Summary

TLDRThis script delves into the anatomy of a dog's thorax and abdomen, highlighting the skeletal structure including the skull, vertebrae, ribs, and limb bones. It describes the thoracic and abdominal boundaries formed by the rib cage, diaphragm, and vertebral column. The script details the positioning of vital organs such as the heart, lungs, liver, and kidneys, and guides through the process of identifying them upon removal of the diaphragm and liver. It also mentions the visibility of the gastrointestinal tract, reproductive organs, and urinary bladder when the abdomen is viewed from the ventral aspect.

Takeaways

  • 🦴 The anatomy of a dog's thorax and abdomen involves envisioning structures beneath the skin and the relevant parts of the skeleton.
  • 💀 The skeletal components include the skull, cervical, thoracic, lumbar, and coxial vertebrae, as well as the rib cage, pelvis, and bones of the thoracic and pelvic limbs.
  • 🐾 Thoracic limbs consist of the scapula, humerus, radius, ulna, carpus, metacarpus, and digits.
  • 🦿 Pelvic limbs are made up of the femur, tibia, fibula, tarsus, metatarsus, and digits.
  • 🔢 The thoracic vertebrae are associated with 13 pairs of ribs, the sternum, and the diaphragm, which together form the boundaries of the thorax.
  • 🧘 The diaphragm, along with the ventral abdominal wall and pelvis, defines the boundaries of the abdomen.
  • 🫁 The lungs extend from the level of the first rib to the 10th rib.
  • ❤️ The heart is obliquely positioned in the thorax, from the third to the sixth intercostal spaces.
  • 🧇 The large, dome-shaped diaphragm separates the thoracic cavity from the abdomen.
  • 🍗 Removal of the diaphragm reveals the liver and gallbladder, with the liver spanning the entire width of the dog.
  • 👀 After removing the liver, other organs such as the stomach, spleen, and left kidney become more visible on the left side of the abdomen.
  • 🔍 On the right side, the duodenum, pancreas, and right kidney are evident, and from the ventral aspect, the cecum, ascending, transverse, and descending colons, rectum, ovaries, uterus, and urinary bladder can be identified.
