CNS has two components | spinal cord and brain |
brain is composed of | forebrain, midbrain, hindbrain |
PNS has two main components | somatic and autonomic nervous system |
somatic nervous system is composed of | afferent neurons and efferent neurons |
autonomic nervous system is composed of | parasympathetic and sympathetic nervous systems |
region associated with higher thinking | forebrain |
associated with directing movement, sensory integration, language learning and memory | cerebrum |
portion of the brain associated with emotion and memory formation | limbic system |
integration center; plays an important role in coordinating the senses, consciousness, alertness and sleep | thalamus |
connects the nervous system and endocrine system. It is associated with thermoregulation, hunger, thirst, hydration, sleep, and circadian rhythms | hypothalamus |
helps integrate information from various parts of the brain. In this way it plays a role in motor coordination and motivation | midbrain |
associated with the more critical functions of life. constructed of anatomical structures found in the most inferior aspect of the brain. | hindbrain |
neurotransmitter CNS: associated with areas of the brain involved in directing and coordinating movement PNS: stimulates contraction of muscles at the neuromuscular junction | acetylcholine |
neurotransmitter CNS: primarily used by the brain stem PNS: primary neurotransmitter used by the sympathetic nervous system | norepinephrine |
neurotransmitter CNS: primarily found in brain stem. Associated with motivation and movemant PNS small role related to digestion | dopamine |
neurotransmitter CNS: found throughout the brain. Usually an inhibitory neurotransmitter. PNS: no role | GABA |
neurotransmitter CNS: found throughout the brain. Associated with consciousness and perception PNS: no role | serotonin |
neurotransmitter CNS: found throughout the brain. Usually an excitatory neurotransmitter. Associated with learning and memory formation PNS: no role | glutamate |
