Pigeon toe, also known as in-toeing, is a condition which causes the toes to point inward when walking.It is most common in infants and children under two years of age [1] and, when not the result of simple muscle weakness, [2] normally arises from underlying conditions, such as a twisted shin bone or an excessive anteversion (femoral head is more than 15° from the angle of torsion) resulting ...
Plantar reflex — in infants up to 1 year of age, a curling of the toes when something rubs the ball of the foot. Pupillary accommodation reflex — a reduction of pupil size in response to an object coming close to the eye. Pupillary light reflex — a reduction of pupil size in response to light.
The human foot evolved as a platform to support the entire weight of the body, rather than acting as a grasping structure (like hands), as it did in early hominids. Humans therefore have smaller toes than their bipedal ancestors. This includes a non-opposable hallux, which is relocated in line with the other toes. [7]
People sharing a meal in Uzbekistan. Eating positions vary in different regions of the world, as culture strongly influences the way people eat their meals. For example, in most of the Middle Eastern countries, eating while sitting on the floor is most common, and it is believed to be healthier than eating while sitting at a table. [8] [9]
A 2-D model of cortical sensory homunculus. A cortical homunculus (from Latin homunculus 'little man, miniature human' [1] [2]) is a distorted representation of the human body, based on a neurological "map" of the areas and portions of the human brain dedicated to processing motor functions, and/or sensory functions, for different parts of the body.
Skeletons of a human and an elephant. Comparative foot morphology involves comparing the form of distal limb structures of a variety of terrestrial vertebrates.Understanding the role that the foot plays for each type of organism must take account of the differences in body type, foot shape, arrangement of structures, loading conditions and other variables.
The primary advantages of a plantigrade foot are stability and weight-bearing ability; plantigrade feet have the largest surface area. The primary disadvantage of a plantigrade foot is speed. With more bones and joints in the foot, the leg is both shorter and heavier at the far end, which makes it difficult to move rapidly.
Foot growth continues to be very rapid in the first 5 years of life; slower development continues until skeletal maturity of the feet, which occurs on average at 13 years in girls and 15 years in boys. Final foot length is achieved before maximum height is reached in both genders. [1]
