PSYB64H3 Chapter Notes - Chapter 10: Otoacoustic Emission, Posterior Pituitary, Real Sex
Document Summary
X chromosome from mother to all their offspring; 2 x = female. Y chromosome from father (with an x); 1 x & 1 y = male. Single chromosome (xo) instead of xx or xy. 1 in 2500 live births lack of 2nd sex chromosome = impact on fertility. Growth, and hormone production and is associated with higher risk of diabetes, osteoporosis, and cardiovascular disease. Have normal female external genitalia but ovaries develop abnormally (from unidentified regions on x chromosomes and having a single x interferes) Specific deficits in spatial relationships and memory. Human growth hormone, female hormone replacement therapy, etc: klinefelter syndrome. Male but reduced fertility and require hormone treatment at puberty to promote the development of secondary male sex characteristics (facial hair, deeper voice, development of external genitalia) and to inhibit female characteristics such as breast development. Due to interference with the process of x-inactivation in which one x chromosome in each female cells is randomly silenced.
