First Theorized that thoughts and ideas come from the brain && while others at the time are thought the heart and stomach | Hippocrates (460-377 B.C.) |
Fluid that cushions the brain | Cerebrospinal Fluid |
Blocks Drugs and Toxins | Blood Brain Barrier |
Central Nervous System Consists of... | Brain and Spinal Cord |
Connects Brain to the rest of the body | Spinal Cord |
Main organ of the nervous system | Brain |
Glial Cells | Structural Support For Neurons. insulate neurons, nourish neurons, remove waste products |
Act as communicators of the nervous system | Neurons |
Cell Body | Soma |
A highly branched fibers that reach out from the neuron which receive information from other neurons or from sense organs | Dendrite |
A single long fiber that extends from the neuron is called | The Axon |
A single long fiber that extends from the neuron is called | The Axon |
Junction Between Axon of one neuron and the cell body or dendrite of a neighboring neuron is known as | Synapse |
Chemicals that can cross over to neighboring neurons and activate them... | Neurotransmitters. |
Positively and Negatively Charged Atoms And Molecules are known as... | Ions |
All Or None Law | Fundamental Law Governing Neural Impulses && stronger impulses send signals at faster rate. |
Short lived charge in electric signal inside the neuron | Action Potential |
Gap Between Two Cells In Synapse | Synaptic Cleft |
Measures electrical activity of the brain | EEG |
Locate cell activity in the brain to record radioactive substances become concentrated when injected into the bloodstream | PET Scan |
An extension of the spinal cord contained inside the skull where nuclei control blood pressure, heart rate, breathing, and other vital functions | Hindbrain |
An are in the hindbrain that controls blood pressure, heart rate, breathing, and other vital functions | Medulla |
A network of cells ad fibers threaded throughout the hindbrain and midbrain that alters the activity of the rest of the brain | Reticular Formation |
The part of the hindbrain whose function is to control finely coordinated movements and to store learned associations that involve movement | Cerebellum |
A small nucleus in the reticular formation involved in attention, sleep, and mood. | Locus Coeruleus |
Midbrain | A small structure between the hidbrain and forebrain that relays information from the eyes, ears, and skin and that controls certain types of automatic behaviors |
Substantia Nigra | An are of the midbrain involved in the smooth initiation of movement |
Striatum | A structure within the forebrain that is involved in the smooth initiation of movement |
Forebrain | The most highly developed part of the brain; it is responsible for the most complex aspects of behavior and mental life |
Thalamus | A forebrain structure that relays signals from most sense organs to higher levels in the brain and plays an important role in the processing and making sense out of the information |
A structure in the forebrain that regulates, thirst, and sex drives | Hypothalamus |
Suprachiasmatic nuclei | Nuclei in the hypothalamus that generate biological rhythm |
Amygdala | A structure in the forebrain that, among other things, associates features of stimuli from sensory modalities |
Hippocampus | A structure in the forebrain associated with the formation of new memories |
Limbic System | A set of brain structures that play important roles in regulating emotion and memory |
Cerebral Hemisphere | The left and right halves of the rounded, outermost part of the brain |
Cerebral cortex | the outer surface of the brain |
Sensory cortex | the parts of the cerebral cortex that receive stimulus information form the senses |
Motor cortex | The part of the cerebral cortex whose neurons control voluntary movements in specific parts of the body |
Association cortex | Those parts of the cerebral cortex that receive information from more than one sense or that combine sensory an motor information to perform complex cognitive tasks |
Corpus Callosum | A massive bundle of fibers that connects the right and left cerebral hemispheres and allows tham to communicate with each other. |
