Anatomy of leg and foot. At the same time the bones and joints of the leg and foot must be strong enough to support the bodys weight while remaining flexible enough for movement and balance. The foot consists of thirty three bones twenty six joints and over a hundred muscles ligaments and tendons. The gastrocnemius muscle has two large bellies called the medial head and the lateral head.

Its main function is to allow for plantar flexion and dorsiflexion of the foot. The muscles of the lower leg called simply the leg by anatomists largely move the foot and toes. The anterior muscles such as the quadriceps femoris iliopsoas and sartorius work as a group to flex the thigh at the hip and extend the leg at the knee.

Foot and ankle anatomy is quite complex. This may sound like overkill for a flat structure that supports your weight but you may not realize how much work your foot does. These all work together to bear weight allow movement and provide a stable base for us to stand and move on.

The foot contains 26 bones 33 joints and over 100 tendons muscles and ligaments. Foot and ankle anatomy. The ankle is a joint that connects the lower leg to the foot.

The femur or thigh bone is the largest heaviest and strongest bone in the human body. Posterior muscles such as the hamstrings and gluteus maximus produce the opposite motion extension of the thigh at the hip and flexion of the leg at the knee. As these nerves descend toward the thighs they form two networks of crossed nerves known as the lumbar plexus and sacral plexus.

The major muscles of the lower leg other than the gastrocnemius which is cut away are shown in figure 9 12. The foot is responsible for balancing the bodys weight on two legs a feat which modern roboticists are still trying to replicate.
