A

True

20
Q

The ______ ligament joins the coracoid process of the scapula to the clavicle.

A

coracoclavicular

21
Q

The ______ ligament joins the coracoid process to the acromion of the scapula.

A

coracoacromial

22
Q

The ______ ligament surrounds the head of the humerus and anchors it to the scapula.

A

capsular(articular capsule)

23
Q

The ______ ligament connects the head of the humerus to the coracoid process of the scapula.

A

coracohumeral

24
Q

The rotator cuff tendons help to ______ so that the head of the humerus is stabilized within the joint.

A

limit the movement at the shoulder

25
Q
A

26
Q

The hip joint is a ______ joint, where the head of the femur articulates with the pelvis at the acetabulum

A

ball and socket

27
Q

Posteriorly, the pelvis is held to the sacrum by what 3 ligaments?

A
  1. iliolumbar ligament
  2. anterior sacroiliac ligament
  3. posterior sacroiliac ligament
28
Q

The______ ligament holds the ASIS of the ilium to the pubic bone.

A

ilioinguinal

29
Q

The ______ ligament attaches the femur to the ilium.

A

iliofemoral

30
Q

The ______ ligament connects the sacrum to each side of the uterus in females

A

uterosacral

31
Q
A

The pelvis and femur articulate at the hip joint. The pelvis contains many ligaments to hold it to the sacrum (posteriorly) and the internal organs.

32
Q

In the knee there are crescent-shaped pieces of cartilage called ______, which give added stability for the femur to articulate with the tibia.

A

menisci

33
Q

The ___1___ and ___2___ collateral ligaments stabilize the sides of the knee.

A
  1. medial (tibial) also known as MCL
  2. lateral (fibular) also known as LCL
34
Q

The interior of the knee joint contains the ___1___ and ___2___.

A
  1. anterior cruciate ligament (ACL)
  2. posterior cruciate ligaments (PCL)
35
Q

The knee joint also contains ___1___ fluid-filled sacs called ______, which ease friction between tendons, ligaments, and bones.

A
  1. 13
  2. bursae
36
Q

Inflammation of the bursae in a joint is called ______.

A

bursitis

37
Q
A

Anterior view of the left knee joint ligaments

38
Q
A

Posterior view of the left knee joint. ACL (blue) is the anterior cruciate ligament. The PCL is the posterior cruciate ligament.

39
Q

______ligament - connecting the anterior vertebral bodies

A

Anterior longitudinal ligament

40
Q

______ligament - connecting the posterior the vertebral bodies

A

Posterior longitudinal ligament

41
Q

______ligaments - connects the spinous process of two adjacent vertebrae

A

Interspinous ligaments

42
Q

Supraspinous ligament - connects the posterior portion of the spinous processes

A

Supraspinous ligament - connects the posterior portion of the spinous processes

43
Q

There are ______ between the vertebrae that act as a kind of padding. They prevent the vertebrae from grinding against one another and absorb shock caused by movements such as running, jumping, and even walking. The presence of the disks allows motion between the vertebrae so that we can bend forward, backward, and from side to side without the vertebrae touching.

A

intervertebral discs

44
Q

True or False: Disks tend to become weakened with age and may slip or even rupture.

A

True

45
Q

If the posterior longitudinal ligament becomes weakened, the center portion of the disc may bulge into the vertebral foramen, called a ______.

A

herniated disc

46
Q

What is a herniated dis?

A

When the posterior longitudinal ligament becomes weakened, the center portion of the disc may bulge into the vertebral foramen

47
Q
A

Posterior view of the components of a typical vertebra. Note the ligaments along the anterior, lateral, and posterior sides of the vertebral column.
