Question

1 Would fibrous and cartilaginous joints be able to perform their functions if t 2 Your father plans to visit an alternative medicine practitioner for "cranial therapy." You read the brochure for this proposed treatment and note that it involves the movement and manipulation of the cranial sutures, which the practitioner claims will cure nearly all diseases. What kind of joint is a cranial suture, both structurally and functionally? Given these facts, what do you think of the claims made about “cranial therapy?"

Explanation / Answer

1. Even if the fibrous and the cartilagenous joints have join cavities much movement wouldn't be possible because of the fact that in the fibrous joint there is fibrous tissue in the joint space that wouldn't allow much movement and in the cartilagenous joint there is a thick pad of fibrocartilage in addition to the end of the bones covered with hyaline cartilage.

2.Cranial sutures are fibrous joints and functionally it's a synarthrosis which allows very little or no movement.
