Study Notes
Nervous System Overview
- The nervous system regulates internal functions and external reactions.
- Comprises two main parts: central nervous system (CNS) and peripheral nervous system (PNS).
Neurons and Their Structure
- Neurons consist of three main parts: cell body, axon, and dendrites.
Central Nervous System
- The central nervous system is made up of the brain and spinal cord.
- The spinal cord transmits messages and is involved in spinal reflexes.
Autonomic vs. Somatic Nervous System
- The autonomic nervous system regulates involuntary muscles and internal organs.
- The somatic nervous system governs voluntary muscles and sense organs.
Sympathetic and Parasympathetic Systems
- The sympathetic nervous system prepares the body for emergencies.
- The parasympathetic nervous system promotes calm after emergencies.
Brain Sections and Functions
- The hindbrain controls functions like heart rate and blood pressure.
- The midbrain is responsible for processing vision and hearing.
- The forebrain manages complex processes, including emotions.
Cerebrum and Brain Connectivity
- The cerebrum contains the cerebral cortex, linked to thinking, language, memory, and perception.
- The corpus callosum connects the brain's hemispheres, facilitating information transfer.
Brain Imaging Techniques
- Imaging techniques like CAT scans offer three-dimensional views of the brain.
Endocrine System and Hormones
- The endocrine system comprises glands secreting hormones affecting body functions and behavior.
- The pituitary gland is known as the "master gland" due to its wide-ranging hormonal influences.
Sex Hormones
- Testosterone is the male hormone promoting the development of secondary sex characteristics.
- Estrogen aids in female secondary characteristics, while progesterone prepares the body for pregnancy.
Heredity and Behavior
- Heredity involves the transmission of characteristics from parents to offspring.
- The nature-nurture debate explores the impact of biology versus environment on psychological traits.
Research Methods in Heredity
- Identical twins studies help determine the roles of heredity and environment in traits.
- Similarities noted in twins raised apart are attributed to genetic factors.
Biological Psychologist's Focus Areas
- Four major study areas: nervous system, endocrine system, environment, and heredity.
- The peripheral nervous system comprises the somatic and autonomic nervous systems.
Endocrine System Components
- Major components include adrenal gland, thyroid gland, pituitary gland, testes, and ovaries.
Environmental Influences
- Environment influences behavior through family, education, culture, living conditions, and experiences.
Heredity's Impact
- Heredity affects physical appearance and psychological traits.
- Genetic information is carried by genes located in chromosomes.
