|
Cell's major components |
plasma membrane, cytoplasm, nucleus, & nucleolus |
|
|
Organelles |
rough endoplasmic reticulum (RER)/ smooth endoplasmic reticulum (SER)/ Golgi complex/ mitochondria |
|
|
Rough endoplasmic reticulum (RER) |
protein synthesis |
|
|
Smooth endoplasmic reticulum (SEM) |
lipid synthesis & detox |
|
|
Golgi complex |
modifies and packages protein |
|
|
mitochondria |
produce ATP "powerhouse" of cell |
|
|
Cilia & Flagella |
both are composed of microtubules / capable of movement, continuing ATP |
|
|
Cilia |
are numerous and are on the surface of some body cavities (transport mucus in trachea, oocyte in the uterine tube.) |
|
|
Flagella |
occurs only on sperm (move back & forth)/ visible with LM |
|
|
Micovilli |
much smaller than cilia/ not visible with LM appears as a brush border |
|
|
Micovilli |
increase surface area for absorption/ small intestine/ proximal convoluted tubule of the nephron (kidney) Not motile |
|
|
Tissues |
groups of similar cells and extracellular matrix that carry out a common function |
|
|
Tissues four types |
epithelium, connective tissue, muscle, & nerve/ extracellular matrix - fibers + interstitial fluid |
|
|
Characteristics of epithelia |
mostly cells/ basement membrane/ avascular : no blood vessels/ polarity/ high regenerative capacity |
|
|
Simple squamous epithelium |
single layer of flat cells / aveoli in lungs, lining blood vessels / flatten nucleus, little cytoplasm |
|
|
Simple cuboidal epithelium |
single layer of cells with similar width and height / spherical nucleus/ transport secretion/ location; kidney tubules, ducts of glands |
|
|
Simple columnar epithelium |
single layer of tall cells / oval nucelus at basal region/ functions in secretion and absorption/ may contain cilia or microvilli/ location: digestive tract (small intestine on right uterine tubes) |
