The ends of our long bones fit into joints. These joints are lined with cartilage (the flexible tissue that makes up your ears and nose), because cartilage is smoother than bone, and allows the joint to move better

But cartilage isn't as strong as bone. By having a larger surface area at the bone end, the stresses on the cartilage are spread out over a greater area. (think of how it would take much less force to break the skin with a pin than with a pencil).

True or false long bones grow in length after birth by producing new bone tissue in the middle of the diaphysis?

True. Long bones are able to grow in length after birth through a process called endochondral ossification, where new bone tissue is produced in the middle of the diaphysis at the epiphyseal plate. This growth continues until the growth plates close at the end of puberty.


What type of cartilage covers the end of bones?

hyaline cartilage is present in the end of long bones.


Distal and proximal ends of long bones?

The distal end of a long bone is the end farthest from the center of the body, while the proximal end is the end closest to the body's center. These ends are important for articulating with other bones and facilitating movement at joints.


What are the long hand bones proximal to the phalanges?

The long hand bones proximal to the phalanges are the metacarpals. They articulate with the carpals of the wrist at one end and the phalanges of the fingers at the other end. There are five metacarpal bones in each hand.


What are the small bones called that make up the spine?

This is a tricky question as it is not clear which end of the spine we are referring to. At the head end there is a bone or vertebra upon which the head is resting this is known as the atlas, it does not have a body and its centrum fuses with the axis to provide a pivot for the head to turn on. At the other end of the spine - the tail end the last bones are fused together to form the coccyx, the number may vary from 3 to 5. These bones are rudimanetary and are usually fused together.
