Asymmetry in the Sylvian fissure (also known as the lateral sulcus), which separates the frontal and parietal lobes from the temporal lobe, was one of the first incongruencies to be discovered. Its anatomical variances are related to the size and location of two areas of the human brain that are important for language processing, Broca's area ...
The Yakovlevian torque [25] (a.k.a. "counterclockwise brain torque" [28] refers to an anatomical peculiarity of the normal brain. On average, the frontal lobes are asymmetric to the left (the right lobe appears slightly larger than the left), whereas the occipital lobe is asymmetric to the right; the central sulcus and temporal lobe of the ...
English: The aurofacial asymmetry is the asymmetry of the eyes, nose and mouth with respect to the median plane between the ears, and was predicted by the Axial Twist Theory. (A) The average face from N = 200 (Blanz & Vetter, 1999; Troje & Bülthoff, 1996) with the tragus of the ears aligned with the horizontal axis of the im- age plane.
Reference charts for adult head circumference also generally feature homogeneous samples and fail to take height and weight into account. [ 6 ] One study in the United States estimated the average human head circumference to be 57 centimetres ( 22 + 1 ⁄ 2 in) in males and 55 centimetres ( 21 + 3 ⁄ 4 in) in females.

The adult human brain weighs on average about 1.2–1.4 kg (2.6–3.1 lb) which is about 2% of the total body weight, [2] [3] with a volume of around 1260 cm 3 in men and 1130 cm 3 in women. [4] There is substantial individual variation, [ 4 ] with the standard reference range for men being 1,180–1,620 g (2.60–3.57 lb) [ 5 ] and for women ...
Assessment of the skull from a top view shows asymmetry of the frontal bones, an increased width of the skull and a forward displacement of the ear at the ipsilateral side of the head. [12] Assessment of the skull from a frontal view will show asymmetrical features of the face, including a displacement of the chin point of the jaw and a ...
The standard definition of a reference range for a particular measurement is defined as the interval between which 95% of values of a reference population fall into, in such a way that 2.5% of the time a value will be less than the lower limit of this interval, and 2.5% of the time it will be larger than the upper limit of this interval, whatever the distribution of these values.
