hichkok12 [17]

Answer:

1. When two bones join together and fuse so that no visible separation occurs, it is referred to as a(n) <u>synostosis,</u> or bony joint.

2. Bones that join together and are held in place with threads of collagen, form a joint that is called a(n) <u>synarthrosis</u>.

3. The most complex joints are called <u>synovial</u> joints. They display varying amounts of mobility.

4. Bones joined together with cartilage between the ends of the bones, form a joint called a(n)<u> amphiarthrosis</u>.

Explanation:

The ossification of the connective tissue between two bones results in the fusion of them. As a result, now there is one bone instead of two. It's is called synostosis.

A synarthrosis is a joint that has very little or no movement at all. It has threads of collagen around them that keep the joint together.

A synovial joint is a diarthrosis joint. They have a wide range of mobility and are complex due to the number of components:

  • A fibrous joint capsule connected to the two bones.
  • A synovial membrane.
  • Synovial fluid to lubricate the joint.
  • Articular cartilage on the bones' joint surfaces.

An Amphiarthrosis is a joint with limited mobility. This type of joint has fibrocartilage that connects the two bones. We can find it in the pubic synthesis.
