How many bones in the human body? This commonly asked question is a required knowledge for the students who have been taking human biology related courses. There are almost 206 bones found in a complete adult human body. However, the number of bones may vary from people to people with various un-named bones that have been developed in high friction parts of the body. Bones are made of collagen and calcium phosphate.
What is the function of the Human Skeleton?
Basically there are five functions that human skeleton system supports in the body, these are as following:
It is the main function of human skeleton, the shape changes as a human being grows. It also helps us in determining the height and size of our hands and feet. The stability in shape of our body enables so many other essential functions. For example stable bones in rib cage and spinal cord allows the lungs to function properly
After the muscles found in body, bones or skeleton system help keeping internal organs in right place. The strongest bones of pelvis, spinal cord and legs help a human being in standing by supporting the weight of a whole body. Besides that, the bones generally create a hollow space in which the vital organs are being framed like brain, heart, lungs, digestive system, urinary tracts and reproductive system.
The bones are joined together with the help of ligaments and tendons attach the muscle to the bones. Bones and muscles both working together are known as muscular-skeletal system. This system allows the body to have smoother and stable body movement and also keep our body in good position.
For example the leg bones are joined together at knees and can create movement by going back and forth.
The skeletal system protects the vital organs and prevents them from any massive damage by covering them. Remember bones are the living tissues with hard cells. Although the cells are hard and strong they are also bit flexible so that the fracture is prevented. The strength of bones comes from minerals known as Calcium and Phosphorus. The most important bones example in protection is the skull, ribcage and spinal cord bones.
Production of Blood cells
Big bones possess bone marrow, a sponge like tissues inside the bones. There are two types of bone marrow cells:
· Red bone marrow
Red bone marrow cells are responsible in producing the red blood cells and also white blood cells. The red blood cells production in a healthy person is almost 200 million cells per day.
· Yellow bone marrow
Yellow bone marrow possesses primary fat cells and can also transform itself into red marrow in times of need like in case of anemia.
How many bones does a baby have?
New born babies possess 305 bones. Surprisingly, the baby’s skeleton system is made of cartilage. As person grows older, the cartilage gradually turns into bones. This process is known as ossification. An adult person will have 206 bones.
How many muscles are in
the human body?
Some textbooks of anatomy suggest that human body contain 640 muscles while others say there are 639 muscles. The muscular system is composed of fibers and tissues. Muscles are responsible for smooth movement of the body.
Number of bones in human body male vs. female
The only vivid difference in male and female skeletal system is that females contain a round pelvis region than men. Besides that, there is no difference including the number of bones in the skeletal system.
How many bones are in the human skull?
Human skull has 22 bones, eight cranial bones and 14 facial bones.
What are the names of 14 facial bones?
If you are wondering how many facial bones are there? So the answer to this is there are 14 facial bones. Their names and their numbers are as follows:
- Nasal bones (2)
- Zygomatic (2)
- Maxila (2)
- Mandible (1)
- Lacrimal (2)
- Palatine (2)
- Inferior nasal conchae (2)
- Vomer bone(1)
What is the cranium and what does it do?
Cranium region is found in the skull. The primary function of cranium is protection of the brain from any injury. Furthermore, cranium is composed of 8 different kinds of bones that grow together. The areas where these bones attach are known as sutures.
How many bones in the foot?

What are long bones in the body?
Long bone is that category of bones which is classified mainly because of its shape and not size. Long bone has
- Largely cylindrical shaft that is longer than wide
- Slightly curved
- Has two ends that are typically expanded
Long bones facilitate the movement and also support the body weight. Bones in upper and lower limbs are considered long bones.
So have you ever wondered what are the bones in the body? And how many bones in the human body? Well bones are living and growing tissues. Bone is mostly made of collagen. Collagen is a protein that gives bone a soft framework whereas calcium phosphate (a mineral) that adds up strength in the bone. Bones facilitate the movement in the body and also support the body weight. There are almost 206 bones in an adult human being (both male and female). Babies have 305 bones that are made of cartilage.
