The nerves of the lower limb lie lateral to the artery in the upper and lower third of the leg and anterior to the artery in the middle one-third. It originates from the sacral plexus L4-S3 and travels all the way down the posterior aspect of the lower limb The sciatic nerve innervates the entire skin of the leg the posterior thigh muscles and the muscles of the leg and foot.
The gastrocnemius is the larger calf muscle forming the bulge visible beneath the skin.
Diagram of the 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 myology of the lower limb is also particularly well represented in this atlas of anatomy with multiple anatomical charts and diagrams. The first diagram summarizes the different muscular compartments fascial compartments of the thigh and leg and the different fascias crural fascia intermuscular septum interosseous membrane adductor canal fascia lata. Bone Structure of the Lower Leg.
The lower leg is made up of two very strong long bonethe tibia and the fibula. The tibia also known as the shin bone is the stronger and larger of the two. It is located toward the middle of the lower leg.
The fibula or calf bone is. Anatomy Of Lower Extremity Leg Artery Supplement Diagram. In this image you will find anatomy of lower extremity leg artery supplement diagram celiac trunk common hepatic a superior mesenteric a deep circumflex iliac a external iliac a superficial epigastric a.
You will also find superficial circumflex iliac a profunda. The medial larger bone of the lower leg. The proximal portion of the tibia is tibial plateau which acts as a cusp for the knee the distal portion tapers into the medial malleoli and the concave surface which articulates with the talus at the ankle joint.
The smaller lateral bone of the lower leg. The head of the fibula serves as an attachment point for the lateral collateral ligament of the knee and a. In the leg it accompanies the anterior tibial artery and has similar relations.
The nerves of the lower limb lie lateral to the artery in the upper and lower third of the leg and anterior to the artery in the middle one-third. The lateral terminal branch turns laterally and ends in a pseudoganglion deep to the extensor digitorum Brevis. There are four main pulse points in the lower limb.
Femoral popliteal posterior tibial and dorsalis pedis. The femoral pulse can be palpated as it enters the femoral triangle midway between the anterior superior iliac spine of the pelvis and the pubis symphysis the mid-inguinal point. The lymphatic vessels of the lower limb consist of 2 major groups superficial and deep whose distribution is mirrored closely to the major blood vessels of the lower limb.
In this article we shall discuss the general layout of lymph within the lower limb some of the major nodes involved and some relevant clinical conditions. The lower leg has two muscle groups to move the ankle foot and toes. The bones of the lower leg are the tibia and fibula.
The tibia bears most of the weight and the fibula serves as attachment. The leg is specifically the region between the knee joint and the ankle joint. Distal to the ankle is the foot.
The lower limb contains 30 bones. These are the femur patella tibia fibula tarsal bones metatarsal bones and phalanges see Figure 651. The femur is the single bone of the thigh.
It originates from the sacral plexus L4-S3 and travels all the way down the posterior aspect of the lower limb The sciatic nerve innervates the entire skin of the leg the posterior thigh muscles and the muscles of the leg and foot. The obturator nerve innervates the adductor muscles as well as the skin on the medial aspect of the thigh. 3D interactive models and tutorials on the anatomy of the lower limb including the muscular compartments osseus structures blood supply and innervation.
The calf muscle on the back of the lower leg is actually made up of two muscles. The gastrocnemius is the larger calf muscle forming the bulge visible beneath the skin. The gastrocnemius has.
Using the full-scale leg model locate and identify the muscles of the lower leg listed in the table below. Write down the muscles of the thigh in the table below and for each give the location of that muscle and what effect contracting that muscle has. Hand drawn diagrams of.

The human leg in the general word sense is the entire lower limb of the human body including the foot thigh and even the hip or gluteal region. Observe the leg muscle diagram posted above and notice that there are many parts in the muscles. Ebraheims educational animated video showing 3D animation of the nerves of the lower legThe tibial nerve is a branch of the sciatic nerve.
They support the legs to bear the body weight and also help in proper locomotion. Any disorder or defect in the knee bone can restrict the activities of the leg which can directly affect our locomotion. Below given knee diagram will help you to understand the various parts and functioning of the knee joint.
Labeled Diagram of the Knee Joint. Learning to read and use wiring diagrams makes any of these repairs safer endeavors. Well break down the anatomy and function of the upper leg knee lower leg ankle and foot.
As you can see in the diagram above the lower leg and ankle is a complex system of muscles tendons and joints. This system works to provide both stability and mobility while we walk or run. Pay special attention to the Gastrocnemius and Soleus muscles as well as the Calcaneal Achilles tendon as those will be the focus of this discussion.
