The shape of the T wave is usually asymmetrical with a rounded peak. T wave inversions from V2 to V4 leads are frequently found and normal in children. In normal adults, T wave inversions from V2 to V3 are less commonly found but can be normal. [4] The depth of the T wave also becomes progressively shallow from one to the next lead. [5]
The human Y chromosome showing the SRY gene which codes for a protein regulating sexual differentiation. Sexual differentiation in humans is the process of development of sex differences in humans. It is defined as the development of phenotypic structures consequent to the action of hormones produced following gonadal determination. [1]

Human reproduction is sexual reproduction that results in human fertilization to produce a human offspring. It typically involves sexual intercourse between a sexually mature human male and female. [1] During sexual intercourse, the interaction between the male and female reproductive systems results in fertilization of the ovum by the sperm to ...
The T wave inversion in V1-4 and a marked Q wave in III occur; these changes are characteristic for Ebstein's anomaly and do not reflect ischemic ECG changes in this patient. Other abnormalities that can be seen on the ECG include: signs of right atrial enlargement or tall and broad 'Himalayan' P waves
A breech birth is when a baby is born bottom first instead of head first, as is normal. [1] Around 3–5% of pregnant women at term (37–40 weeks pregnant) have a breech baby. [2] Due to their higher than average rate of possible complications for the baby, breech births are generally considered higher risk. [3]
Folliculogenesis is continuous, meaning that at any time the ovary contains follicles in many stages of development. The majority of follicles die and never complete development. A few develop fully to produce a secondary oocyte which is released by rupture of the follicle in a process called ovulation.
Sex assignment (also known as gender assignment[ 1 ][ 2 ]) is the discernment of an infant's sex, typically made at birth based on an examination of the baby's external genitalia by a healthcare provider such as a midwife, nurse, or physician. [ 3 ] In the vast majority of cases (99.95%), sex is assigned unambiguously at birth.
