The zygomatic bones, also known as the malar bones, are the cheekbones, so humans normally have two of these. They are small, quadrangular-shaped, bones and they are located under and alongside the orbital cavities.
2. Ear
Answer: Incus
The incus, along with the malleus and stapes, make up the ossicles of the middle ear and are among the smallest bones in the human body. The incus is at the center, connecting the malleus and the stapes. It is shaped somewhat like an anvil, which is also its alternative name.
3. Neck
Answer: Hyoid bone
Also called the lingual or tongue bone, the hyoid bone is known for not being directly connected to any other bone; instead, it is attached by muscles or ligaments. It is an irregular, u-shaped, bone consisting of a body and two sets of horns.
4. Shoulder
Answer: Clavicle
The clavicles are long bones that are located on either side of the sternum, connecting to the shoulder blades (scapulas). Clavicles are the only horizontal long bones in the body, and they are one of the most frequently broken bones.
5. Chest
Answer: Sternum
Also called the breastbone, the sternum is a long bone located in the front of the rib cage. It is separate from the rib cage but connected to the first seven pairs of ribs via cartilage. It is a flat bone and is one of the largest and longest such bones in the body.
6. Arm
Answer: Ulna
The ulna is a long bone in the forearm that runs from the elbow to the wrist. It is longer and larger than the radius, the other long bone in the forearm, to which it runs parallel. It is located on the inside of the arm, near the little finger.
7. Hand
Answer: Trapezium
The trapezium is one of the four carpal bones in the distal row of the hand. It is a small, irregular-shaped, bone located at the lower side of the hand next to the thumb. It is a different bone from the trapezoid, which is located next to it.
8. Spine
Answer: Sacrum
The sacrum is the large, wedge-shaped bone at the bottom of the spine that fits into the back part of the pelvic cavity. It is created by the fusing of the five sacral vertebrae, S1-S5, which occurs during early adulthood. It is sexually dimorphic, with the female sacrum being smaller and wider than the male.
9. Leg
Answer: Patella
The patella, also known as the kneecap, is the triangular-shaped bone at the front of the knee joint. It is a sesamoid bone, held in place by muscle, which connects it to the tibia and the femur. It is the largest of the sesamoid bones in the body.
10. Foot
Answer: Calcaneus
The calcaneus, also known as the heel bone, is the largest bone in the foot. It is one of seven bones, called tarsals, that make up the hindfoot and midfoot. The calcaneus is an irregularly-shaped bone located below the three bones that make up the ankle joint (the talus, tibia and fibula).
