| Question | Answer |
|---|---|
| Directionality | How body proportions change |
| Independence of Systems | Different parts of the body develop along different time tables. |
| Canalization | Development tends to follow and return to a normative course. |
| Norms | Average outcomes on a characteristic. |
| Individual Differences | Variation among individuals on a characteristic. |
| Central Nervous System (CNS) | Brain and Spinal Cord |
| Subcortical Structures | Brain components that control state of arousal |
| Limbic System | Manages emotions |
| Cortex | Layers of outer tissue that cover the brain |
| Association Areas | Awareness, attention, memory, and integration of information |
| Hemispheres | Two halves of the brain |
| Corpus Callosum | Connection between two hemispheres. |
| Visual Cortex | Sight |
| Auditory Cortex | Hearing |
| Sensorimotor Cortex | Touch |
| Motor Cortex | Voluntary Movement |
| Frontal Cortex | Thinking, planning, initiative, impulse control, and creativity. |
| Wernickes Area | Left side, language or speech comprehension |
| Brocas Area | Left side, language or speech production |
| Neurons | Cells that carry info across body and brain. |
| Dendrites | Branched extensions of neurons that act like antennas that pick up signals from other neurons. |
| Cell Body | Nucleus, biochemical mechanisms to keep cell alive and determine if cell will fire. |
| Axon | Part of cell that carries signals away from cell body toward other neurons. |
| Synapse | Connection between one neurons axon and another neurons dendrite. |
| Neurotransmitters | Electrochemicals through which neurons intercommunicate. |
| Action Potential | Electrical charge inside neuron. |
| Synaptogenesis | Development of connections between neurons through the growth of axons and dendrites. |
| Synaptic Pruning | Elimination of unused and unnecessary synapses. |
| Plasticity | Capacity of brain to be modified by experience. |
| Mylin | Fatty tissues that encases cell axon. |
| Cerebellum | `Associated balance and controlls body's movement. |
| Multiple Sclorosis | Autoimmune system strips neurons of mylin leading to loss of motor control. |
| Micro Electrode Recording | Used to measure activity of individual cells. |
| Electroencephalographic Recordings | Measurement acquired with sensors at scalp that show electrical activity of masses of individual cells |
| Event Related Potentials | Specific patterns of brain activity evoked by a specific stimulus. |
| Experience Expectant Processes | Prewired processes. |
| Experience Dependent Processes | Active formation of new synaptic connections in response to the individuals unique experience. |
| Modifiability | Although cells are predestined for specific functions, they can be changed. |
| Sensative Periods | Times in development when organism is especially open to environmental influence. |
| Compensation | Cells substitute for others permitting recovery of a function after loss or damage. |
| Stem Cells | Newest, younges, and least developed cells. Can be grafted to repair damaged parts of the CNS or replace cells that have died. |
| Autonomic Nervous System | Regulates body activities without voluntary control, breathing, blood flow, or digestion. |
| Reflexes | Involuntary responses to certain stimuli that have or had adaptive significance. |
| Cepholocaudal | Head to tail |
| Proximodistal | Center outward |
| Cycle | Moving in an identifiable and predictable rhythm |
