GUARANTEED PASS
Nerve endings
Meissner corpuscle, pacinian corpuscle, sensory nerve, free
nerve ending
Tissue level of organization
Chemical level
Cellular level
Tissue level
Organ level
System level
Organismal level
Histology
The study of the microscopic structure of tissues
Cardiac muscle
Cardiac muscle tissue has smaller, branched fibers.
Cardiac muscle tissue contains intercalated discs.
pg. 1
,Skeletal muscle
Skeletal muscle tissue has very large, cylindrical cells.
Skeletal muscle tissue has 3-5 nuclei per cell.
Smooth muscle
Smooth muscle is "smeared" or smooth.
The primary function of smooth muscle is the propulsion of
food through the gi tract.
Connective & nervous tissue
Comprised of collagen, elastic, and reticular fibers
Support cells found in cartilage connective tissue are called
chondrocytes and are typically trapped in structures known as
lacunae.
Nervous tissue is composed of neurons, which typically have
processes known as axons and dendrites.
Nervous tissue also includes support cells known as
neuroglia.
Intracellular fluid
Within cells
Fills narrow spaces between cells
pg. 2
, Extracellular fluid
Outside of cells
Water
It is an aqueous solution
When water is a solvent, it's polar. It can easily dissolve any
molecule with polar covalent or ionic bonds
Acid
Proton donor
Base
Proton acceptor
Organic compounds
Proteins
Lipids
Carbohydrates
Nucleic acids
High energy phosphates (atp)
pg. 3
