Tonicity in Animals00:59

Tonicity in Animals

The tonicity of a solution determines if a cell gains or loses water in that solution. The tonicity depends on the permeability of the cell membrane for different solutes and the concentration of nonpenetrating solutes in the solution within and outside of the cell. If a semipermeable membrane hinders the passage of some solutes but allows water to follow its concentration gradient, water moves from the side with low osmolarity (i.e., less solute) to the side with higher osmolarity (i.e.,...
Oogenesis02:07

Oogenesis

In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...

Test Cross

Alleles are different forms of the same gene. Humans and other diploid organisms inherit two alleles of every gene, one from each parent.
Tonicity in Animals01:16

Tonicity in Animals

Tonicity describes the amount of solute in a solution. The measure of the tonicity of a solution, or the total amount of solutes dissolved in a specific amount of solution, is called its osmolarity. Three terms—hypotonic, isotonic, and hypertonic—are used to relate the osmolarity of a cell to the osmolarity of the extracellular fluid that contains the cells. In a hypotonic solution, such as tap water, the extracellular fluid has a lower concentration of solutes than the fluid inside the cell,...
Ascites01:19

Ascites

DefinitionAscites is the buildup of fluid inside the peritoneal cavity. It occurs when fluid moves out of the vascular system faster than the peritoneal lymphatics can remove it. This fluid shift is most commonly seen in liver cirrhosis but can also appear in several other systemic disorders.EtiologyCirrhosis remains the leading cause of ascites. Other conditions that can contribute include:Heart failureConstrictive pericarditisAbdominal cancersNephrotic syndromeSevere protein–calorie...

Resumen
Este resumen es generado por máquina.

Las vías de picazón son distintas del dolor, con nuevas clasificaciones que diferencian las causas periféricas y centrales. Los avances en la comprensión de la neuropatofisiología de la picazón conducen a una mejor evaluación y tratamientos para este síntoma común.
