Question

Define long bones where do we find them in the human body?

Answer 1

Hint: The bones present in the thighs in the body are considered to be the longest bones in the body. The bones present in thighs are called femur bones and are cylindrical bones with spherical ends. The upper end of bone is attached into the socket of hips and lower is attached to the kneecap and it is lower towards the leg bones.

Complete answer:
Long bones are only located in the thigh area and they are similar in length and also in width. Bone contains marrow inside them, the bone marrow is of two types- yellow bone marrow and red bone marrow.
As we know, bones provide mobility and strength to the body and are the main sources of structural support. Bones are typically of five types- long, short, flat, Irregular and sigmoid. The femur and tibia perform crucial mobility in the body.
The growth of bone depends upon the diaphysis, which is elongation of bone and epiphysis, which is the growth of the bone. The longitudinal growth of bones is done by endochondral ossification. Bone growth is also related to hormones which helps in the regulation of bones. It is stimulated by growth hormones, secreted from the anterior lobe of the pituitary gland.
Long bones like- femora, tibiae, fibulae and radii, ulna. Other primary components like-vertebrae and skull. The outside layer of bone called periosteum is the compact bone and the layer will have a deeper layer named- cancellous bone which contains the medullary cavity.

Note:
There are disorders of bones such as rachitis fetalis and epiphyses in which bones become enlarged more than their usual size. Another disorder like-fetalis micro melica is known to be shortness in the length of bone. There are surgeries to rectify the bone diseases like- distraction osteogenesis.
