Types of bones. Bones are classified by their shape. They may be long (like the femur and forearm), short (like the wrist and ankle), flat (like the skull), or irregular (like the spine). Primarily, they are referred to as long or short. There are 206 bones in the adult human skeleton.
Bone is hard and many of its functions depend on that characteristic hardness. Later discussions in this chapter will show that bone is also dynamic in that its shape adjusts to accommodate stresses. This section will examine the gross anatomy of bone first and then move on to its histology.
Bone is a metabolically active connective tissue that provides structural support, facilitates movement, and protects vital organs. Bone is composed of an extracellular matrix and bone cells (osteocytes). Under the right conditions, bone tissue undergoes a process of mineralisation, and is hardened by deposited calcium.
May 17, 2024 · Bone - Structure, Function, Types: Grossly, bone tissue is organized into a variety of shapes and configurations adapted to the function of each bone: broad, flat plates, such as the scapula, serve as anchors for large muscle masses, while hollow, thick-walled tubes, such as the femur, the radius, and the ulna, support weight or ...
Bone has many important jobs in the body: The skeleton is made of bone to provide a strong framework to support and protect the soft organs (such as the brain, heart, and lungs) from injury. Bone works with muscle to hold up the body when we stand and to move the body when we walk or run.
Jun 14, 2024 · Human skeleton, the internal skeleton that serves as a framework for the body. This framework consists of many individual bones and cartilages. There also are bands of fibrous connective tissue—the ligaments and the tendons—in intimate relationship with the parts of the skeleton.

Jul 1, 2023 · Lamellar bone (secondary bone) – The bone of the adult skeleton. It consists of highly organised sheets of mineralised osteoid. This organised structure makes it much stronger than woven bone.
Calcium is required for bone, muscle and nerve health. The main store for calcium in your body are the bones, where it contributes to bone structure and strength.
Short Bones. A short bone is one that is cube-like in shape, being approximately equal in length, width, and thickness. The only short bones in the human skeleton are in the carpals of the wrists and the tarsals of the ankles. Short bones provide stability and support as well as some limited motion.
Bones are living tissues. Your body constantly breaks down old bones and grows new tissues to replace them. Although bone replacement slows down in your 20s, many people achieve their peak bone mass in their 30s. If you have a higher peak bone mass, your bones are stronger.
One of the most common indications of a bone scan is to determine the status of the bones in cases of cancer. Bone scanning is also useful in detecting abnormalities in the skeletal system, such as bone infection, fractures due to strenous exercises, Paget's disease, benign bone tumour e.g. osteo osteoma, tumours and even in cases of child abuse.
