What kind of tissue is the forerunner of long bones in the embryo? elastic connective tissue dense fibrous connective tissue fibrocartilage

The forerunner of long bones in the embryo is primarily formed from fibrocartilage. This cartilage serves as a template for ossification, where it will eventually be replaced by bone as the embryo develops. The process, known as endochondral ossification, is crucial in forming the skeletal system we rely on! As these long bones develop, they go through fascinating transformations, starting as a flexible cartilage model, which allows for growth and movement before becoming the hard bone structure we know. It's like watching a sculptor at work, gradually turning a soft lump of clay into a masterpiece!
