Muscles of the Lower Leg

By Edited Jun 14, 2014 0 0

Muscles of the Lower Leg Anatomy
The muscles of lower legs are comprised of very powerful structures that allow human beings to walk, run, and jump.  The entire human body is relatively heavy. Without strong muscles, an individual will not be able to carry his or her body. The lower leg muscles are designed to carry heavy weights. When these muscles are developed and improved greatly, such as with athletes, the human body can perform great activities.

Overview of the Muscles of Lower Legs

Anatomy of the Muscles of the Lower Leg
There are several muscles that involve the lower legs. These muscles are divided into several parts and compartments for easy identification. The compartments have anterior and posterior sides. The lower leg muscles are voluntary muscles that are connected by tendons. These are long muscles that are bundled together to make it stronger and able to perform the function of walking, running, jumping, and carrying the weight of the human body. These muscles work closely together with the skeletal system that is why they are called the skeletal muscles.

Different Muscles of Lower Legs

  • Fibularis longus - Muscles of the Lower Leg Anatomy

  • Fibularis brevis - Muscles of the Lower Leg Anatomy
    Fibularis brevis
  • Extensor digitorum longus - Muscles of the Lower Leg Anatomy
    Extensor digitorum longus
  • Fibularis tertius - Muscles of the Lower Leg Anatomy

  • Soleus - Muscles of the Lower Leg Anatomy

  • Gastrocnemius - Muscles of the Lower Leg Anatomy

The muscles of lower legs are connected to the bones through tendons. The anterior compartment is composed of the fibularis longus, fibularis brevis, anterior tibialis, extensor digitorum longus, fibularis tertius, and the soleus. The posterior compartment is composed of the gastrocnemius, and a part of the soleus.

Anatomy of the Lower Leg Muscles

Anatomy of Lower Leg Muscles
The anterior tibialis is a superficial muscle located on the anterior part of the lower leg. It functions to dorsiflex and invert the foot.  The extensor digitorum longus is located laterally to the anterior tibialis. It is a prime mover of toe by extending and dorsiflexing it. The fibularis muscles are composed of the longus, brevis, and tertius. These muscles are located on the lateral part of the leg and flexes or everts the plantar surface of the foot. This group of muscles arises from the fibula and insert into the metatarsal bones of the foot. Gastrocnemius forms the curved calf of the posterior leg and is connected to the heel of the foot through the Achilles tendon. It is the primary mover for plantar flexion of the foot. The soleus is located deep into the gastrocnemius. It arises from the tibia and does not affect knee movement but it is a strong plantar flexor of the foot. The muscles of lower legs are connected to different tendons. If the tendons are damaged, walking will be greatly affected.

Summary of the Anatomy of the Lower Leg Muscle

The muscles of lower legs play a vital role for the locomotion of the human body. They are divided into different compartments and have specific functions. Without these muscles, walking would not be possible.

It is very important to take care of the lower leg muscles to reduce injuries. Sports enthusiasts, athletes, and even ordinary people often use these muscles. With all these being said, It is only logical for us to take care of these marvelous muscles of lower legs.
