11 Cards in this Set

  • Front
  • Back

medulla

- where most fibers cross resulting in contralateral control (control of one side of the body by the other side of the brain)



- regulates heart rhythm, blood flow, digestion, and vomiting



pons

- contains part of the reticular activating system (reticular formation) that controls arousal



- bridge between cerebral hemispheres and medulla and cerebellum

cerebellum

- coordinates motor function, integrating motion, and positional information from inner ear and muscles



- helps maintain balance

basil ganglia/basal nuclei

- links thalamus with motor cortex and surrounding areas



- regulates initiation of movement, balance, eye movements, and posture



- involved in reward/punishment learning, focus, and functions in processing of implicit memory



- some neural clusters/nuclei involved in emotions



(Provide both names, “i” before “a”)

thalamus

- relay station for sensory pathways carrying visual, auditory, taste, somatosensory information to and/or from the corresponding areas of the cerebral cortex



- some neural clusters/nuclei involved in emotions

hypothalamus

- controls autonomic functions (body temperature, heart rate, etc) through control of sympathetic and parasympathetic centers in the medulla



- sets appetite drives (hunger, thirst, sexual desire) and corresponding behaviors



- works with limbic system in order to set emotional state such as rage



- works with endocrine system by secreting hormones that regulate pituitary hormones



- helps determine biological rhythms such as the menstrual cycle

amygdala

- influences aggression and fear



- coordinates fight or flight response



- important in formation of sensory memory

hippocampus

- enables formation of long-term memory

cerebrum/cerebral cortex

- receives and processed sensory information



- directs movement



- center for higher order processes (thinking, planning, judgment)


associated areas

- subdivision of cerebral cortex



- regions of cerebral cortex with no specific sensory or motor functions



- involved in higher mental functions (thinking, planning, remembering, and communicating)

plasticity

If one part of the brain is damaged, the brain can reorganize and take over the damaged region’s function. This concept is called __________.
