Nervous System II
norepinephrine
adrenergic synapses release the neurotramsmitter
cerebellum
automatic processing center responsible for programming and fine-tuning movements controlled at the conscious and subconscious levels
trigeminal
cranial nerve that has three branches
loss of ability to speak
if Broca's area is damaged, what might result?
L1 or L2
in adults, the spinal cord usually extends to which level?
medulla oblongata
major centers concerned with autonomic functions, such as heart rate, blood pressure, and respiration
olfactory
only nerve that is attached to cerebrum
longitudinal fissure
separates the two cerebral hemispheres
trigeminal
teeth, muscles of mastication
diencephalon
acts as a switching and relay center for integration of conscious and unconscious sensory information and motor commands
autonomic
nervous system that provides involuntary regulation of smooth muscle, cardiac muscle, and glandular activity
corpus callosum
primary connection between cerebral hemispheres
cerebrum
region of the brain that is involved in conscious thought and intellectual function as well as processing somatic sensory and motor information
pineal gland
secretes melatonin
pia mater
the only layer of the meninges that is in direct contact with the surface of the brain
cerebellum
the part of the CNS that adjusts voluntary and involuntary motor activities on the basis of sensory information and stored memory of previous movements
diencephalon
the thalamus is the largest portion of which major brain region?
oculomotor
3 out of 4 rectus muscles of eye
vagus
damage to the ________ nerve, which is vital for the autonomic control of visceral function, could result in death
sympathetic division
division of ANS that usually stimulates tissue metabolism
vestibulocochlear
ear
increased secretion by digestive glands
effects produced by the parasympathetic branch os the ANS include
limbic system
establishes emotional states
tracts
bundles of CNS axons that share a common origin, destination, and function
medulla oblongata
structure that contains cardiovascular and respiratory rhythmicity centers
cerebral aqueduct
the CSF-filled canal in the midbrain
frontal lobe
the area anterior to the central sulcus
temporal lobe
the cortex inferior to the lateral sulcus
I, II, and VIII
the cranial nerves whose primary function is special sensory
vagus
thoracic and abdominal organs
hypoglossal
tongue muscles
occipital lobe
where the visual cortex is located
