pathology

is a study of the changes occurring in tissues during disease, including both the structural or morphological changes and molecular abnormalities

pathology

addresses the causes and mechanisms by which these abnormalities develop, and their functional consequences

observation

considered as the heart of pathology, as it is for many other disciplines, it is a skill that can be developed with practice and aided by knowledge

lesions

any observable change in a tissue if it is considered to be abnormal

rigor mortis

postmortem contraction of striated, smooth and cardiac muscle which results in stiffening of the carcass during 1 to 6 hours after death

hypostatic congestion

involves the gravitational pulling of blood after death depending on the position of the body

hemoglobin imbibition

commonly seen in carcasses subjected to freezing and thawing, and in autolyzed fetuses, we've breakdown of red blood cells and diffusion of hemoglobin causing red staining of tissues

putrefaction

can induce green black discoloration of tissue (pseudomelanosis) due to the breakdown of blood and formation of iron sulfides

description

the basis of scientific communication, by which we are able to share information about lesions or diseases
