A network of neurons involved in regulating attention, alertness, and arousal: reticular formation

A set of structures in the brain especially involved in the experience of emotion: Limbic system

lobes at the back of the head that process visual stimuli: occipital lobes

part of the hindbrain involved in regulating vital life functions: medulla

lobes at the top and front of the brain, most involved in higher-order functions: frontal lobes

portion of the forebrain divided into two hemispheres: cerebrum

part of the limbic system most involved in the formation of memories: hippocampus

brain structure in the limbic system involved in many functions, including sexual reproduction, emotional reactions, and maintaining internal body temperature: hypothalamus

lobes located in the upper back of the head; process information relation to touch, pressure, external temperature: parietal lobes

one component of the limbic system; particularly involved in the experiences of fear, agression: amygdala

lobes located on the sides of the head near the ear; primary function involves processing speech/sound: temporal lobes

outer covering of the cerebrum: cerebral cortex

brain structure located in the back of the head; vital for balance and coordination: cerebellum

the part of the brain that joins the cerebral hemispheres: corpus callosum

the amygdala, hippocampus, and parts of the thalamus and hypothalamus make up the...: limbic system

which lobe of the brain is responsbile for hearing: temporal

what makes up 80% of the brain's total mass?: cerebral cortex

brain chemicals that moderate pain messages and produce feelings of pleasure: endorphins

nerve cells: neurons

fibers extending out from the soma of the neuron; receive incoming messages from adjoining neurons: dendrite

neurons in the peripheral nervous system that transport messages from spinal cord to muscles and glands: motor neurons

connection between neurons where neural message becomes chemical (carried by neurotransmitters): synapse

chemicals present in the brain that allow for message transmissions among nerve cells: neurotransmitters

The part of the neuron conducting messages down the length of the cell toward connections with other neurons; usually the longest part of a neuron: axon

a fatty protective layer that covers the axons of some nerve cells and helps speed transmission of neural impulses: myelin sheath

neurons that receive messages from sensory receptors and transmit that information to the spinal cord: sensory neurons

locations on neurons receiving incoming messages; neurotransmitters fit into these sites: receptor site

the part of the neuron that receives incoming messages is the...: dendrites

axons are often covered with a layer called the ___ that contain(s) the nodes of ranvier: myelin sheath

transmission of a neural impulse travels from ___ at the receiving end of the cell to ___ at the other end of the cell: dendrites; terminal buttons

neural messages become chemical in nature and are transmitted by neurotransmitters across the...: synapse

___ carry messages away from the spinal cord and brain: motor neurons

adopted by Wundt, analysis of the basic elements that constitute the mind: Structuralism

functionalism: developed by William James, study of the purpose mental processes serve in enabling people to adapt to their enviroment

hindbrain: area of the brain that coordinates info in and out of the spinal cord

medulla: extension of the spinal cord into the skull that coordinates heart rate, circulation, and respiration]

Cerebellum: structure of hindbrain that controls fine motor skills

pons: brain structure that relays information from the cerebellum to the rest of the brain

subcortical structure that transmits information to: Thalamus

Occipital Lobe: region of cerebral cortex that processes visual information

parietal lobe: region of cerebral cortex processes information about touch

region of cerebral cortex responsible for hearing: Temporal Lobe

frontal lobe: region of cerebral cortex that has specialized areas for movement, abstract thinking, planning, memory and judgement

hippocampus: structure critical for creating new memories

area of neurons running down the front of the parietal lobes responsible for processing information from the skin and internal body receptors for touch, temperature, body position, and possibly taste: Somatosensory cortex

highest level of the brain, critical for complex cognitive, emotional, sensory and motor functions, contains the cerebral cortex and its subcortical structures: forebrain

coordinates information coming out of the spinal cord and controls the basic functions of life, contains the medulla, reticular formation, the cerebellum, and the pons: hindbrain

Peripheral NS?: sensory systems and skeletal motor systems

Autonomic NS?: parasympathetic NS and sympathetic NS

action potential: exitation traveling across an axon at a constant strength, no matter the distance.

resting potential: an electrical polarization across the membrane of an axon.

presynaptic neuron: message sending

postsynaptic neuron: message recieving

graded potentials: ripples in pond; electrochemical changes are greatest near synapses. get weaker the farther away.
