Long Bones
Long bones are a few of the longest skeleton in the body, such as the Femur, Hummers and Tibia but are as well some of the smallest counting the Metacarpals, Metatarsals and Phalanges. The category of a long bone includes having a body which is longer than it is broad, with growth plates (epiphysis) at either conclusion, having a tough outer surface of reduce bone and a spongy inner call an cancellers bone contain bone marrow. Both ends of the bone are sheltered in hyaline cartilage to assist care for the bone and aid shock absorption.
Short Bones
Short bones be defined as being concerning as broad as they are extended and have a primary function of providing sustain and stability with small movement. Example of short bones is the Carpals and Tarsal’s in the wrists and foot. They include of merely a lean layer of reduce, tough bone with chancellors’ bone on the interior along with relatively gargantuan amounts of bone marrow.
Flat Bones
Flat bones are as they sound, powerful, flat plates of bone with the major function of providing safety to the body’s ultimate organs and being a base for muscular attachment. The typical example of a flat bone is the Scapula (shoulder blade). The Sternum (breast bone), skull (skull), Pelvis and Ribs are also off the record as flat bones. Anterior and subsequent surfaces are created of condense bone to supply potency for safety with the middle consisting of chancellors’ (spongy) bone and varying amounts of bone marrow. In adults, the maximum numbers of ruddy blood cells are created in flat bones.
Irregular Bones
These are bones which do not drop into any other classification, due to their non-uniform shape. Fine examples of these are the Vertebrae, Sacrum and Mandible (lower jaw). They primarily include of chancellors’ bone, with a lean outer layer of reduce bone.
Sesamoid Bones
Sesamoid frame are generally short or uneven bones, imbedded in a sinew. The most apparent example of this is the Patella (knee cap) which sits within the Patella or Quadriceps tendon. Other sesamoid bones are the Pisiform (smallest of the Carpals) and the twain little bones at the base of the 1st Metatarsal. Sesamoid bones are generally present in a tendon where it passes above a joint which serves to preserve the tendon.
