Brain Fucntions Second Test Flashcards
Frontal lobe
Higher mental functions, planning, speech, personality, movement
Longitudinal fissure
Separates two hemispheres of brain
Prefectural gyrus
Controls voluntary movements of skeletal muscles
Central sulcus
Separates frontal and parietal lobes
Postcentral gyrus
Main sensory receptive area for sense of touch
Contains sensory homunculus
Parietal lobe
Spatial awareness, touch, sensation, how pathway
Gyri
Crests
Bumps on surface of brain, help increase amount of cerebral cortex that can fit in skull
Occipital lobe
Vision/visual information
Sulci
Grooves/folds
Depressions/grooves in cerebral cortex, surround gyri, create folds
Optic chiasma
Where the two optic nerves cross
Mammillary body
Forming and recalling memories
Recollective and spatial memory
Hypothalamus
Four f words:
Fornication, fight, flight, feeding
Basic drives
Hormones and metabolism, reproduction
Thalamus
Regulates consciousness, sleep, and alertness
Relays information between sensory organs and cerebral cortex
Corpus callosum
Connects left and right hemispheres of brain
Pineal gland
Produces melatonin
Manages circadian rhythm
Helps maintain rhythm and regulate reproductive hormones
Superior colliculus
Visual reflex
Old pathway
Visual orienting, visual reflexes
Inferior colliculus
Auditory reflex
Receives input from auditory pathway and auditory cortex
Cerebellum
Skilled movements, balance, posture
Medulla oblongata
Regulates necessary bodily functions
Centre for respiration and circulation
Pons
Relay center, sleep, breathing, dreaming
Sleep and dreams, messages to and from the cortex and cerebellum
Cingulate gyrus
Regulates emotions and pain, predicting and avoiding negative consequences
Functions in emotion and behavior
Hippocampus
Learning and memory, especially long term memory and forming new declarative memories
Amygdala
Fear and aggression, emotional control
Olfactory bulb
Processes information about odors
Motor association area
Coordination of complex movement
Primary motor cortex
Determines which body part to move
One of principle brain areas involved in motor function, generates neural impulses that control execution of movement
Primary somatosensory cortex
Receives sensory info
Receives all sensory input from body, especially touch sensors
Wernicke’s area
Syntax of speech, making sentences
Important for language development and comprehension of speech
Visual area
Sight
Auditory cortex
Hearing
Processes auditory information
Motor speech
Formation of words
Functions linked to speech production
