Cells such as basophils, fibroblasts, lymphocytes, monocytes, and macrophages play key roles in skin structure and wound repair.

Rubor refers to redness, one of the cardinal signs of inflammation caused by increased blood flow.

The four original signs of inflammation: rubor (redness), tumor (swelling), calor (heat), and dolor (pain), with loss of function added later.

Vasodilation is the widening of blood vessels, leading to increased blood flow and contributing to redness and heat in inflammation.

Acute inflammation involves the body's immediate response to harmful stimuli, characterized by increased blood flow and permeability.

Exudates are fluid containing proteins, immune cells, and debris that leaks into tissues during inflammation due to increased vascular permeability.

Histamine increases vascular permeability, allowing immune cells to access injured sites, playing a crucial role in inflammatory response.

Mast cells are the most likely source of histamine in the body, leading to increased vascular permeability during inflammation.

Cells lining blood vessels involved in inflammation.

A cell that produces collagen and other fibers in connective tissue.

A type of white blood cell pivotal in immune response.

Cells that release chemicals like histamine during inflammation.

White blood cells that are first responders to sites of infection.

Inflammation characterized by the presence of pus.

Inflammation with a watery, low-protein fluid outpouring.

Increase in cell size due to increased workload or stimulation.

An apparent increase in size without actual increase in cell size.

Increase in size of an organ due to increased workload or loss of another organ.

An increase in the size of individual cells leading to tissue growth.

Reversible change where one cell type transforms into another.

A type of necrosis characterized by cheese-like appearance of dead tissue.

Necrosis where cell outlines remain, but internal details are lost.

Abnormal growth or development of cells, often pre-cancerous.

A condition where fat accumulates within cells, particularly seen in the liver due to injury or toxins.

A classification indicating a cytological picture suggestive but not conclusive of malignancy.

A classification indicating a cytological picture strongly suggestive of malignancy.

A classification which indicates a cytological picture that is benign and unlikely to show malignancy.

Cancers that originate from epithelial tissues and usually have a lesser tendency to produce stroma compared to benign tumors.

A type of necrosis characterized by a transformation of tissue into a liquid viscous mass, often due to bacterial infection.

A virus causing clear vesicles and multinucleated giant cells with intranuclear inclusions.

Large cells containing multiple nuclei, often seen in infections.

A term describing the appearance of the nuclei in certain viral infections, indicating viral effects.

Abnormal structures within the nucleus caused by viral infections, such as HSV.

Programmed cell death, a normal process for cellular turnover.

Uncontrolled cell death due to injury or disease, often causing inflammation.

The biological aging of cells where they no longer divide.

The final stage of cell specialization where cells can no longer divide.

A process of rapidly cooling a substance.

Transition from solid to gas without becoming liquid.

Quenching at –160C, sublimation at –40C.

Fixation is the first critical step.

The brain must be fixed before sectioning.

To preserve the morphologic and chemical integrity of the cell.

To harden and protect tissue from trauma.

Traditionally, 10 to 25 times the volume of tissue.
