Ultimate Trivia On Kinesiology! Quiz

1.

The clavicle connects

A.

Many ligaments and vessels.
B.

To a variety of other structures.
C.

Upper extremities to axial skeleton atsternoclavicular joint.
D.

None of the above.

Correct Answer
C. Upper extremities to axial skeleton atsternoclavicular joint.

Explanation
The clavicle connects the upper extremities to the axial skeleton at the sternoclavicular joint. This joint is where the clavicle attaches to the sternum, allowing for movement and stability of the shoulder girdle. The clavicle also serves as a site of attachment for ligaments and vessels, further supporting its role in connecting different structures within the body.

What are the bony landmarks of the scapula?

Correct Answer
Sup/inf angle, vert border, axillary border, spine , coracoid and acromion process and glenoid fossa

Explanation
The bony landmarks of the scapula include the superior and inferior angles, the vertebral border, the axillary border, the spine, the coracoid process, the acromion process, and the glenoid fossa. These landmarks help in identifying and understanding the anatomy and function of the scapula. The superior and inferior angles determine the orientation of the scapula, while the vertebral and axillary borders provide attachment sites for muscles. The spine divides the scapula into two unequal portions and serves as a point of attachment for muscles. The coracoid and acromion processes are important for muscle and ligament attachments, and the glenoid fossa is the shallow socket that articulates with the humerus to form the shoulder joint.

3.

The clavicle attaches to the scapula at

A.

The sternum.
B.

The coracoid process.
C.

Acromioclavicular joint.
D.

Supraspinatus.

Correct Answer
C. Acromioclavicular joint.

Explanation
The clavicle attaches to the scapula at the acromioclavicular joint. The acromioclavicular joint is located at the outer end of the clavicle and connects it to the acromion process of the scapula. This joint allows for movement and stability of the shoulder, as well as the transmission of forces from the upper limb to the axial skeleton. The sternum, coracoid process, and supraspinatus are not directly involved in the attachment of the clavicle to the scapula.

4.

The bony landmarks of the clavicle are

A.

Coracoid process, infraspinatus.
B.

Acromion, sternoclavicular joint.
C.

Sternal end, acromial end and body.
D.

None of the above.

Correct Answer
C. Sternal end, acromial end and body.

Explanation
The correct answer is sternal end, acromial end, and body. The clavicle, also known as the collarbone, has three main bony landmarks. The sternal end is the medial end of the clavicle that articulates with the sternum. The acromial end is the lateral end of the clavicle that articulates with the acromion process of the scapula. The body of the clavicle is the long, curved portion that connects the sternal and acromial ends. Therefore, the correct answer includes all three of these bony landmarks.

5.

The sternum is located

A.

Superior to the scapula.
B.

Midline of anterior thorax.
C.

Laterally to clavicle.
D.

None of the above.

Correct Answer
B. Midline of anterior thorax.

Explanation
The sternum is a flat bone located in the midline of the anterior (front) thorax. It is commonly referred to as the breastbone and serves as an attachment point for several muscles and ribs. The scapula, on the other hand, is a triangular bone that is located on the posterior (back) side of the thorax. Therefore, the correct answer is that the sternum is located in the midline of the anterior thorax.

6.

Superior end of sternum provides attachment to the

A.

Clavicle
B.

Scapula
C.

Acromion
D.

None of the above.

Correct Answer
A. Clavicle

Explanation
The superior end of the sternum provides attachment to the clavicle. This means that the clavicle bone is connected to the top part of the sternum, forming a joint called the sternoclavicular joint. This joint allows for movement of the shoulder and helps to stabilize the upper limb. The scapula and acromion are not directly attached to the sternum, so they are not the correct answer.

7.

Sternum divided into three parts which are

A.

Glenoid process, lateral border and fossa.
B.

Manubrium, body and xiphoid process.
C.

Clavicle, scapula and coracoid.
D.

None of the above.

Correct Answer
B. Manubrium, body and xipHoid process.

Explanation
The correct answer is manubrium, body and xiphoid process. The sternum, also known as the breastbone, is a flat bone located in the center of the chest. It is divided into three parts: the manubrium, which is the uppermost portion and articulates with the clavicles and first rib; the body, which is the middle and largest part; and the xiphoid process, which is the smallest and lowest part. These three parts together form the sternum. The other options mentioned (glenoid process, lateral border, fossa, clavicle, scapula, coracoid) are not parts of the sternum.

The sternoclavicular joint (SC) provides shoulder girdle and is directly attached to the

A.

Trunk
B.

Cartilage
C.

Tendon
D.

None above

Correct Answer
A. Trunk

Explanation
The sternoclavicular joint (SC) provides shoulder girdle and is directly attached to the trunk. This means that the SC joint connects the shoulder girdle to the trunk of the body. It is responsible for allowing movement and stability of the shoulder. The trunk refers to the main part of the body, including the chest and abdomen. Therefore, the correct answer is trunk.

9.

The articulation of SC joint is between the

A.

Scapula and lateral border
B.

Intercoastal ribs
C.

Sternum and medial end of the clavicle
D.

None of the above.

Correct Answer
C. Sternum and medial end of the clavicle

Explanation
The articulation of the SC joint refers to the joint between the sternum and the medial end of the clavicle. This joint allows for movement and stability of the shoulder girdle. The scapula and lateral border, as well as the intercoastal ribs, are not directly involved in the articulation of the SC joint. Therefore, the correct answer is sternum and medial end of the clavicle.

The SC joint is a

A.

Hinge joint
B.

Deep tendon joint
C.

Synovial joint
D.

None of the above.

Correct Answer
C. Synovial joint

Explanation
The SC joint refers to the sternoclavicular joint, which is a synovial joint. Synovial joints are characterized by the presence of a synovial cavity filled with synovial fluid, which allows for smooth movement between the articulating bones. The SC joint is a synovial joint because it is surrounded by a joint capsule and contains synovial fluid, enabling movement between the sternum and clavicle.

The joint disc of SC joint is a cushion or shock absorber between the

A.

Scapula and acromiom
B.

The xiphoid and corocoid
C.

Sternum and clavicle
D.

None of the above.

Correct Answer
C. Sternum and clavicle

Explanation
The joint disc of the SC joint is a cushion or shock absorber between the sternum and clavicle. This means that it helps to absorb any impact or pressure that is placed on the joint during movement or activities. By acting as a cushion, the joint disc helps to protect the bones and surrounding tissues from damage or injury. This explanation is supported by the fact that the other options mentioned (scapula and acromion, xiphoid and coracoid) are not correct, as they do not accurately describe the location of the joint disc in the SC joint.
