NSCI 1001 Exam 1 UMN
Brain Functions, Structures, Anatomy, Vestibular
Question | Answer |
---|---|
Collection of Neurons | Nucleus |
Collection of Nuclei | Region |
Layers of the Meninges (from outermost to innermost) | Dura Mater (2 layers), Arachnoid, Pia Mater |
Functions of the Ventricles | Cerebrospinal Fluid (CSF) Production, Bouyancy/Protection, Removal of Waste |
Main Structures of the Forebrain | Olfactory Bulb, Cerebrum, Thalamus, Hypothalamus |
Lobes of the Cortex | Frontal, Parietal, Temporal, Occipital, |
Frontal Lobe Function | Movement, Judgment, Impulse Control |
Parietal Lobe Function | Sensory Processing, Movement |
Temporal Lobe Function | Hearing, Language, Emotion |
Occipital Lobe | Vision |
Location of Striatum | Under the Cortex |
Structures of the Striatum | Caudate and Nucleus Accumbens |
Caudate Function/Disorder | Function: Sensory/Motor Function, Disorder: Schizophrenia, Obsessive Compulsive Disorder |
Nucleus Accumbens Function/Disorder | Function: Reward/Motivation, Disorder: Addictions |
Hippocampus Function | Learning Location in Space (Spatial Learning), Stress Regulation |
Thalamus Function | Relay information to cortex |
Hypothalamus Function | Sex, Eating, Stress |
Main Structures of Midbrain | Substantia Nigra, Inferior/Superior Colliculus, Ventral Tegmentum, Central Gray |
Substantia Nigra Function/Disorder | Function: Movement, Disorder: Parkinsons causes death of region |
Inferior Colliculus (IS) | Hearing |
Superior Colliculus (SC) | Vision |
Central Gray | Pain |
Ventral Tegmentum | Reward/Motivation |
Main structures of Hindbrain | Cerebellum, Pons/Medulla |
Cerebellum Function | Fine Movements, Posture, Balance |
Pons and Medulla Function | Sleep/Wakefulness, Breathing, Blood Pressure, Digestion, Autonomic Functions |
Structures involved in Reward/Motivation | Ventral Tegmentum and Nucleus Accumbens |
Steps in Synaptic Transmission | 1) Synthesis of Neurotransmitters, 2) Storage (in vesicles), 3) Release into synapse (activated by action potential), 4) Receptor Activation, 5) Inactivation |
Dominant form of neurotransmitter inactivation | Reuptake |
Dopamine Synthesis Pathway | L-DOPA --> Dopamine |
Dopamine disorders | Deficiency: Parkinsons, Excess: Schizophrenia |
Dopamine Reuptake Inhibitor | Amphetamine (Used to treat ADD) |
Dopamine Receptors and Function | D1) Stimulate post-synaptic neurons, D2) Inhibit post-synaptic neurons |
Commonly prescribed antibiotic that caused destruction of vestibular system in case study | Gentamicin |
Rotation around each axis of balance (All 3) | X-Axis (Pointing straight out from nose): Roll, Y-Axis (Ear to ear) - Pitch, Z-Axis (Top to bottom of head) - Yaw |
Contribution of Camillo Golgi | Developed Silver Stain (Stains 1 in 1000 Neurons) |
Contribution of Santiago Ramon y Caja | Utilized Golgi's Silver Stain to map nervous system |
Contribution of Paul Broca | Discovered region responsible for SPEECH PRODUCTION |
Contribution of Carl Wernicke | Discovered region responsible for SPEECH RECOGNITION |
Broca's Aphasia | Understanding is unphased Limited vocabulary |
Wernicke's Aphasia | Cannot understand spoken words Speech output is unphased |
