What is the function of the nucleus?
Stores and protects DNA
What is cytoplasm?
Fluid contained in the cell membrane which is made of water, electrolytes,
proteins, facts, glycogen, etc.
What is the cell membrane made up of?
Phospholipids and cholesterol
What is the function of the cell memebrane?
Provides receptors for hormones and other biologically active substances,
participates in the electrical events that occur in nerve and muscle cells, and aids
in the regulation of cell growth and proliferation
What is autocrine signaling?
A mode of hormone action in which a chemical messenger acts on the same cell
that secretes it
What is paracrine signaling?
Mode of hormone action that acts on nearby cells
What is endocrine signaling?
hormones released from a cell affect other cells throughout the body by relying
on the bloodstream. Mainly occurs in the pancreas
What is synaptic signaling?
Neurotransmitters act only on adject nerve cells. Occurs in the nervous system
What is passive transport?
, The movement of materials across the cell membrane without using cellular
energy (diffusion, osmosis, facilitated diffusion)
What is active transport?
the movement of molecules across a cell membrane into a region of higher
concentration, assisted by enzymes and requiring energy (primary active
transport)
What is diffusion?
Movement of solutes from an area of greater concentration to an area of lesser
concentration
What is osmosis?
Movement of water from a low concentration of solute to a high concentration of
solute
How do you achieve serum osmolality homeostasis?
Water will move from an area of low osmolality to an area of high osmolality
When is osmolality decreased?
When there is a decreased of particles or excess fluid (SIADH, liver cirrhosis,
nephrotic syndrome, heart failure)
When is osmolality increased?
There are too many solutes in the serum (BP disturbances, dehydration, diabetes
insipidus)
What is the difference between osmolality and osmolarity?
Osmolality is the measurement of dissolved particles, whereas osmolarity is the
number or particles per liter of solute
What is filtration?
