What does tonic mean biology?
Tonic in physiology refers to a physiological response which is slow and may be graded. This term is typically used in opposition to a fast response.
What does tonic mean in anatomy?
Medical Definition of tonic (Entry 1 of 2) 1a : characterized by tonus tonic contraction of muscle also : marked by or being prolonged muscular contraction tonic convulsions. b : producing or adapted to produce healthy muscular condition and reaction of organs (as muscles)
What is the tonic solution?
Hypertonic solution: A solution that contains more dissolved particles (such as salt and other electrolytes) than is found in normal cells and blood. For example, hypertonic solutions are used for soaking wounds.
What is hypertonic vs hypotonic?
A hypotonic solution is one in which the concentration of solutes is greater inside the cell than outside of it, and a hypertonic solution is one where the concentration of solutes is greater outside the cell than inside it.
Are tonics alcoholic?
If you’ve ever had a sip of straight tonic water, without gin or vodka or any other liquors, you know that tonic water is not seltzer, or even club soda. The bitterness you taste when you drink tonic water comes from one ingredient: quinine.
What is an example of hypertonic?
An example of a hypertonic solution is the interior of a red blood cell compared with the solute concentration of fresh water. When two solutions are in contact, solute or solvent moves until the solutions reach equilibrium and become isotonic with respect to each other.
What is tonic in music theory?
tonic, also called keynote, in music, the first note (degree) of any diatonic (e.g., major or minor) scale. It is the most important degree of the scale, serving as the focus for both melody and harmony.
What is the example of tonic?
Tonic is defined as something that stimulates or excites, or a type of carbonated drink. An example of a tonic is a drug. An example of tonic is a beverage often mixed with gin. (music) The first note of a diatonic scale; the keynote.
What is hypertonic cell?
If a cell is placed in a hypertonic solution, there will be a net flow of water out of the cell, and the cell will lose volume. A solution will be hypertonic to a cell if its solute concentration is higher than that inside the cell, and the solutes cannot cross the membrane.
What is example of hypertonic?
A hypertonic solution is one which has a higher solute concentration than another solution. An example of a hypertonic solution is the interior of a red blood cell compared with the solute concentration of fresh water.
What is isotonic in biology?
Isotonic solution: A solution that has the same salt concentration as cells and blood.
What is hypotonic cell?
In biology, a solution outside of a cell is called hypotonic if it has a lower concentration of solutes relative to the cytosol. Due to osmotic pressure, water diffuses into the cell, and the cell often appears turgid, or bloated.
