“What holds all of the different parts of a skeleton together?”
Skeletons are quite complex structures. The average adult human skeleton holds around 206 individual bones in it’s composition! However, how what connects these bones all together, and what allows for their range of movement? Well, much like a mechanical machine, these bones are connected to each other through the use of elements called bone joints. Bone joints come in three different types of varieties: Fibrous (allowing for no movement between the connections,), cartilaginous (allowing for limited movement), and synovial (allowing for full movement). Fibrous joints are utilized in skull connections, cartilaginous joints in back vertebrae, and synovial joints are used in the knees.
