cerebral lobes

The flashcards below were created by user asharp on FreezingBlue Flashcards.

  1. -most anterior lobe of the brain
    -boundaries are the central sulcus, which separates it from the parietal lobe, and the lateral fissure, which separates it from the temporal lobe
    -functions are:
        -emotional response
        -planning and executive of complex actions
        -control of voluntary muscle movement
    frontal lobe
  2. -the frontal lobe is also involved in speech production and contains the motor speech (language) center ...
    -lies unilaterally on the inferior surface of the frontal lobe dominant for language, typically in the left frontal gyrus
    -this area is involved in the coordination or programming of motor movements for the production of speech sounds
    Broca's area
  3. -located in the middle portion of each cerebral hemisphere just posterior to the central sulcus
    -horizontal portion of the lateral fissure separates this from the temporal lobe
    -associated with the perception of temperature, touch, pressure, vibration, pain, taste and is involved in writing and in some aspects of reading
    parietal lobe
  4. -most posterior lobe
    -separated from the parietal lobe by the parietooccipital fissure
    -involved in the conscious perception of visual stimuli
    occipital lobe
  5. receives input from the optic tract via the optic radiations extending from the thalamus
    primary visual area
  6. -anterior to the occipital lobe and is separated from the parietal lobe by the lateral fissure
    - functions are conscious perceptions of auditory and olfactory stimuli and dominance for language
    temporal lobe
  7. memory processing occurs via the amygdala and hippocampus, clusters of gray matter located in the ... of the temporal lobe
    parahippocampal gyrus
  8. located on the ... is the auditory cortex, which can be divided into primary and secondary auditory areas
    superior temporal gyrus
  9. the primary auditory area ... receives the major auditory sensory information from the bilateral cochlea
    Heschl's gyrus
  10. the secondary auditory area ... is the center for comprehension and formulation of speech
    Wernicke's area
  11. -deep in the temporal lobe is another area of cortical gray matter termed the ... often referred to as the fifth lobe
    -separated from the temporal lobe by the lateral fissure and viscera
    insula (island of Reil)
  12. -collection of subcortical gray matter consisting of the caudate nucleaus, lentiform nucleus, and claistrum
    -collectively they contribute to the planning and programming of muscle action and movement
    -largest are the caudate nucleus and lentiform nucleus
    -both nuclei serve as relay stations between the thalamus and the cerebral cortex of the same side
    basal nuclei (ganglia)
  13. parallels the lateral ventricle and consists of a head, body, and tail
    caudate nucleus
  14. causes an indentation to the frontal horns of the lateral ventricle
    head of basal ganglia
  15. terminates at the amygdala in the temporal lobe lobe
    tail of basal ganglia
  16. -biconvex lens-shaped mass of gray matter located among the insula, caudate nucleus, and thalamus
    -further divides into the GLOBUS PALLIDUS and the PUTAMEN
    lentiform nucleus
  17. thin linear layer of gray matter lying between the insula and the lentiform nucleus and is thought to be involved with the mediation of the visual attention
  18. -shaped like a boomerand
    -separates the thalamus and caudate nucleus from the lentiform nucleus
    internal capsule
  19. thin layer of white matter that separates the claustrum from the lentiform nucleus
    external capsule
  20. thin layer of white matter located between the claustrum and insular cortex
    extreme capsule
