Human Skeletal System Quiz

The correct answer is humerus. The humerus is a long bone located in the upper arm, between the shoulder joint and the elbow joint. It is the largest bone in the upper limb and plays a crucial role in the movement and stability of the arm. The other options mentioned (patella, ulna, and fibula) are bones found in different parts of the body and are not located in the upper arm.

The femur and tibia meet at the knee joint. The knee joint is a hinge joint that allows for flexion and extension of the leg. It is the largest joint in the body and is responsible for bearing the weight of the body and facilitating movements such as walking, running, and jumping. The hip joint connects the femur to the pelvis, while the ankle joint connects the tibia to the foot. The wrist joint is located in the upper extremity, not the lower extremity where the femur and tibia are found.

The humerus and ulna meet at the elbow. The elbow joint allows for flexion and extension of the forearm, and it is where the upper arm bone (humerus) and the forearm bone (ulna) come together. This joint is responsible for the movement of the forearm, allowing us to bend and straighten our arm. The hip, knee, and wrist are not correct answers as they are joints where different bones meet, not the humerus and ulna.

The humerus is a long bone located in the upper limbs of the body. It is the bone of the upper arm and is part of the appendicular skeleton, not the axial skeleton. It forms the connection between the shoulder and the elbow joints and plays a crucial role in the movement and stability of the arm.

The words "true, false, and floating" are related to the ribs because they refer to different types of ribs found in the human body. True ribs are directly attached to the sternum, false ribs are indirectly attached to the sternum, and floating ribs are not attached to the sternum at all. These terms are used to describe the different classifications and locations of the ribs in the skeletal system.

The mandible is the correct answer because it is the facial bone that contains the lower teeth. The mandible, also known as the jawbone, is the largest and strongest facial bone and forms the lower part of the skull. It houses the lower teeth and plays a crucial role in chewing, speaking, and overall facial structure.

The terms cervical, thoracic, lumbar, sacral, and coccygeal are all related to the different regions of the vertebral column. These regions represent the different sections of the spine, with the cervical vertebrae being located in the neck, the thoracic vertebrae in the upper back, the lumbar vertebrae in the lower back, the sacral vertebrae in the pelvis, and the coccygeal vertebrae at the base of the spine. Therefore, the correct answer is vertebrae.

The metacarpal bones form the palm of the hand. These are the five long bones that connect the wrist to the fingers. They are located between the carpals (wrist bones) and the phalanges (finger bones). The metacarpal bones provide support and stability to the hand, allowing for various movements and functions such as gripping and grasping objects.

The ulna is not located in the lower limbs. The femur, tibia, and tarsals are all bones that are found in the lower limbs. The femur is the thigh bone, the tibia is the shin bone, and the tarsals are the bones that make up the ankle. The ulna, on the other hand, is a bone that is located in the forearm.

The atlas and axis are vertebrae located in the neck region of the spine. They are responsible for supporting the head and allowing for its movement. The atlas is the first cervical vertebra, which supports the skull, while the axis is the second cervical vertebra, which allows for rotation of the head. Together, they form a crucial part of the vertebral column and play a vital role in the movement and stability of the neck and head.

The epiphysis is located at the end of a long bone. It is a rounded, bulbous structure that forms the joint surface and is covered with articular cartilage. The epiphysis is responsible for the growth and development of the bone, as well as providing a point of attachment for ligaments and tendons. It contains red bone marrow, which is responsible for producing blood cells. The diaphysis refers to the shaft of the long bone, the periosteum is the outer covering of the bone, and the medullary cavity is the hollow space within the bone shaft.

The diaphysis is the correct answer because it refers to the shaft of a long bone. The diaphysis is the long, cylindrical portion of a bone between the two ends, known as the epiphyses. It is composed mainly of compact bone and contains the medullary cavity, which houses bone marrow. The diaphysis provides support and strength to the bone and is responsible for transmitting forces during movement.

