The human being skeleton has actually a variety of functions, such as protection and supporting weight. Different types of bones have differing shapes related to their specific function.

So, what space the different varieties of bones? just how are they categorized?
There are five types of skeleton in the skeleton: flat, long, short, irregular, and also sesamoid.
Let’s go with each form and check out examples.
1. Level Bones defend Internal Organs
There room flat bones in the skull (occipital, parietal, frontal, nasal, lacrimal, and vomer), the thoracic cage (sternum and ribs), and also the pelvis (ilium, ischium, and pubis). The role of level bones is to protect internal guts such together the brain, heart, and pelvic organs. Flat bones are somewhat flattened, and also can provide protection, favor a shield; level bones can also provide big areas of attachment for muscles.
2. Long Bones assistance Weight and also Facilitate Movement
The long bones, longer than they are wide, incorporate the femur (the longest bone in the body) as well as relatively small skeleton in the fingers. Long bones function to assistance the load of the body and also facilitate movement. Long bones are greatly located in the appendicular skeleton and also include skeletal in the reduced limbs (the tibia, fibula, femur, metatarsals, and phalanges) and bones in the top limbs (the humerus, radius, ulna, metacarpals, and also phalanges).
3. Short Bones are Cube-shaped
Short bones are about as lengthy as they are wide. Situated in the wrist and also ankle joints, brief bones administer stability and also some movement. The carpals in the wrist (scaphoid, lunate, triquetral, hamate, pisiform, capitate, trapezoid, and also trapezium) and also the tarsals in the ankles (calcaneus, talus, navicular, cuboid, lateral cuneiform, intermediate cuneiform, and also medial cuneiform) are instances of short bones.
4. Irregular skeleton Have complicated Shapes
Irregular bones differ in shape and structure and also therefore do not to the right into any type of other classification (flat, short, long, or sesamoid). They regularly have a fairly complex shape, i beg your pardon helps protect internal organs. Because that example, the vertebrae, irregular bones of the vertebral column, protect the spinal cord. The irregular skeletal of the pelvis (pubis, ilium, and ischium) safeguard organs in the pelvic cavity.

5. Sesamoid bones Reinforce Tendons
Sesamoid bones are bones embedded in tendons. These small, ring bones are commonly found in the tendons that the hands, knees, and feet. Sesamoid bones role to protect tendons indigenous stress and also wear. The patella, typically referred to as the kneecap, is an example of a sesamoid bone.
