  2. Anatomical terms of location - Wikipedia

    en.wikipedia.org/wiki/Anatomical_terms_of_location

    This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal.

  3. Transverse plane - Wikipedia

    en.wikipedia.org/wiki/Transverse_plane

    The transverse plane (also known as the horizontal plane, axial plane and transaxial plane) is an anatomical plane that divides the body into superior and inferior sections. [1] It is perpendicular to the coronal and sagittal planes.

  4. Anatomical plane - Wikipedia

    en.wikipedia.org/wiki/Anatomical_plane

    Early inductive effects of the axial mesoderm upon the overlying neural ectoderm is the mechanism that establishes the length dimension upon the brain primordium, jointly with establishing what is ventral in the brain (close to the axial mesoderm) in contrast with what is dorsal (distant from the axial mesoderm). Apart from the lack of a causal ...

  5. Anatomical terms of neuroanatomy - Wikipedia

    en.wikipedia.org/wiki/Anatomical_terms_of_neuro...

    Axial or "transverse" or "horizontal", the plane that is horizontal and parallel to the ground with the body standing in the standard anatomical position. It contains (and thus is defined by) the lateral and the medial axes of the brain.

  6. Anatomical terminology - Wikipedia

    en.wikipedia.org/wiki/Anatomical_terminology

    This position is one in which a person is standing, feet apace, with palms forward and thumbs facing outwards. [11] Just as maps are normally oriented with north at the top, the standard body "map", or anatomical position, is that of the body standing upright, with the feet at shoulder width and parallel, toes forward.

  7. Coronal plane - Wikipedia

    en.wikipedia.org/wiki/Coronal_plane

    The coronal plane is an example of a longitudinal plane.For a human, the mid-coronal plane would transect a standing body into two halves (front and back, or anterior and posterior) in an imaginary line that cuts through both shoulders.

  8. Sagittal plane - Wikipedia

    en.wikipedia.org/wiki/Sagittal_plane

    Coronal axis, medial-lateral axis, or frontal axis is the axis perpendicular to the sagittal plane, i.e., the one formed by the intersection of the coronal and the transversal planes. [8] Extension and flexion are the movements of limbs within the sagittal plane. [9] Abduction and adduction are terms for movements of limbs within the coronal ...

  9. Axis (anatomy) - Wikipedia

    en.wikipedia.org/wiki/Axis_(anatomy)

    In anatomy, the axis (from Latin axis, "axle") is the second cervical vertebra (C2) of the spine, immediately inferior to the atlas, upon which the head rests. The spinal cord passes through the axis. The defining feature of the axis is its strong bony protrusion known as the dens, which rises from the superior aspect of the bone.
