Explanation:
The human skeletal system is not quite as simple as the popular children's song suggests. The "head bone" (actually made up of 22 separate bones) is not connected to the "neck bone," but rather to a series of small bones that go all the way down the back. And the "toe bone" is actually made up of several bones that connect to another set of bones that provide structure for the foot. In total, the human skeleton consists of a whopping 206 bones.
In addition to all those bones, the human skeletal system includes a network of tendons, ligaments and cartilage that connect the bones together. The skeletal system provides the structural support for the human body and protects our organs. Our bones also serve several other vital functions, including producing blood cells and storing and releasing fats and minerals, according to the online textbook "Anatomy & Physiology" (BC Campus Open Textbooks).
Development and structure of the skeleton
Infants are born with about 300 separate bones, according to Nemours, a nonprofit children's health provider. As a child grows, some of those bones fuse together until growth stops, typically by the age of 25, leaving the skeleton with 206 bones.
Our bones are separated into two categories based on the purpose and location of the bones: The axial skeleton and the appendicular skeleton, according to "Anatomy & Physiology."
The axial skeleton contains 80 bones, including the skull, spine and rib cage. It forms the central structure of the skeleton, with the function of protecting the brain, spinal cord, heart and lungs.
The remaining 126 bones make up the appendicular skeleton; they include the arms, legs, shoulder girdle and pelvic girdle. The lower portion of the appendicular skeleton protects the major organs associated with digestion and reproduction and provides stability when a person is walking or running. The upper portion allows for a greater range of motion when lifting and carrying objects.
Bones are further classified by their shape: long, short, flat, irregular or sesamoid, according to "Anatomy & Physiology".
Long bones are found in the arms, legs, fingers and toes. These bones are longer than they are wide and are cylindrical. They move when the muscles around them contract, and they are the most mobile parts of the skeleton.
Short bones are found in the wrists and ankles and are about equal in their length, width and thickness.
Flat bones make up the skull, shoulder blades, sternum and ribs. These curved, thin bones protect internal organs and provide an anchor for muscles.
Irregular bones are those in the spinal cord and face, which, because of their unique dimension, don't fit in any of the other shape categories.
Sesamoid bones are found in the hands, wrists, feet, ears and knees. These small, round bones are embedded in tendons and protect them from the great pressure and force they encounter.
There are some variations between male and female skeletons. For example, the female pelvis is typically more broad, thin, and round than the male pelvis, according to "Anatomy & Physiology." [Image Gallery: The BioDigital Human]
Answer:
The different part of the human skeleton system are:-
1. Skull - It is a bony structure that surrounds the brain. The skull protect our brain.
2. Rib Cage - It is a cage- like structure consisting of 12 pairs of flat, thin and curved bones. The Rib Cage protect our lungs and heart.
3. Backbone or Spine - It act as a supporting rod.
4. Limbs - It allow to perform various movement and work. It also help us to lift the things.
Explanation:
The bones in our body make a Framework called the Skeleton it provide shape and structure to our body.
