Question

Synarthrotic joints ________.

A) are immovable joints
B) have large joint cavities
C) characterize all cartilaginous joints
D) are found only in adults

Answer 1

Synarthrotic joints are immovable joints that provide strong unions between bones for the protection of internal organs, such as sutures in the skull and synchondroses in the sternum.

Step-by-step explanation:

Synarthrotic joints are immovable joints. This classification includes joints such as sutures, which are found between the bones of the skull, and synchondroses, such as the cartilaginous joint between the manubrium and the body of the sternum. These types of joints provide protection for internal organs by creating a strong union between bones. It's important to note that not all cartilaginous joints are synarthrotic; some, like the symphysis that unites the hip bones, are classified as amphiarthroses and allow slight movement.
