In which type of vertebrae do we find transverse foramen?
Cervical Vertebrae.
Lumbar Vertebrae.
Thoracic Vertebrae.
Sacral vertebrae.
The Correct Answer is A
The cervical vertebrae are the only vertebrae that have transverse foramina, which are openings in the transverse processes that allow the passage of the vertebral arteries and veins.
Choice B is incorrect because lumbar vertebrae do not have transverse foramina.
They have large bodies and short, thick transverse processes that serve as attachment sites for muscles.
Choice C is incorrect because thoracic vertebrae do not have transverse foramina.
They have costal facets on their transverse processes that articulate with the tubercles of the ribs.
Choice D is incorrect because sacral vertebrae do not have transverse foramina.
They are fused together to form the sacrum, which has four pairs of sacral foramina on each side that transmit sacral nerves and vessels.

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.
Correct Answer is ["Acetabulum"]
Explanation
acetabulum is the concave cavity located on the lateral surface of the hip bone.
It is formed by the fusion of the ilium, ischium, and pubis bones.
The acetabulum articulates with the head of the femur to form the hip joint, which is a ball-and-socket joint that allows for a wide range of movement.
The acetabulum is lined with articular cartilage, which provides a smooth surface for the head of the femur to move against.
The acetabulum is also surrounded by a fibrocartilaginous ring called the acetabular labrum, which deepens the socket and helps to stabilize the hip joint.
Injuries to the acetabulum can result in hip dislocations or fractures, which can be very painful and require medical intervention.
