Ch 7: The Structure Of The Nervous System Flashcards
Forebrain (prosencephalon)
Is a primary vesicle that is in control of perceptions conscious awareness, cognition, and voluntary action
Cerebral cortex
Most important structure in the forebrain
Cortical neurons receive what
Sensory information, form perceptions of the outside world, and common voluntary movements
Neurons located in the ____ receive information from. Ella that sense chemicals in the nose and relay information causally to a pet of the cerebral cortex for analysis
Olfactory bulbs
How do the thalamic neurons send axons to the cortex?
Via internal capsule
Damage to the basis ganglia causes what?
Disrupts the ability to initiate voluntary movement
What does the hypothalamus do?
Controls the visceral (autonomic) nervous system
What does the visceral (autonomic) nervous system do?
Regulate bodily functions in response to the needs of the organisms.
What are the white matter structures?
Corpus callosum, cortical white matter and internal capsule
What does the corpus callosum do?
It is continuous with the cortical white matter and forms an axonal bridge which links cortical neurons of white matter and forms an axonal bridge that links cortical neurons of the two cerebral hemispheres
What is the cortical white matter?
It contains all the axons that run to and from the neurons in the cerebral cortex
How much does the midbrain differentiate?
It differentiates relatively during Brian development
What does the dorsal surface of the mesencephalic vesicle become?
A structure call the tectum
The floor of the midbrain becomes what?
The tegmentum
The tectum differentiates into what two structures?
The superior colliculus and the inferior colliculus
