What does the term "ossify" refer to in the development of animal bones?

The term "ossify" specifically refers to the process by which cartilage transforms into bone tissue, resulting in the development of hard, bony structures. This process is crucial during the growth and development of animals, particularly during their skeletal maturation. As the animal grows, certain areas of cartilage that initially form the skeleton gradually ossify, becoming stiffer and more supportive as the individual matures. This process ensures that the bones gain strength and durability, which is essential for supporting the weight of the animal and allowing for movement. Understanding ossification is key in fields such as veterinary medicine and animal science, as it directly relates to skeletal health and development in animals.
