C. 8 Telencephalon Flashcards
Frontal lobe
Precentral gyrus
Somatic motor control
Cerebral cortex (5 lobes)
Frontal Parietal Temporal Occipital Insula
Parietal lobe
Postcentral gyrus Somatesthetic sensation (skin, muscle, tendons, and joints) gustatory
Temporal lobe
Auditory sensation
Interpretation and association of auditory and visual info stored in memory
Occipital lobe
Visual sensation
Coordination of eye movements
Insula lobe
Under temporal lobe
Integrating of sensory (olfactory, gustatory, auditory, and pain) with visceral responses
Memory
Cardiovascular responses to stress
Basal (cerebral) nuclei
- Masses if grey matter deep in the white matter deep to the cortex
- control of learned voluntary movement and postural muscles
- caudate nucleus- degeneration causes Parkinson’s disease
Decussation (crossing over) of fibers
- Each cerebral hemisphere controls movements of the contralateral side of the body.
- each hemisphere receives information from both sides is the body because they communication via the corpus callosum
Cerebral lateralization
Left hemisphere: language and analytical ability
Right hemisphere: visuospatial ability (recognition, comprehension of patterns, part-whole relationship)
Language
Aphasias
Broca’s area
Wernicke’s area
Broca’s area
- Left frontal lobe
- sentence formation and articulation
Wernicke’s area
- left temporal lobe
- language comprehension
- damage produces word salad
Emotion and motivation
- hypothalamus
- lambic system
Limbic system
A.Components of cerebral cortex, cerebral nuclei, and fiber tracts Cingulate gyrus Hippocampus Amygdaloid B. Forms a ring of connections around the brain stem C. Involved in the processing of the olfactory info D. Center of emotion Aggression Fear Feeding and satiety Sex Goal directed behavior E. Forms a circuit with the hypothalamus
