The soleal line is a prominent ridge on the posterior surface of the tibia. It extends obliquely downward from the back part of the articular facet for the fibula to the medial border, at the junction of its upper and middle thirds. Development The soleal line becomes more prominent between childhood and adulthood. [1] The soleal (popliteal) line is the rough ridge found on the proximal half of the posterior surface of tibia. It extends inferomedially from the fibular articular facet to the medial border of tibia. It provides an origin site for the soleus muscle, and an attachment site for the transverse intermuscular septum of leg. Complete Anatomy
Tibia and Fibula Bones Posterior View
The tibia (shin bone) is a long bone of the leg, found medial to the fibula. It is also the weight bearing bone of the leg, which is why it is the second largest bone in the body after the femur. Fun fact here is that 'tibia' is the Latin word for tubular musical instruments like the flute. The tibia is one of two bones that comprise the leg. [1] As the weight-bearing bone, it is significantly larger and stronger than its counterpart, the fibula. The tibia forms the knee joint proximally with the femur and forms the ankle joint distally with the fibula and talus. Definition The soleal line is a diagonal bony ridge that is located in the upper portion of the posterior surface of tibia. It is oriented downward and medially. Above the soleal line, the triangular region of the posterior surface of tibia serves as the point of origin for the popliteus muscle. The soleus muscle arises from the soleal line on the dorsal surface of the tibia, medial border of the tibia, head of the fibula, and posterior border of the fibula. Part of the fibers arises from the tendinous arch of the soleus, which spans between the tibia and fibula and arches over the popliteal vessels and tibial nerve.
Tibia (Shin Bone) Definition, Location, Anatomy, & Diagrams
This line is the site of origin for part of the soleus muscle, and extends inferomedially, eventually blending with the medial border of the tibia. There is usually a nutrient artery proximal to the soleal line. Lateral border - also known as the interosseous border. Last modified: 13 December 2020 The structure indicated is the soleal line of the tibia. The soleal line is an oblique line visible on the posterior surface of the tibia. The popliteus muscle inserts above the soleal line. Three other muscles in the posterior compartment of the leg take their origin, or part of their origin from the soleal line: - soleal line of tibia; - middle one third of the medial border of tibia. The soleus muscle also originates from a fibrous band that extends from its origin sites on the fibula and tibia, known as the tendinous arch of soleus. Insertion. The soleus is a muscle within the superficial compartment of the posterior leg. It is a flat muscle located underneath the gastrocnemius, and gets its name from its resemblance to a sole - a flat fish. Attachments: Originates from the soleal line of the tibia and proximal fibula.
Tibia Anterior And Posterior View
On the posterior aspect of the tibia, the soleal line runs diagonally in a distal-to-medial direction across the proximal third of the tibia. [2] Lateral Distal End The lateral aspect of the distal tibia forms the fibular notch, creating an articulation between the distal tibia and fibula, the distal tibiofibular joint. [3] It comprises two bones: the tibia and the fibula. The role of these two bones is to provide stability and support to the rest of the body, and through articulations with the femur and foot/ankle and the muscles attached to these bones, provide mobility and the ability to ambulate in an upright position.
Origin: Fibula, medial border of tibia (soleal line) Insertion: Tendo calcaneus Artery: Sural arteries Nerve: Tibial nerve, specifically, nerve roots L5-S2 Action: Plantarflexion Antagonist: Tibialis anterior muscle Description: The Soleus is a broad flat muscle situated immediately in front of the Gastrocnemius. Itarises by tendinous fibers from the back of the head of the fibula, and from. It features a bony ridge called the soleal line. The line crosses this surface diagonally and eventually blends with the medial border of the tibia. Distal Tibia and its Bony Landmarks. At the distal end, the tibia widens and appears rectangular in cross-section. It has two bony landmarks, the medial, malleolus, and fibular notch. 1.
Tibial Anatomy
Lateral. Markedly prominent ossification obliquely across the upper tibias at the origin of the soleal muscles seen as a thick osseous protrusion on the lateral projection. This is not pathological. Note also ossification at the quadriceps insertion into the upper patella and tibial insertion of the patellar tendon. The soleus muscle originates from the head and upper third of the posterior border of the fibula, soleal line and middle third of the medial border of the tibia and tendinous arch between the fibula and tibia. Insertion. The soleus joins with the gastrocnemius, and both muscles form a common tendon called the calcaneal or Achilles tendon that.
