Skeletal Articulations (Joints) - 9

Question 1

Movement of the skeleton is possible

Answer 1

joints/articulations

Question 2

joint

Answer 2

formed where two or more bones meet and articulate with each other

Question 3

ligament

Answer 3

strong bands of dense regular connective tissue that connect bones to other bones. This holds the bones in alignment and stabilizes the joint.

Question 4

three types of joints found in the body (functional)

Answer 4

synarthroses, amphiarthroses, and diarthroses

Question 5

synarthroses

Answer 5

immovable joints

Question 6

Amphiarthroses

Answer 6

limited degree of movement

Question 7

Diarthroses

Answer 7

freely moving

Question 8

Structural Classification
of joints

Answer 8

Fibrous Cartilaginous Synovial joints

Question 9

Fibrous joints

Answer 9

formed when the articulating bones are joined by fibrous connective tissue, and there is no joint cavity or synovial cavity.

Question 10

Cartilaginous joints

Answer 10

have cartilage between the articulating bones but there is no joint cavity (synovial cavity).

Question 11

Synovial joints

Answer 11

have a synovial cavity and the articulating bones are held in alignment by a dense irregular connective tissue joint capsule and dense regular connective tissue ligaments.

Question 12

sutures

Answer 12

found in the skull early and fetal childhood
fibrous and synarthroses

Question 13

gomphoses

Answer 13

found in jaw
fibrous and synarthroses

Question 14

Syndesmoses

Answer 14

radius and ulna in the fore arm and between the tibia and fibula in the lower leg
fibrous and amphiarthrotic

Question 15

Synchondroses

Answer 15

long bones involve an epiphysial plate, which is made up of hyaline cartilage and connects the epiphysis with the diaphysis of the long bone
cartilaginous

Question 16

symphysis

Answer 16

When two similar bones are joined by fibrocartilage

Question 17

Synovial Joint

Answer 17

most common type of joint in the body

Question 18

Bursa

Answer 18

sac filled with synovial fluid and provides a cushion between bones and tendons and/or muscles around a joint
reduce friction and allow free movement

Question 19

tendon sheath

Answer 19

protective covering.

Question 20

Classification of Diarthrotic Joints

Answer 20

uniaxial, biaxial, multiaxial and synovial

Question 21

uniaxial joints

Answer 21

allow movement in only one body plane
plane/ gliding - carpals and tarsals
hinge - present in elbow and knee
pivot -side to side rotation

Question 22

biaxial joints

Answer 22

Condyloid or condylar joint between the metacarpals and phalanges, and between metatarsals and phalanges.

Saddle joint is present between the trapezium and the 1st metacarpal.

Question 23

multiaxial joints

Answer 23

Ball-and-Socket joints,

Question 24

synovial joints

Answer 24

shoulder and hip
elbow and knee

Question 25

Inflammation of the fluid-filled pads (bursae) that act as cushions at the joints.

Answer 25

bursitis

Question 26

degenerative joint disease, commonly known as “wear-and tear” arthritis. There is deterioration of articular cartilage and bone spur formation. It is non-inflammatory, and primarily affects weight-bearing joints, lumbar spine etc

Answer 26

Osteoarthritis

Question 27

caused by deposition of sodium urate crystals in soft tissues. It cause inflammation, swelling, and pain, and if not treated, bones at affected joints eventually fuse together. It is more common in males. Anti-inflammatory medications are helpful.

Answer 27

gouty arthritis

Question 28

autoimmune disease, which affects people 40-50 yrs of age. There is inflammation of the synovial membrane, and it may result in ankylosis, in which stiffness causes fingers to deform. There may be swelling, pain, and loss of function. Medications like aspirin, antibiotic can be helpful.

Answer 28

Rheumatoid arthritis

Question 29

inflammation of tendon

Answer 29

tendonitis

Question 30

inflammation of joints

Answer 30

arthriitis
