Answer 13

serves to connect the clavicle and the coracoid process of the scapula.

Question 14

coracohumeral ligament

Answer 14

The coracohumeral ligament is a fibrous structure that contributes to the stability of the glenohumeral joint by combined action with the rotator cuff muscles, superior glenohumeral ligament, and capsule

Question 15

glenohumeral ligament

Answer 15

these three ligaments combine to form the glenohumeral joint capsule connecting the glenoid fossa to the humerus.

Question 16

Elbow Joint (humeroulnar +

Answer 16

The humeroulnar and the humeroradial joints are the joints that give the elbow its characteristic hinge like properties

Question 17

Shoulder Joint (glenohumeral)

Answer 17

a true synovial ball-and-socket style diarthrodial joint that is responsible for connecting the upper extremity to the trunk.

Question 18

articular capsule

Answer 18

an envelope surrounding a synovial joint

Question 19

ulnar collateral ligament

Answer 19

a ligament that runs on the inner side of the elbow to help support it when performing certain motions, such as throwing.

Question 20

radioulnar joint (proximal, distal)

Answer 20

The radioulnar joints are two joints between the two bones of the forearm: the ulna, on the medial side, and the radius, on the lateral side.

Question 21

radiocarpal articulation

Answer 21

The radiocarpal joint is a synovial joint formed by the articulation between the distal radius and the scaphoid, lunate, and triquetrum as well as the soft tissue structures that hold the joint together.

Question 22

intercarpal joint

Answer 22

Intercarpal joints are all classified as synovial plane joints, meaning that the articular surfaces are functionally considered as nearly flat and lined with fibrocartilage.

Question 23

carpometacarpal joint

Answer 23

The base of the thumb where it meets the hand

Question 24

metacarpalphalangeal joint

Answer 24

the large joint in the hand where the finger bones meet the hand bones

Question 25

interphalangeal joint (proximal, distal)

Answer 25

The proximal interphalangeal joint (PIPJ or PIJ) is located between the proximal and middle phalanges, while the distal interphalangeal joint (DIPJ or DIJ) is found between the middle and distal phalanges.

Question 26

sacroiliac joint

Answer 26

The sacroiliac joint or SI joint (SIJ) is the joint between the sacrum and the ilium bones of the pelvis, which are connected by strong ligaments.

Question 27

pubic symphysis

Answer 27

a joint sandwiched between your left pelvic bone and your right pelvic bone

Question 28

sacrococcygeal joint

Answer 28

an amphiarthrodial joint, formed between the oval surface at the apex of the sacrum, and the base of the coccyx

Question 29

ischiofemoral ligament

Answer 29

attaches to the posterior surface of the acetabular rim and labrum and courses circumferentially around the joint to its insertion on the anterior aspect of the femur.

Question 30

iliofemoral ligament

Answer 30

the strongest and most important hip capsular ligament

Question 31

pubofemoral ligament

Answer 31

Located on the anterior aspect of the hip joint, this ligament extends from the anterior portion of the pubic ramus to the anterior surface of the intertrochanteric fossa often blending with the inferior fibers of the iliofemoral ligament.

Question 32

acetabulofemoral joint (hip joint)

Answer 32

Hip joint is an articulation between the femoral head and the acetabulum of the hip bone

Question 33

tibiofibular joint (proximal, distal)

Answer 33

The superior (proximal) tibiofibular joint - between the superior ends of tibia and fibula. The inferior (distal) tibiofibular joint - between their inferior ends.

Question 34

tibial collateral ligament

Answer 34

superficial medial collateral ligament. It is about eight to ten centimeters long and stretches from femur's medial epicondyle (a bony protrusion at the bottom, inner-side of the bone) to the two attachments on the tibia bone.

Question 35

fibular collateral ligament

Answer 35

The fibular collateral ligament (FCL) is one of the larger ligaments of the knee.

Question 36

medial meniscus

Answer 36

a crescent-shaped, cartilaginous band found between the medial tibia and medial femur.

Question 37

lateral meniscus

Answer 37

located on the outer side of the knee. Both structures act as shock absorbers between the femur (thigh bone) and the tibia (shin bone). The lateral meniscus is more oval than the medical meniscus and is larger, thus covering more surface space than the medial meniscus.

Question 38

patellar ligament

Answer 38

When a structure connects one bone to another, it is actually a ligament, so the patellar tendon is sometimes called the patellar ligament.

Question 39

anterior cruciate ligament

Answer 39

one of the key ligaments that help stabilize the knee joint.

Question 40

posterior cruciate ligament

Answer 40

The posterior cruciate ligament (PCL) is the strongest ligament in the knee. It extends from the top-rear surface of the tibia

Question 41

talocrural joint

Answer 41

formed between the distal tibia-fibula and the talus, and is commonly known as the ankle joint.

Question 42

intertarsal joint

Answer 42

The joints between the tarsal bones of the foot are known as the intertarsal joints

Question 43

tarsometatarsal joint

Answer 43

The tarsometatarsal joints are composed of the articulations between the bases of the metatarsals and the distal surfaces of the three cuneiforms and the cuboid

Question 44

metatarsalphalangeal joint

Answer 44

ellipsoid synovial joints that lie about 2 cm proximal to the webs of the toes.

Question 45

interphalangeal joint (proximal, distal)

Answer 45

The proximal interphalangeal joint (PIPJ or PIJ) is located between the proximal and middle phalanges, while the distal interphalangeal joint (DIPJ or DIJ) is found between the middle and distal phalanges.
