Axial parallelism of Saturn's rings, in a 17th century work by James Ferguson (Scottish astronomer) Axial parallelism can be seen in the Moon's tilted orbital plane.This results in the revolution of the lunar nodes relative to the Earth, causing an eclipse season approximately every six months, in which a solar eclipse can occur at the new moon phase and a lunar eclipse can occur at the full ...
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. The transverse planes identified in Terminologia Anatomica are the transpyloric plane , the subcostal plane , the transumbilical (or umbilical) plane , the supracristal plane , the ...
"Ventral" in the central nervous system also refers to the rostro-caudal axis, which changes within the head. These three axes of the human brain match the three planes within which they lie, even though the terms for the planes have not been changed from the terms for the bodily planes. The most commonly used reference planes are:
It was decided that a plane passing through the inferior margin of the left orbit (the point called the left orbitale) and the superior margin of each ear canal or external auditory meatus, a point called the porion, was most nearly parallel to the surface of the earth at the position the head is normally carried in the living subject.

The frontal plane, also called the coronal plane, which divides the body into front and back. [2] The horizontal plane, also known as the transverse plane, which is perpendicular to the other two planes. [2] In a human, this plane is parallel to the ground; in a quadruped, this divides the animal into anterior and posterior sections. [3]
The head of a muscle, also called caput musculi is the part at the end of a muscle at its origin, where it attaches to a fixed bone. Some muscles such as the biceps have more than one head. Insertion
When it comes to semiconductor stocks, it's virtually impossible not to think of Nvidia.Over the last two years, the company has become the undisputed leader among chip stocks, and with that, is ...
The parallel muscle architecture is found in muscles where the fibers are parallel to the force-generating axis. [1] These muscles are often used for fast or extensive movements and can be measured by the anatomical cross-sectional area (ACSA). [3] Parallel muscles can be further defined into three main categories: strap, fusiform, or fan-shaped.
