1. Bone type

"Bone" refers to the hard tissue that constitutes bones in human body or animal body. In biology, bones can be divided into long bones, short bones, flat bones and irregular bones according to their shapes and functions. Different kinds of bones are different in structure and function.

2. Bone structure

Bones are composed of organic and inorganic substances. Organic substances are mainly collagen, which endows bones with elasticity and tensile properties. Inorganic substances are mainly minerals such as calcium phosphate and calcium carbonate, which make bones hard and have load-bearing capacity. Bone also includes trabecular bone, bone marrow cavity and other structures, which are used to supply blood and store bone marrow.

3. Physiological function of bone

As the main component of human skeleton, skeleton has important physiological functions. First of all, bones provide support and protection, keep the human body in a normal posture and shape, and protect internal organs from external injuries. Secondly, bones participate in blood production and mineral metabolism, produce red blood cells, white blood cells and platelets through bone marrow cavity, and store important minerals such as calcium and phosphorus.

4. Clinical significance of bone

Bone has important clinical significance in the medical field. Orthopedics is a branch of medicine that specializes in the study and treatment of bone-related diseases. Bone system diseases such as fracture, osteoporosis and arthritis are common in clinic and need to be intervened by surgery, medicine or physical therapy. In addition, bone marrow transplantation and bone tissue engineering also provide new methods for clinical treatment.

Summary:

The English pronunciation of bone is "bone", which refers to the hard tissue that constitutes bones in human or animals. The types of bones vary according to their shapes and functions, and their structures are composed of organic and inorganic substances. Bone has important physiological functions in human body, such as support, protection, hematopoiesis and mineral metabolism. In the medical field, the clinical significance of bone is very important, involving the treatment of orthopedic diseases and the application of related technologies.

Bone organic matter is mainly collagen, which gives bones elasticity and tensile properties. Inorganic substances are mainly minerals such as calcium phosphate and calcium carbonate, which make bones hard and have load-bearing capacity. Bone also includes trabecular bone, bone marrow cavity and other structures, which are used to supply blood and store bone marrow.
