Question | Answer |
---|---|
What is the most mobile joint in the body? | Glenohumeral |
Literally meaning “inflammation of the joint,” what is the name of the most common type of joint disorder? | Arthritis |
What is a slightly movable joint that connects bone to bone with fibrocartilage or hyaline growth cartilage called? | Amphiarthrosis |
What is the movement of the bone surface in the joint capsule, including roll, spin, and slide called? | Arthrokinematics |
When two or more bones meet to connect parts and allow for movement in the body it is called a(n): | articulation. |
Which of the following joints allows movement in many directions around a central point? | Ball-and-socket joint |
What is the term for a flat sac of synovial membrane in which the inner sides of the sac are separated by fluid film? | Bursa |
Hyaline, fibrous, and elastic are all types of: | cartilage. |
The positioning of joints in such a way that motion at one of the joints is accompanied by motion at an adjacent joint is called what type of chain? | Closed kinematic |
The only position of a synovial joint in which the surfaces fit precisely together and maximum contact between the opposing surfaces occurs is in what type of position? | Closed-packed position |
Movement in two directions, but with one motion predominating, is performed by what type of joint? | Condyloid |
What is the term for a freely movable synovial joint? | Diarthrosis |
Which of the following types of connective tissue fiber has elastic properties and allows flexibility of connective tissue structures? | Elastin |
Which of the following is a connective tissue that permits little motion in joints and structures, is found in places such as the intervertebral disks, and forms the ears? | Fibrocartilage |
An articulation in which fibrous tissue connects bone directly to bone is what type of joint? | Fibrous |
What are cystic, round, usually nontender swellings located along tendon sheaths or joint capsules called? | Ganglion |
Which of the following joints allows only a sliding motion in various planes? | Gliding |
Which of the following joints allows flexion and extension in one direction, changing the angle of the bones at the joint? | Hinge |
The thin covering of articular connective tissue on the ends of the bones in freely movable joints in the adult skeleton is what type of cartilage? | Hyaline |
A range of motion of a joint greater than what would be permitted normally by the structure and results in instability is called: | hypermobility |
What is the range of motion of a joint less than what would be permitted normally by the structure called? | Hypomobility |
Involuntary movement that occurs between articular surfaces, is separate from the range of motion of a joint produced by muscles, and must occur for normal functioning of the joint is called joint: | play. |
Which of the following describes a synovial joint in which the joint capsule is the most lax? | Loose-packed position |
In which of the following are the ends of the limbs or parts of the body free to move without causing motion at another joint? | Open kinematic chain |
When connective tissue is permanently deformed and is unable to return to its original state, what range is it said to be in? | Plastic |
A bony projection from one bone that fits into a “ring” formed by another bone and ligament structure to allow rotation around its own axis describes what type of joint? | Pivot |
What is another name for adduction of the spine? | Lateral flexion |
Convex in one plane and concave in the other, with the surfaces fitting together, describes what type of joint? | Saddle |
A synarthrotic joint in which two bony components are united by a thin layer of dense fibrous tissue is what type of joint? | Suture |
Two bony components that are joined directly by fibrocartilage in the form of a disk or plate is called a: | symphysis |
What is a limited-movement, nonsynovial joint called? | Synarthrosis |
A joint in which the material used for connecting the two components is hyaline cartilage is called a: | synchondrosis |
A fibrous joint in which two bony components are joined directly by a ligament, cord, or aponeurotic membrane is a: | syndesmosis. |
The thick, colorless, lubricating fluid secreted by the joint cavity membrane is: | synovial fluid. |
A freely moving joint that allows motion in one or more planes of action is a: | synovial joint. |
Which of the following forces has the potential for the most serious joint injury? | Torsion |
Which of the following is an immune-related type of inflammatory joint disease? | Rheumatoid arthritis |
Internal rotation is known as what other type of rotation? | Medial |
The acromioclavicular joint is formed between the clavicle and the: | scapula. |
What kind of joint is the glenohumeral joint? | Ball-and-socket |
The radioulnar joint provides which of the following movements? | Pronation and supination |
What joints connect the pelvis to the trunk? | Sacroiliac and symphysis pubis |
What bones articulate at the knee? | Patella, tibia, and femur |
What is the most mobile joint in the body? | Glenohumeral |
