Anatomy of the Rat, Rat dissection pre lab answer key

The major anatomical structures of the rat include:

• Head: Contains the brain, eyes, ears, nose, and mouth.
• Neck: Connects the head to the body.
• Thorax: Contains the heart and lungs.
• Abdomen: Contains the digestive organs, liver, and kidneys.
• Limbs: Used for locomotion.

Brain	Head	Controls the body’s functions.
Eyes	Head	Used for vision.
Ears	Head	Used for hearing.
Nose	Head	Used for smelling.
Mouth	Head	Used for eating and drinking.
Heart	Thorax	Pumps blood throughout the body.
Lungs	Thorax	Exchange oxygen and carbon dioxide with the blood.
Liver	Abdomen	Filters the blood and produces bile.
Kidneys	Abdomen	Filter the blood and produce urine.

Dissection Techniques

Proper dissection techniques are essential for a successful rat dissection. These techniques include:

• Using sharp dissecting tools.
• Making clean, precise cuts.
• Handling the rat specimen gently.
• Preserving the rat specimen in a moist environment.

Different dissection tools are used for different purposes. Scalpels are used for making cuts, scissors are used for cutting through tough tissues, forceps are used for grasping and manipulating tissues, and probes are used for exploring small spaces.

It is important to handle the rat specimen gently to avoid damaging the tissues. The specimen should be kept moist at all times to prevent it from drying out.

Safety Precautions

The following safety precautions should be followed during a rat dissection pre lab:

• Wear gloves, safety goggles, and an apron.
• Use sharp dissecting tools carefully.
• Dispose of the rat specimen and all materials properly.
• Wash your hands thoroughly after the dissection.

Precaution	Reason
Wear gloves, safety goggles, and an apron.	To protect yourself from contact with the rat specimen and its fluids.
Use sharp dissecting tools carefully.	To avoid cutting yourself.
Dispose of the rat specimen and all materials properly.	To prevent the spread of disease.
Wash your hands thoroughly after the dissection.	To remove any bacteria or other contaminants from your hands.
