In the axial plane, the caudate lobe should normally have a cross-section of less than 0.55 of the rest of the liver. [2] Other ultrasound studies have suggested hepatomegaly as being defined as a longitudinal axis > 15.5 cm at the hepatic midline, or > 16.0 cm at the midclavicular line. [17] [18]
Hepatomegaly: Medical imaging: Longitudinal axis > 15.5 cm at the hepatic midline, or > 16.0 cm at the midclavicular line [14] Autopsy: Weight over upper limit of standard reference range, of 1,860 g (4.10 lb) in men [12] and 1,770 g (3.90 lb) in women. [13] Lymph nodes: Lymphadenopathy: Generally 10 mm [15] [16
CT scan showing an adult liver in the axial plane Organogenesis , the development of the organs, takes place from the third to the eighth week during embryogenesis . The origins of the liver lie in both the ventral portion of the foregut endoderm (endoderm being one of the three embryonic germ layers ) and the constituents of the adjacent ...
The foliations are symmetrically arranged with respect to the axial plane, depending on the composition and competency of a rock. For example, when mixed sandstone and mudstone sequences are folded during very-low to low grade metamorphism, cleavage forms parallel to the fold axial plane, particularly in the clay-rich parts of the sequence. In ...
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.
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 ...
The axial surface is defined as a plane connecting all the hinge lines of stacked folded surfaces. If the axial surface is planar, it is called an axial plane and can be described in terms of strike and dip. Folds can have a fold axis.
The median plane, which divides the body into left and right. [2] [6] This passes through the head, spinal cord, navel, and, in many animals, the tail. [6] The sagittal planes, which are parallel to the median plane. [1] The frontal plane, also called the coronal plane, which divides the body into front and back. [2]
