1

Fibers

Skeletal muscle contains long organized units called muscle ______.

2

Muscle

The characteristic long fibers are under voluntary control, allowing us to contract a(n) ______ and move a joint.

3

Multipennate, circumpennate

A(n) _____ muscle has a division of several feather-like sections in one muscle, and the ____ is the convergence of fibers to a central tendon.

4

Tendon

The attachment of the muscle that occurs at the proximal and distal portion of the bundle is called a(n)______.

5

Synovial

Tendons occur with or without a(n) _____ sheath.

6

Shoulder, hand, wrist, ankle

The sheath surrounding a tendon has two layers. The fluid separates the layers in this part of the body: _____, ______, _____, and ______.

7

Ligaments

Short bands of tough fibers that connect bones to other bones are _____.

8

Bursa

The saclike structure surrounding joints and tendons that contains a viscous fluid is the _____.

9

Nine

The knee joint has _____ bursa.

10

Paratenon

A loose areolar connective tissue that fills the facial compartment of the tendon lacking a synovial sheath is a(n) _____.

11

Epitendineum

The dense ______ is another layer of connective tissue that closely adjoins the tendon.

12

Parallel

Interwoven an interconnected collagen fibers found in the tendon run in a(n) ______ path.

13

Origin, insertion

The proximal portion of the muscle is considered the ______, whereas the ______ is the distal end.

14

Hyperechoic, hypoechoic

The normal nerve has a(n) ______ appearance when compared with muscle, but it is _____ to tendons.

15

Friction

The minute amount of viscous fluid contained within the bursa helps reduce _____ between the moving parts of the joint.

16

Communicating

A Baker's cyst is an example of a(n) ______ bursa in the medial popliteal fossa.

17

Internal

To begin the examination of the biceps, place the patient with a slight _____ rotation of the shoulder.

18

Left, right

When facing the patient and imaging the right shoulder, the lateral anatomy displays on the _____ side of the image and the medial anatomy on the ____ side of the screen.

19

Biceps

The groove located between the greater and lesser tuberosities, coupled with the overlying transverse ligament, maintains the _____ tendon location.

20

Anteromedially

Using the biceps tendon as a landmark, angle the transducer ______ to locate the subcapsularis tendon.

21

Supraspinatus

The bandlike tendon that has a medium level echotexture is the ______ tendon and originates from the greater tuberosity of the humerus.

22

Glenoid labrum

A good landmark to help find the anteriorly located infraspinatus tendon is the posterior ______.

23

Superficial, posterior

Fluid imaged _____ to the infraspinatus tendon indicates bursal fluid, whereas _____ fluid indicates joint effusion.

24

Carpal, flexor

The carpal tunnel is located between the ____ bones and the ____ retinaculum on the palmar side of the wrist.

25

Radial

The ulnar artery and vein indicate the medial border of the carpal tunnel, where as the most lateral structure is the ____ artery and veins.

26

Achilles

The tendon that connects the gastrocnemius and soleus muscle to the calcaneus is the _____ tendon.

27

Transverse humeral ligament, abnormal development of bicipital groove, supraspinatus and/or subcapsularis tears

The dislocation of the biceps tendon from the bicipital groove maybe due to a problem with:

28

Partial

The _____ thickness tear involves either the bursal or articular cuff surface on the intrasubstance material.

29

Full-thickness

The presence of large amounts of fluid in the subacromial-subdeltoid bursa raises the chance of a non-visualized _____ tear.

30

Flattens

The normal tendon cannot be compressed; however, the injured tendon ____ as the torn edges move apart.

31

Double-effusion

Joint effusion around the biceps tendon combined with subacromial-subdeltoid bursitis results in the _____ sign.

32

Synovial

Acute tendinitis involves not only the tendon but the surrounding ____ sheath.

33

Halo

The normal synovial sheath appears as a hypoechoic _____ around the tendon.

34

Distraction

The abrupt stretching of the muscle beyond the maximum length results in a(n) _____ tear.

35

Compression

External force resulting in a crush injury is considered a(n) ______ tear.
