Introduction to Bones in Human Body

Hey, do you remember the “Grim Reaper” from the show “Grim Adventure of Billy and Mandy”? He was essentially not a human, rather a talking skeleton. The skeleton is the inner hard structure of our body and is made of a number of bones. Bones are solid structures made up of proteins and minerals and provide a shape to the body. They act as a protective layer for all the internal organs such as the brain, heart, lungs, etc and they are known to give support to the organs within the body and also anchor muscles.


Types of Bones in the Human Body

There are a  variety of bones found in our body and can be of multiple sizes and shapes.

There are 4 major types of bones in our body, i.e. long, short, flat, and irregular.


Long Bones

  • These bones have a much greater length than width and hence are called long bones. 

  • They can be described as a  long shaft almost like a rod with two bulky ends looking like a dumbbell.

  • They are mostly very solid but might have a large number of spongy portions in them at both ends. 

  • The bones of the thigh, leg, arm, and forearm are all long bones. 


Short Bones

  • These bones are cube-shaped with almost equal length and breadth.

  • These bones are primarily spongy and covered with a thin layer of compact bone. 

  • The bones present in the wrist and ankle are the short bones.


Flat Bones

  • These bones do not have much volume and are essentially flat and thin and also curved. 

  • Cranium is made up of flat bones.


Irregular Bones 

  • These are the bones that do not have a specific shape in order to classify them into any of the above groups. 

  • These are the spongy bones that are covered by a thin layer of compact bone. 

  • Bones of the vertebrae and some skull bones are all irregular bones.

List of Human Bones

  • Humans have a total of 206 bones in their bodies. 

  • There are many groups of bones in the human body. 

  • Many parts of our skeleton are made up of multiple small bones joined together to form a proper structure. 

  • The various groups include,

Function of Bones

  • They provide structural support to the body. 

  • The bones joined at different locations allow various movements. 

  • They are known to protect various vital organs such as the rib cage protects the heart and lungs.

  • The blood in our body is formed within the bones by the bone marrow or specifically the red marrow. 

  • The bones are also important for storage of minerals such as calcium and phosphorus. 


Summary

Bones are the framework of the body which is important to stand erect and help to protect different delicate organs. The largest and strongest bone is the femur or thigh bone. The bones won’t grow after puberty, the density and strength change over time.

FAQs on Bones Names

1. What are the different bones in the human skeleton?

There are 206 bones in all in the human body.

The human body is made up of numerous different bone groupings.

Numerous small bones are linked together to generate larger bones in many places of our skeleton.

among the numerous groups are,

  1. Facial bones

  2. Ear bones

  3. Throat bone

  4. Shoulder bones

  5. Thorax bones

  6. Vertebral column 

  7. Upper arm bones

  8. Forearm bones

  9.  Hand bones

  10.  Wrist bones

  11.  Palm bones

  12.  Finger bones 

  13.  Pelvis bones

  14.  Leg bones 

  15.  Feet bones 

  16.  Toe bones

  17.  Cranial bones

2. Define the long bones?

These bones are referred to as long bones because their length exceeds their width by a wide margin. They can be described as having a long, nearly rod-like shaft and two hefty ends that resemble dumbbells. Although they may contain a significant amount of spongy areas at both ends, they are generally fairly solid. Long bones include those in the thigh, leg, arm, and forearm. These bones have a much greater length than width and hence are called long bones. 

3. What is the function of bone?

Different movements are possible due to the bones' numerous points of joining. The red marrow in particular, found in the bone marrow, is responsible for producing the blood in our bodies. They give the body structural support. The rib cage is known to protect the heart and lungs, among other essential organs. Minerals like calcium and phosphorus are crucial to store in the bones.
