Parts Of The Brain Flashcards
(15 cards)
Cortex
Localizes and interprets sensory inputs
Controls voluntary and skilled muscle activity
Acts in intellectual and emotional processing
Basal nuclei(ganglia)
Subcortical motor centers
Help control muscle movements
Thalamus
Relays sensory impulses to cerebral cortex
Relays impulses between cerebral motor cortex and lower motor centers
Involved in memory
Hypothalamus
Cheif integration center of autonomic nervous system
Regulates body temp, food intake, water balance and thirst
Regulates hormonal output of pituitary gland
Acts as an endocrine organ
Produces ADH
Produces oxytocin
Limbic system
Includes cerebral and diencephalon
Mediates emotional response
Involved in memory processing
Midbrain
Contains visual and auditory reflex centers
Contains subcortical motor centers
Contains nuclei for cranial nerves III and IV
Contain projection fibers
Pons
Relays info from the cerebellum to the cerebrum
Cooperates with the medullary centers to control respiratory rate and depth
Contains nuclei for cranial nerves V-VII
Contains projection fibers
Site of decussation of pyramids
Reticular formation
Maintains cerebral cortical alertness
Filters out repetitive stimuli
Helps regulate skeletal and visceral muscle activity
Cerebellum
Processes information from cerebral motor cortex, proprioceptors and visual and equilibrium pathways
Provides instructions to cerebral motor cortex and subcortical motor centers
Facilitates coordinated skeletal muscle movements
Responsible for proper balance and posture
Frontal lobe
Anterior association area
Working memory and judgment
Problem solving
Language comprehension
Precentral gyrus
Premotor area
Postcentral gyrus
Primary somatic sensory area
Motor speech
Taste
Temporal lobe
Olfactory area
Auditory area
Visual area
Speech and language
Parietal lobe
Speech and language
Occipital lobe
Visual area
