Rat dissection: Organs and their functions + Dissection tools

Scalpel

used for precision cutting

T-Pins
used to position or identify parts of a dissected organism.

Dull Probe
used to manipulate specimens and probe openings

Small Dissecting Scissors

used to cut skin and tissues. Keep the blades at a shallow angle when cutting into an organism to prevent damage to internal structures

Dissecting Needle
multi-purpose tool that can be used to manipulate, probe, or clean parts of specimens

Razor Blade
used for precision cutting, particularly when you need to be very meticulous in your cutting

Forceps

used for grasping and manipulating parts of an organism during a dissection

Neck vertebrae, including the Atlas (C1), which supports the skull, and the Axis (C2), which allows head rotation.

Thoracic vertebrae

Vertebrae in the chest region that attach to the ribs.

Lumbar vertebrae:
