Study Notes
Autonomic Nervous System (ANS)
- Regulates the glands and muscles of internal organs.
- Comprised of sympathetic and parasympathetic divisions.
Endocrine System
- Consists of ductless glands releasing hormones into the bloodstream.
- Hormones regulate homeostasis, growth, metabolism, and behaviors.
Key Glands
- Pituitary Gland: Known as the "master gland," it secretes hormones like growth hormone and prolactin.
- Hypothalamus: Acts as the "commander" to the pituitary gland, regulating its functions.
- Pineal Gland: Secretes melatonin, which affects the sleep-wake cycle.
Thyroid Gland
- Produces thyroxin, crucial for metabolism.
- Deficiencies linked to hypothyroidism and cretinism; excess leads to hyperthyroidism.
Adrenal Glands
- Located above the kidneys, they secrete corticosteroids enhancing stress resistance and muscle growth.
- Sympathetic ANS triggers the release of epinephrine and norepinephrine during stressful situations, intensifying emotions like fear.
Nature vs. Nurture
- Nature: Refers to the inborn characteristics of an organism.
- Nurture: Encompasses environmental influences shaping behaviors.
Biopsychosocial Model
- Integrates biological, psychological, and social factors in understanding human behavior.
Evolution and Heredity
- Charles Darwin's Theory: Proposes natural selection whereby adaptive genetic variations enhance survival and reproduction.
- Humanity, like all species, evolves and adapts over time.
Evolutionary Psychology
- Examines links between adaptation, natural selection, and psychological processes.
- Suggests psychological traits may also undergo natural selection like physical traits.
Heredity and Genetics
- Heredity: Biological transfer of traits from parents to offspring through genes.
- Genes: Basic units of heredity located on chromosomes.
- Genetics: Subfield of biology focused on heredity.
- Behavioral Genetics: Studies how genetic transmission influences behavior patterns.
Key Terms
- Gene: Basic unit of heredity on chromosomes.
- Chromosomes: Structures containing genes; humans have 46 in 23 pairs.
- DNA: Substance forming chromosomes, carrying genetic information.
Genotypes and Phenotypes
- Polygenic Traits: Influenced by multiple genes, relevant in psychological characteristics.
- Genotype: An individual's genetic makeup.
- Phenotype: Observable characteristics shaped by genotype and environment.
Epigenetics
- Studies changes in gene function due to environmental factors.
- Examples include studies on trauma effects and nutritional impacts on health.
Kinship Studies
- Compare genetic influences on behaviors in related versus unrelated individuals.
Twin Studies
- Monozygotic (MZ) Twins: Identical twins sharing the same genetic code.
- Dizygotic (DZ) Twins: Fraternal twins, as genetically similar as regular siblings.
Nervous System Overview
- Controls processes like thought, heart rate, and coordination.
- Consists of the Central Nervous System (CNS) and Peripheral Nervous System (PNS).
Divisions of the Nervous System
- CNS: Composed of the brain and spinal cord.
- PNS: Contains sensory and motor neurons, subdivided into somatic (voluntary movements) and autonomic (involuntary responses).
Central Nervous System Components
- Spinal Cord: Transmits messages between the body and brain; responsible for reflex actions.
- Grey Matter: Contains unmyelinated neurons; involved in basic reflexes.
- White Matter: Composed of myelinated neurons; facilitates communication to and from the brain.
