Study Notes
Cellular Processes
- Diffusion is a form of transport in cells
- Enzymes catalyze metabolic reactions, including catabolic (breakdown) and anabolic (synthesis) reactions
Nervous System
- Divided into Central Nervous System (brain and spine) and Peripheral Nervous System (nerves)
- Nerve cells: sensory neurons (receive stimuli), connecting neurons (integration), and motor neurons (response)
- Synapses: gaps between neurons, neurotransmitters transmit signals
- Brain structures and functions: control center for body, processing and integrating information
- Receptors: detect stimuli (e.g., sensory receptors in skin)
- Effectors: respond to stimuli (e.g., muscles, glands)
Reflex Arcs and Endocrine System
- Reflex arcs: automatic responses to stimuli, involving sensory neurons, interneurons, and motor neurons
- Endocrine system: glands produce hormones, regulating body functions
- Pituitary gland: master gland, regulates other endocrine glands
- Adrenal glands: produce adrenaline, regulate stress response
- Ovaries and testes: produce sex hormones
Hormones and Homeostasis
- Hormones: chemical messengers, travel through bloodstream, detected by target cells
- Homeostasis: maintaining internal balance, using stimulus-response model and feedback
- Temperature control: thermoregulation, maintaining body temperature
Psychology
- Definition: scientific study of behavior and mental processes
- Overt behavior: observable, external actions
- Covert behavior: internal, mental processes
- Sports psychologists: enhance performance, overcome obstacles
- Forensic psychologists: apply psychology to law, justice, and policy
- 9 fields of psychology: clinical, counseling, school, industrial-organizational, social, developmental, cognitive, neuroscience, and personality
- Roles: research, assessment, intervention, consultation, education
Memory and Taste
- Memory process: encoding, storage, retrieval
- Sensory memory: brief, immediate, raw data
- Short-term memory: limited capacity, short duration
- Long-term memory: permanent storage, large capacity
- Ways to improve memory: repetition, organization, association, visualization
- Taste buds: located on tongue, detect 5 basic flavors (sweet, sour, salty, bitter, umami)
- Influences on taste perception: temperature, texture, smell, expectations
- Cones and rods: photoreceptors in retina, detecting light and color
