Bones grow widthwise through a process called appositional growth, which occurs at the periosteum, the outer layer of bone. Osteoblasts, cells responsible for bone formation, deposit new bone matrix on the outer surface, while osteoclasts resorb bone from the inner surface of the medullary cavity. This coordinated activity allows bones to increase in diameter while maintaining their shape and structural integrity. Additionally, the growth of the bone's width is also influenced by mechanical stress, which stimulates bone remodeling.
What else can I help you with?
Is it true that babies are born with 300 bones but by audlt hood they have 206?
That is true. Babies have bones that have not connected completely, to allow for room to grow.
What structures allow the infant head to be compressed during birth and accommodate brain growth in the fetus and infant?
Fontanelles, or "soft spots". These are features of the infant skull that have soft gaps between the cranial bones. They allow for rapid stretching and deformation, since the brain expands faster than the surrounding bone can grow.
Do dinosaurs grow bones?
yes they have to grow bones in order to grow from baby to adult
Do snakes grow bones as they age?
Snakes do not grow bones as they age; rather, they have a fixed number of bones in their bodies from birth. Their skeletons consist of many vertebrae (often over 200) and ribs, which allow for flexibility and movement. While snakes can grow in size and length as they molt and shed their skin, their bone structure remains unchanged throughout their lives.
Do moles grow on bones?
Moles only grow on skin, not on bones. Bones do have their own irregularities, but not moles.
What makes your bones grow?
Our bones grow on milk! If you didn't know... sadness
Does your bones stretch out when you grow older?
bones do not stretch; they grow by building more cells.
How many bones are there in a babies skull are held together by membranous regions?
There are six bones in a baby's skull that are connected by membranous regions called fontanelles. These fontanelles allow for some flexibility during childbirth and allow the skull to grow rapidly in the early years of life.
Where do bones go when you grow?
They expand as you grow.
What three bones never grow?
bones in ear
Do you get more bones as you grow older?
No, the number of bones in the human body remains the same as we grow older. A baby is born with about 270 bones, but many of these fuse together as the body matures, resulting in the adult skeleton of around 206 bones.
When you grow how many bones do you have?
206, although infants will have more - these extra bones will then fuse together as they grow.
