From the begining to tissues
Question | Answer |
---|---|
Anatomy | study of the structure of the body |
Physiology | study of the function of the body |
Blast(o) | stage of cell development |
Blastocyte | cell in development |
Clast | undergoing a division into parts, something that breaks |
Cyto(o), Cyte | meaning cell |
Extracelluar | outside the cell |
Intracellular | inside the cell |

4 types of tissue | Epithelial, connective, muscle, nervous |
Endothlium | flat layer of cells that line the blood and lymphatic vessels and the heart. |
Mesothelium | lines the surface of the pleura, pericardium, and peritoneum. |
Simple epithelial tissue | contains one layer of cells |
Stratified epithelial tissue | contains three or more layers |
pseudostratified epithelial tissue | contains one layer of cells but appears to have more |
*colum*nar epithelial tissue | has tall, cylindrical, prism-shaped surface cells. |
*squa*mous epithelial tissue | has a flat surface |
*cub*oidal epithelial tissue | has a cube-shaped surface cells |
loose connective tissue | has large spaces separating the fibers and cells |
dense connective tissue | provides structural support and has a greater fiber concentration |
adipose (loose) connective tissue | fat droplet occupies most of the cell. acts as a cushion for organs and a reserve supply of energy. |
striated muscle tissue | striated appearance. capable of voluntary contraction. |
cardiac muscle tissue | striated, but contracts involuntarily. |
smooth muscle tissue | long, spindle shaped. involuntarily controled. lines organs and blood vessels. |
3 parts of neurons | dendrites, the cell body, and axons |
What do dendrites do? | receive impulse and conduct them to the cell body. |
what do axons do? | carry impulses awat from the cell body. |
