The human being skeleton has a number of functions, such together protection and also supporting weight. Different species of bones have differing shapes related to their details function.

You are watching: Which of the following is a sesamoid bone?

So, what room the different types of bones? how are castle categorized?

There room five varieties of bones in the skeleton: flat, long, short, irregular, and sesamoid.

Let’s go v each type and view examples.

1. Level Bones safeguard Internal Organs


There are flat bones in the skull (occipital, parietal, frontal, nasal, lacrimal, and also vomer), the thoracic cage (sternum and ribs), and the pelvis (ilium, ischium, and also pubis). The role of flat bones is to defend internal guts such together the brain, heart, and also pelvic organs. Level bones are rather flattened, and also can carry out protection, like a shield; level bones can also provide large areas of attachment because that muscles.

2. Lengthy Bones assistance Weight and also Facilitate Movement


The long bones, longer than they space wide, include the femur (the longest bone in the body) too as reasonably small skeletal in the fingers. Lengthy bones duty to assistance the load of the body and facilitate movement. Long bones are greatly located in the appendicular skeleton and include bones in the lower limbs (the tibia, fibula, femur, metatarsals, and phalanges) and also bones in the upper limbs (the humerus, radius, ulna, metacarpals, and also phalanges).

3. Brief Bones space Cube-shaped


Short bones are about as lengthy as they room wide. Located in the wrist and ankle joints, brief bones carry out stability and some movement. The carpals in the wrist (scaphoid, lunate, triquetral, hamate, pisiform, capitate, trapezoid, and trapezium) and also the tarsals in the ankles (calcaneus, talus, navicular, cuboid, lateral cuneiform, intermediary cuneiform, and also medial cuneiform) are instances of quick bones.

4. Irregular skeleton Have complex Shapes


Irregular bones vary in shape and also structure and also therefore execute not to the right into any type of other category (flat, short, long, or sesamoid). They often have a fairly facility shape, i m sorry helps safeguard internal organs. For example, the vertebrae, irregular skeleton of the vertebral column, safeguard the spinal cord. The irregular bones of the pelvis (pubis, ilium, and ischium) protect organs in the pelvic cavity.

5. Sesamoid skeletal Reinforce Tendons


Sesamoid bones room bones installed in tendons. These small, round bones are typically found in the tendons that the hands, knees, and feet. Sesamoid bones duty to protect tendons from stress and wear. The patella, typically referred to as the kneecap, is an instance of a sesamoid bone.
