Study Notes

Inflammation

Acute inflammation is characterized by the presence of polymorphonuclear cells.
The five classic signs of acute inflammation are:
Redness
Swelling
Heat
Pain
Loss of function

Purpose of Inflammation

The purpose of inflammation is to protect the body from injury or infection.

Vascular Permeability

Increased vascular permeability is influenced by factors such as histamine, bradykinin, and leukotrienes, but NOT by albumin.

Transudate and Exudate

The main difference between transudate and exudate is that transudate is a clear fluid with low protein content, while exudate is a cloudy fluid with high protein content.

Cellular Response

The steps in the cellular response during inflammation do NOT include fibroblast activation.

Neutrophils

The function of neutrophils' tertiary granules is to degrade extracellular matrix components.

Cell Division

Mitosis is the process of cell division that results in two identical daughter cells with the same number of chromosomes as the parent cell.
Meiosis is the process of cell division that results in four non-identical daughter cells with half the number of chromosomes as the parent cell.

Genetics

Polygenic inheritance is characterized by the interaction of several genes and is not a Mendelian inheritance pattern.
The term used to describe the identification of genetic disorders in families through the analysis of family trees is pedigree analysis.
The inheritance pattern that is NOT Mendelian is polygenic inheritance.

Meiosis

During meiosis, genetic diversity is generated through two processes: crossing over and independent assortment.
Crossing over involves the exchange of genetic material between homologous chromosomes.
Meiosis is the process of cell division that results in four non-identical daughter cells with half the number of chromosomes as the parent cell.

Fertilization

The process of fertilization involves the fusion of a sperm cell with an egg cell, resulting in the formation of a zygote.
