Ankle Joint The ankle joint is a complex system of a combination of bones, ligaments and muscles that hold together the foot in place. Built to serve several purposes like bearing weight, mobility, adaptability and stability, the ankle and the foot together serve as a connection to the ground. The ankle must withstand body weight as well as to adapt to the changing surfaces on which we walk. The ankle is made up of two joints − the true ankle joint and the subtalar joint. The true ankle joint is a specially designed joint that holds together the leg ... Read More

Three Main Bones of the Leg Starting from the hip to the ankle, three bones which form the leg are as − Femur Tibia Fibula. Femur − Femur is the single, thick bone that runs from the hip joint to the knee joint. It’s the strongest bone of the leg accounting for one-quarter of the total height of a person. Tibia − Tibia runs along the lower leg, and is called the shin bone. Along with the fibula, it runs from the knee joint to the ankle. It is stronger and thicker than fibula. Fibula − Fibula along ...

The Foot The foot is one of the intricate structures comprising 26 bones linked at 33 joints. The foot bones provide mechanical support both while walking and standing by supporting the body weight. The foot bones are grouped under the following three categories − Tarsals Metatarsals Phalanges. Tarsals A set of seven irregular bones form the tarsals situated at the proximal end of the ankle joint. Let us see each set in detail spreading out from the ankle joint. The talus or ankle bone − the two lower leg bones, tibia and fibula, connect with the talus ... Read More

Blood Circulatory System The human circulatory system, also known as the blood vascular system, is made up of a muscle-chambered heart, a network of closed branching blood arteries, and blood, which is the fluid that circulates.Alternatively, the circulatory system is in charge of collecting metabolic waste and toxins from cells and tissues so that they can be cleansed or evacuated from the body. Images Coming soon Organs of the Circulatory System Our heart is the only circulatory system organ. Heart The mesodermally derived organ, the heart, is located in the thoracic cavity, between the two lungs, and is slightly inclined ... Read More

What is Blood? Plasma, blood cells, and platelets make up blood, which is a fluid connective tissue. It transports oxygen and nutrients to many cells and tissues throughout our bodies. It accounts for about 8% of our body weight. A typical adult has about 5-6 litres of blood. Images Coming soon What is Plasma? Plasma is a sticky, straw-colored fluid that makes up roughly 55% of the blood. Water makes about 90-92% of the plasma, with proteins accounting for 6-8%. The primary proteins are as follows − Fibrinogen Globulins Albumins. Fibrinogens are required for blood clotting and coagulation. ... Read More

Introduction Anatomy of the human body describes the structure and relationship between all organs. On the other hand, the physiology of the human body describes the functions of all organs. All the organ systems of the body work together to perform a particular task or a group of tasks. Anatomy and physiology are closely related and constitute various organ systems like the respiratory system, digestive system, nervous system, cardiovascular system, urinary system, and reproductive systems. The functions of these systems help in body growth and development as well as make the body healthy and fertile. What do you understand by ... Read More
