In rheumatoid arthritis

the synovial membrane becomes inflamed and thickens, forming a mass.

In rheumatoid arthritis Select one: synchondrosis joints are affected exclusively. only older adults are affected, as growing joints are not affected. joints separate and ligaments become extremely loose as they break down. the synovial membrane becomes inflamed and thickens, forming a mass. Clear my choice

the synovial membrane becomes inflamed and thickens, forming a mass.

The intermediate radioulnar joint exists between the radius and the ulna. The two bones are joined together by a high-collagen sheet of dense connective tissue. This joint allows slight movements and flexibility between the two bones. What specific type of joint is this?

A fibrous syndesmotic joint

Which of the following correctly pairs a term with its definition?

Abduction—lifting the arm out to the side of the body so that it is parallel to the ground

Flexion of the Hip joint causes the cural to move Select one: Lateral Anterior Posterior Medial

Anterior

Flexion of the shoulder joint causes the brachium to move: Select one: Posteriorly Anteriorly Laterally Medially

Ball-and-socket joint

Suppose all synarthrotic joints were fused in an individual. Which of the following would be true of this individual?

Braces would not work to straighten the person's teeth because their teeth would not move.

Suppose the pubic symphysis did not exist in the pelvic girdle and the two pubic bones were fused in the middle. Which of the following best describes the way the region would be affected if this joint was removed?

Childbirth would have a high mortality risk because the pelvic girdle would be rigid and unmoving.

Joints can be classified as synarthrotic, amphiarthrotic, or diarthrotic. What characteristic was used to classify the joints?

Degree of movement possible at the joint

A ball-and-socket joint is also called an ellipsoidal joint.

False

The act of closing the fingers to make a fist is an example of what type of joint movement (at the interphalangeal joints)? Select one: Extension Flexion Abduction Rotation

Flexion

A football player suffers from a partially torn anterior cruciate ligament. Which joint has been injured?

Knee

A person works an office job that requires them to be in a sitting position for 10 hours a day. They go home and sit until they go to bed. This person never exercises and rarely gets up to move around after being seated. Their joints begin to constantly feel stiff and painful. On a physiological level, what has happened to cause these symptoms?

Lack of movement hinders blood from moving through the vessels of the synovial membrane, which starves the ligaments of nutrients and causes them to lose elasticity.

Adduction of the hip joint causes the tarsals to move Select one: Inferior Lateral Medial Superior

Medial

Extension of the Hip joint causes the femur to move: Select one: Medial Posterior Anterior Lateral

Posterior

The ball-and-socket joint of the hip is replaced with a pivot joint in which the femur is directly planted into the acetabulum. What movement(s) is/are now the only one(s) possible?

Rotation

The ball-and-socket joint of the hip is replaced with a pivot joint in which the femur is directly planted into the acetabulum. What movement(s) is/are now the only one(s) possible? Select one: Rotation Flexion and extension Abduction and adduction Circumduction

Rotation

You turn your head to look at something. What type of joint movement is this?

You turn your head to look at something. What type of joint movement is this? Select one: Circumduction Retraction Rotation Abduction

Rotation

An athlete, after years of pitching, requires surgery to repair his glenohumeral ligaments. Which joint has been injured?

Shoulder
