Study Notes
Genes and Chromosomes
- Humans begin life as a single cell called a zygote, formed by the fusion of an ovum and a sperm
- The zygote contains over 2 billion coded messages that guide the development of a human
- Genes are specific sequences of DNA
- Chromosomes are rod-shaped portions of DNA, arranged in 23 pairs
- Each chromosome contains genetic instructions for an individual
- Chromosomes replicate via mitosis
Multiple Births
- Multiple births occur in two types: monozygotic (identical) and dizygotic (fraternal)
- Fertility drugs can increase the likelihood of multiple births
- Racial, ethnic, and national differences also play a role in the incidence of multiple births
Mixing and Matching Genes
- Dominant traits are expressed, while recessive are unexpressed
- Genotype refers to the combination of genetic material present, but is not outwardly visible
- Phenotype is the observable trait, the one that is actually seen
Sickle-Cell Anemia
- Sickle-cell anemia is a blood disorder affecting the shape of red blood cells
- Symptoms include poor appetite, stunted growth, swollen stomach and yellowish eyes
Inherited and Genetic Disorders
- Fragile X syndrome is characterized by an X chromosome that is susceptible to damage, which can cause intellectual limitations
- Sickle-cell anemia is a blood disorder affecting the shape of red blood cells
Genetic and Environmental Influences on Personality
- Neuroticism and extroversion are two of the “Big Five” personality traits linked to genetic factors
- The other three “Big Five” personality traits are:
- Contentiousness
- Openness
- Agreeableness
Malnutrition
- Malnutrition is a condition of having an improper amount and balance of nutrients
- It is more common in children living in developing countries
- Malnutrition can lead to slower growth rates and lower IQ scores
Severe Malnutrition
- Marasmus is a severe form of malnutrition, occurring during the first year of life, characterized by wasting away
- Kwashiorkor affects older children, characterized by swelling of the stomach, limbs and face
Obesity in Infancy
- While links between infant obesity and later obesity are not fully established, focus should be placed on appropriate nutrition
Eating Disorders
- Anorexia Nervosa is characterized by refusal to eat and denial of the impact on appearance
- Bulimia is characterized by binge eating followed by purging
- Both disorders are more common in females
Other Sexually Transmitted Infections
- Trichomoniasis is a vaginal or penile infection caused by a parasite, leading to discharge
- Chlamydia is a bacterial infection that can cause burning urination and discharge, with a risk of pelvic inflammation and sterility
- Genital herpes is a viral infection that can cause genital sores and is contagious
Facets of Addiction
- Biological addiction is characterized by physical dependence on drugs, leading to changes in the nervous system
- Psychological addiction is characterized by reliance on drugs to cope with stress, preventing individuals from addressing underlying issues
Adult Preventive Health-Care Screening Recommendations
- Breast self-exams should be conducted monthly after age 40
- Mammograms are recommended annually after age 40
- Pap smears are recommended every 2 to 3 years after 3 normal tests in a row, unless at special risk
- Pelvic exams are recommended annually if ovaries remain after hysterectomy
Introducing Solid Foods
- Solids can be introduced at 6 months but are not needed until 9 to 12 months
- Cereal and strained fruits are generally the first solids introduced
- Weaning time varies across countries
Benefits of Adequate Nutrition
- Social and emotional functioning benefits include:
- More peer involvement
- More positive emotions
- Less anxiety
- More eagerness to explore new environments
- More persistence in frustrating situations
- Generally higher energy levels
The Benefits of Exercise
- Physical activity throughout life provides numerous benefits, including improved health and well-being
Breastfeeding
- Breast milk provides all the nutrients infants need for the first 12 months of life
- It is easier to digest than alternatives, provides immunity to diseases, and enhances cognitive growth
- Breastfeeding offers significant emotional advantages for mother and child
- However, it is not a cure-all for infant nutrition and health
