What are the two divisions of the nervous system, and what are their functions? Correct Answer-afferent division (sensory) and efferent division (movement) What are the components of the afferent division of the NS? Correct Answer-Made up of the somatic and visceral sensory pathways. What are the components of the efferent division of the NS? Correct Answer-Made up of the somatic motor pathways that control visceral effectors (ex. skeletal muscles) What do motor pathways provide? Correc...

Accesories of the Afferent Division of the Nervous system Correct Answer-1. Receptors - detects stimuli 2. Sensory neurons - relays sensory information towards the CNS *receives input from dendrites, uses axon to send it to CNS* 3. Sensory pathways - nerves, nuclei, and tracts that deliver sensory information to the CNS Accesories of the Efferent Division of the Nervous system Correct Answer-1. Nuclei - contain cell bodies of motor neurons 2. Motor neurons - send commands to effect...

NURS 660 Exam 1 Study Guide 2023. Pathways in schizophrenia  Brain imaging shows cerebral atrophy and enlarged fluid filled ventricles, as well as shrinkage in prefrontal cortex, temporal, basal ganglia, and limbic regions like hippocampus.  Five dopamine pathways in the brain. The neuroanatomy of dopamine neuronal pathways in the brain can explain the symptoms of schizophrenia as well as the therapeutic effects and side effects of antipsychotic drugs. Know different pathways in th...

mesocortical pathway – executive function: attention, focus, depression nigrostriatal pathway – from substantia nigra (brainstem) to striatum (muscles): Parkinson's mesolimbic pathway – projects to nucleus accumbens (part of limbic system). Pleasure, reward, positive symptoms of schizophrenia: Addiction, gambling Tuberoinfundibular pathway – regulation of prolactin (acts on pituitary). Hypersexuality in mania Dopamine – produced in substania nigra and VTA. D2 & D4 receptors ...
