The achilles tendon, tendo calcaneus attaches distally to the calcaneual tuberosity, and arises superiorly from the triceps surae complex of the gastrocnemius and soleus muscles. Achilles tendon at foetus. The Achilles tendon connects muscle to bone, like other tendons, and is located at the back of the lower
Osborne's ligament, also Osborne's band, Osborne's fascia, Osborne's arcade, arcuate ligament of Osborne, or the cubital tunnel retinaculum, refers to either the connective tissue which spans the humeral and ulnar heads of the flexor carpi ulnaris (FCU) or another distinct tissue located between the olecranon process of the ulna and the medial epicondyle of the humerus.
The muscle which can 'cancel' or to some degree reverse the action of the muscle. Muscle synergies are noted in parentheses when relevant. O (Occurrences) Number of times that the named muscle row occurs in a standard human body. Here it may also be denoted when a given muscles only occurs in a male or a female body.
The olecranon is situated at the proximal end of the ulna, one of the two bones in the forearm. [1] When the hand faces forward the olecranon faces towards the back (posteriorly). It is bent forward at the summit so as to present a prominent lip which is received into the olecranon fossa of the humerus during extension of the forearm. [2] [3]
Anatomical diagrams illustrating the components of the plantar fascia. Dissection of the plantar aponeurosis: LP, lateral part; CP, central part; MP, medial part; L, length; W, width. Five central part plantar aponeurosis bundles. The plantar fascia is the thick central portion of the fascia investing the plantar muscles.
The muscle originates from the forepart of the upper and lateral surface of the calcaneus (in front of the groove for the peroneus brevis tendon), from the interosseous talocalcaneal ligament and the stem of the inferior extensor retinaculum. The fibres pass obliquely forwards and medially across the dorsum of the foot and end in four tendons.
The leg muscles acting on the foot are called the extrinsic foot muscles whilst the foot muscles located in the foot are called intrinsic. [28] Dorsiflexion (extension) and plantar flexion occur around the transverse axis running through the ankle joint from the tip of the medial malleolus to the tip of the lateral malleolus.
The fibularis longus also tilts the sole of the foot away from the midline of the body . Because of the angle at which it crosses the sole of the foot, it plays an important role in maintaining the transverse arch of the foot. [2] Together, the fibularis muscles help to steady the leg upon the foot, especially in standing on one leg. [2]
