Cards

Term
EEG - Electroencephalogram
Definition
A recording of the waves of electrical activity that sweep across the brains surface. Measured by electrodes placed on the scalp.
Term
PET scan - Positron Emission Tomography
Definition
A visual scan of brain activity that detects where a radioactive form of glucose goes while the brain performs a given task.
Term
MRI - Magnetic Resonance Imaging
Definition
A technique that uses magnetic fields and radio waves to produce computer generated images that distinguish amon different types of soft tissue; allow us to see structure within the brain.
Term
The control for heartbeat and breathing?
Definition
Medulla
Term
Neurons that carry incoming information from the sense receptors to the central nervous system.
Definition
Sensory Neurons
Term
Central nervous system neurons that internally communicate and intervene between sensory input and motor outputs.
Definition
Interneurons
Term
Neurons that carry outgoing information from the central nervous system to the muscles and glands.
Definition
Motor neurons
Term
The division of the peripheral nervous system that controls the bodies skeletal muscles.
Definition
Somatic nervous system
Term
The part of the peripheral nervous system that controls the glands and the muscles of the internal organs. Its sympathetic division arouses; its parasympathetic division calms.
Definition
Autonomic nervous system
Term
The division of the autonomic nervous system that arouses the body, mobilizing its energy in s tressful situations.
Definition
Sympathetic nervous system
Term
The division fo the autonomic nervous system that calms the body, conserving its energy.
Definition
Parasympathetic nervous system
Term
Psychology pertaining to how we view and effect one another.
Definition
Social psychology
Term
Study of the links between the brain and the mind.
Definition
Biological psychology
Term
Study and advice on behaviour in the workplace.
Definition
Industrial/orginizational psychology
Term
The study of our changing abilities from the 'womb to the tomb'.
Definition
Developmental psychology
Term
Experiementing with how we think, perceive, and solve problems.
Definition
Cognitive psychology
Term
Investigation of persistant personality traits.
Definition
Personality psychology
Term
Chemical messengers that traverse the synaptic gap between neurons; are released by sender neurons. Bind to the recepetor sites and influence whether or not neurons will generate a neural impulse.
Definition
Neurotransmitters
Term
The brain and the spinal cord form this system.
Definition
Central Nervous System (CRS)
Term
Neurons communicating with other neurons form the primary information system, otherwise known as the?
Definition
Nervous system
Term
What links the CRS with the bodies sense receptors, muscles and glands?
Definition
Peripheral Nervous System (PNS)
Term
"The master gland"
Definition
Pituitary
Term
Chemical messengers, mostly those manufactured by the endocrine glands, that are produced in one tissue and affect another.
Definition
Hormones
Term
A nerve cell; the basic building block of the nervous system.
Definition
Neuron
Term
The bushy, branching extensions of a neuron that receive messages and conduct impulses toward the cell body.
Definition
Dendrite
Term
The extension of a neuron, ending in the branching terminal fibers, through which messages pass to toher neurons ro to muscles or glands.
Definition
Axon
Term
The level of stimulation required to trigger a neural impulse.
Definition
Threshold
Term
The junction between the axon tip and of the sending neuron and the dendrite or cell body of the receiving neuron. The tiny gap at this junction is called the synaptic gap or cleft.
Definition
Synapse
Term
Natural opiates released in resonse to pain or vigorous exercise.
Definition
Endorphins
Term
Two sections of the nervous systems:
Definition
Central Nervous System
Peripheral Nervous System
Term
Two sections of the PNS:

Autonomic
Somatic
Term
Two sections of the Autonomic:
Definition
Sympathetic
Parasympathetic
Term
Three types of neurons:

Definition
Parasympathetic
Term
A set of glands that secrete hormones into the bloodstream.
Definition
Endocrine system
Term
The endocrine systems most influential gland:
Definition
Pituitary gland
Term
Biochemical units of heredity that make up the chromosomes
Definition
Genes
Term
Threadlike structures made of DNA particles that contain genes
Definition
Chromosomes
Term
The sex chromosomes found in both men and women.
Females = 2
Males = 1
Definition
X chromosomes
Term
The sex chromosome found only in men.
X + Y = male
Definition
Y chromosome
Term
Fertilized eggs
Definition
Zygotes
Term
The process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment.
Definition
Sensation
Term
The process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events.