The bone that is referred to as the cheekbone is called the zygomatic bone. It is a facial bone that forms the prominence of the cheek and contributes to the structure of the eye socket. The zygomatic bone connects with other bones such as the maxilla and the temporal bone, but it is specifically known as the zygomatic bone or the zygoma.

The mandible is the correct answer because it is the only bone listed that is found in the skull but not in the cranium. The cranium refers specifically to the bones that form the top, back, and sides of the skull, while the mandible is the lower jawbone that is separate from the cranium.

Foramen and meatus are both anatomical terms used to describe openings in the body. A foramen is a hole or passage in a bone, while a meatus refers to a natural body opening or canal. These openings serve various functions, such as allowing nerves, blood vessels, or other structures to pass through or facilitating the flow of fluids. Therefore, the correct answer for this question is "openings."

The femur is the correct answer because it is the bone that is distal to the acetabulum (hip socket) and proximal to the patella (kneecap). The femur is the longest and strongest bone in the human body and it connects the hip bone to the knee bone, making it the only bone that fits the given description.

The bone that is described as the lower leg, shin, and medial malleolus is the tibia. The tibia is one of the two long bones in the lower leg, located on the inner side. It is commonly known as the shin bone and is responsible for bearing most of the body's weight. The medial malleolus is the bony prominence on the inner side of the ankle, which is formed by the tibia. Therefore, the correct answer is tibia.

The coxal bone is formed by the ischium, ilium, and pubis. These three bones come together to form the hip bone or the coxal bone. The sacrum is a separate bone located at the base of the spine, while the cranium refers to the skull. The breast bone, also known as the sternum, is located in the chest area and is not part of the hip bone. Therefore, the correct answer is coxal bone.

The coxal bone is not a bone of the vertebral column. The vertebral column, also known as the spine or backbone, is made up of a series of bones called vertebrae. The atlas, sacrum, and coccyx are all vertebrae that make up the vertebral column. However, the coxal bone, also known as the hip bone, is not part of the vertebral column. It is located in the pelvic region and forms the hip joint with the femur bone.

The epiphyseal disc is responsible for growth. It is located at the end of long bones and is responsible for the lengthening of bones during childhood and adolescence. The disc contains cartilage cells that divide and multiply, allowing the bone to grow in length. This process is crucial for the overall growth and development of the body.

The coronal suture is a fibrous joint that connects the frontal bone to the parietal bones of the skull. This suture is located at the anterior portion of the skull and runs from one side to the other. It is classified as an immovable joint, meaning that it allows for minimal to no movement. Therefore, the correct answer is the frontal bone, as it forms an immovable joint with the parietal bones through the coronal suture.

The occipital bone is located at the back of the skull and contains the foramen magnum, which is a large opening that connects the brain with the spinal cord. This opening allows the passage of important structures such as the spinal cord, blood vessels, and nerves. The parietal bone forms the sides and roof of the skull, while the sphenoid bone is located at the base of the skull. The atlas is the first cervical vertebra, which supports the head and allows for its movement. Therefore, the occipital bone is the correct answer as it is the bone that contains the foramen magnum.

The correct answer is maxilla because the maxilla is a facial bone that forms the upper jaw and contains the palatine process. The palatine process of the maxilla forms the anterior part of the hard palate, which is the bony structure that separates the oral and nasal cavities. The mandible is the lower jaw bone, the zygomatic bone forms part of the cheekbone, and the sphenoid bone is located at the base of the skull.

The ulna is the correct answer because it is one of the two bones in the forearm, along with the radius. The ulna is located on the inner side of the forearm and contains the olecranon process, which is a bony projection at the upper end of the ulna that forms the bony prominence of the elbow. The radius, scapula, and humerus are not associated with the olecranon process.

Trabecular bone, also known as spongy or cancellous bone, is a type of bone tissue that has a porous and honeycomb-like structure. It is found at the ends of long bones, in the vertebrae, and in the interior of flat bones. Trabecular bone provides support and strength to the skeleton while also allowing for flexibility and shock absorption. It is less dense than compact bone and contains a network of interconnected trabeculae, which help to distribute forces and maintain bone integrity.
