ch. 8 questions

Two bones joined by dense regular collagenous connective tissue form a __________.

fibrous joint; The predominant protein fiber in a fibrous joint is collagen.

The joint between the atlas and the axis is an example of a ____________.

pivot joint

An epiphyseal plate is an example of a __________.

synchondrosis; Examples of synchondroses include the epiphyseal plates in growing long bones as well as the first sternocostal joint and costochondral joint.

Eversion is a movement in which __________.

the plantar surface of the foot rotates laterally (opposite of inversion)

Synovial joints are __________

diarthroses

A synarthrosis that forms between adjacent bones of the skull is called a __________.

suture

Once the cranial bones reach skeletal maturity, they are joined by:

synarthroses to protect the underlying brain; The bones of the mature skull are joined by joints functionally classified as synarthroses, or immovable joints. The sutures between skull bones are interlocked and become fused once an individual reaches skeletal maturity. This is important because these joints have evolved for protection of the underlying brain. If these joints were freely movable or even slightly moveable, this protective function would be compromised.

The most moveable fibrous joints are the __________.

syndesmoses; Syndesmoses are amphiarthroses. They allow a limited amount of movement in that the articulating bones are able to pivot around one another.

A joint that allows only a small amount of movement is called a(n) __________.

amphiarthrosis; Examples include symphyses and syndesmoses.

what is NOT a feature of cartilaginous joints?

These joints contain dense regular collagenous connective tissue; This is a feature of fibrous, not cartilaginous, joints.

________________ are fibrous joints that join articulating bones together by a long membrane called the interosseous membrane. These joints are amphiarthroses because the interosseous membrane allows for a limited amount of movement. The sutures between the skull bones are interlocked and become fused once an individual reaches skeletal maturity. This is important because they have evolved for protection of the underlying brain. If these joints were freely movable or even slightly moveable, this protective function would be compromised.
