Dissection Procedure

Dissecting a cat is a valuable learning experience that provides insights into the anatomy and physiology of mammals. To ensure a successful and safe dissection, it is crucial to follow the proper procedures and use the necessary materials.

Materials Needed

• Preserved cat specimen
• Dissection tray or pan
• Scalpel
• Scissors
• Forceps
• Probes
• Ruler or measuring tape
• Gloves
• Apron or lab coat
• Safety glasses

Step-by-Step Dissection Guide

External Examination

1. Observe the external features of the cat, including its size, shape, fur, and any visible injuries or abnormalities.
2. Measure the cat’s body length and weight.
3. Identify the major anatomical landmarks, such as the head, neck, trunk, limbs, and tail.

Internal Examination

1. Make a midline incision along the ventral surface of the cat from the chin to the pubic bone.
2. Carefully reflect the skin and muscle layers to expose the internal organs.
3. Identify and examine the major organs, including the heart, lungs, liver, stomach, intestines, kidneys, and reproductive organs.

Specific Dissection Techniques

• Scalpel:Use a sharp scalpel to make precise incisions through skin and muscle.
• Scissors:Use scissors to cut through tougher tissues, such as tendons and ligaments.
• Forceps:Use forceps to hold and manipulate tissues, especially delicate ones.
• Probes:Use probes to gently explore and identify structures within the body cavity.

Throughout the dissection, it is important to proceed carefully and methodically, following the instructions and paying attention to detail. Proper handling of the specimen and the use of appropriate dissection techniques will ensure a successful and educational experience.

Worksheet Answer Key

This answer key provides detailed responses to the questions in the cat dissection worksheet, organized by section to correspond with the dissection procedure.

External Anatomy

• Identify the following external anatomical structures:
  • Head: muzzle, eyes, ears, vibrissae (whiskers)
  • Trunk: neck, thorax, abdomen, tail
  • Limbs: forelimbs (front legs), hindlimbs (back legs), paws, claws
  • Genitalia: male or female reproductive organs
• Describe the function of each structure:
  • Head: sensory organs, food intake
  • Trunk: contains internal organs
  • Limbs: locomotion, support
  • Genitalia: reproduction

Body Cavity

• Identify the following body cavities:
  • Thoracic cavity: contains heart and lungs
  • Abdominal cavity: contains digestive organs, liver, kidneys
  • Pelvic cavity: contains reproductive organs and urinary bladder
• Describe the function of each body cavity:
  • Thoracic cavity: protects heart and lungs
  • Abdominal cavity: protects digestive organs
  • Pelvic cavity: protects reproductive organs and urinary bladder

Respiratory System

• Identify the following respiratory structures:
  • Lungs: primary organs of respiration
  • Trachea: carries air to and from lungs
  • Bronchi: branches of trachea leading to lungs
  • Diaphragm: muscle separating thoracic and abdominal cavities
• Describe the function of each respiratory structure:
  • Lungs: exchange of oxygen and carbon dioxide
  • Trachea: conducts air
  • Bronchi: conduct air to lungs
  • Diaphragm: aids in breathing

Safety Precautions

When performing a cat dissection, it is crucial to prioritize safety. Understanding and adhering to the necessary precautions ensures a safe and productive learning experience.

Potential hazards during a cat dissection include sharp instruments, biological materials, and chemical preservatives. To mitigate these risks, follow these guidelines:

Sharp Instruments

• Handle scalpels and scissors with utmost care, always cutting away from yourself.
• Never leave sharp instruments unattended or point them towards anyone.
• Dispose of used blades in designated sharps containers.

Biological Materials

• Wear gloves and a lab coat to minimize contact with biological materials.
• Wash your hands thoroughly before and after handling cat tissues.
• Dispose of all biological waste in biohazard bags.

Chemical Preservatives

• Handle chemical preservatives, such as formalin, with care.
• Avoid inhaling fumes or spilling chemicals on skin or clothing.
• Use fume hoods when working with volatile chemicals.

Ethical Considerations

Animal dissection is an important educational tool that allows students to learn about the anatomy and physiology of animals. However, it is important to remember that animals are sentient beings, and we must treat them with respect.

The following are some ethical considerations that should be kept in mind when performing animal dissection:

Use of Animals

• Only use animals that have been ethically sourced and euthanized.
• Do not use animals that are endangered or threatened.
• Use the minimum number of animals necessary for the educational purpose.

Respect for the Animal

• Treat the animal with respect before, during, and after the dissection.
• Do not cause unnecessary pain or suffering to the animal.
• Dispose of the animal’s remains in a respectful manner.

Educational Purpose

• Use the dissection as an opportunity to learn about the animal’s anatomy and physiology.
• Do not use the dissection as a form of entertainment or amusement.
• Share your knowledge of animal anatomy and physiology with others.
