SKELETON
The human skeleton is the internal framework of the human body. It is composed of around 270 bones at birth – It decreases to around 206 bones by adulthood after some bones get fused together. The bone mass in the skeleton reaches maximum density around age 21.
Skeleton includes:
bones
cartilage
Skeleton forms:
supporting framework of body
Skeleton is designed for:
effective production of movements by attached muscles
Types:
1_Axial skeleton
2_Appendicular skeleton
These bones and cartilage are the type of connective tissue present in body.Connective tissues connect and support other body tissues.
The human skeleton is made up of 206 bones, including bones of the:
Skull – including the jaw bone.
Spine – cervical, thoracic and lumbar vertebrae, sacrum and tailbone (coccyx)
Chest – ribs and breastbone (sternum)
Arms – shoulder blade (scapula), collar bone (clavicle), humerus, radius and ulna.
Do YOU KNOW?
Teeth are not bones but are still part of the human skeletal system.
While the adult human skeletal system includes 206 bones, the infantile skeletal system has many more, since not all of the bones have fused together yet.
When humans moved into permanent settlements to farm, the human skeletal system weakened from the lack of rigorous exercise required for nomadic hunting and gathering.
REGIONS OF SKELETON
Axial skeleton:
Appendicular skeleton:
So these are total 206 bones in the adult human body
Do you know?
*Largest bone is FEMUR BONE
*Smallest bone is STAPES BONE (in ear ossicles)
*Most bones in the body are in HANDS
I have already written on SUBDIVISIONS OF ANATOMY .So if you want to start from basics , then you must know all these things to get good grip on basic knowledge.
Here is the link for subdivisions of Anatomy.Hope this helps.
