How Well Do You Know Your Bones?

Explanation
The femur, also known as the thigh bone, is the largest bone in the human body. It is located in the upper leg and is responsible for supporting the weight of the body and facilitating movement. The femur is also the strongest bone in the body, capable of withstanding a significant amount of force.

Explanation
Joints are the place where two bones meet. They are responsible for connecting bones together and allowing movement. Ligaments and tendons, on the other hand, are connective tissues that help stabilize and support joints, but they do not directly meet bones. The rib cage is a structure made up of bones and cartilage, and it does not represent the meeting point of two bones. Therefore, the correct answer is joints.

Explanation
The mandible bone, also known as the lower jaw bone, is the only movable bone in the human skull. It is connected to the skull by a joint called the temporomandibular joint (TMJ), allowing for movements such as opening and closing the mouth, chewing, and speaking. The other bones mentioned in the options - ethmoid bone, nasal bone, and lacrimal bone - are all located in the skull but are not movable.

Explanation
A hip fracture can lead to death in people at the age of 65 due to various reasons. The most common cause is complications that arise during surgery or post-surgery, such as infections, blood clots, or pneumonia. Additionally, hip fractures can also lead to immobility, which increases the risk of other health issues like pressure sores, urinary tract infections, and pneumonia. The combination of these factors can be life-threatening for older individuals, making hip fractures a serious concern in this age group.

Explanation
The clavicle, also known as the collarbone, is the correct answer because it is the most commonly broken bone in the human body. This is due to its location and structure, as it is a long, slender bone that is exposed and easily susceptible to fractures from falls, sports injuries, and accidents. The clavicle acts as a strut, providing support and stability to the shoulder and arm, making it prone to breaks.

Explanation
Toes are also known as phalanges. Phalanges are the bones that make up the digits of the foot. They are similar to the phalanges in the fingers of the hand. The term "phalanges" is commonly used in anatomy to refer to the bones in both the hands and feet.

Explanation
The correct answer is Radius and Ulna. The radius and ulna are the two bones that make up the lower arm. The radius is located on the thumb side of the forearm, while the ulna is located on the pinky side. These two bones work together to allow for movement and flexibility in the forearm, as well as providing support and protection for the muscles and tendons in the area.

Explanation
The human skull is composed of 22 bones. These bones include the cranium, which protects the brain, and the facial bones, which form the structure of the face. The skull bones are connected by sutures, which allow for limited movement and flexibility. Overall, the 22 bones in the human skull provide protection and support for the brain and facial features.

Explanation
The xiphoid process is the correct answer because it is the bottom portion of the sternum. It is a small, cartilaginous extension at the tip of the sternum that serves as an attachment point for some abdominal muscles. The manubrium is the upper portion of the sternum, while carpal refers to the bones in the wrist and incus is one of the three small bones in the middle ear.
