Anatomy Exam 4


telencephalon structures cerebrum, cerebral cortex, caudate, putamin, globus pallidus, limbic system
diencephalon structures thalamus, hypothalamus, epithalamus, subthalamus
mesencephalon structures brainstem, midbrain
metencephaolon structures pons, cerebellum
myelincephalon structures medulla oblongata
neural crest structures sensory ganglia, autonomic ganglia, schwann cells, adrenal medulla, digestive neuron, arachnid and piacovering
amygdala involved in emotion, especially fear
basal ganglia a group of telencephalonic nuclei that fine tune motor activity; caudate putamen, globulus pallidus
cerebrum controls higher mental function
corpus collosum white matter tract that connects two cerebral cortical hemispheres
epithalamus regulates daily rhythms
hippocampus involved in learning and memory
hypothalamus regulates autonomic homeostasis
inferior colliculus plays a role in sound localiation and associated reflexs
internal capsule white matter tract that connects the cerebral cortex with other brain parts
medulla oblongata vital to life: regulates breathing, heartbeat, blood pressure
midbrain maintains consciousness
nucleus accumbens involved in reward/addiction
pons controls face sensory and motor functions, horizontal eye movement
subthalamic nucleus diancephalic basal ganglia nucleus
superior colliculus controls eye movement and pupil constriction
thalamus functions as a sensory relay
cerebellum hind brain structure that coordinates body movements
excitatory neurotransmitters glutamate, aspartate
inhibitory neurotransmitters GABA, glycine
peptide neurotransmitters Substance P, enkephalin, endorphin
catecholamine neurotransmitters dopamine, norepinephrin, epinephrine
neurotransmitter made by motor neurons acetylcholine
neurotransmitter made by brainstem by locus coeruleus norepinephrine
neurotransmitter made in brainstem by raphe nucleus serotonin
neurotransmitter made in brainstem by substantia naigra dopamine
increased release of neurotransmitter induces epilepsy glutamate, aspartate
transmits pain sensation to periphery substance p
increased activity results in schizophrenia dopamine
increased activity results in mania norepinephrine
PCP binds to receptor glutamate
valium and barbituates bind with receptor GABA
cocaine effects neurotransmitter dopamine
LSD and Ecstacy activate receptor serotonin
receptor is a Ca channel glutamate
neurotransmitter degraded in synaptic cleft acetylcholine
amphetamines increases release dopamine
ALS/ Lou Gherigs disease death of motor neurons due to gultamate neurotoxicity
myasthenia gravis autoimmune destruction of acetylcholine receptors
anacephaly high glucose levels resulting in rostral neural tube closure failure
alzheimers death of nucleus basalis of meynert neurons that make acetylcholine
parkinsons disease death of substantia naigra neurons that make dopamine
spina bifida folic acid deficiency results in caudal neural tube closure failure
