Fundal height, or McDonald's rule, is a measure of the size of the uterus used to assess fetal growth and development during pregnancy. It is measured from the top of the mother's uterus to the top of the mother's pubic symphysis.
The process occurs from embryonic day 10 to 17 in mice and between gestational weeks seven to 18 in humans. [2] The cortex is the outermost layer of the brain and consists primarily of gray matter, or neuronal cell bodies. Interior areas of the brain consist of myelinated axons and appear as white matter.

The human brain is the central organ of the nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system ...
Fundi, sulci, and gyri in a section across a human brain. The deepest part of a sulcus, such as the sulci in the human cerebral cortex. [1] References
This may bring into question the effectiveness of brain development studies in treating and successfully rehabilitating criminal youth. [9] It's a common misconception to believe the brain stops development at any specific age. In the 2010s and beyond, science has shown that the brain continues to develop until at least 30 years of age. [10]
Gyrification in the human brain. Gyrification is the process of forming the characteristic folds of the cerebral cortex. [1] The peak of such a fold is called a gyrus (pl. gyri), and its trough is called a sulcus (pl. sulci). The neurons of the cerebral cortex reside in a thin layer of gray matter, only 2–4 mm thick, at the surface of the ...
Pachygyria is used to describe brain characteristics in association with several neuronal migration disorders; most commonly relating to lissencephaly. Lissencephaly ( smooth brain ) is a rare congenital brain malformation caused by defective neuronal migration during the 12th to 24th weeks of fetal gestation resulting in a lack of development ...
