Question:
The axioscapular group of muscles include which one of the following?
Supraspinatus
Trapezius Correct
Subscapularis
Pectoralis major
Explanation:
The axioscapular group attaches the trunk to the scapula and includes the trapezius, rhomboids, serratus
anterior, and levator scapulae. The scapulohumeral group of muscles extends from the scapula to the
humerus and includes the muscles inserting directly on the humerus. This group includes the
supraspinatus, infraspinatus, teres minor, and subscapularis. The axiohumeral muscle group attaches the
trunk to the humerus and includes the pectoralis major and minor, and the latissimus dorsi.
Question:
An example of a cartilaginous joint would be the:
vertebral bodies of the spine. Correct
skull.
shoulder.
knee.
Explanation:
Vertebral bodies of the spine and the pubic symphysis of the pelvis are examples of cartilaginous joints.
Examples of synovial joints include the shoulder, knee, hip, wrist, distal radioulnar, elbow, and carpals. The
skull is an example of the fibrous joint.
Question:
The part of the ulna that forms the outer prominence of the elbow is referred to as the:
olecranon bursa.
olecranon fossa.
olecranon process. Correct
olecranon.
Explanation:
The part of the ulna that forms the outer prominence of the elbow is referred to as the olecranon process.
This process fits into the fossa of the humerus when the arm is extended.
Question:
To assess muscle tone in the legs, support the patient's thigh with one hand, grasp the foot with the other,
and:
extend the patient's feet.
flex and extend the patient's knee and ankle on each side. Correct
, have the patient try to lift the foot.
feel for jerkiness in the calf.
Explanation:
To assess muscle tone in the legs, support the patient's thigh with one hand, grasp the foot with the other,
and flex and extend the patient's knee and ankle on each side noting for any resistance to the movements.
Question:
When grading muscle strength, a grade of three would indicate:
no muscular contraction detected.
barely detectable trace of contraction.
active movement of the body part with gravity eliminated.
active movement against gravity. Correct
Explanation:
A grade of three would indicate active movement against gravity. Zero muscular strength would indicate
no muscular contraction was noted on exam. A grade of one indicates a barely detectable trace of
contraction noted on exam. For active movement of the body part with gravity eliminated, a grade of two
would be noted.
Question:
Joints in which bones have intervening layers of fibrous tissue or cartilage holding the bones together are
referred to as:
cartilaginous joints.
synovial joints.
fibrous joints. Correct
extra-articular joints.
Explanation:
Fibrous joints, such as the sutures of the skull, have intervening layers of fibrous tissue or cartilage holding
the bones together. The bones are almost in direct contact and do not allow movement. Cartilaginous
joints, such as those between vertebrae and the symphysis pubis, are slightly movable. In these joints,
fibrocartilaginous discs separate the bony surfaces. Joints in which bones do not touch each other, and the
joint articulations are freely moveable (within the limits surrounding ligaments) are called synovial joints.
Extra-articular refers to the structures of selected regions of the joint and types of movement.
Question:
Passive flexion, varus stress, and external rotation of the lower leg evaluates the:
medial meniscus. Correct
lateral meniscus.
lateral collateral ligament (LCL).
posterior cruciate ligament (PCL).
Explanation:
Passive flexion, varus stress, and external rotation of the lower leg evaluates the medial meniscus.
, Question:
When examining the knee, the presence of a palpable fluid wave with the returning fluid wave into the
suprapatellar pouch is noted. This positive sign for effusion of the knee is known as the:
balloon sign. Correct
bulge sign.
balloting sign.
McMurray's sign.
Explanation:
A positive balloon sign for effusion in the knee is the presence of a palpable fluid wave with a returning
fluid wave into suprapatellar pouch. When examining the knee, a fluid wave on the medial side between
the patella and the femur is noted. This positive sign for effusion is known as the bulge sign. Balloting of
the patella is tested by compressing the suprapatellar pouch and pushing the patella sharply against the
femur. If fluid returns to the suprapatellar pouch, then an effusion of the knee is diagnosed. McMurray's
test checks for tears in the medial meniscus.
Question:
The Abduction (or Valgus) Stress Test is a maneuver used to assess the function of the:
Achilles tendon.
medial meniscus.
medial collateral ligament (MCL). Correct
lateral collateral ligament (LCL).
Explanation:
The Abduction (or Valgus) Stress Test is a maneuver that evaluates the function of the medial collateral
ligament. To perform this test, place the knee in thirty degrees of flexion. While stabilizing the knee, abduct
the ankle. If the knee joint abducts greater than the uninjured knee, the test is positive. This is suggestive of
a medical collateral ligament tear.
Question:
The dorsiflexors muscles in the foot include the:
posterior tibial muscle.
gastrocnemius.
toe flexors.
toe extensors. Correct
Explanation:
The dorsiflexors in the foot include the anterior tibial muscles and the toe extensors.
Question:
Thenar atrophy suggests:
an ulnar nerve disorder.
a median nerve disorder. Correct
a radial nerve disorder.
a superficial branch of the radial nerve.
