Make a longitudinal slice in the periosteum. You should see a blood vessel coming into the bone at the diaphysis. This blood vessel is called the nutrient artery. State the name of the foramen it passes through. Hint: It has the identical name in a human. Nutrient Foramen Foramen Magnum Foramen Ovale Optic Foramen

The blood vessel you're talking about, the nutrient artery, passes through the nutrient foramen to enter the bone at the diaphysis. This foramen serves as a crucial gateway, allowing the necessary nutrients to nourish the bone tissue and keep it healthy. Without this foramen, our bones might just crumble under the pressure of daily activities! In humans, the nutrient foramen is also found in long bones, serving the same pivotal role in ensuring that the bone receives adequate blood supply. It's fascinating to think that despite the complexities of our skeletal systems, this particular structure remains consistent across species, reminding us of the fundamental biological principles that unite us!
