Chicken bones are made up of compact bones and spongy bones. The compact bone forms the outer layer, while the spongy bone is the inner bone. Spongy bone is softer than compact bone and contains many hollow spaces, which help prevent the bone from breaking by acting as shock absorbers. The compact bone is cream-coloured, while the spongy bone is reddish in colour.

What You'll Learn
The colour of spongy bone is reddish
In chickens, the spongy bone is surrounded by compact bone, which forms the outer layer. The compact bone is dense and hard to compress, while the spongy bone is softer and more flexible. This combination of compact and spongy bone allows for a strong yet lightweight skeletal structure, which is essential for flight.
The reddish colour of spongy bone is due to its unique composition. Spongy bone is made up of thin cells called trabeculae, which are separated by spaces called lacunae. These spaces are filled with blood vessels and connective tissue, giving the bone its characteristic colour.
The microstructure of spongy bone can vary depending on various influences, such as the levels of hormones and chemicals like calcium and phosphorus. For example, young chickens are sensitive to vitamin D deficiency, which can affect calcium levels and bone development.
Overall, the reddish colour of spongy bone is an important aspect of its structure and function, contributing to the strength and flexibility of the skeletal system in chickens and other animals.

Spongy bone is surrounded by compact bone
Bones are made up of both living and non-living material. There are two types of bone tissue: compact and spongy. Compact bone forms the hard outer layer of the bone, while spongy bone forms the porous interior. Spongy bone is softer than compact bone and contains many hollow spaces. These spaces help prevent the bone from breaking, acting as shock absorbers when the bone is hit or banged.
In birds, much of the bone is laid down in successive layers to form dense, compact bone covered by the cellular periosteum on the outside. The periosteum is a membrane that covers the outside of the bone, except in regions covered with articular cartilage. Underneath the periosteum is a layer of compact bone, followed by spongy bone. This structure is observed in flat bones, such as those of the cranium, which consist of two layers of compact bone surrounding a layer of spongy bone.
Spongy bone, also known as cancellous bone, is composed of a lattice-like arrangement of osteocytes called trabeculae. These trabeculae form a mesh-like network of bony spicules that vary in size and align along regions of biomechanical stress. They project into the medullary cavity from the internal circumferential lamellae of the cortical bone. The medullary cavity contains red bone marrow, which supplies osteocytes with blood and aids in removing waste products.
The two layers of compact bone and the interior spongy bone work together to protect the internal organs. For example, in the cranium, if the outer layer of compact bone fractures, the brain is still protected by the intact inner layer of compact bone and the spongy bone beneath it. This layered structure provides a combination of strength and shock absorption, contributing to the overall protection and functionality of the skeletal system.

Spongy bone is softer than compact bone
The skeletal system of a chicken leg consists of bones, muscles, skin, ligaments, tendons, and cartilage tissue. The bones of a chicken leg include the tibia, fibula, and femur. The tibia is a longer and thicker bone compared to the fibula. The upper leg bone, or the thigh, is called the femur, similar to humans.
Chicken bones, like all bones, are composed of both living and non-living material. A typical long bone is enlarged at both ends with a shaft in between. A membrane called the periosteum covers the bone, and under that layer is compact bone. Beneath the compact bone is a material called spongy bone, which is softer and less dense than compact bone. Spongy bone contains many hollow spaces that act as shock absorbers, preventing the bone from breaking when hit or banged. This type of bone is most commonly found at the ends of long bones.
The microstructure of bones is dynamic and influenced by various factors, including chemicals such as calcium and phosphorus, and hormones like growth hormone and parathyroid hormone. For example, young chickens are susceptible to vitamin D deficiency, which can lead to calcium deficiency and rickets.
During embryo development, chicken bones go through a membranous stage, a cartilaginous stage, and an ossification stage. The ossification process hardens the cartilage by depositing minerals, primarily calcium carbonate, which gives bones their hardness. However, when a chicken bone is soaked in vinegar, the acid removes the calcium, making the bone spongy, rubbery, and flexible. This experiment demonstrates the softer nature of spongy bone compared to compact bone, as the bone becomes bendable without breaking.
In terms of color, the raw bone of a chicken leg is lighter in color compared to the darker baked bone. The articular cartilage is white and smooth, while the tendon is a pearly white color. The bone marrow is red, and the spongy bone has tiny holes, resembling a sponge.

Spongy bone contains pockets of air
The chicken leg bone is made up of compact bone and spongy bone. Spongy bone, also known as cancellous bone, is a type of bone tissue that has a porous structure with numerous large spaces, giving it a honeycombed or spongy appearance. These spaces are filled with bone marrow, which produces the body's blood cells, and blood vessels.
The spongy bone in chicken legs is red in colour and has tiny holes, resembling a sponge. This type of bone is softer and more lightweight than compact bone due to its many hollow spaces. These spaces act as shock absorbers, helping to prevent the bone from breaking when subjected to impact. Spongy bone is also more easily remodelled than compact bone, allowing it to accommodate the changing needs of the body.
In the chicken skull, the cranial external appearance suggests a larger brain capacity than is actually the case. This is because the skull bone is formed by two layers of dense bone separated by a layer of spongy bone. The spongy bone in the skull contains pockets of air derived from the Eustachian tubes, which connect the upper respiratory system with the middle ear. These air pockets form part of the tympanic cavities, where the eardrum is located.
The colour and properties of chicken bones can be altered by subjecting them to various treatments. For example, when a chicken bone is soaked in vinegar, the acid removes the calcium, resulting in a spongy, rubbery, and flexible bone that does not break under pressure. In contrast, baking a chicken bone in an oven for two hours causes it to become fragile and brittle, easily breaking into many small pieces.

Bones are a type of body tissue
Bone tissue, or osseous tissue, has a honeycomb-like matrix internally, which gives bones their rigidity. This tissue is made up of different types of bone cells, primarily osteoblasts and osteocytes, which are involved in the formation and mineralisation of bone, and osteoclasts, which are involved in the resorption of bone tissue.
Bone tissue is mineralised and has both organic and inorganic components. The organic component is made up mainly of collagen, specifically type I collagen, called ossein, which provides flexibility to the bone. The inorganic component is made up of various salts and bone minerals, primarily hydroxyapatite, calcium, and phosphorus.
Bone tissue is constantly changing through a process called remodelling, where osteoblasts create new bone tissue, osteoclasts break down and reabsorb old bone tissue, and osteocytes direct this process. This process is influenced by factors such as exercise, age, and the levels of certain hormones in the blood.
The colour of spongy bone in a chicken leg is red, and it has tiny holes like a sponge. Spongy bone, also known as cancellous bone, is softer than compact bone and contains many hollow spaces that act as shock absorbers to prevent the bone from breaking. In chickens, the cranium is formed by two layers of dense bone separated by a layer of spongy bone, which contains pockets of air derived from the Eustachian tubes that connect the upper respiratory system with the middle ear.
