Malleolus For other uses, see Malleus (disambiguation). A malleolus is the bony prominence on each side of the human ankle. Each leg is supported by two bones, the tibia on the inner side (medial) of the leg and the fibula on the outer side (lateral) of the leg. The medial malleolus is the prominence on the inner side of the ankle, formed by the lower end of the tibia.

What is the Lateral Malleolus? The lateral malleolus is a bony prominence on the fibula, one of the long bones that makes up the lower leg. The fibula is the narrowest of the long bones, situated on the outside of the leg, with this prominence creating the distinctive bump on the outside of the ankle.

Bird feet and legs The fibula is also reduced. The legs are attached to a very strong assembly consisting of the pelvic girdle extensively fused with the uniform spinal bone (also specific to birds) called the synsacrum, built from some of the fused bones. Bird leg and feet anatomy is very diverse. It reveals many accommodations to perform a wide variety of functions.

Muscles that Move the Ankle and Foot They dorsiflex the ankle and extend the toes. Fibularis (peroneus) tertius: This muscle originates on the anterior surface of the shaft of the fibula and inserts on the base of the fifth metatarsal bone.It dorsiflexes the ankle and everts the foot.ome of the muscles that move the foot start higher up in the leg, and smaller muscles work right in the foot itself. The leg is divided into compartments: the anterior, lateral, and posterior compartments. The muscles in these compartments help move the ankle and the foot:

Anatomy of the Calcaneus Anatomy of the Calcaneus. The Calcaneus or heel bone is one of the seven tarsal bones of the foot. Tarsal bones are present between the bones of the leg (tibia and fibula) and the five metatarsal bones, and are collectively referred to as tarsus of the foot. The Calcaneus is the largest of all the bones in the foot. It is roughly cuboidal in shape and has six distinct surfaces.

Foot Anatomy The hindfoot is composed of three joints and links the midfoot to the ankle (talus). The top of the talus is connected to the two long bones of the lower leg (tibia and fibula), forming a hinge that allows the foot to move up and down. The heel bone (calcaneus) is the largest bone in the foot. It joins the talus to form the subtalar joint. The bottom of the heel bone is cushioned by a layer of fat.

- Thus has it been said that The Malleus Maleficarum is one of the most blood-soaked works in human history, in that its very existence reinforced and validated Catholic beliefs which led to the prosecution, torture, and murder, of tens of thousands of innocent people.t the height of its popularity, The Malleus Maleficarum was surpassed in public notoriety only by The Bible. Its effects were even felt in the New World, where the last gasp of the Inquisition was felt in the English settlements in America (most notably in Salem, Massachusetts during the Salem Witch Trials).

UNIT VIII â The Foot and Ankle The talus and the calcaneus are the two most posterior bones in the foot, as well, as the largest of the tarsal bones of the foot. The talus articulates with the distal tibia and fibula above to form the mortise joint of the ankle.It articulates below with the calcaneus. No muscles actually insert on the talus.he foot and ankle are generally discussed by breaking them into several anatomical regions. The ankle joint, which is the distal aspect of the tibia and the fibula articulating with the talus, is the most proximal joint.

How do you treat a broken ankle? How long does it take to heal? Treatment: Posterior Malleolus Fracture. A posterior malleolus fracture is a fracture of the back of the tibia at the level of the ankle joint. In most cases of posterior malleolus fracture, the lateral malleolus (fibula) is also broken. This is because it shares ligament attachments with the posterior malleolus. There can also be a fracture of the medial malleolus. Depending on how large the broken piece is, the back of the ankle may be unstable.

Flexor retinaculum of foot The flexor retinaculum of foot ( laciniate ligament , internal annular ligament ) is a strong fibrous band , extending from the bony ankle prominence ( malleolus ) above , to the margin of the heelbone ( calcaneus ) below , converting a series of bony grooves in this situation into canals for the passage of the tendons of the flexor muscles and the ...

Foot Callus Treatment And Prevention What Are Foot Calluses? Foot calluses are thick patches of skin that can be dark in color or dusty and cracked in texture. Many people have calluses on their feet. Calluses most commonly form on the knuckles of the toes or on the heels and balls of the feet. The affected areas can feel rough and take on a dry appearance. Calluses are basically dead skin that has hardened over softer portions of the skin.

Numbness in the Heel? The tarsal tunnel is a canal linking part of the ankle bone, called the medial malleolus, to a set of ligaments, called the flexor retinaculum, which span the foot. The tendons, nerves and arteries that enable your foot to be flexible and mobile are located inside of this canal.

- What is a callus? Corns and calluses are hard, thickened areas of skin that form as a consequence of rubbing, friction, or pressure on the skin. Corns and calluses form on the feet and can make walking painful. Although corns and calluses are often talked about together, they are separate conditions. Corns generally occur on the tops and sides of the toes. A hard corn is a small patch of thickened, dead skin with a small plug of skin in the centre.

Malleus The malleus is the outermost and largest of the three small bones in the middle ear, and reaches an average length of about eight millimeters in the typical adult. It is informally referred to as a hammer, owing to it being a hammer-shaped ossicle or small bone that is connected to the ear.

Peroneus longus In human anatomy, the peroneus longus (also known as fibularis longus) is a superficial muscle in the lateral compartment of the leg, and acts to evert and plantar flex the ankle.he fibularis longus and brevis muscles plantar-flex the foot, in conjunction with the tibialis posterior, antagonizing the tibialis anterior and fibularis tertius, which are dorsi-flexors of the foot.

- The talus is the second largest tarsal bone, and it is situated above the calcaneus in the hindfoot. This bone is unique in that two thirds of the talar surface is covered with articular cartilage, and neither tendons nor muscles insert or originate from this bone.he cuboid bone is placed on the lateral side of the foot, in front of the calcaneus, and behind the fourth and fifth metatarsal bones. It is cuboidal in shape but has a broader base oriented medially (see the image below). Lateral view of the calcaneus and cuboid bones.

Foot The foot is an anatomical structure found in many vertebrates. It is the terminal portion of a limb which bears weight and allows locomotion. In many animals with feet, the foot is a separate organ at the terminal part of the leg made up of one or more segments or bones, generally including claws or nails.

Ossicles The malleus (Latin: hammer) articulates with the incus through the incudomalleolar joint and is attached to the tympanic membrane (eardrum), from which vibrational sound pressure motion is passed. The incus (Latin: anvil) is connected to both the other bones.
