Describe the movement of gliding joints (plane joints).

as the body moves, the vertebrae of the spine move against each other as gliding joints

The hip and shoulder joints are examples of the ___ joints.

ball and socket

A synchrondosis is a non-moving ___ joint.

cartilaginous

What are the 6 types of synovial joints?

gliding (plane), hinge, pivot, condyloid, saddle, ball and socket

The fibrous articulations between the teeth and the mandible (or maxilla) are non-moving joints called ___.

gomphoses

The major ___ joints include the intervertebral joints and the bones of the wrists (carpal joints) and ankles (tarsal joints).

gliding (plane)

The major ___ joints in the skeleton include the elbow and the finger joints

hinge

The joint located at the top of the spine between the axis (C02) and the atlas (C01) is called the ___ joint.

pivot

The ball and socket joint can ___ on axis/plane

rotate

These joints have serrated edges that lock together with fibers of connective tissue.

sutures

The joint between the first pair of ribs and the sternum is an example of a ___ joint.

synchrondosis

Joints with slight movement are called ___.

syndesmoses

What type of joint contains a ligament connecting two bones, allowing for a little movement?

syndesmoses

Joints with full movement are called ___.

synovial

Ligaments reinforce ___ joints and limit movement to prevent injury (i.e. the knee)

synovial

What type of joint contains the fibrocartilaginous pad connecting two bones, allowing for little movement?

symphyses

Non-moving joints are called ___.

synarthroses

The distal joint between the tibia and fibula are an example of which type of joint?

syndesmoses (little movement)

Synovial joints are characterized by the presence of an ___ located between the two joined bones, often supported by surrounding ligaments.

articular capsule

True or False: All skull joints are sutures.

false; all except for the skull joint connecting the mandible to the temporal bone.

True or False: Sutures are not fracture-resistant.

false; the interlocking edges make sutures strong and fracture-resistant.

Joints throughout the body hold the skeleton together and support ___ .

movement

Describe the movement of hinge joints.

only moves in one plane/axis (i.e. the elbow)

Describe the movement of the pivot joints

rotation; of the head

The ___ joint is located between the first metacarpal (thumb) and the trapezium

saddle

Bone surfaces at the synovial joint are protected by a coating of ___.

articular cartilage

The ___ joint allows for circumduction, flexion, and extension movements of the wrist (carpal)

condyloid

The ___ joint is located between the radius and wrist (carpal bones)

condyloid

The skull sutures are an example of which type of joint?

fibrous; non-moving (synarthroses)

Define the saddle joints

resemble condyloid joints but they allow greater freedom of movement, has both convave and convex areas, shaped like a saddle (i.e. thumb)

True or False: Articular cartilage located at the joints degenerate with age and wear

true
