Intro to the nervous system
What is the central nervous system composed of?
What is the brain and spinal cord
What is several sub-threshold impulses combined to each threshold?
What is summation?
What is the function of neurons?
What is conducting impulses?
What is the strongest layer of the brain, made out of dense connective tissue?
What is dura matter?
What is bone, meninges, and cerebrospinal fluid?
What are the three general functions of the Nervous System?
What is sensory, integration, and motor ability?
What are chemicals that allow neurons to communicate?
What are the gaps in the myelin sheath?
What are Nodes of Ranvier?
What does Cerebrospinal Fluid provide to the brain?
What are nutrients?
Where does the spinal cord begin?
What is the base of the brain?
What is "fight or flight?"
What is the "All or None" response?
What is: if a neuron respons at all, it responds completely; greater intensity of stimulation triggers more impulses per second, not stronger impulses
What phagocytizes bacterial cells and dead neurons?
What is Microglia?
What lobe of the cerebrum senses taste?
What is the Insula?
What is the core of gray matter composed of?
What are interneurons and cell bodies?
What is the physical response of the parasympathetic nervous system?
How is nerve stimulation ended (there are two methods)?
What is removal and decomposition?
What neuron is numerous and receives stimuli?
What are dendrites?
When does the prefrontal cortex finish developing?
What are mid-20s?
What is an automatic, involuntary response to stimuli?
What is a reflex arc?
What is the peripheral nervous system composed of?
What are nerves that extend from the brain and spinal cord?
What type of potential occurs when Na+ channels open, Na+ ions rush into the cell?
What is action potential?
What type of neuron is found primarily in CNS and links sensory and motor neurons?
What are interneurons?
Where is the primary sensory cortex located
What is the anterior portion of the parietal lobe and behind the central sulcus?
What is a stretch reflex?
