Problems with semantics
What is Broca's aphasia?
Problems with syntax
What is the function of the hypothalamus?
Regulates body function, homeostatic control and integration center
What are the functions of the medulla?
Relay station between the spinal cord and brain; controls reflex activities (coughing, gagging, swallowing, vomiting)
What are the functions of the pons?
Relays info between the cerebellum and cerebral cortex; relays info from the medulla to higher cortical regions; involved in breathing, sleeping, and several sense
What does the medulla contain?
Respiratory, cardiac, and vasomotor control centers
What is the limbic system?
Ring of forebrain structures involved in basic survival instincts, motivation, emotions, learning and memory
What is the function of the thalamus?
Sensory gateway
What does the parietal lobe control?
Somatosensation; pain, temperature, touch, and proprioception
What does the basal nuclei in the brain contain?
Subcortical collections of gray matter; aka basal ganglia
Cerebrospinal fluid (CSF) is located in the subarachnoid space of the brain, T/F?
T
Parietal and temporal go from 1 to 2 to 3, T or F?
T
Regarding motivation, homeostatic drives satisfy bodily needs (thirst, hunger), T/F?
T
T/F: L side of the brain is good at math/sciences while the R side of the brain is more creative with arts/writing
T
T/F: Melatonin is found in the pineal gland
T
T/F: Melatonin secretion is influenced by light and dark
T
T/F: The cerebellum is to the right of the brainstem (if looking at the brain from the side)
T
T/F: The cerebral cortex can modify, reinforce, or repress our basic survival instincts (fleeing, mating, hunting)
T
T/F: The cerebral cortex is important for conscious awareness of feelings
T
T/F: The corpus callosum lies between the cerebrum and diencephalon
T
T/F: The midbrain as a superior and inferior colliculus
