Quiz 2 Flashcards
Medulla Oblongata
controls involuntary functions (breathing, blood pressure, swallowing)
Transfers neural messages from brain to spinal cord
Pons
bridge between upper and lower part of brain
- sleep and arousal
- unconscious movements
Reticular formation
- control sleep, arousal, attention
- active in motion
- SENSORY FILTER
Cerebellum (little brain)
- controls balance and coordinates complex voluntary movements
- ouput, excitatory
Basal Ganglia
helps to coordinate deliberate movements
- keep out unwanted movements (inhibitory)
Thalamus
- takes messages to and from cerebral cortex from all sense organs except nose
Amygdala
reponsible for response/memory of emotion, espeically fear
controls autonomic responses of fear
Hippocampus
formation of long term episodic memories
spatial navigatio
Hypothalamus
- fleeing
- fighting
- feeding
- fornicating
Olfactory Bulb
involved in perception of odors
smells evoke strong memories
Frontal lobe (motor cortex)
- body movement
- personality
- speech
- judgement
- impulse control
parietal lobe (somatosensory cortex)
- touch and pressure, taste and body awareness (orientation, vestibular sense)
- process incoming stimulus
occipital lobe (visual cortex)
- primary visual cortex
- visual processing
Temporal Lobe (auditory cortex)
- primary auditory cortex
- primary olfactory cortex (smell)
- contains Wernicke’s Area
- recognizes faces as faces not blob
Association areas
Areas of the cortex NOT involved with motor or sensory functions. Involved with higher mental functions (learning, remembering, thinking, speaker)
Broca’s area (left frontal lobe)
controls language expression; directs muscle movements involved in speech
Wernicke’s Area
- key role in language comprehension, expression
- language reception
Aphasia
impairment of language
caused by left hemisphere damage
