Question | Answer |
The principal effector elements of the limbic system are ? | * hypothalamus and the reticular formation |
Basic action of the Limbic System ? | *Provides emotions…..all sensory info filters in to limbic system and translates it to what we do autonomically |
Limbic functions ? | *HOME ---homeostasis, olfactory, memory, emotion |
Limbic inputs project to ? | * hypothalamus |
The informational flow into the hippocampal formation permits ? | * provides a link to past experiences (memory) |
Entry of information into the limbic system is either ? | * directly to the amygdala (fear), or indirectly to the hippocampal formation (memory), via the entorhinal area |
Limbic Structures that give rise to the the 4 main functions ? | *Homeostasis - hypothalamus *Olfactory - olfactory cortex *Memory - hippocampus *Emotions -amygdala |
The Limbic Cortex or Lobe forms a ring around ? | * callosum callosum and upper brainstem-diencephalic junction |
The Limbic lobe includes ? | *subcallosal area *cingulate gyrus and isthmus of the cingulated gyrus *parahippocampal gyrus *the uncus *The temporal pole *Orbital frontal gyri |
The hippocampus lines ? | * the lateral ventricle |
Limbic System Components ? | * Amygdala *Mammillary body -Anterior nucleus -Mediodorsal nucleus *Nucleus accumbens *Basal forebrain *Septal nuclei |
Produce ACh ? | *basal forebrain and septal nuclei |
The Papez Circuit ? | *hippocompal fibers --> fornix --> mammillary body --> mammillio-thalamic tract -->anterior thalamic nucleus --> cingulate gyrus --> hippocampus |
major output from hippocampal formation ? | * fornix |
limbic lobe info to hippocampal formation ? | * Cingulum |
The olfactory system is remarkable in four respects ? | *primary afferents occupy the surface epi, *The axons of the primary afferents enter the cerebral cortex directly, *primary afferent neurons undergo turnover, being replaced from basal stem cells, *The pathway to the cortical centers are ipsilateral |
The collective processes of these neurons form the olfactory nerve? | *Olfactory bipolar neurons |
supporting cells- maintain neurons ? | *Sustentacular cells |
maintain a continuous population of olfactory neurons – make new neurons ? | *basal cells |
The lateral olfactory stria terminates in ? | * the primary olfactory cortex |
links the olfactory cortical areas with the hypothalamus and brainstem ? | * The medial forebrain bundle -----* olfactory comples-->medial bundle-->hypothalamus/brainstem.....these trigger ANS responses such as salivation, and gastric contractions |
