The soleus muscle is one of the calf muscles (triceps surae) in the superficial posterior compartment of the leg which sits deep to gastrocnemius.It is much bigger than gastrocnemius and is the primary plantar flexor. Insertion: Via calcaneal tendon to posterior surface of calcaneus *All 3 insert into the calcaneus, do plantar flexion and are innervated by the tibial nerve. Soleus Origin And Insertion. The origin of the Soleus is the upper shaft of the Fibula and the medial border of the Tibia. The soleus muscle joins the plantaris and gastrocnemius muscles to insert onto the calcaneus via a common tendon – the Achilles tendon (calcaneal tendon). Soleus: The soleus is an efficacious muscle in the posterior part of the lower leg muscles(the calf). Origin: Tibia & Fibula; Insertion: On the calcaneus via the Achilles tendon; Innervation: The muscle is innervated by the nervus tibialis. Origin. The soleus originates from the head of the fibula and the soleal line of the tibia.. Insertion. The origin. Insertion of Soleus Origin Of The Rectus Femoris is On The Ilium. The gastrocnemius muscles but not the soleus cross the knee joint, and they all distally cross the tibiotalar joint (and the subtalar joint as well). The bulk of the gastrocnemius muscle from each of the heads come together and insert into the posterior surface of a broad membranous tendon. Soleus has three origin points, one of which being the tendinous arch of soleus which spans between the tibia and fibula. Soleus. Summary. The calcaneal tendon, also known as the tendon of Achilles, is a posterior leg tendon — a fibrous connective tissue that joins muscles in the back of the leg. Where do the soleus muscles attach? Soleus muscle Origin of Soleus Posterior aspect of fibular head, upper 1/4 - 1/3 of posterior surface of fibula, middle 1/3 of medial border of tibial shaft, and from posterior surface of a tendinous arch spanning the two sites of bone origin. It then fuses with the soleus tendon to form the upper part of tendocalcaneus. It moves from its two heads just over the knee to the heel, a two joint muscle. It is the only muscle of the group which crosses the hip joint and is a powerful knee extensor when the hip is extended but is weak when the hip is flexed. Keep in mind that origin and insertion are relative terms, and can be reversed depending on the action involved. Soleus Insertion. They are located deep to the gastrocnemius. As the gastrocnemius crosses knee and ankle, the position of the knee during the plantar flexion resistance exercise affects activity of the muscle. This is a view of the back of the right leg; most of the gastrocnemius muscle has been removed. In humans and some other mammals, the soleus is a powerful muscle in the back part of the lower leg (the calf).It runs from just below the knee to the heel, and is involved in standing and walking.It is closely connected to the gastrocnemius muscle and some anatomists consider them to be a single muscle, the triceps surae.Its name is derived from the Latin word "solea", meaning "sandal". Flexor Hallucis Longus Origin: Fibula, posterior aspect of middle 1/3 Insertion: Top of the patella and the patella tendon to the tibial tuberosity. Origin: Anterior Inferior Iliac Spine (AIIS). Muscle Name Origin Insertion Action Innervation Muscles of Upper Extremity Pectoralis Major Medial half of clavicle, front of sternum, costal cartilage Crest of greater tubercle (Lateral ... Soleus -Posterior, superficial Head and posterior surface of fibula and soleal line of tibia Origin, insertion, functions, and exercises of the Soleus muscle. The soleus muscle is part of the posterior compartment of the leg. It arises from just below the knee to the heel, and is involved in standing and walking. The medial and lateral gastrocnemius tendons together with the soleus muscle form the calf. It origination on the ilium. The soleus muscle of horses is rather diminutive with respect to the overall size of adjacent synergist muscles in the hind limb of the horse. Other important calf muscle lies underneath the gastrocnemius muscle, which is named the soleus muscle. Separate the soleus from the gastrocnemius by looking inside for a division of the two muscles. The soleus muscle courses down the back of your lower leg and is located just beneath your larger gastrocnemius muscle. Given that muscles make movement happen, each muscle will create a certain movement around a joint. The gastrocnemius muscle is used more during dynamic, higher force activities and soleus muscle is more active during postural and static contractions. The insertion of the Soleus is into the Calcaneus via the Achilles Tendon. Action: The soleus extends the ankle and allows for plantar flexion. Insertion Upper third of … Soleus Action. the middle of the thigh, covering most of the other three quadriceps muscles. Plantaris Origin: Lateral supracondylar