Flashcards in The Brain Deck (42)
What is the frontal lobe responsible for?
Primary motor activity, behavior, speech production, emotional changes (flatness)-- relating to behavior
What is the parietal lobe responsible for?
Primary somatosensory and proprioception; association of somatosensory, vision, audition; formation of egocentric space and sense of self.
What is the temporal lobe responsible for?
Audition, olfaction, memory
What is the occipital lobe responsible for?
What is the end of the spinal cord called?
Which part of the spinal cord are the sensory nerve tracts?
Which part of the spinal cord are the motor neurons?
What 3 structures make up the brainstem?
Midbrain, Pons, and Medulla oblongata
What is the medulla oblongata responsible for?
Respiration, cardiac center, vasomotor center, reflex centers for vomiting, swallowing, coughing, sneezing
What are the corticospinal tracts?
Where are the pyramids?
What is the decussation of the pyramids?
Where motor fibers from the left hemisphere cross to the right and vice versa.
What CN nuclei are in the medulla oblongata?
CN IX, X, XI, XII (glossopharyngeal, vagus, accessory, and hypoglossal)
What does the name "pons" mean?
What does the pons contain?
Fiber tracts connecting the medulla and cerebellum with upper portions of the brain
What is the pons responsible for?
Respiratory centers that work with the medulla
What CN nuclei are in the pons?
CN V (motor), VI, VII, and part of VIII (trigeminal, Abducens, facial, vestibulocochlear)
Where is the substantia nigra located?
What does the midbrain contain?
cerebral pundlecles; connecting tracts from pons to cerebellum
What is the Substantia Nigra?
Dopamine producing regions
What is the Corpora quadrigemina?
The masses that make up the superior and inferior colliculi.
where is the Corpora quadrigemina?
What CN nuclei are in the midbrain?
CN III, IV, V (sensory) (oculomotor, trochlear, trigeminal)
What ventricular structure passes through the midbrain?
What ventricular structure is located in the medulla?
Part of the 4th ventricle
What is the cerebellum responsible for?
balance/posture, learning of motions, cognitive functions, motor coordination
What will damage to the cerebellum result in?
lack of coordination in gait, speech, etc
What are the hemispheres of the cerebrum connected by?
The corpus callosum
What is the cerebral cortex responsible for?
sensorimotor integration and perceptive qualities of our experiences
What is a gyrus?
convolution of cortex
what is a sulcus?
gap between the gyri
What is the longitudinal fissure?
divides the brain into the right and left hemispheres
What is the Lateral (Sylvian) sulcus?
separates temporal lobes from the frontal lobes
What is the central sulcus?
Separates frontal lobe from the parietal lobes
Where is the sensory homunculus represented?
postcentral gyrus of the parietal lobe
Where is the motor homonculus represented?
on the pre central gyrus of the frontal lobe
What is received by the thalamus?
all sensory stimuli, except olfactory
What happens to the sensory stimuli from the thalamus?
integrated and relayed through thalamocortical radiations to specific cortical areas
What comprises the walls and floors of the third ventricle?
What is the hypothalamus chief region for?
integration of the autonomic nervous system
What does the hypothalamus do?
Regulates water balance, body temperature, and thirst
