Bones of Human Body

The bones are a solid structure made up of calcium phosphate and collagen. Also, they are living tissues that grow. Furthermore, calcium hardens the framework and the combination of collagen and calcium makes bones strong and flexible to endure stress.

Most noteworthy, with time the bones merge into each other and that’s why at birth the infants have around 270 bones and when he grew up (At age 21) the number of bones decreases to 206 bones.

On average there are 206 bones in the human body. Besides, the bones in human body are classified into various categories.

Let us discuss the Bones in Human Body in greater detail –

1. Flat Bones

We refer to them as flat bones because they are flat in shape. Furthermore, the skull, thoracic cage, and the pelvis all are flat bones. Besides, they protect internal organs like the brain, pelvic organs, and heart.

In addition, they have a somewhat flat surface that acts as a protective shield. Moreover, they provide a large area for the attachment of a muscle.

2. Long Bones that support weight and Facilitate Movement

They are longer in shape than their width. Also, it includes the femur (the longest bone in the body). An important fact about femur is that it makes a quarter of your height and is as strong as concrete.

Moreover, long bones support the weight and movement of the body. These bones are mostly located in the appendicular skeleton and include bones of the lower limbs and bones of the upper limbs (Hand).

3. Short Bones

These bones are equally long and wide. Furthermore, we can locate them in ankle joints, and wrist. In addition, short bones provide stability and some movement to the body. Besides, the carpals of the wrist and the tarsals of the ankle are some examples of short bones.

4. Irregular Bones

These bones have a complex shape also due to their shape and structure they do not fit in any other category of bones in human body. Most noteworthy, they have a more complex shape than any other bone of the body due to which they are helpful in protecting internal organs.

Its example: the vertebral column is oddly shaped but it protects the spinal cord. Also, the irregular shape of the pelvic bone protects the organs of the pelvic cavity.

5. Sesamoid Bones Reinforce Tendons

These are the bones that are linked to the tendons. Besides, we can find these small and round bones commonly in the tendons of the keens, feet, and hands. Furthermore, their main function is to protect the tendons from wear and stress.

Most noteworthy, the patella, which we commonly refer to the kneecap, is also a sesamoid bone.
