Brain structures
Question | Answer |
---|---|
Hindbrain | in top part of the spinal cord medulla pons and cerebellum life support system controls basic biological functions |
Medulla | controls blood pressure, heart rate, and breathing can be medulla oblongata |
Pons | connects hindbrain with mid and forebrain controls facial expressions |
Cerebellum | called little brain coordinated habitual movements |
Midbrain | just above spinal cord controls simple movements between hind and forebrain integrates some sensory info and muscle movements reticula formation controls body's arousal and ability to focus coma if not functioning |
Forebrain | control thought and reason thalamus, hypothalamus, amygdale, and hippocampus |
Thalamus | top of the brain stem receives sensory signals, sends them to the right areas in the rest of the forebrain. |
Hypothalamus | next to the thalamus control metabolic functions such as body temperature,sexual arousal, hunger, thirst, and the endocrine system |
Amygdala | vital to emotional experiences |
Hippocampus | vital to memory system memories are processed, not stored, here |
Cerebral cortex | is wrinkled to increase surface area. |
Hemispheres | left and right control sensory messages and motor functions from the OPPOSITE side of the body |
Frontal lobes | front of the skull behind the eyes |
Prefrontal cortex | thought processes foreseeing consequences, pursuing goals, maintaining emotional control |
Broca's area | controls muscles for producing speech |
Parietal | contains sensory cortex receives incoming touch sensations |
Occipital lobe | interprets messages from our eyes in our visual cortex |
Temporal lobes | processes sound Wernicke's area - interprets both written and spoken speech |
Brain plasticity | brain is damaged then dendrites can make new connections |
