axial length of the eye axial length of the eye. length of the eye, axial. The distance between the anterior and posterior poles of the eye. In vivo, it is measured either by ultrasonography or by partial coherence interferometry (PCI). These measurements represent the distance between the anterior pole and Bruch's membrane.

Summary 1 A coronal or frontal plane is perpendicular to the ground and divides the body into dorsal (posterior or back) and ventral (anterior or front) portions. 2  A transverse plane, also known as an axial plane or cross-section, divides the body into cranial (head) and caudal (tail) portions.ovement at the joint take place in a plane about an axis. There are three axis of rotation. 1  Sagital axis-passes horizontally from posterior to anterior and is formed by the intersection of the sagital and transverse planes.

Transverse plane For the planes of a gear, see List of gear nomenclature. The transverse plane (also called the horizontal plane, axial plane, or transaxial plane) is an imaginary plane that divides the body into superior and inferior parts. It is perpendicular to the coronal and sagittal planes.he transverse plane (also called the horizontal plane, axial plane, or transaxial plane) is an imaginary plane that divides the body into superior and inferior parts.

Radial Internal Clearance Radial clearance is the play between the ball and raceway perpendicular to the bearing axis. Axial clearance is the play parallel to the bearing axis and is typically at least 10 times greater than the radial clearance.Generally, internal radial clearance will be reduced 80% of the interference fit amount.nternal clearance is the play within a ball bearing. It is the geometrical clearance between the inner ring, outer ring and ball. It is a critical factor in bearing selection that will directly impact bearing life.

What's the difference between radial and axial and what are some good examples of each? Axial means along or parallel to the axis of a body/member/object. Consider a straight pipe, here if you flow water, then the direction of flow of water is 'AXIAL'. In case of loading, say a electric pole, here the weight of electric cable and pol...

Cervical length In obsteric and gynaecological imaging, the cervical length (CL) is defined as the length between the internal cervical os and the external cervical os. the cervical length is most accurately assessed on a transvaginal scan with an empty bladder. in a normal gravid situation the cervical length is considered to be at least 30 mm (3 cm) the presence of a full bladder can increase the cervical length particularly on a trans-abdominal scan.

- The key advantage of the axial design is that the cylinders are arranged in parallel around the output/crank shaft rather than at 90 degrees as in crankshaft engines. As a result, it is a very compact, cylindrical engine, allowing variation in compression ratio of the engine while running.

Axial tilt Axial tilt. In astronomy, axial tilt, also known as obliquity, is the angle between an object's rotational axis and its orbital axis, or, equivalently, the angle between its equatorial plane and orbital plane. It differs from orbital inclination. At an obliquity of zero, the two axes point in the same direction; i.e., the rotational axis is perpendicular to the orbital plane. Earth's obliquity oscillates between 22.1 and 24.5 degrees on a 41,000-year cycle; the earth's mean obliquity is currently 23°26 ...

What is the angular inclination of the Earth's rotational axis relative to its solar orbital plane? The Earth has an axial tilt of about 23° 27’. The axis is tilted in the same direction throughout a year; however, as the Earth orbits the Sun, the hemisphere (half part of earth) tilted away from the Sun will gradually come to be tilted towards the Sun, and vice versa.
