Explanation:
Here are the parts of the skeletal system together with their corresponding definition.
1. Skull
- The skull is a bone structure that forms the head in vertebrates. It supports the structures of the face and provides a protective cavity for the brain.
2. Femur Upper Leg Bone
- The longest bone in the body. The femur articulates proximally with the acetabulum of the pelvis to form the hip joint, and distally with the tibia and patella to form the knee joint.
3. Shoulder Joint
- The shoulder joint is formed where the humerus (upper arm bone) fits into the scapula (shoulder blade), like a ball and socket.
4. Rib Cage
- The ribs are the bony framework of the thoracic cavity. The ribs form the main structure of the thoracic cage protecting the thoracic organs, however, their main function is to aid respiration.
5. Patella Knee Cap
- The patella, also known as the kneecap, is a flat, rounded triangular bone that articulates with the femur (thigh bone) and covers and protects the anterior articular surface of the knee joint.
6. Spine
- The spine or backbone is your body's central support structure. It connects different parts of your musculoskeletal system. Your spine helps you sit, stand, walk, twist and bend.
7. Clavicle Collar Bone
- Curved anterior bone of the shoulder (pectoral) girdle in vertebrates; it functions as a strut to support the shoulder. The clavicle is present in mammals with prehensile forelimbs and in bats, and it is absent in sea mammals and those adapted for running.
8. Pelvis
- Pelvis, also called bony pelvis or pelvic girdle, in human anatomy, a basin-shaped complex of bones that connects the trunk and the legs, supports and balances the trunk, and contains and supports the intestines, the urinary bladder, and the internal sex organs.
9. Metatarsals/ Foot Bones
- The metatarsal bones are the bones of the forefoot that connect the distal aspects of the cuneiform (medial, intermediate, and lateral) bones and cuboid bone to the base of the five phalanges of the foot.
10. Fibula
- The outer of two bones of the lower leg or hind limb, presumably so named because the inner bone, the tibia, and the fibula together resemble an ancient brooch or pin.
11. Tibia
- The tibia is also called the shin is the inner and larger of the two bones of the lower leg in vertebrates—the other is the fibula.
12. Humerus / Upper Arm Bone
- The humerus is the bone in your upper arm. It's located between your elbow and your shoulder and consists of several parts that allow it to move freely in different directions.
13. Radius
- The radius is one of the two bones that make up the forearm, the other being the ulna. It forms the radio-carpel joint at the wrist and the radio-ulnar joint at the elbow. It is the smaller of the two bones.
14. Ulna
- The ulna is one of two bones that make up the forearm, the other being the radius. It forms the elbow joint with the humerus and also articulates with the radius both proximally and distally.
15. Metacarpals / Hand Bones
- Metacarpals are flat at the back of the hand and bowed on the palmar side; they form a longitudinal arch that accommodates the muscles, tendons, and nerves of the palm.
