Bone is a composite material, like fiberglass (something hard [and thus brittle] in a matrix of a more flexible substance.
In fiberglass the glass makes the (fishing rod) strong, the plastic makes it tough.
In bone, the calcium salts make it strong and hard, the connective tissue makes it tough.

What is the purpose of a long bone?
The purpose of a long bone is to support the body and provide structure, as well as assist in movement and mobility. Long bones also play a role in producing red and white blood cells in the bone marrow.
What happens to a chicken bone soaked in cola?
When a chicken bone is soaked in cola, the acidic nature of the cola can weaken the bone structure. Over time, the cola can dissolve some of the calcium and minerals in the bone, causing it to become softer and potentially break down.
What is the main function of Diaphysis?
The main function of the diaphysis is to provide structural support and protection to the long bone. It also serves as a site for muscle attachment and helps in the transmission of forces during movement.
What is an example of a long bone?
Examples of long bones are the femur, tibia, and fibula of the leg, the humerus
Thin layer of connective tissue lined with the medullary cavity of a long bone?
Endosteum is a thin layer of connective tissue that lines the medullary cavity of a long bone. It contains osteoprogenitor cells that differentiate into osteoblasts to aid in bone growth and repair. Its function is to support bone growth and remodeling by providing a surface for bone-forming cells.
What are the three hormones for long bone growth?
calcium, phospherous
What is the purpose of a long bone?
The purpose of a long bone is to support the body and provide structure, as well as assist in movement and mobility. Long bones also play a role in producing red and white blood cells in the bone marrow.
How can the structure and function of bone be described?
brode
What is the function of nutrient foramina in a long bone?
They provide passageways for blood vessels to enter the bone.
What is the function of a vein in a long bone?
Veins in a long bone function primarily to transport deoxygenated blood away from the bone and return it to the heart. They are part of the bone's vascular system, helping to maintain proper blood circulation and nutrient exchange. Additionally, veins assist in regulating the bone's temperature and contribute to the overall metabolic processes within the bone tissue.
What is plastacine?
Plasticine is a modeling clay originally developed and patented in 1899. It iscomposed of calcium salts (e.g. calcium carbonate), petroleum jelly, and long-chain aliphatic acids (e.g. stearic acid).
What mineral is stored in the skeletal system?
The skeletal system is a major repository of calcium.
What happens to a chicken bone soaked in cola?
When a chicken bone is soaked in cola, the acidic nature of the cola can weaken the bone structure. Over time, the cola can dissolve some of the calcium and minerals in the bone, causing it to become softer and potentially break down.
How strong is an egg shell?
Calcium The calcium for the eggshell comes from three sources - the diet, special bone called medullary bone (found in the cavity of all birds long bones) of pullets and the hens skeleton. The hen uses approximately 2.5 grams of calcium in the formation of one normal egg. When diet alone cannot supply this amount the calcium will be sourced internally.
What part of the long bone is for strength?
The diaphysis, or shaft, of a long bone is primarily designed for strength. It is composed of dense, compact bone that provides structural support and resistance to bending and torsion. This central region houses the medullary cavity, which contains bone marrow, contributing to the overall strength and function of the bone.
What is the structural and function feature of the epiphysis?
Epiphysis are found at both ends of a long bone. They are made of cancellous bone filled with marrow. They have a bulbous shape and function to provide attachments for muscles and give stability to joints.
What is the structural and function feature of the diaphysis?
The diaphysis is the main shaft of long bone. It is hollow, cylindrical in shape and thick, and composed of compact bone. It's function is to provide strong support without cumbersome weight and provides a space (medullary cavity) that contains precursors of blood cells.
