Osseous system

The skeletal system is a very resistant structure, perhaps the strongest in the body, which has important functions in the human body and in any other living being.

One of its relevant functions is to shape the human body and keep it upright according to its disposition and motor abilities.

Characteristics

In other words, we can say that the bone system is the skeleton as such. They are each of the 206 bones that make up an adult human body and are interconnected through tendons .

Although they are one of the strongest and most durable structures, bones also suffer the degradation that age or certain early diseases give. They can also break with sudden movements or collisions with strong objects, but like other elements in the body they can regenerate little by little.

Examples of bones of the skeletal system

  • Femur . It is the longest bone in the human body. It is located at the top of the leg.
  • Humeral . It is the bone that joins the elbow with the shoulder.
  • Ulna . It is one of the two bones (the longest) that join the elbow with the hand.
  • Tibia . It is unique to the femur by a joint, so it is located in the lower leg, next to the fibula.
  • I fibula . Joins the foot with the femur. It is a thinner and outer bone than the tibia.
  • Tarsus . They are the various bones that make up the heel of the foot: calcareous, talus, cuboid, navicular, and wedges.
  • Carpus. They are the bones of the wrist and the anterior area of ​​the hand: scaphoid, trapezium, trapezoid, large, hamate, lunate, pyramidal, pisiform.
  • Kneecap . It is located in the front of the knee, and unlike others, it is not that hard, in fact, it is somewhat spongy. It is shaped like a triangle.
  • Malar bone . It is located in the outermost part of the face.
  • Nasal bone. It shapes the nose (it is the “bridge” of the nose).
  • Scapula . It has a flat, triangular and wide shape. It is close to the lungs in the back. The clavicles like the humerus articulate with it.
  • Occipital . Located on the bottom and back of the head, near the nape of the neck.
  • Ilion . It is the largest bone in the pelvis, so it is the one that shapes the waist along with the ischium and pubis, in addition, it connects the spine with the legs.
  • Parietals . It is located in the skull, between the frontal and the occipital, and has a square shape.
  • Front . It is located right on the forehead.
  • Vertrebrae . Located in the center of the back. They are responsible for keeping us upright most of the time. In addition, they protect our spinal cord.
  • Hyoid . It is shaped like a “U” and is located in the neck, under the tongue and before the thyroid gland.
  • Temporary . It is even. It is in the lower, middle and lateral part of the human skull.
  • Bones of the ear. These are three bones: anvil, stirrup and hammer, and they are part of the eardrum.
  • Unguis or lacrimal bone. We find it on the face, just below the front. It is shaped like a fingernail.
