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
