patella

An example of a sesamoid bone is the _____

articulations

Bones of the skeleton are connected at junctions called _______

The bone treated with acid because the acid dissolves the calcium phosphate, making the bones less rigid and prone to deformation

In a child with rickets, the bones are prone to deformities caused by a lack of calcium, phosphate, or vitamin D. Which treated bone in Activity 2 most closely resembles the bones of a child with rickets? Why?

The bones store fat, red marrow, and calcium.

In addition to supporting and protecting the body, the skeleton provides this function as well.

fibroblasts

The pain in the leg that is referred to as "shin splints" is often caused by microtears in the periosteum and perforating fibers. These tears lead to inflammation of the periosteum.
