20 Cards in this Set

  • Front
  • Back
Influences movement, learning, attention, and emotion
Affects mood, hunger, sleep, and arousal
Helps control alertness and arousal
GABA (gamma-aminobutyric acid)
A major inhibitory neurotransmitter
A major excitatory neurotransmitter; involved in memory
nervous system
the body's speedy, elctrochemical communication system, consisting of all the nerve cells of the peripheral and central nervous system
Central Nervous System (CNS)
the brain and the spinal cord
Peripherial Nervous System (PNS)
the sensory and motor neurons that connect the central nervous system to the rest of the body.
neural "cables" containing many axons. These bundled axons, which are part of the peripherial nervous system connect the central nervous system with muscles, glands, and sense organs.
Sensory Neurons
neurons that carry incoming information from the sense receptors to the central nervous system.
Central nervous system neurons that internally communicate and intervene between the sensory inputs and motor outputs
Motor Neurons
neurons that carry outgoing information from the central nervous system to the muscles and glands
Somatic Nervous System
the division of the peripheral nervous system that controls the body's skeletal muscles. Also called the Skeletal Nervous System
Autonomic Nervous System
the part of the peripheral nervous system that controls the glands and the muscles of the internal organs(such as the heart). Its sympathetic division arouses;its parasympathetic division calms.
Sympathetic Nervous System
the division of the autonomic nervous system that arouses the body, mobilizing its energy in stressful situations.
Parasympathetic Nervous System
the division of the autonomic nervous system that calms the body, conserving its energy.
a simple, automatic, inborn, response to a sensory stimulus, such as the knee jerk response
Neural Networks
interconnected neural cells. With experience, networks can learn, as feedback strengthens or inhibits connections that produce certain results. Computer sims of neural networks show analogous learning
the body's "slow" chemical communication system:a set of glands that secrete hormones into the bloodstream
chemical messengers, mostly those manufactured by the endocrine glands, that are produced in one tissue and affect another.
