1 what is it? nervous system composition: 2 cell types neurons glia

2 parts of neuron - function - structure

3 neural communication electrical within, chemical between

4 vesicles, exocytosis, & binding

5 epinephrine (E) & norepinephrine (NE) neurotransmitters glutamate (+) vs GABA (-) acetylcholine (Ach) dopamine (DA) serotonin (5-HT) about receptor subtypes…

6 inactivating NTs reuptake enzymatic breakdown diffusion

7 effects after binding IONOTROPIC METABOTROPIC - cascade of events requiring energy - turn on/off genes - alters structure of the cell - fast

8 nervous system central nervous system peripheral nervous system brain spinal cord somatic NS autonomicNS sensory nerves motor nerves sympathetic NS parasympathetic NS

9 cortex brain stem subcortical structures brain anatomy

10 forebrain, midbrain, hindbrain during neurodevelopment when fully developed

11 subdivisions of brain

12 ventricles central canalventricles

13 cerebrospinal fluid choroid plexus

14 hindbrain medulla RAS & raphe vital functions reflexes

15 hindbrain pons RAS & raphe REM & paralysis decussation locus coeruleus

16 hindbrain cerebellum coordination Integrates intention for movement w/ balance, motor, senses learning

17 hindbrain & midbrain

18 midbrain tegmentum

19 forebrain’s diencephalon

20 forebrain’s telencephalon limbic system Amygdala Hippocampus Cingulate gyrus Hypothalamus?

21 forebrain’s telencephalon basal ganglia

22 cortical lobes

23

24 executive functions planning & organizing working memory (internally-guided) sequencing set-shifting vs perseveration abstract thinking inhibition maturation of PFC cells