ridge of femur above lateral head of gastrocnemius Insertion: Endo calcaneus (medial side, deep to gastrocnemius tendon) Other actions: Flexes knee. Soleus is used constantly in standing to maintain an upright position. Origin: The deep digital flexor muscle has three heads, originating from the lateral condyle of the fibula, the caudal and medial aspect of the tibia. Lower Limb Muscles #2 Posterior Compartment of Leg (superficial) *Gastrocnemius and soleus both insert to the calcaneal (Achilles) tendon and together they form the “triceps surae”. Together the Gastrocnemius, Soleus, and Plantaris are known as Triceps Surae. The gastrocnemius muscles extend half-way down the lower leg, distally contributing to the Achilles tendon. They are like biceps and braciallis. Soleus is a large flat muscle located underneath gastrocnemius that received its name for its resemblance to a Sole, a type of flatfish. ORIGIN Soleal line and middle third of posterior border of tibia and upper quarter of posterior shaft of fibula including neck: INSERTION Tendo calcaneus to middle of three facets on posterior surface of calcaneus: ACTION Plantar flexes foot (aids venous return) NERVE Insertion : Semilunar crest and adjacent surface of the cartilage of the distal phalanx , continues as the deep digital flexor tendon to insert on the distal phalanx The quadriceps Muscle Origin : Rectus femoris : This Muscle Located At Centre Of The Thigh And Covers All Other Three Muscles. Whether or not such a muscle might be vestigial or may be providing some essential function has not been determined. Origin posterior border of iliac crest Insertion inferior border of 12th rib and iliolumbar ligament and ((transverse process of L1-L4)) Action: Actions Alone(unilateral), lateral flexion of vertebral column; Together (bilateral), depression of thoracic rib cage Gastrocnemius: Origin, Insertion, Action & Nerve Supply Gastrocnemius: The gastrocnemius is a very potent superficial bipennate muscle that is in the back part of the lower leg muscles. The soleus muscle and surrounding structures, from Gray's Anatomy. Origin: Originates from the fibula. Soleus Origin: Fibula, medial border of tibia (soleal line) Insertion: Tendo calcaneus. Soleus is a large muscle, deep to Gastrocnemius. For instance the quadriceps muscle group will extend the knee and flex the hip. Specifically, soleus originates on the soleal line of the tibia and on the head of the fibula. Origin: Upper half of the posterior surface of the tibia, along the soleal line. The plantaris muscle arises from the posterosuperior aspect of the lateral femoral condyle, close to the origin of lateral head of gastrocnemius. The soleus joins with the aponeuroses of the gastrocnemius, forming the calcaneal tendon or Achilles tendon that inserts onto the calcaneal tuberosity.. Action. Start studying Origin, Insertion, Action, Innervation, and Muscles of Leg. An easy way to determine the origin of any muscle is to find the point at which the muscle moves the least. [1] Another variant, the cyamella, is a small sesamoid bone embedded in the tendon of the popliteus muscle. Soleus Origin. Gastrocnemius muscle or as it is commonly referred to – “stomach of the leg” is a very important muscle of the body. origin: fibula and medial border of the tibia (soleal line) via the inverted 'U' tendinous arch; insertion: tendo calcaneus (Achilles tendon) into mid-posterior calcaneus The soleus muscle, located deep/anterior to the medial and lateral gastrocnemius muscle heads, originates on the posterior aspect of the tibia (middle third of the medial border) and fibula (head and body) and inserts on the calcaneus through the Achilles tendon (see Figure 31.1). It is located in the lower leg’s back portion and is one of the two major muscles of the calf of the leg. Soleus: Origin, Insertion, Action & Nerve Supply. It is named from its straight course. There is often an attachment to the oblique popliteal ligament. key relationships : between the medial head of the gastrocnemius and soleus; Gross anatomy Origin and insertion. Once detached from the gastrocnemius, you can use the blunt probe to lift up and see the soleus. Origin. The tables on the following pages detail the origin, insertion and action of some of the major muscles in the body. SOLEUS. The two muscles join together at the Achilles tendon and insert on the back side of your heel bone, called the calcaneus. Learn vocabulary, terms, and more with flashcards, games, and other study tools. The soleus extends down from both bones of the lower leg (tibia & fibula) its entire length, merges into the Achilles tendon and attaches onto the posterior surface of the heel. The origin of a muscle is the point at which it originates on the skeleton. Origin is inner side of the head of the fibula, insertion into the upper end of the oblique line of the tibia, it lies beneath the popliteus.
