Rabbit Dissection System

The rabbit dissection system involves a structured procedure designed to expose and study the internal and external anatomical features and organ systems of a rabbit (Oryctolagus cuniculus) for educational purposes.​

Dissection Procedure

The preserved rabbit is placed ventral side up in a dissecting tray and secured with tied limbs or pins to prevent movement during dissection.​

An incision is made along the midline from the sternum (breastbone) to the pelvis, first through the skin and then the muscle layer.​

Skin and muscle flaps are reflected and appropriately pinned, exposing the peritoneum—a thin membrane lining the abdominal cavity—which is then cut to reveal the abdominal organs.​

Additional incisions through the ribs and breastbone allow access to the thoracic cavity, separating it from the abdomen via the diaphragm.​

Systems Studied

Digestive System: After opening the body cavities, organs such as the liver (with multiple lobes), gallbladder, stomach, spleen, small and large intestines, pancreas, and associated ducts are examined for structure and function.​

Respiratory System: The thoracic cavity contains the lungs and trachea, separated from the abdomen by the diaphragm, which plays a key role in breathing.​

Circulatory System: Careful removal of the thymus (overlying the heart) and pericardium exposes the heart, major vessels, and lungs for study of blood flow and oxygenation.​

Urogenital System: Kidneys, ureters, bladder, and reproductive organs (testes, ovaries, uterus, etc.) are located and studied in the abdominal cavity.​

Muscular and Skeletal System: The guide includes analysis of skeletal features and dorsal/ventral muscles, using diagrams to highlight bone and muscle names.​

Key Features

The rabbit dissection provides a comparative model for mammalian anatomy and is used to identify, differentiate, and understand the structure and function of all major organ systems.​

Safety and ethical guidelines are followed for specimen handling, with procedures including use of gloves, tools, and careful disposal of tissues.​

This system enables detailed exploration of rabbit anatomy, helping students and researchers understand mammalian physiology and organ relationships.​
