Anatomy Quiz on Clavicle and Joints

The movement of the clavicle around a vertical axis, causing it to turn inwards or outwards. Think of rotating a doorknob.

The largest foramen (opening) in the pelvis, located below the sacrum. It allows for the passage of important structures such as nerves and blood vessels.

The joint between the atlas (C1 vertebrae) and the occipital bone of the skull, allowing for head nodding and tilting.

The distance between the promontory of the sacrum and the symphysis pubis. It is an important measurement for determining the size of the pelvic inlet and assessing fetal passage through the pelvis.

A ligament found inside the hip joint, connecting the head of the femur to the acetabular notch. (acetabular notch is part of the pelvis)

The transverse arch of the foot, formed by the metatarsal bones, which provides stability and support to the foot.

The joints formed between the ribs II to VII and the sternum. These joints allow the ribs to move up and down during respiration.

The floating ribs articulate with the vertebral column only through the costotranverse joint, which is a joint between the rib and the transverse process of the vertebrae. The floating ribs do not articulate with the sternum.

The articulation between the clavicle and the sternum, this is a saddle joint.

The joint between the clavicle and the acromion process of the scapula.

This joint is formed by the head of the humerus and the glenoid cavity of the scapula.

A joint formed between the atlas and the axis, allowing for rotation of the head.

The articulation between the sacrum and the ilium, this is a synovial, plane joint.

This is the superior opening of the thorax. The superior opening of the thorax is bounded by the manubrium of the sternum, first rib, and first thoracic vertebra.

This curvature of the spine is present at birth and can be seen in the chest region.

An inward curve of the spine, typically found in the cervical and lumbar regions. It helps maintain balance and flexibility.

The angle formed by the movement axes of the left and right ribs is a crucial factor in respiratory mechanics, allowing for efficient expansion of the rib cage during inhalation.

The movement of the thigh towards the midline of the body. It involves motion around the anterior-posterior axis of the hip joint.

The thoracic cage is the bony structure of the chest, composed of the thoracic vertebrae, ribs, and sternum. This structure protects vital organs and plays a significant role in respiration.

The tendon of the long head of the biceps brachii muscle passes through the humeral joint, contributing to joint stability and enabling arm movement.

The male pelvis is characterized by its truncated cone shape, reflecting differences in reproductive functions.

Diameter obliqua is the largest diagonal measurement of the pelvic inlet in females. It is a key indicator of pelvic capacity and fetal passage during childbirth.

This ligament is known for its exceptional strength, providing crucial stability to the hip joint. It plays a significant role in preventing excessive hip extension.
