What are some examples of uniaxial joints?
A joint is a place where bones and cartilage come together to form a connection.Joints are classified into two categories.Structural classifications of joints take into account whether the adjacent bones articulate with each other within a fluid-filled space called a joint cavity or whether they are anchored by the same tissue.The degree of movement between the bones is described in functional classifications.Functional requirements for a particular joint are related to the amount of movement available at that joint.Joints that are immobile serve to protect internal organs, give stability to the body, and allow for limited body movement.Freely moveable joints allow for more extensive movements of the body and limbs.
The structural classification of joints is based on the relationship between the bones and the fluid-filled joint.The joints of the body are divided into three structural classifications.The bones are united by the same tissue.The bones are joined at a cartilaginous joint.The bones come into contact with each other in a joint that is filled with a lubricating fluid.The most common joints of the body are the synovial joints.
The amount of mobility between the bones determines the functional classification of joints.Joints are classified into three categories: synarthrosis or immobile joint, an amphiparasis, or slightly moveable joint.Depending on the location of the joint, it may be classified as a synarthrosis or an amphiarthros.A cartilaginous joint can be classified as either a synarthrosis or an amphoid joint.The synovial joints are classified as a diarthrosis joint.
A synarthrosis is an immobile joint.The strong union between the bones is provided by the immobile nature of these joints.The bones provide protection for internal organs.The manubrium and body of the sternum are connected by a cartilaginous joint that protects the heart.
Figure 1.The Skull has Suture Joints.A synarthrosis is a joint that is immobile or essentially immobile.
Figure 2.There is an intervertebral disc.The bodies of adjacent vertebrae are united by an intervertebral disc.The amphiarthrosis type of joint is formed by the limited movement between the vertebrae.Intervertebral discs are a type of cartilaginous joint.
A joint with limited mobility is called an amphiarthrosis.The cartilaginous joint is an example of this type of joint.An intervertebral disc is a thick pad of fibrocartilage.The intervertebral discs allow for a limited amount of movement between them.Large ranges of body movements can be provided by the small movements between adjacent vertebrae.
The pubic symphysis is an example of an amphiarthrosis.The pubic regions of the right and left hip bones are anchored to each other by fibrocartilage.This joint doesn't have a lot of mobility.The strength of the pubic symphysis is important.
