either, clear.
Monocytes
large nucleus, which is horseshoe in shape.
Lymphocytes
1) large nucleus (take up most of the cells )
2) Scampy cytoplasm
Platelets
colorless cell fragments involved in blood clotting.
Plasma
liquid portion of blood
Function of blood
1) Transport Oxygen
2) Protect body with White blood cells
3) Platelets (blood clotting)
4) Blood Transports substances through body.
skeletal cell
1)found--various areas of the body.
2)Appearance- long and straited cells.
Multinucleate
multiple nuclei- they are found on the peripheral of the cell.
Type of Control in skeletal muscles
voluntary
Cardiac tissue
1)found in the heart 2)long striated, branched and have intercalated disks
