Example Questions
Example Question #51 : Joints
Which of the following ligaments is not a part of the deltoid ligament of the ankle?
Anterior tibiotalar
Tibiocalcaneal
Tibionavicular
Posterior tibiotalar
Calcaneofibular
Calcaneofibular
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)?
To resist hyperflexion
To resist hyperextension
To prevent medial displacement of the tibia
To bind the anterior ends of the lateral and medial menisci
To prevent lateral displacement of the tibia
To resist hyperflexion
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?
Ligamentum flavum
Anterior longitudinal ligament
Nuchal ligament
None of these
Posterior longitudinal ligament
Ligamentum flavum
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?
Cervical ligament
Anterior talofibular ligament
Calcaneofibular ligament
Deltoid ligament
Deltoid ligament
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.
Example Question #11 : Identifying Tendons And Ligaments
Which ligament, when sprained, is associated with a separated shoulder?
Joint capsule
Acromioclavicular ligament (AC)
Deltoid ligament
Sternoclavicular ligament (SC)
Coracoclavicular ligament
Acromioclavicular ligament (AC)
The AC ligament is affected when a sprain occurs causing a "separated shoulder." This ligament connects the acromion to the clavicle.
Example Question #12 : Identifying Tendons And Ligaments
In which joint would you find the ligament of Wrisberg?
Ankle (talocrural joint)
Shoulder (glenohumeral joint)
Knee (tibiofemoral joint)
Hip (coxafemoral joint)
Knee (tibiofemoral joint)
The ligament of Wrisberg is better known as the posterior meniscofemoral ligament. As the name suggests, it is found in the knee. It extends from the posterior horn of the lateral meniscus to the medial femoral condyle. Although its function is still being researched, current understanding suggests that the ligament stabilizes the meniscus to optimize contact between it and the femur.
Example Question #13 : Identifying Tendons And Ligaments
During muscle contraction, which component(s) of the sarcomere shorten(s)?
The H-zone and I-band
The A-band only
The I-band only
The A-band and H-zone
The H-zone only
The H-zone only
Muscle contraction results in both the H-zone and I-bands shortening, but the A-band remains the same length (A band is Always the same). The Z-line is a static structure and doesn't change size.
