Because it is an immovable joint, the sagittal suture, which joins the two parietal bones of the skull, is classified as a _______.
Most of the freely movable joints of the body could be classified both structurally and functionally as __________.
synovial and diarthroses
A gomphosis is which type of joint?
fibrous and a syndesmosis
The bodies of adjacent vertebrae are connected by pads of fibrocartilage (the intervertebral discs). The articulations between adjacent vertebrae are called __________.
Some synovial joints contain special crescent-shaped pads that provide additional shock absorption, and provide for a better fit between the articulating surfaces of the bones. These special pads are called __________.
Which of the following is not a function of synovial fluid?
to maintain a sterile environment within the joint cavity
A body builder is doing curls, a type of arm exercise, with hand weights. In a curl, the body builder bends his arm and brings the weight closer to his or her shoulder. What type of movement is this?
Which of the following is a type of angular movement?
--all of these are examples of angular movement
all of these
A child has learned how to draw circles in the air by moving the distal end of the index (pointing) finger while holding the rest of his hand still. What type of movement is this?
The image below is demonstrating a type of movement at the wrist. This movement could be seen in the waving gesture made by a beauty queen on a parade float, or by a real queen, such as Her Majesty Elizabeth II waving from the balcony at Buckingham Palace. What type of movement is this?
A common facial expression which indicates shock or surprise is when one's mouth drops open. The chin drops and the mouth opens wide. What type of movement is this (hint: it occurs at the temporomandibular joint)?
The radioulnar joint allows a person to turn their hands so that the palms face anteriorly (as in anatomical position) or to face posteriorly. The radioulnar joint is an example of what type of synovial joint?
Which of the following is an example of a uniaxial joint?
the hinge joint of the elbow
Which type of joint confers the greatest range of motion?
This joint is the largest and most complex of the body, and consists of three joints contained within its synovial cavity.
Symphyses are a type of cartilaginous joint. All symphyses occur at the midline of the body, and not in the extremities.
The fibrous capsule of a synovial joint is a thickened continuation of the periosteum of the bones that articulate at the joint.
Tendon sheaths are similar to bursae in structure, but wrap tendons in areas where they receive a great deal of frictional wear and tear, such as the wrists and ankles, and where tendons pass through synovial cavities.
The joint between the atlas and axis vertebrae is an example of a pivot joint.
Ball-and-socket joints are triaxial (multiaxial), because they allow motion around three axes (flexion -extension, abduction -adduction, and rotation).
A synarthrosis is a freely movable joint.
In which of the following types of joints are the bones that are held together by cartilage, with no synovial cavity?
A fibrous joint in which there is a greater distance between the articulating surfaces and more dense irregular connective tissue than in a suture is called a
Adduction is the movement of bone away from the midline; abduction is movement of a bone toward the midline.
Shoulder and hip joints are examples of which type of synovial joint?
Which factors help to keep the articular surfaces in contact and affect the range of motion?
--structure or shape of articular bones
--strength and tension (tautness) of the joint ligaments
--arrangement and tension of the muscles
--contact of soft parts
--all of these choices
all of these choices
The fluid in bursae is similar to synovial fluid.
Synovial joints are classified as diarthrotic joints because the presence of the synovial cavity allows a large amount of movement at the joint.
