[2] [16] Lateral (from Latin lateralis ' to the side ') describes something to the sides of an animal, as in "left lateral" and "right lateral". Medial (from Latin medius ' middle ') describes structures close to the median plane, or closer to the median plane than another structure. [16] For example, in a human, the arms are lateral to the torso.
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 ...
Longitudinal – spanning the length of a body. Lateral – spanning the width of a body. The distinction between width and length may be unclear out of context. Adjacent – next to; Lineal – following along a given path. The shape of the path is not necessarily straight (compare to linear).
In human anatomy, the anatomical planes are defined in reference to a body in the standard anatomical position, the upright or standing orientation. [1]A transverse plane (also known as axial or horizontal plane) is parallel to the ground; it separates the superior from the inferior, or the head from the feet.
In addition, some segmented muscle groups, such as the lateral hypaxial musculature in the salamander are oriented at an angle to the longitudinal direction. For these obliquely oriented fibers the strain in the longitudinal direction is greater than the strain in the muscle fiber direction leading to an architectural gear ratio greater than 1.
The longitudinal fissure plays a key role in corpus callosotomy, neurosurgery resulting in split brain, as it provides unobstructed access to the corpus callosum. Corpus callosotomy is one of the procedures used for pharmacologically treating intractable epilepsy cases, and it consists of the division of the nerve fibers running between the two ...
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.
Longitudinal axis may refer to: In anatomy, going from head to tail; see Anatomical terms of location § Axes; In aviation, nose to tail of a plane; see Aircraft principal axes § Longitudinal axis (roll) In geography, an imaginary line passing through the centroid of the cross sections along the long axis of an object
