Define: Mandible | The lower jawbone, which is the largest and strongest bone in the face and holds the lower teeth. She had a dental procedure to correct the alignment of her mandible. |
Define: Maxilla | The upper jawbone that forms the central part of the facial skeleton and holds the upper teeth. The orthodontist noted that the maxilla was slightly misaligned. |
Define: Zygomatic Bone | The bone that forms the prominent part of the cheek and the outer edge of the eye socket. He sustained an injury to his zygomatic bone during the game. |
Define: Nasal Bone | Two small, rectangular bones that form the bridge of the nose. The doctor confirmed that the nasal bones were intact after the accident. |
Define: Hyoid Bone | A U-shaped bone in the neck that supports the tongue and is not directly attached to other bones. The pathologist examined the hyoid bone for signs of trauma. |
Define: Clavicle | Also known as the collarbone, it connects the arm to the body and sits above the first rib. He fractured his clavicle in a cycling accident. |
Define: Scapula | The shoulder blade that connects the humerus (upper arm bone) with the clavicle. The athlete experienced pain in her scapula after the workout. |
Define: Sternum | The flat bone located in the center of the chest, also known as the breastbone, which connects the ribs. The doctor pressed on the patient’s sternum to assess for tenderness. |
Define: Ribs | The long, curved bones that form the rib cage, protecting the thoracic cavity and its organs. He suffered a fracture in one of his ribs after the fall. |
Define: Humerus | The long bone in the upper arm that extends from the shoulder to the elbow. The x-ray revealed a break in the humerus. |
Define: Radius | One of the two long bones in the forearm, located on the thumb side when the palm is facing up. She sprained her radius during the gymnastics routine. |
Define: Ulna | The second of the two long bones in the forearm, located on the opposite side of the radius. The fracture was found in the ulna after the injury. |
Define: Carpals | The eight small bones that make up the wrist, allowing for a wide range of motion. The doctor examined the carpals for any signs of arthritis. |
Define: Metacarpals | The five bones in the hand that connect the wrist to the fingers. She fractured one of her metacarpals while playing basketball. |
Define: Phalanges (Fingers/Toes) | The bones of the fingers and toes, with each finger having three phalanges and the thumb having two. He injured his phalanges while practicing the piano. |
Define: Vertebrae | The series of small bones that form the vertebral column (spine) and protect the spinal cord. The MRI showed degeneration of the vertebrae in her lower back. |
Define: Cervical Vertebrae | The seven vertebrae in the neck region of the spine, labeled C1 to C7. The chiropractor adjusted her cervical vertebrae to relieve neck pain. |
Define: Thoracic Vertebrae | The twelve vertebrae in the upper and mid-back, labeled T1 to T12, to which the ribs are attached. The x-ray showed alignment issues in the thoracic vertebrae. |
Define: Lumbar Vertebrae | The five larger vertebrae in the lower back, labeled L1 to L5, which support much of the body’s weight. She experienced pain in her lumbar vertebrae after lifting heavy boxes. |
Define: Sacrum | A triangular bone at the base of the spine, formed by the fusion of five vertebrae, connecting to the pelvis. The injury affected her sacrum, causing significant discomfort. |
Define: Coccyx | Also known as the tailbone, it is a small, triangular bone at the very base of the vertebral column. She experienced pain in her coccyx after a fall. |
Define: Pelvis (Hip Bone) | The bony structure at the base of the spine that connects the trunk to the lower limbs. The doctor assessed the pelvis for any fractures after the accident. |
Define: Ilium | The largest and uppermost part of the pelvis, forming the hip bone. The fracture was located in the ilium. |
Define: Ischium | The lower and back part of the hip bone, which supports the weight of the body when sitting. He felt pain in his ischium after sitting for a long time. |
