The initial step in tissue processing that uses formaldehye to preserve cell structures and harden the tissue for easier cutting.

The process of gradually removing water from the tissue using increasing concentrations of alcohol, preparing it for paraffin wax.

The process of removing alcohol from the tissue using a clearing agent like xylene, making the tissue transparent for wax infiltration.

The process of replacing the clearing agent with molten paraffin wax, allowing the tissue to become embedded in the wax for cutting.

A method of embedding tissue in paraffin wax that involves placing the tissue in a wax bath at a specific temperature and changing the wax at intervals.

A medium used for infiltration that turns solid at room temperature, making it easier to cut tissue sections.

The temperature at which a substance changes from solid to liquid. For paraffin wax, it's 56 degrees Celsius.

An automated machine used for processing tissues. It automatically completes the first 4 steps including fixation, dehydration clearing, and infiltration.

Using heat to speed up the process of filling tissue spaces with paraffin wax.

Creating a negative pressure inside the oven to accelerate the penetration of paraffin wax into tissue spaces.

The process of moving the tissue around within the wax solution to ensure that all areas are fully infiltrated.

Repeated changes of fresh paraffin wax to ensure complete removal of the clearing agent and thorough penetration of the wax into the tissue.

This method involves replacing water in tissue with a supporting medium like paraffin wax, allowing for thin tissue sectioning.

A type of wax used for embedding, typically with a lower melting point but harder consistency.

Recommended for bones and brain specimens due to its suitability for harder tissues.

A water-soluble wax, eliminating the need for clearing and dehydration steps. Useful for enzyme studies.

A method of embedding tissues using celloidin, a type of nitrocellulose, as the supporting medium.

A specialized process where a leather strop is used to polish and refine the sharp edge of a knife, removing burrs and irregularities after honing.

The process of flattening ribbons of tissue by removing creases and wrinkles using a float out bath.

The act of carefully removing the tissue ribbons from the float out bath without disturbing their structure.

The specific placement of tissue ribbons in the centre of a slide, ensuring proper alignment for further processing.

A type of oil that should not be used on leather strops because it can damage the leather, causing blisters or deterioration.

The process of embedding a tissue sample in a mold filled with a solid medium, like paraffin wax or resin, to create a block for sectioning.

A solid material, like paraffin wax or plastic resin, that is used to solidify around a tissue sample during embedding.

A container used to hold the tissue sample and embedding medium during the embedding process.

A specific type of embedding mold made with two L-shaped parts that can be fitted together to hold a tissue sample.

A commonly used chemical in embedding solutions to prevent the growth of mold and maintain the quality of the tissue blocks.

A type of embedding medium that uses gelatin to solidify around the tissue sample, providing a pliable and flexible block for sectioning.

The purpose of formalin in gelatin embedding is to harden the tissue before cutting. It is not used as a fixative.

The process of embedding can be referred to as casting or blocking, as it results in creating a tissue block that is ready for sectioning.

A manual method of embedding where tissue is placed in a mold filled with melted paraffin, then cooled rapidly, allowing for quick and easy orientation.

A type of mold that consists of interconnected plates, allowing the user to create multiple blocks of tissue simultaneously.

A plastic embedding ring designed specifically for embedding tissues in paraffin wax; commonly used with Bass molds.

A specific type of embedding mold that incorporates a base and removable plates, providing a convenient way to create multiple blocks of tissue.

A tool used for embedding tissues using paraffin wax, allowing for easy removal of the block once it solidifies.
