Bones. The femur, or thighbone, is the longest and largest bone in the human body. At its top, it helps create the ball-and-socket joint of the hip; its lower end helps create the knee joint. The ...
It is the region between the knee and the ankle, consisting of two long bones: Lower Leg Bones. Tibia (2): It is the longer and thicker of the two bones, located medially in the lower leg. The weight-bearing bone articulates with the femur at its superior end and the tarsals at its inferior end. Fibula (2): Located laterally, it articulates ...
Plantaris. This is a small muscle in the back of the lower leg. Like the gastrocnemius and soleus, it’s involved in plantar flexion. Tibialis muscles. These muscles are found on the front and ...
The human body contains 60 lower limb bones, with 30 in each leg. Some of these bones are structured to absorb 2-3 times the body’s total weight in force. The average person takes approximately 5,000 steps per day, which requires the lower limb bones to be durable for continuous use.
Human leg. The leg is the entire lower limb of the human body, including the foot, thigh or sometimes even the hip or buttock region. The major bones of the leg are the femur (thigh bone), tibia (shin bone), and adjacent fibula. The thigh is between the hip and knee, while the calf (rear) and shin (front), or shank, are between the knee and ankle.
The main parts of the knee joint are the femur, tibia, patella, and supporting ligaments. The condyles of the femur and of the tibia come in close proximity to form the main structure of the joint. The patella, commonly known as the ‘kneecap’, is a sesamoid bone that sits within the tendon of the quadriceps femoris.
In the realm of anatomy, the ‘leg’ is strictly the region between the knee and the ankle joints rather than the entire lower extremity, as erroneously referred to in common language. In this small section, we’ll briefly mention the main parts of the leg, namely the bones, muscles, and neurovasculature.
Toggle Anatomy System. The bones of the leg and foot form part of the appendicular skeleton that supports the many muscles of the lower limbs. These muscles work together to produce movements such as standing, walking, running, and jumping. At the same time, the bones and joints of the leg and foot must be strong enough to support the body's ...
The leg is the region of the lower limb between the knee and the foot. It comprises two bones: the tibia and the fibula. The role of these two bones is to provide stability and support to the rest of the body, and through articulations with the femur and foot/ankle and the muscles attached to these bones, provide mobility and the ability to ambulate in an upright position. The tibia ...

Accessed 29 October 2024. Leg, limb or appendage of an animal, used to support the body, provide locomotion, and, in modified form, assist in capturing and eating prey (as in spiders and insects). In four-limbed vertebrates all four appendages are commonly called legs, but in bipedal animals only the lower two are so called.
Leg Bone Anatomy Femur. The femur is also known as the thigh bone. It is the longest and strongest bone in the human body. It gives us the ability to stand and move with strength and stability. This bone is subdivided into three different parts: the upper portion (proximal), the central body (shaft), and the lower section (distal).
Lower leg. The lower leg is a major anatomical part of the skeletal system. Together with the upper leg, it forms the lower extremity. It lies between the knee and the ankle, while the upper leg ...
The Skeletal System. Explore the skeletal system with our interactive 3D anatomy models. Learn about the bones, joints, and skeletal anatomy of the human body. The skeletal system includes all of the bones and joints in the body. Each bone is a complex living organ that is made up of many cells, protein fibers, and minerals.
Vascular Supply. Lower Limb Veins. Lower Limb Arteries. 3D interactive models and tutorials on the anatomy of the lower limb, including the muscular compartments, osseus structures, blood supply and innervation.
The lower leg refers to the portion of the lower extremity between the knee and ankle. This area consists of bones, muscles, tendons, and nerves that all work together to allow the leg to function ...
Long bones: Long bones are exactly what they sound like — the longest bones in your body, especially in your arms and legs. Examples of long bones include the femur (your thigh bone) and the humerus (your upper arm bone). The two bones in your lower leg — the tibia (your shin bone) and fibula (your calf bone) — are also long bones.
The thigh bone, or femur, is the large upper leg bone that connects the lower leg bones (knee joint) to the pelvic bone (hip joint). Review Date 4/24/2023 Updated by: C. Benjamin Ma, MD, Professor, Chief, Sports Medicine and Shoulder Service, UCSF Department of Orthopaedic Surgery, San Francisco, CA.
Anatomy of the Femur. The femur is a type of long bone. Longer than it is wide, this type of bone has spongy bone tissue at both ends and a cavity filled with bone marrow in the shaft. Other types of bones include short bones, flat bones, and irregular bones. The only bone in the upper leg, the femur is divided into three parts: proximal, shaft ...
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. This article is concerned primarily with the gross ...
