What is Human Anatomy?
Human anatomy can be precisely defined as a complementary basic medical science, which deals with the scientific study of morphology of human body. In simpler words, human anatomy is the study of structure of human body.
Subdivisions of Human Anatomy:
There are two main levels of structure of human body (as well as every other thing):macroscopic level and microscopic level. For each of the two levels. there is a separate subdivision of anatomy. The one dealing with macroscopic level is known asgross anatomy and the other which deals with microscopic level is called microscopic anatomy or histology.
Gross anatomy:
In gross anatomy, structure of human body is studied as seen by naked eye. There are two approaches for gross anatomy: Regional approach and Systemic approach.
Histology or microscopic anatomy is the study of the structure of various organs and tissues of human body under a microscope. The understanding of the ultra-structure helps understand the tissues and organs in a better way.
Introduction to Human Skeletal System:
Skeletal system is the system of bones, associated cartilages and joints of human body. Together these structures form the human skeleton.
Components of Human Skeleton:
Human skeleton is composed of three main components; Bones, Associated cartilages and Joints.
Bones:
Bone is a tough and rigid form of connective tissue. It is the weight bearing organ of human body and it is responsible for almost all strength of human skeleton. For more details visit: Basic anatomy article; “Bone“.
Cartilages:Cartilage is also a form of connective tissue but is not as tough and rigid as bone. The main difference in the cartilage and bone is the mineralization factor. Bones are highly mineralized with calcium salts while cartilages are not. For more details visit: Basic anatomy article; “Cartilage and its types“.
Joints:
Joints are important components of human skeleton because they make the human skeleton mobile. A joint occurs between “two or more bones”, “bone and cartilage” and “cartilage and cartilage”. For more details visit: “Joints”
