IOS251 Week 7 Lab Exercise
To complete this worksheet, select:
Module: Support and Movement Activity: Anatomy Overviews Title: Joints
1. a From the main Joints page, click Fibrous Joints and identify each of the following structural joint types.
Suture: A type of fibrous Interlocking joints in the skull.
Syndesmoses: An immovable joint in which bones are joined by connective tissue.
Gomphosis: A joint that binds the teeth to bony sockets in the maxillary bone and mandible.
b. Why are sutures and Gomphosis classified as synarthroses?
These sutures are fibrous joints that are immovable.
c. Syndesmoses are functionally a bit different. They are classified as amphiarthroses. Explain why.
This is because they allow slight movement.
2. a. Return to the main Joints page and click Cartilaginous Joints. Identify each of the following.
Synchondrosis: This is a joint that is connected with cartilage; they are stiff and very strong.
Symphysis: This is a fibrocartilaginous fusion between two bones.
b. Describe the role of hyaline and fibrocartilage in each of these types of joints.
In Synchondrosis: Hyaline cartilage connects the bones in this type of joint.
In Symphysis: This type of joint is somewhat movable. It is made of fibrocartilage coated in hyaline cartilage.
3. a. Once again, from the main Joints page, click Synovial Joints and identify each of the following:
Articulating bones - These describe the joints of the bones.
Periosteum - this is a dense lyre of the vascular connective tissue enveloping the bones except at the surfaces of the joints.
Articular cartilage - this a smooth surface at the ends of two bones basically made of hyaline cartilage, but contains more water.
Ligament - Connect bone to bone and provide strength and reinforcement for the joint.
Articular capsule - is an envelope surrounding a synovial joint.
Fibrous capsule is an envelope surrounding a synovial joint
