In what type of fracture do we consider the bone to be shattered?
Transverse.
Spiral.
Comminuted.
Greenstick.
The Correct Answer is C
Choice A is incorrect because transverse fractures are the type of fractures where the bone has a horizontal fracture line.
They are usually caused by a strong force applied at a right angle to the bone shaft.
Choice B is incorrect because spiral fractures are the type of fractures where the bone has an angled fracture line that curves around the bone shaft.
They are usually caused by a twisting force applied to the bone.
Choice D is incorrect because greenstick fractures are the type of fractures where the bone is bent and partially broken on one side.
They are usually seen in children whose bones are softer and more flexible than adults.

Correct Answer is B
Explanation
The ethmoid bone is a part of the axial skeleton, not the appendicular skeleton.
The axial skeleton consists of the bones of the skull, vertebral column, ribs, and sternum.
Choice A is incorrect because the ulna is a part of the upper limb, which is supported by the pectoral girdle.
Choice C is incorrect because the ilium is a part of the hip bone, which forms the pelvic girdle.
Choice D is incorrect because the patella is a part of the lower limb, which is supported by the pelvic girdle.
Correct Answer is ["External rotation of the shoulder joint"]
Explanation
External shoulder rotation is the movement of the humerus bone away from the centerline of the body, rotating the arm so that the palm faces away from the body.
This movement is achieved by the contraction of the external rotator muscles of the shoulder, which include the infraspinatus, teres minor, and posterior fibers of the deltoid muscle.
The joint involved in external shoulder rotation is the glenohumeral joint, also known as the shoulder joint.
The shoulder joint is a ball-and-socket joint formed by the articulation between the head of the humerus bone and the glenoid cavity of the scapula bone.
This joint allows for a range of movements, including:
1. Internal shoulder rotation: This is the opposite movement of external rotation, in which the humerus bone rotates inward toward the centerline of the body, with the palm facing inward.
2. Shoulder flexion: This is the movement of the humerus bone forward and upward, bringing the arm closer to the body's front.
3. Shoulder extension: This is the movement of the humerus bone backward and downward, moving the arm away from the body's front.
4. Shoulder abduction: This is the movement of the humerus bone away from the body's midline, raising the arm out to the side.
5. Shoulder adduction: This is the movement of the humerus bone toward the body's midline, bringing the arm back down to the side of the body.
6. Shoulder horizontal abduction: This is the movement of the humerus bone away from the body's midline at shoulder height.
7. Shoulder horizontal adduction: This is the movement of the humerus bone toward the body's midline at shoulder height.
All of these movements of the glenohumeral joint are important for many daily activities, including reaching, throwing, pushing, pulling, and lifting.
