78. Posterior cruciate ligament

Question 11

capsular ligament

Answer 11

surrounds the head of the humerus and anchors it to the scapula

Question 12

80. This ligament connects the anterior vertebral bodies.

Answer 12

80. Anterior longitudinal ligament.

Question 13

82. Why can a herniated disc be painful?

Answer 13

82. Pain results when the damaged disk presses against the spinal cord or the spinal nerves.

Question 14

What is an example of a fibrous joint?

Answer 14

between cranial bones

Question 15

What is an example of a cartilaginous joint? What is its level of movement?

Answer 15

joints between vertebrae and slightly moveable

Question 16

Describe the joint of the pelvic bones?

Answer 16

slightly movable, anteriorly joined by fibrous cartilage, the pubic symphysis. hormonal changes during late pregnancy, make joint more flexible, allowing the pelvis to expand during childbirth

Question 17

What are most joints classified as? What is there level of movement?

Answer 17

synovial joints and they are freely moveable

Question 18

Ligaments

Answer 18

composed of fibrous connective tissue, bind the bones together

Question 19

joint capsule

Answer 19

outer layer forms ligament and inner synovial cavity has synovial membrane awhich produces synovial fluid

Question 20

What are the different types of synovial joints?

Answer 20

ball-and-socket, hinge, saddle, and pivot joints

Question 21

hinge joint

Answer 21

the knee and elbow joints, which largely permit movement in one direction only

Question 22

ball-and-socket joint

Answer 22

all movement in all planes, rotational movement, examples are the hip and shoulder joints

Question 23

saddle joint

Answer 23

in thumb, allows it tho freely cross over palm

Question 24

pivot joint

Answer 24

allows for rotational movement, example are C1 and C2 vertebrae

Question 25

How is a ligament most often named?

Answer 25

for the 2 bone landmarks they connect

Question 26

What connects the head of the humerus to the coracoid process of the scapula?

Answer 26

coracohumeral ligament

Question 27

What muscles form the rotator cuff?

Answer 27

supraspinatus, infraspinatus, teres minor, and subscapularis

Question 28

What is the function of the rotator cuff?

Answer 28

limit the movement at the shoulder so head of humerus is stabilized within the joint.

Question 29

What holds the ASIS to the pubic bone?

Answer 29

ilioinguinal ligament

Question 30

What connects the scrum to each side of the uterus in women?

Answer 30

uterosacral ligament

What ligaments posteriorly hold the sacrum to the pelvis?

Answer 31

iliolumbar ligament, anterior sacroiliac ligament and posterior sacroiliac ligament

Question 32

menisci

Answer 32

crescent-shaped pieces of cartilage, which give added stability for the femur to articulate with the tibia

Question 33

What stabilzes the front of the knee?

Answer 33

patellar ligament

Question 34

What stabilizes the sides of the knee?

Answer 34

MCL(medial colateral ligament) and LCL(lateral colateral ligament)

Question 35

What internally stabilizes the knee joint?

Answer 35

ACL(anterior cruciate ligament) and PCL(posterior cruciate ligament)

Question 36

bursae

Answer 36

13 fluid-filled sacs in the knee joint, which ease friction between tendons, ligaments, and bones

Question 37

what is inflammation of the bursae called?

Answer 37

bursitis

Question 38

What conncects the posterior vertebral bodies?

Answer 38

posterior longitudinal ligament

Question 39

What connects the spinous process of 2 adjacent vertebae?

Answer 39

interspinous ligaments

Question 40

What connects the posterior portion of the spinous processes?

Answer 40

supraspinous ligament

Question 41

What is the function of the intervertebral discs?

Answer 41

prevent the vertebrae from grinding against one another, absorb shock, allows motion e.i. bending forward, backward, and side to side without the vertebrae touching.

Question 42

herniated disc

Answer 42

if posterior longitudinal ligament becomes weakened disc bulges and presses into vertebral foramen onto the spinal cord and nerves
