|
Epithelial Tissue
|
Type of tissue composed of one or more layers of closely adhering cells
-covers an organ or forms the secretory tissue and ducts of a gland -barely visible on light microscope -no blood vessels |
|
|
Connective Tissue
|
A type of tissue in which cells usually occupy less space than extra-cellular material
-binds organs together -support & protect organs -cells in connective tissue aren't in direct contact with eachother |
|
|
Nervous Tissue
|
Specialized for rapid communication by means of electrical and chemical signals
-consists of neurons & much greater numbers of supportive neuroglia which help to support and protect neurons -neurons are specialized to detect stimuli, respond quickly and transmit information rapidly to other cells |
|
|
Muscle Tissue
|
contracts when stimulated and exerts force on other tissues
-Skeletal - voluntary, striated -Cardiac - involuntary, striated -Smooth - involuntary, not striated |
|
|
Factors required to make engineered organs
|
-cells
-scaffold -mechanical stimulation -growth factors/cytokines |
|
|
1 degree protein structure
|
linear sequence of amino acids in the protein, order in which amino acids are added during synthesis
|
|
|
2 degree protein structure
|
3D structure of proteins that groups amino acids into functional domains (alpha helix, beta sheet, loop)
|
|
|
3 degree protein structure
|
3D structure that takes into account the interaction between different 2 degree structures; provides specific spatial coordinates for every atom in the protein
|
|
|
4 degree protein structure
|
protein:protein interactions
|
|
|
Nucleus
|
-control center of the cell
-contains genetic information |
|
|
Ribosomes
|
-sites of protein synthesis
|
|
|
Endoplasmic Reticulum
|
-protein folding & post-translational modification
-lipid synthesis |
|
|
Golgi Apparatus
|
-Further post-translational modification of proteins
-prepares for protein export |
|
|
Mitochondrium
|
-major metabolic organelle
-important in ATP formation -converts between fats, sugars and proteins |
|
|
lysosome
|
-low pH organelle
-degrades old or damaged organelles |
|
|
proteasome
|
-protein degradation
|
|
|
plasma membranes
|
-lipid bilayer that separates the cytoplasm & organelles from the exteral environment capitor
|
|
|
cytoskeleton
|
-provides 3D cell shape & motility
|
