Brain Flashcards
(30 cards)
Cerebrum
Includes cerebral cortex
Brain consist of 3 parts
Forebrain, cerebellum, and brainstem
Diencephalon
Thalamus and hypothalamus
Cerebellum
Motor coordination
Balance
Smooth movements
Corrections in force and direction in movement when detects discrepancy
Brainstem
Connects forebrain and spinal cord. Includes: midbrain, pons, and medulla oblongata
Brainstem
Many involuntary functions controlled by ANS like cardiovascular function and digestion
Cerebral cortex
Highest level of neural processing. Integrating center
Sulci
Grooves in brain
Gyri
Ridges on brain
Occipital lobe
Visual cortex
Auditory cortex
Hearing
Frontal lobe
Primary motor cortex. Initiates voluntary movement. Language Planning Personality (Phineas Gage story)
Right side of brain
Spatial orientation Creativity Face recognition Music Dream imagery Philosophy Intuition
Left side of brain
Logic Analytical processing Strong language capabilities Math skills Dominant for speech
Thalamus
Relay center
Sensory info except smell
Filters and transmits to cortex
Hypothalamus
Homeostasis
Link between endocrine and nervous system
Controls release of hormones including antidiuretic–regulates plasma volume and osmolarity, and oxytocin–regulates uterine contractions and milk ejection
More hypothalamus
Affects behavior Regulates eating and drinking behavior Thermoregulatory center Part of lambic system--emotions and behaviors in response to emotions Stress
Hypothalamus
Regulates circadian rhythm
Hormone melatonin–plays a role in establishing the circadian rhythm
Limbic system
Autonomic functions Motivation Memory Emotional Hippocampus--learning and memory
Basal nuclei
Provides feedback to cortex to help with smooth movements
Inhibits unwanted movements
Diseases that effect basal nuclei
Parkinson’s
Huntington’s chorea
Wernicke’s area
Language comprehension
Ability to understand language
Broca’s area
Language expression
Our ability to speak or write words
Damage to Wernicke’s causes
Wernicke’s aphasia–difficulty understanding words written or spoken
Can speak but makes no sense
