Chemistry
occur when chemical bonds are formed, rearranged, or broken
Chemical Reactions
chemical reactions can be written in symbolic forms called
molecular formulas
this is the most abundant and widely distributed of primary tissues
connective tissue
this tissue is a sheet of cells that covers body surfaces or cavities
epithelial
box-like, cube is a description for this shape of cells
cuboidal
AB --> A+B is an example of this
Decomposition reaction
synthesis reactions
flattened and scale-like “squashed" is a description for this shape of cells
squamous
these cells (in connective tissue) Store nutrients
fat cells
these cells (in connective tissue) include: neutrophils, eosinophils, lymphocytes. They have a tissue response to injury
white blood cells
AB+C ---> AC+B is an example of this reaction
exchange reactions
A+B= AB is an example of this
synthesis reaction
When classifying epithelia, the 1st name indicates the number of cell layers. What are the 2 names?
simple epithelia (single thick layer)
stratified epithelia (2+ layers)
these cells (in connective tissue) have phogocytic cells that "eat" dead cells, microorganisms, and function in our immune system
macrophages
columnar
when bonds are both made broken (also called displacement reactions)
exchange reactions
when bonds are broke in larger molecules, resulting in smaller, less complex molecules
decomposition reactions
these cells (in connective tissue) initiate local inflammatory response against foreign microorganisms they detect
mast cells
this is a specialized nerve cells that generate and conduct nerve impulses
neuron
What are the major functions of connective tissue
•Binding and support
•Protecting
•Insulating
•Storing reserve fuel
•Transporting substances (blood)
carbs, fats, proteins and nucleic acids are what sort of compound?
organic
waters, salts, and many acids and bases are examples of what sort of compound?
inorganic
muscle cells possess________ are made up of actin and myosin proteins that bring about muscle contraction
myofilaments
muscle tissue has 3 types:
skeletal, cardiac, and smooth
these are supporting cells that support, insulate, and protect neurons
neuroglia
