Fontanelle is the name for the soft tissue "spaces" between the bones of the skull in babies and infants under the age of two. These areas of soft tissue (although actually strong and tough) enable the infant skull to more easily pass through the birth canal since they allow the bony skull plates to move and reshape slightly as needed during the birth process. These are also commonly called "soft spots" in babies. These areas ossifyto become bone tissue around the childhood age of two, and then gradually over a person's life connect more and more tightly with the adjoining skull plates, forming the cohesive skull. They would then be called "sutures" of the skull instead of fontanelles. The sutures continue to "knit" or heal together with each other throughout a persons life until after the age of 50 when they are usually fully knit. However, in some people some of the sutures, especially the parietal, never do become totally knit. This understanding of the closing process of the fontanelles and knitting of the sutures is helpful in the sciences of forensics and archeology to determine the age at death when skeletons are scientifically studied post mortem.

What are bones that lack a long axis and have a somewhat irregular shape?
Irregular bones are bones that lack a long axis and have a non-uniform shape. They include bones such as the vertebrae in the spine, facial bones, and hip bones. These bones provide support and protection for various organs and tissues within the body.
What are cavities with spaces within joints called?
Cavities with spaces within joints are called synovial cavities. These are found in synovial joints, which are characterized by a fluid-filled space that allows for smooth movement between the articulating bones. The synovial fluid within these cavities acts as a lubricant, reducing friction and providing nourishment to the cartilage. Examples of synovial joints include the knee, elbow, and hip joints.
What are 7 irregular bones in the neck?
Cervical vertebrae
Where does spongy bone occur in the skeleton?
Spongy bone, also known as trabecular bone, is found at the ends of long bones within the epiphysis and in the interior of flat and irregular bones. It provides structural support while also being lightweight, making it ideal for spaces needing flexibility and some strength.
Examples of bones according to its shape and size?
Examples of long bones are the femur in the thigh and the humerus in the upper arm. Flat bones include the skull and the sternum. Short bones are found in the wrist (carpals) and ankle (tarsals). Irregular bones like the vertebrae in the spine and the hip bones have complex shapes.
What is FILLED WITH MARROW AND HAS AIR SPACES TO MAKE IT LIGHT?
The answer is bones. Bones are filled with marrow and have air spaces to make them lighter in weight.
What are the spaces of cartilage bone filled with?
the bones are filled with bone marrow
The spaces in the bones are filled with a soft connective tissue called?
cartilage because i am the smart one and you aren't
Which animal's bones are filled with air spaces?
Birds.
What is air filled space in the bone?
Air-filled spaces in bones are called sinuses. These are hollow cavities within the bones that help to reduce the bone's weight while maintaining strength. The most well-known sinuses are the paranasal sinuses, found in the skull bones surrounding the nasal cavity.
Type of bone that contains air spaces?
The type of bone that contains air spaces is called spongy or cancellous bone. This type of bone is less dense than compact bone and is characterized by a mesh-like structure that provides support while making bones lighter. Spongy bone is primarily found at the ends of long bones and in the interior of flat bones.
What are spaces in bones that are filled with a soft connective tissue called?
Soft connective tissue found inside some bones is? Hi.
Are their irregular bones or round bones?
There are irregular bones, these bones are your vertebrae
What are the spaces in the bones of the skull called?
sinuses
What are filled with a substance called marrow?
bones
What are spongy bones filled with in their small open spaces?
Bone marrow, more specifically yellow bone marrow.
What is a lightweight bone filled with spaces?
A lightweight bone filled with spaces is likely to be a cancellous or spongy bone. This type of bone tissue has a honeycomb-like structure with many small cavities that are filled with bone marrow. Cancellous bone is found at the ends of long bones and in the interior of flat bones.
