Answer to Problem 1MC
Solution:
| Description | Key |
| Exhibit a joint cavity | Synovial joint |
| Types are sutures and syndesmoses | Fibrous joint |
| Bones are connected by collagen fibers | Fibrous joint |

| All are diarthrotic | Synovial joint |
| Many are amphiarthrotic | Cartilaginous joints |
| Bones are connected by a disc of hyaline cartilage or fibrocartilage | Cartilaginous joints |
| Nearly all are synarthrotic | Fibrous joint |
| Shoulder, hip, jaw, and elbow joints | Synovial joint |
Explanation of Solution
A synovial joint consists of a cavity. It is made up of dense and irregular connective tissue and forms the articular capsule. The capsule is linked with the accessory ligaments. The ends of the joint bones are surrounded by a smooth glass-like hyaline cartilage.
The fibrous joints are sutures, gomophoses, and syndesmoses. Suture is narrow and joins most of the bones of the skull together. Syndesmosis is a slightly movable joint where bones are joined together by a connective tissue.
The fibrous joints are attached to each other by a connective tissue. This tissue consists of collagen fibers. The fibrous joint has three types, namely, suture, gomphosis, and syndesmoses.
The cartilaginous joints are attached to each other by a cartilage. It allows more movement between two bones as compared to the fibrous joint. The primary cartilaginous joints are known as synchondroses and the secondary cartilaginous joint is symphysis.
The synovial joint is known to be diarthrotic. It joins with the fibrous joint capsule that is continuous with the periosteum of the fixed bones. It consists of an outer boundary of synovial cavity.
Amphiarthrosis is a kind of continuous and slightly movable joint. The contiguous bony surface can be symphysis that is connected by broadly flattened discs and an interosseous membrane. It is seen in cartilaginous joints.
The cartilaginous joint involves the fibrocartilage or the hyaline cartilage. The joints are slightly movable, that is, they are amphiarthrotic. They are connected by cartilage and allow the movement of bones.
The fibrous joints can be synarthrotic or amphiarthrotic. The sutures are synarthrotic joints and are situated between the bones of the skull. The edges of the bones are interlocked and they are bound together at suture.
The hip, shoulder, and jaw consist of a synovial joint. A synovial joint consists of a cavity. It is made up of dense and irregular connective tissue and forms the articular capsule.

Can you tell…arrow_forwardYou have been hired as a public relations specialist to give invertebrates a good name. After all, they are much more than just creepy crawly bugs! Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forward
