Answer 1

Fibrous joints provide stable connections between bones with little to no movement, such as sutures in the skull, syndesmoses in the limbs, and gomphoses that anchor teeth.

Step-by-step explanation:

The main function of a fibrous joint is to provide a stable connection between bones, allowing for little to no movement. Fibrous joints, such as sutures, syndesmoses, and gomphoses, are held together by fibrous connective tissue. For example, sutures are found in the skull where they connect bones with short fibers to unit them tightly, serving to protect the brain. In syndesmoses, bones are connected with ligaments or membranes, allowing for slight movements, which can be found in the forearm and lower leg. Gomphoses, like those that anchor teeth in the jaw, allow for very minor movement under stress, such as chewing.

Answer 2

In a fibrous joint the bones which are adjacent to each other are connected by fibrous connective tissues, mainly collagen, with out forming any cavity of joint.

Step-by-step explanation:

• The fibrous joints and not movable and cover important structures like brain being covered by skull bones which are articulated by fibrous joints namely sutures.
• Long bones too are stabilized by this type fibrous joints as is formed between radius and ulnar bone of forearm.
• Another important fibrous joint is in between the root of the teeth and gum sockets in maxillary region. Here fibrous joint binds the teeth firmly so that continuous motion and pressure during eating may not loosen it.
