Radiology Quiz on Anatomical Terms of Bones

The correct answer, 'the tarsals', refers to the bones in the ankle. The incorrect answers are: 'the fibula' is a bone in the leg, 'the patella' is the kneecap, and 'the phalanges' are the bones in the toes.

The body (centrum) of the vertebrae is the largest part of a vertebra, which is more or less cylindrical in shape. Its upper and lower surfaces give attachment to the intervertebral fibrocartilages. This structure plays a crucial role in bearing weight and providing stability to the spine.

Cervical vertebrae refer to the first seven vertebrae in the spinal column located in the neck region. Lumbar vertebrae are in the lower back, thoracic vertebrae are in the mid-back, and sacral vertebrae are in the pelvis region.

The correct term for the collarbone is clavicle, not scapula, humerus, or femur.

The coccyx, also known as the tailbone, is the small, triangular bone located at the bottom of the vertebral column. It is made up of three to five fused vertebrae and serves as a point of attachment for various muscles, ligaments, and tendons.

The ethmoid bone is a cranial bone that is located between the orbits and plays a crucial role in the structure of the superior nasal cavity. It contains multiple perforations for the olfactory nerves. The frontal bone forms the forehead, the sphenoid bone is a complex bone in the base of the skull, and the maxilla is a facial bone.

The thigh bone is medically known as the femur, which is the longest and strongest bone in the human body. The tibia and fibula are bones in the lower leg, while the patella is the kneecap.

The carpals are a group of eight bones that make up the wrist. The metacarpals are the bones in the palm of the hand, the phalanges are the bones in the fingers, and the radius and ulna are bones in the forearm.

The cervical vertebrae that aren't the axis or atlas are specifically numbered C-3 through C-7. C-1 and C-2 are the atlas and axis respectively, while C-8, C-9, C-10, C-11, and C-12 are thoracic vertebrae.

The foramen magnum is the large opening at the base of the skull through which the spinal cord passes. It is located in the occipital bone. The occipital foramen is a separate opening in the occipital bone, while the temporal and maxillary foramina are located in different bones of the skull.

The head of the humerus is the correct answer as it is the large rounded part at the top of the humerus that forms the glenohumeral joint with the scapula's glenoid cavity. The other options are incorrect as the glenoid cavity is part of the scapula, the radius bone is located in the forearm, and the olecranon process is part of the ulna in the elbow.

The correct answer is 'Frontal' as the yellow region in the picture corresponds to the frontal lobe of the brain. The temporal, parietal, and occipital lobes are located in different regions of the brain.

The acetabulum is the cup-shaped socket in the pelvis where the head of the femur (thigh bone) fits into, forming the hip joint. The femur head is the rounded part of the thigh bone that fits into the acetabulum. The ilium is a bone in the pelvis, and the ischium is the lowest of the three major bones that make up each half of the pelvis.

The Atlas (C1) is the topmost cervical vertebrae in the spine, it has no body and its primary function is to support the skull and connect it to the spine. The Axis (C2) is known for its unique odontoid process. C3 and C5 are other cervical vertebrae, but they do not specifically connect the foramen magnum to the spine like the Atlas does.

The axis is the second cervical vertebra, which has a body that helps connect the foramen magnum to the spine, distinguishing it from the atlas and other vertebrae in the cervical and thoracic regions.

The correct term for the ends of a long bone diaphysis located in the middle is Epiphysis, which refers to the rounded ends of the bone that are involved in joint articulation.

The fibula is the smaller of the two bones located in the lower leg, next to the tibia. It plays a role in stabilizing the ankle and supporting the muscles of the lower leg. The tibia is the larger and stronger of the two lower leg bones. The patella, also known as the kneecap, is a small bone in the front of the knee joint. The femur is the longest bone in the human body, located in the thigh region.

The correct answer is Glenoid cavity, also known as fossa, which is the shallow, concave surface on the lateral angle of the scapula that articulates with the head of the humerus to form the shoulder joint. The other options mentioned are different anatomical structures of the scapula that do not meet the description provided in the question.

The head of the femur is the rounded end of the thigh bone that fits into the hip socket. It is the highest part of the thigh bone and plays a crucial role in hip joint movement.

The head of a rib is the part closest to the vertebral column, where it articulates with the vertebrae. The head of radius is actually a structure in the forearm, not related to ribs. The knee cap and elbow joint are also unrelated to the articulation of ribs with the vertebral column.

The coronoid process is a projection on the ulna bone that articulates with the humerus to form part of the elbow joint. The radial tuberosity, styloid process of ulna, and trochlear notch are other features of the ulna bone but do not specifically form the stable hinge-joint with the humerus.

The anatomical neck of humerus is the correct term for the indentation distal to the head of the humerus. The surgical neck of humerus is located slightly below the head and is a common site for fractures. The tubercle of humerus refers to a small bony projection near the head of the humerus. The greater tubercle of humerus is a specific bony prominence on the lateral aspect of the proximal humerus.
