sesmoid
Those found inside tendons, like the patella and fabella
Flat bones, Short bones,Long bones, irregular bones and sesmoid bones
There are 5 types of bones in the human body. There are long bones, short bones, flat bones, irregular bones, and sesmoid bones.
There are 5 kinds of bones in the human body. They are: long, short, flat, irregular and sesmoid. 206 bones in adults. 300-350 in infants.
your lungs and skin
The body consists of long bones, flat bones, irregular bones, short bones and sesmoid bones. The short bones include bones in the wrist and foot.
The prehallux is a free-floating bone(a sesmoid bone) that is present in the ankles and wrists, which is very vital in organism movements because joints that are formed with a prehallux are less-restrictive in movement and therefore the organism can freely move or locomote freely without difficulties.
Patelle
Bones often don't hurt at first because your body shuts the pain out in the shock of it all. After while a small bone would hurt the least because there are fewer nerves damaged. Perhaps the small finger in the hand you use least or the toes.
There are 8 small bones in wrist joint.Proximalrow contains (From lateral to medial side.) ScaphoidLunateTriquartal and Pisiform bones. Except Pisiform other three are attached to lower end of 'Radius' bone. Please note that in 'elbow' joint Ulna bone takes part and in wrist joint charge is handed over to Radius bone. Distal row contains Trapezium, Trapezoid, Capitate and Ham-mate. So if you ask about the single bone, then the answer is Radius and not Ulna bone. But please remember that 'single' bone can not form a joint. There has to be at-least two bones. Here lower end of Radius comes in contact with three bones. Scaphoid, Lunate and Triquartal bones. Pisiform is a sesmoid bone. On distal side there are carpal-metacarpal joints. There are 5 metacarpals attached to four carpal bones.
It is the lower end of the radius bone taking part in wrist joint. Actually three bones are attached to radius bone. Scaphoid, Lunate, Triquartal. Forth Pisiform is a sesmoid bone. So you require first row of small bones, so that movement should be possible between radius and bones. With single bone attached to radius movement would have been restricted. Next row of four bones is attached in order to have more mobility to the metacarpals in one hand and proximal row of bones in other hand. It is possible to have four bones attached to proximal row to expand the area of movement. Here again with single long bone, movements have been restricted. As you have to support five fingers there should have been five small bones. But 'Nature' found it prudent to attach four bones to proximal three bones and attach five metatarsals to distal carpal bones. Here joint has to be flat and so many carpal bones are there. Here you have flex-ion, extension, adduction, abduction and circumduction. This joint is one of the architectural marvel by 'Nature'.
