  2. Human skeletal changes due to bipedalism - Wikipedia

    en.wikipedia.org/wiki/Human_skeletal_changes_due...

    Without the lumbar curve, the vertebral column would always lean forward, a position that requires much more muscular effort for bipedal animals. With a forward bend, humans use less muscular effort to stand and walk upright. [15] Together the lumbar and thoracic curves bring the body's center of gravity directly over the feet. [7]

  3. Bipedalism - Wikipedia

    en.wikipedia.org/wiki/Bipedalism

    Most bipedal animals move with their backs close to horizontal, using a long tail to balance the weight of their bodies. The primate version of bipedalism is unusual because the back is close to upright (completely upright in humans), and the tail may be absent entirely. Many primates can stand upright on their hind legs without any support.

  4. Astasia-abasia - Wikipedia

    en.wikipedia.org/wiki/Astasia-abasia

    Astasia-abasia refers to the inability to either stand or walk in a normal manner. Astasia refers to the inability to stand upright unassisted. Abasia refers to lack of motor coordination in walking. The term abasia literally means that the base of gait (the lateral distance between the two feet) is inconstant or unmeasurable.

    en.wikipedia.org/wiki/Anatomical_terms_of_location

    Different terms are used for groups of creatures with different body layouts, such as bipeds (creatures that stand on two feet, such as humans) and quadrupeds. [1] The reasoning is that the neuraxis is different between the two groups, and so is what is considered the standard anatomical position , such as how humans tend to be standing upright ...

    en.wikipedia.org/wiki/Orthograde_posture

    From fossil evidence and hypotheses state that upright posture was a quintessential reaction to changes in environment and competition. Due to the more wooded barren savannahs of northern Africa, O. tugenensis and australopiths began to change, which is evident in morphological data accumulated from the remains of the different species.

  8. Orthostatic intolerance - Wikipedia

    en.wikipedia.org/wiki/Orthostatic_intolerance

    Orthostatic intolerance occurs in humans because standing upright is a fundamental stressor, so requires rapid and effective circulatory and neurologic compensations to maintain blood pressure, cerebral blood flow, and consciousness. When a human stands, about 750 ml of thoracic blood are abruptly translocated

  9. Astasis - Wikipedia

    en.wikipedia.org/wiki/Astasis

    Astasis is a lack of motor coordination marked by an inability to stand, walk or even sit without assistance due to disruption of muscle coordination. The term astasia is interchangeable with astasis and is most commonly referred to as astasia in the literature describing it. Astasis is the inability to stand or sit up without assistance in the ...
