Physiology (Brain anatomy and physiology) Flashcards
The hindbrain consists of the pons, the medulla, and the cerebellum. The ________ regulates a number of vital functions and damage to this structure is often fatal
medulla
The ______ is important for balance, posture, and coordination, and damage can produce _____, which involves slurred speech, severe tremors, and a loss of balance
cerebellum; ataxia
The midbrain includes the _____, which is vital to consciousness, arousal, and wakefulness
reticular activating system (RAS)
The forebrain consists of subcortical structures. One of the subcortical structures, the ______, acts as a relay station for all the senses except ______
thalamus; olfaction
_____ syndrome is due to a thiamine deficiency that causes atrophy of neurons in certain areas of the thalamus and the mammillary bodies of the hypothalamus and is usually the result of chronic alcoholism
Wernicke-Korsakoff
The ______ governs a number of vital functions (e.g., hunger, thirst, temperature), integrates and coordinates emotional reactions, and initiates the responses needed to maintain the body’s internal ________
hypothalamus; homeostasis
The ______ mediates the sleep-wake cycle and other circadian rhythms
SCN (suprachiasmatic nucleus)
The ______ are important in planning, organizing, and coordinating voluntary movements.
basal ganglia
The basil ganglia are involved in several disorders with prominent motor symptoms including Huntington’s disease, _______ disease, Tourette’s disorder, and ADHD
Parkinson’s
The limbic system is associated primarily with emotional activities. The amygdala attaches emotions to ______,, and damage to the amygdala and temporal lobes can produce _____ syndrome, which is characterized by reduced fear and aggression, psychic blindness, and hypersexuality
memories; Kluver-Bucy
The hippocampus is involved more with learning and memory than with emotions and is responsible for ______ declarative memories
consolidating
The right and left hemispheres of the cerebral cortex are connected by several bundles of fibres, the largest is the ________
corpus callosum
For most sensory and motor functions, the cerebral cortex exhibits ______ representation, which means that the left side of the brain controls the right side of the body and vice versa
contralateral
While both hemispheres play a role in most behaviours, the ______ (usually left) hemisphere is primarily responsible for language, ______ memory, and ______ emotions, while the ____ (usually right) hemisphere governs _____ recognition, nonverbal memory, and _____ emotions
dominant; verbal; positive; non-dominant; facial; negative
Brain lateralization has been demonstrated by studies examining the effects of severing the corpus callosum in order to control severe _______
epilepsy
