Document Summary
Absolute refractory period (82): is the minimum length of time after an action potential during which another action potential cannot begin. The downtime is only one or two milliseconds. Action potential (82): a very brief shift in a neurons electric charge that travels along an axon. Action potential is an all or nothing event. Adaption (119): is an inherited characteristic that increased in a population through natural selection because it helped solve a problem of survival or reproduction during the time it emerged. Adoption studies (115): assess hereditary influence by examining the resemblance between adopted children and both their biological and their adoptive parents. Afferent nerve fibres (90): are axons that carry information inward to the central nervous system from the periphery of the body. This is how sensory information is carried from your eyes to your brain. Agonist (87): is a chemical that mimics the action of a neurotransmitter.
