Primary motor area
What is a relay station for sensory impulses passing upward to the sensory cortex?
What is the primary motor area found in?
What is the blood brain barrier useless against?
Fat-soluble molecules, fats, and respiratory gases
Where do complex memories appear?
Frontal and temporal lobes
What are the major structures of the diencephalon?
Epithalamus, hypothalamus, and thalamus
What provides the precise timing for skeletal muscle activity and controls our balance and equilibrium?
What cannot get through the blood brain barrier?
Metabolic wastes and most drugs
What connects the cerebral hemispheres?
What allows you to recognize pain, coldness, or a light touch?
Primary somatic sensory area
What helps regulate voluntary motor activities by modifying instructions sent to the skeletal muscles by primary motor cortex?
Speech, memory, logical and emotional response, consciousness, interpretation of sensation, and voluntary movement are all functions of the neurons of the what?
What allows us to have a crude recognition of whether the sensation we are about to have is pleasant or unpleasant?
What disease leads to the massive degeneration of basal nuclei and later of the cerebral cortex?
What is the "emotional-visceral brain"?
What regulates the pituitary gland (an endocrine organ)?
What are the centers involved in olfaction?
What is olfaction?
Sense of smell
What disease is the overstimulation of the motor drive?
What are the important parts of the epithalamus?
Choroid plexus and pineal body
What is the middle meningeal layer?
What are the knots of capillaries within each ventricle?
What provides a pathway for ascending and descending tracts?
What plays a role in consciousness and the awake/sleep cycles?
Reticular activating system
What is a tiny canal that travels through the midbrain and connects the third ventricle of the diencephalon to the fourth ventricle below?
What consists of mostly fiber tracts and is involved in the control of breathing?
What is involved in motor control of the visceral organs?
What is the center for many drives and emotions?
What is compared to an automatic pilot, continuously comparing the brain's "intentions" with actual body performance by monitoring body position and amount of tension in various body parts?
What is the innermost membrane?
What is an important fiber tract area that contains many nuclei that regulate vital visceral activities? (Controls heart rate, blood pressure, breathing, swallowing, and vomiting.)
What does RAS stand for?
Reticular activating system
What plays a role in the regulation of body temperature, water balance, and metabolism?
What causes body movements to be smooth and coordinated? (Except for mine! Ahahaha)
Where is the primary somatic sensory area?
What are the 3 connective tissue membranes covering and protecting the CNS structures?
What disease is an example of basal nuclei problems and causes trouble initiating movement or getting muscles going?
Where are the thirst, appetite, sex, pain, and pleasure centers?
What is the outermost layer of the meninges?
What are the structures of the brain stem?
Medulla oblongata, midbrain, and pons
What does "pia mater" mean?
