It’s an interesting question that how many bones are in the? Here we will see in more detail each of the bones that shape our skeleton, this almost perfect structure that allows us to walk, run, stand up, after all, our structure of nourishment. The human skeleton composed of 270 bones at birth which decreases to 206 bones by later life after some bones have combined together. Normally human skeleton structure composed of 270 bones at birth, which decreases to 206 bones by adulthood after some bones have fused together Bones of the can be classified as the axial skeleton which consists of 80 bones and the appendicular skeleton which consists of 126 bones. The axial Skeleton which is the central core of the body while the appendicular skeleton which forms the limit of the arms and legs.
Primarily bones are divided into four major types described as
long bones, short bones, flat bones, and irregular bones.
Long bones differentiates from other types of bones. Long bones are made up mostly of compact bone, and have less marrow and spongy bone. Most upper and lower long bones are classified as long bones, among the exclusion of the bones in the wrist, ankle, and the patella in the knee.
Short bones are shaped respectively to a cube. Nothing like long bones, short bones contain a thin layer of compact bone, and are mostly filled with spongy bone. These short bones consist of the bones in the wrist and ankle, as well as sesamoid bones, including the patella. These short bones are not as hard as long bones because they have less compact bone and more softies bone which making them more inflexibility.
Flat bones have larger, flat surfaces. The main purpose of flat bones is to protect the body’s organs, and as a site for muscle attachment. This includes flat bones include the ribs, cranial bones of the skull along with bones of the shoulder girdle.
Bones that do not fall into the category of long, short, or flat are considered irregular bones. The shape, size, and composition of irregular bones vary. The backbone and some of the skull bones are irregular.
Functions of the bones of the
The functions of the skeleton are very diverse and among them we find:
Upholding and Maintenance of the position: It means we can stand, thanks to our skeleton system.
Active body: Bones along with other structures like muscles, ligaments and tendons let us to move in a proper way. So that we can do our day to day activities.
Protection: Some piece of the skeleton provides protections, as it is the case of the ribs.
Carry Metabolic: The bones function as a deposit of salts and other significant metabolites for the accurate meaning of the.
Now we got a comprehensive idea about the fact that our body structure can have about 206 bones, depending on the age of the individual, but, what are these bones that make up the? To make it easier we are trying to point out all the bones of the human being body depending on the areas which are given below in short.
Bones of the head (skull)
The head comprises of a total of 29 bones, counting the bones of the ear and the hyoid, a somewhat peculiar structure that is placed at the base of the tongue and is the one that allows us to speak and swallow. If we only count the skull, there are 22 bones.
Skull Bones: There are 8 bones in the skull
Face Bones: There are 14 bones in the face
Lower nasal turbinate: 2
Upper Jaw: 2
Lower jaw or mandible
Ear Bones: There are 6 bones in the ear
Stapes: 2 (it is the smallest bone in the, measuring about 3 mm)
Hyoids bone: There is only one.
Bones of the spine
Bones of Spine have 26 bones in overall
Cervical vertebrae: 7
Thoracic vertebrae: 12
Lumbar vertebrae: 5
Sacral vertebrae: 5 at birth, 5 at birth, then merge and form a single sacral vertebra, also known as Sacrum
Coccygeal vertebrae: 4 at birth, then merge into one, coccyx
Bones of the Arm
A total of 10 bones make up both arms.
Bones of the Hands
The hands have a total of 54 bones, 27 on each side.
Carpal bone (wrist): 16 bones
Metacarpus: 10 bones
Phalanges: 28 bones
Bones of the Thorax
Ribs: 12 pairs or 24
Bones of the Pelvis
The Pelvic Bones (2), which are the ones that form the hip, are formed by three regions:
Bones of the Legs
Femur: 2 (the longest bone in the, it can measure half a meter)
Bones of the Feet
The feet have a total of 52 bones, 26 on each foot.
Metatarsal bones: 10
Additionally to all the bones of our body, there are accessory bones, known as sesamoid bones. The largest sesamoid bone in the human being is the patella, but other parts are found, such as the lenticular bone located in the ear, the fabelas located in the knee, the pisiform bones located in the wrist. These are all the bones that we find in the. We hope that you now know how many bones the human being has. The construction of our bones is a complex process. Without bones, we would have no proper frame for our skeleton, be not capable to move our skeleton, leave our internal organs poorly protected, lack of blood and be petite on calcium.
