20 Cards in this Set

|
Dopamine
|
Influences movement, learning, attention, and emotion
|
|
|
Serotonin
|
Affects mood, hunger, sleep, and arousal
|
|
|
Norepinephrine
|
Helps control alertness and arousal
|
|
|
GABA (gamma-aminobutyric acid)
|
A major inhibitory neurotransmitter
|
|
|
Glutamte
|
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.
|
|
|
Nerves
|
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.
|
|
|
Interneurons
|
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.
|
|
|
Reflex
|
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
|
|
|
Endocrine
|
the body's "slow" chemical communication system:a set of glands that secrete hormones into the bloodstream
|
|
|
Hormones
|
chemical messengers, mostly those manufactured by the endocrine glands, that are produced in one tissue and affect another.
