Identify the anatomical movement illustrated below and state the joint involved (for example flexion of the knee joint).
The Correct Answer is ["Scapula protraction at the scapulothoracic joint."]
Scapula protraction refers to the movement of the shoulder blade (scapula) away from the spine, toward the front of the body.
This movement is also known as scapular abduction or anterior scapular tilt.
The joint involved in scapula protraction is the scapulothoracic joint, which is not a true joint, but rather a functional joint formed by the articulation between the scapula and the thorax.
The scapula is a flat bone that glides over the back of the ribcage, allowing for a wide range of movements of the arm.
Other movements of the scapulothoracic joint include:
Scapula retraction: This refers to the movement of the shoulder blade towards the spine, away from the front of the body.
This movement is also known as scapular adduction or posterior scapular tilt.
Scapula elevation: This refers to the movement of the shoulder blade upwards towards the ears.
This movement is also known as the upward rotation of the scapula.
Scapula depression: This refers to the movement of the shoulder blade downwards towards the feet.
This movement is also known as a downward rotation of the scapula.
Scapula upward tilt: This refers to the movement of the upper border of the shoulder blade upwards, towards the head.
This movement is also known as superior scapular rotation.
Scapula downward tilt: This refers to the movement of the upper border of the shoulder blade downwards, towards the feet.
This movement is also known as inferior scapular rotation.
All of these movements are important for proper shoulder function and are necessary for a wide range of daily activities, such as reaching, lifting, pushing, and pulling.

Correct Answer is D
Explanation
The transverse foramina are openings in the transverse processes of the cervical vertebrae that allow the passage of the vertebral arteries and veins.
They are not found on any other vertebrae.
Choice A is incorrect because spinous processes are bony projections on the posterior aspect of all vertebrae that serve as attachment sites for muscles and ligaments.
Choice B is incorrect because transverse processes are lateral projections on all vertebrae that serve as attachment sites for muscles and ribs.
Choice C is incorrect because costal facets are articular surfaces on the thoracic vertebrae that articulate with the heads of the ribs.
They are found on all thoracic vertebrae except T11 and T123.
Correct Answer is B
Explanation
The rib is a part of the axial skeleton, not the appendicular skeleton.
The axial skeleton
Choice A is incorrect because the clavicle is a part of the pectoral girdle, which connects the upper limbs to the axial skeleton.
Choice C is incorrect because the femur is a part of the lower limb, which is supported by the pelvic girdle.
Choice D is incorrect because the scaphoid is a part of the carpals, which are bones of the wrist in the upper limb.
