What You Need to Know About the Muscles of the Leg

If you’re interested in learning about the muscles in your leg, you’ve come to the right place. Here, you’ll learn about their functions, where they are located, and their branched structure. You’ll also learn about their location and tendons. Once you understand these muscles and their functions, you’ll be able to use them effectively. Regardless of the sport you enjoy, you can learn more about them by reading this article.


There are several tendon structures in the leg. The tibialis anterior tendon originates on the lateral surface of the tibia and attaches to the medial cuneiform and the base of metatarsal I. The extensor digitorum longus tendon is attached lateral to the tibialis anterior and travels to the dorsal surface of the foot. Upon reaching the foot, the tendons attach to the lateral four toes.


The legs contain a number of muscles that control various movements in the body, including walking, running, and jumping. The muscles are divided into anterior and posterior groups, and there are different subgroups. These muscles are categorized according to the type of innervation they receive. The muscles of the anterior compartment supply sensory and motor innervation to the foot and ankle. The posterior compartment contains the calf muscles and gastrocnemius.


The leg’s muscles are arranged in a quadriceps group, which attaches to the upper leg. The word quadriceps comes from the Greek and means “four-headed muscle,” so the term refers to a group of four individual muscles. The four muscles of the quadriceps group control ankle and foot motion. Each muscle belongs to a distinct group, with a specific function and location.


The thigh and leg muscles are grouped together into three main groups: hip flexors (psoas, sartorius, and pectineus), and adductor magnus and femoris. These muscles are divided into three separate plexuses, each supplying part of the leg. The tibial nerve is located on the medial side of the thigh and lies lateral to the popliteal artery. The perforating branches supply the medial, lateral, and posterior portions of the thigh muscles.


If you are experiencing pain due to a traumatic injury, you should seek medical attention immediately. In the first 24 to 72 hours after the injury, you should avoid heavy activity to prevent further bleeding, exacerbating fibrillar necrosis, and allowing the wound to heal properly. Complete hematomas of the lower leg often require total abstinence from load for 48 hours, but the duration of rest depends on the severity of the traumatic injury and the patient’s pain. Sometimes, elevated limbs are helpful in healing a hematoma, lowering blood pressure and increasing venous return.
