Inversion and eversion are movements that tilt the sole of the foot away from (eversion) or towards (inversion) the midline of the body. [35] Eversion is the movement of the sole of the foot away from the median plane. [36] Inversion is the movement of the sole towards the median plane. For example, inversion describes the motion when an ankle ...
Supination is the opposite, and occurs when the foot impacts the ground and there is not enough of an "inward roll" in the foot's motion. The weight of the body is not transferred at all to the big toe, forcing the outside of the foot and the smaller toes which cannot handle the stress as well to take the majority of the overweight instead.
Pronation and supination refer to rotation of the forearm or foot so that in the anatomical position the palm or sole is facing anteriorly (supination) or posteriorly (pronation). For example, if a person is holding a bowl of soup in one hand, the hand is "supinated" and the thumb will point away from the body midline and the palm will be ...
The brachioradialis is a stronger elbow flexor when the forearm is in a midposition between supination and pronation at the radioulnar joint. When pronated, the brachioradialis is more active during elbow flexion since the biceps brachii is in a mechanical disadvantage.
Standard anatomical terms of location are used to describe unambiguously the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on.
The foot (pl.: feet) 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 [clarification needed] organ at the terminal part of the leg made up of one or more segments or bones, generally including claws and/or nails.

[6]: 123 Inversion occurs at the subtalar joint and transverse tarsal joint. [7] Eversion of the foot occurs at the subtalar joint. The muscles involved in this include fibularis longus and fibularis brevis, which are innervated by the superficial fibular nerve. Some sources also state that the fibularis tertius everts. [6]: 108
