Neurotransmitter(AP)
several specific ones
| Question | Answer |
|---|---|
| Acetylcholine (ACh) | Common; Involved in muscle action. Too much causes spasms. Too little paralysis. Alzheimer's |
| Dopamine | Involved in many behaviors and emotions. Imbalance Schizophrenia and Parkinson's |
| Serotonin | Involved in sleep and depression |
| Norepinephrine | "Fight or Flight" arousal |
| Endorphins | Pain inhibitors "Runners High" |
| Glutamate | Long-term memory, pain threshold |
| GABA (Gamma aminobutyric acid) | Imbalance Sleep and eating disorders Inhibitory neurotransmitter. Brain deterioration |
| Glycene | Involved in inhibition of spinal cord and lower brain |
| Broca's area | production of speech, affects ability to speak |
| Wernicke's area | understanding of spoken or written language, affects language comprehension |
| CAT scan Computerized Axial Tomography | \creates 3d images of a brain without surgery |
| MRI Magnetic Resonance Imaging | more successful, captures images of ridges, fissures, and folds in the brain |
| EEG | electrodes on either side of brain measure brain activity by millisecond. |
| Somatic Nervous System | branch of Peripheral Nervous system, composed of all afferent and efferent neurons |
| Autonomic Nervous System | comprises of neurons that carry messages between central nervous system and internal organs of the body(heart, digestive) |
| Afferent neurons | sensory, info to the central nervous |
| Efferent neurons | motor, central nervous to skeletal muscles |
| Sympathetic division | carry message "ALERT" "fight or Flight" |
| Parasympathetic division | Calms and relaxes the body |
| Hormones | similar to neurotransmitters, travel in blood move slower. Chemicals can be both NTs and hormones |
| Thyroid gland | secretes thyroxin, regulates metabolism and how alert or energetic you are. |
| Parathyroids | balance levels of calcium and phosphate, influence levels of excitability |
| Pineal gland | secretes melatonin, which regulates sleep-wake cycles. |
| Pancreas | controls blood sugar level with insulin and glucagon. Less insulin too much sugar. More Insulin too little sugar. |
| Pituitary gland | master hormone secreter aids in all endocrine functions |
| Gonads | reproductive glands, testes and ovaries |
| Adrenal glands | affect body's reaction to stress. stimulated by autonomic nervous system. pours hormones into bloodstream. |
| Chromosomes | threadlike bodies in cell contain genes |
| Genes | control the transmission of traits; found on the chromosomes. |
| strain studies | study of heritability of behavioral traits using animals that have been inbred to produce strains that are genetically similar to one another. |
| Selection Studies | Studies estimate the heritability of a trait by breeding animals with other animals that have the same trait. |
| Family Studies | Studies of heritability in humans based on assumption that if genes influence a certain trait, close relatives should be more similar than others. |
| Twin Studies | Study of twins to determine relative of hereditary and environment on human behavior. |
| Adoption Studies | study on adopted children to observes relative influence of hereditary and environment on human behavior. |
| Curare, LSD, Atrophe | Occupy or block receptor sites |
| Amphetamines | Increase the release of a neurotransmitter |
| Antidepressants | Like Prozac; Interfere with the reabsorption of neurotransmitter |
| Polarized neuron | c(at rest)harge inside is negative relative to outside |
