Example Questions

Example Question #5 : Identifying Tendons And Ligaments

Which of the following is not a ligament in the shoulder?

Possible Answers:

Superior glenohumeral ligament

Acromioclavicular ligament

Coracoacromial ligament

Medial collateral ligament

Coracoclavicular ligament

Correct answer:

Medial collateral ligament

Explanation:

The medial collateral ligament (MCL) is not part of the shoulder, but is a ligament on the medial side of the knee.

The superior glenohumeral ligament, acromioclavicular ligament, coracoclavicular ligament, coracoacromial ligament are all ligaments of the shoulder. Major structures related to should functionality include the glenoid fossa, the acromion process, and the coracoid process, which are all structures of the scaupla. The humerus and clavicle articulate with the processes to form the shoulder joints.

Example Question #6 : Identifying Tendons And Ligaments

The calcaneal tendon is formed from the joined tendons of all of the following muscles except the __________.

Possible Answers:

Tendons from all of these muscles combine to form the calcaneal tendon

gastrocnemius

plantaris

popliteus 

soleus

Correct answer:

popliteus 

Explanation:

The calcaneal tendon (also called the Achilles tendon) is formed from the combined tendons of all the superficial muscles of the posterior leg. These muscles are the gastrocnemius, soleus, and plantaris.

The popliteus is a muscle of the posterior leg, however it is found in the deep layer. It functions in unlocking the knee from the extended position.

Example Question #7 : Identifying Tendons And Ligaments

Where could one find the coronary ligament?

Possible Answers:

Shoulder

Heart

Lungs

Pericardium

Knee

Correct answer:

Knee

Explanation:

There are two different coronary ligaments in the body. The coronary ligament of the liver serves to connect the liver to the inferior surface of the diaphragm; as this is not an answer option, we must be looking at the second type of coronary ligament.

The coronary ligament of the knee serves to connect the menisci to the tibial condyles, and is continuous with the joint capsule of the knee.

Example Question #8 : Identifying Tendons And Ligaments

Which of the following is a ligament found in the foot?

Possible Answers:

Anterior cruciate ligament

Cervical ligament

Oblique popliteal ligament

Arcuate popliteal ligament

Correct answer:

Cervical ligament

Explanation:

The anterior cruciate ligament stabilizes the knee by preventing excess anterior tibial translation. The oblique popliteal ligament stabilizes the posteromedial ligament. The arcuate popliteal ligament stabilizes the posterolateral knee capsule.The cervical ligament helps stabilize the subtalar joint.

Example Question #9 : Identifying Tendons And Ligaments

Which of the following hip movements, does the ischiofemoral ligament not resist?

Possible Answers:

External rotation

Extension

Internal rotation

Adduction

Correct answer:

External rotation

Explanation:

Depending on the portion of the ligament, the ischiofemoral ligament resists femoral (hip) extension, internal rotation, and adduction. The lateral fibers of this ligament resist internal rotation and extension, while its more superior fibers resist adduction. External rotation is resisted primarily by the iliofemoral ligament.

Example Question #10 : Identifying Tendons And Ligaments

The sustentaculum part of which bone?

Possible Answers:

Tibia

Navicular

Calcaneus

Talus

Correct answer:

Calcaneus

Explanation:

The sustentaculum tali projects from the medial calcaneus. It serves as an attachment site for the tibiocalcanel fibers of the deltoid ligament. Additionally, it serves an attachment for the plantar calcaneonavicular (spring) ligament.

Example Question #51 : Joints

Which of the following ligaments is not a part of the deltoid ligament of the ankle?

Possible Answers:

Tibiocalcaneal

Calcaneofibular

Tibionavicular

Posterior tibiotalar

Anterior tibiotalar

Correct answer:

Calcaneofibular

Explanation:

The calcaneofibular ligament is located on the lateral side of the ankle instead of the medial side where the deltoid ligament is located. All other ligaments are part of the deltoid ligament of the ankle.

Example Question #52 : Joints

Which of the following is the primary purpose of the posterior cruciate ligament (PCL)?

Possible Answers:

To prevent medial displacement of the tibia 

To resist hyperextension 

To resist hyperflexion

To prevent lateral displacement of the tibia 

To bind the anterior ends of the lateral and medial menisci 

Correct answer:

To resist hyperflexion

Explanation:

The posterior cruciate ligament is responsible for resisting hyperflexion of the knee joint. The anterior cruciate ligament is responsible for resisting hypertension of the knee joint. The transverse ligament is responsible for binding the anterior ends of the lateral and medial menisci.

Example Question #53 : Joints

Which ligament connects the laminae of the vertebral column and has a yellowish color due to the presence of elastin?

Possible Answers:

Nuchal ligament

None of these

Anterior longitudinal ligament

Ligamentum flavum

Posterior longitudinal ligament

Correct answer:

Ligamentum flavum

Explanation:

All the other answer choices are also ligaments of the spinal cord. The anterior and posterior longitudinal ligaments run along the bodies of the vertebra rather than the laminae, and the nuchal ligament is a thin flap that connects from the cervical spine to the occipital bone. It helps prevent too much forward flexion of the head.

Example Question #54 : Joints

Which of the following ligaments does not resist ankle inversion?

Possible Answers:

Anterior talofibular ligament

Cervical ligament

Deltoid ligament

Calcaneofibular ligament

Correct answer:

Deltoid ligament

Explanation:

The medial ankle ligaments primarily resist eversion. Accordingly, the deltoid ligament resists eversion, not inversion. Although the cervical ligament does resist ankle movements in multiple directions, it primarily resists inversion. The anterior talofibular ligament and the calcaneoufibular ligament both resist inversion when the ankle ins plantarflexed and dorsiflexed, respectively.
