This set of Human Anatomy Assessment Questions and Answers focuses on “Syndesmology – Articulations of Trunk, Upper & Lower Extremity”.
1. Which of the following connects margins of lateral masses of atlas with those of posterior articular surfaces of axis?
a) Articular capsules
b) Posterior atlantoaxial
c) Anterior atlantoaxial
d) The transverse
View Answer
Explanation: Articular capsules are thin, loose and connect the axis. Each is strengthened at posterior and medial part by an accessory ligament which is attached below to the body of axis near base of odontoid process.
2. Which of the following is covered by parotid gland?
a) Articular disc
b) Sphenomandibular
c) Temporomandibular ligament
d) Stylomandibular
View Answer
Explanation: Temporomandibular ligament consists of two short narrow fascicule one in front of other attached above to the lateral surface of zygomatic arch and to tubercle on its lower border. It is covered by parotid gland and by integument.
3. Name the ligament that connects the anterior and posterior surface of 7th coastal cartilage?
a) The costoxiphoid ligament
b) The radiate sternocoastal
c) The interarticular sternocoastal
d) Articular capsules
View Answer
Explanation: The costoxiphoid ligament and sometimes the sixth to front and back of xiphoid process. They vary in length and breadth in different subjects; those on back of joint are less distinct than those in front.
4. Ligaments connecting bones of the pelvis with each other may be divided into ________ groups.
a) 3
b) 5
c) 2
d) 4
View Answer
Explanation: They can be divided into 4 groups.
1) Those connecting sacrum and ilium
2) Those passing between sacrum and coccyx
3) Those uniting the sacrum and coccyx
4) Those between two public bones.
5. The most important mechanical function of pelvis is to transmit the weight of trunk and upper limbs to lower extremity.
a) True
b) False
View Answer
Explanation: Pelvis girdle supports and protects contained viscera and affords surfaces for attachment of trunk and lower limb muscles. The most important mechanical function of pelvis is to transmit the weight of trunk and upper limbs to lower extremity.
6. The sternoclavicular articulation is a _________ arthrodial joint.
a) Single
b) Double
c) Triple
d) 4 layered
View Answer
Explanation: The sternoclavicular articulation is a double arthrodial joint. The parts entering into its formation are the sterna end of clavicle upper and lateral part of manubrium and cartilage of the first rib.
7. The sternoclavicular joint is a type of __________ joint.
a) Hinge joint
b) Ball and socket
c) Saddle type
d) Pivot
View Answer
Explanation: The sternoclavicular joint is a type of saddle join. It allows movement of clavicle predominately in anterioposteior and vertical planes although some rotation occur.
8. Acrominoclaviclular joint is partially filled with a thick pad pf cartilage known as meniscus.
a) True
b) False
View Answer
Explanation: Acrominoclaviclular joint is located at the tip of the shoulder. It allows the joint to move.
9. How many ligaments are present in a wrist joint?
a) 4
b) 3
c) 2
d) 5
View Answer
Explanation: There are 4 ligaments are present in the wrist joint. They are Palmer radiocarpel, dorsal radiocarpel, ullnar collateral and radial collateral.
10. Which of the following is not a part of the wrist joint?
a) Radius
b) Ulna
c) Scaphoid
d) Articular disc
View Answer
Explanation: Ulna is not a part of the wrist joint. Ulna articulates with radius first proximal to wrist joint at distal radioulnar joint.
11. Which of the following ligament is called y shaped ligament of Bigelow?
a) The Ischiocapsular
b) The glenoidal labrum
c) The Pubocapsular
d) Illiofemoral ligament
View Answer
Explanation: Illiofemoral ligament is a band of great strength which lies in front of joint. It is intimately connected with capsule and serves to strengthen it.
12. Knee joint consists of 5 joints within a single synovial cavity.
a) True
b) False
View Answer
Explanation: Knee joint consists of 3 joints within a single synovial cavity. They are medial condylar joint, lateral condylar joint and patellofemoral joint.
13. Ligamentous fibers that provides stability to hip joint capsule is __________
a) Lateral ligament
b) Acetabular labrum
c) Retinacular fibres
d) Deltoid ligament
View Answer
Explanation: Blood supply to head run under Retinacular fibers. Fibers of capsule reflected along neck to articular margin called Retinacular fibers.
14. Joint with two articulations in one capsule medial side connects distal end of tibia and medial malleolus to talus. Lateral side connects malleolus of fibula with talus?
a) Talocrural joint
b) Lateral meniscus
c) Lateral ligament
d) Patellar ligament
View Answer
Explanation: Talocrural joint is ankle joint located at lower limb. It is formed by the bones of the leg and the foot- the tibia fibula and talus.
15. Diarthrosos and synovial articulation between condyles of femur and condyles of tibia is ______ joint.
a) Metatarsophalangeal joints
b) Tibiofemoral joints
c) Tarsometatarsals joints
d) Patellofemoral joints
View Answer
Explanation: Tibiofemoral joints are hinge joint that joins the distal femur to proximal tibia. The articulation occurs between medial and lateral femoral condyles and the tibial condyles.
