Solution The correct option is Dhumerushumerus of arm corresponds to femur of leg.The human skeleton of an adult consists of around 206 bones, depending on the counting of sternum (which may alternatively be included as the manubrium, body of sternum, and the xiphoid process).[1] It is composed of 270 bones at the time of birth,[2] but later decreases to 206: 80 bones in the axial skeleton and 126 bones in the appendicular skeleton. Many small accessory bones, such as sesamoid bones, are not included in this count. Introduction[edit]As a person ages, some bones fuse, a process which typically lasts until sometime within the third decade of life. Therefore, the number of bones in an individual may be evaluated differently throughout a lifetime. In addition, the bones of the skull and face are counted as separate bones, despite being fused naturally. Some reliable sesamoid bones such as the pisiform are counted, while others, such as the hallux sesamoids, are not. Individuals may have more or fewer bones than the average (even accounting for developmental stage) owing to anatomical variations. The most common variations include sutural (wormian) bones, which are located along the sutural lines on the back of the skull, and sesamoid bones which develop within some tendons, mainly in the hands and feet. Some individuals may also have additional (i.e., supernumerary) cervical ribs or lumbar vertebrae. Amputations or other injuries may result in the loss of bones. Complete bone fractures may split one bone into multiple pieces. Other genetic conditions may result in abnormally higher (e.g. polydactyly or conjoined twins) or lower (e.g. oligodactyly) counts of bones. Bones[edit]The axial skeleton, comprising the spine, chest and head, contains 80 bones. The appendicular skeleton, comprising the arms and legs, including the shoulder and pelvic girdles, contains 126 bones, bringing the total for the entire skeleton to 206 bones. Spine (vertebral column)[edit]A fully grown adult features 26 bones in the spine, whereas a child can have 34.
Chest (thorax)[edit]Various bones of the human skeletal system. There are usually 25 bones in the chest but sometimes there can be additional cervical ribs in men. Cervical ribs occur naturally in other animals such as reptiles.
Skull[edit]There are 23 bones in the skull. Including the bones of the middle ear and the hyoid bone, the head contains 29 bones.
Upper limb (arm and forearm) and hand[edit]There are a total of 64 bones in the arms, 32 in each arm
Pelvis (pelvic girdle)[edit]The pelvis (or hip bone) is made up of three regions that have fused to form 2 coxal bones. They are: ilium, ischium, and pubis
Lower limb (thigh and leg) and foot[edit]There are a total of 60 bones in the legs.

What are the 4 arm bones?Your arm is made up of three bones: the upper arm bone (humerus) and two forearm bones (the ulna and the radius). The term "broken arm" may refer to a fracture in any of these bones.
What part of the skeleton is the arm bone?Humerus. The humerus is the long bone between the shoulder and the elbow. It has the ball of the ball and socket of the shoulder (glenohumeral) joint. At the other end, it has its portion of the elbow joint.
Which of the following is not a human bone?Detailed Solution. Axe is NOT a bone in the human body. Ear bone, also called Auditory Ossicle, any of the three tiny bones in the middle ear of all mammals. These are the hammer, anvil, and the stapes/stirrup.
