The central line of the bundle represents the chief ray. The same holds for object point B {\displaystyle B} and its retinal image at b {\displaystyle b} . The visual angle V {\displaystyle V} is the angle between the chief rays of A {\displaystyle A} and B {\displaystyle B} .
The internal human body includes organs, teeth, bones, muscle, tendons, ligaments, blood vessels and blood, lymphatic vessels and lymph. The study of the human body includes anatomy, physiology, histology and embryology. The body varies anatomically in known ways.

Human physiology is the study of how the human body's systems and functions work together to maintain a stable internal environment. It includes the study of the nervous, endocrine, cardiovascular, respiratory, digestive, and urinary systems, as well as cellular and exercise physiology.
Regarding posture, a pronated foot is one in which the heel bone angles inward and the arch tends to collapse. Pronation is the motion of the inner and outer ball of the foot with the heel bone. [13] One is said to be "knock-kneed" if one has overly pronated feet. It flattens the arch as the foot strikes the ground in order to absorb shock when ...
Muscle architecture is the physical arrangement of muscle fibers at the macroscopic level that determines a muscle's mechanical function. There are several different muscle architecture types including: parallel, pennate and hydrostats.
When viewed at large angles from the side, the iris and pupil may still be visible by the viewer, indicating the person has peripheral vision possible at that angle. [15] [16] [17] About 15° temporal and 1.5° below the horizontal is the blind spot created by the optic nerve nasally, which is roughly 7.5° high and 5.5° wide. [18]
Human anatomy, physiology, and biochemistry are basic medical sciences, which are generally taught to medical students in their first year at medical school. Human anatomy can be taught regionally or systemically; [ 1 ] that is, respectively, studying anatomy by bodily regions such as the head and chest, or studying by specific systems, such as ...
