Back 31

association visual areas

Front 32

white matter

Back 32

fiber tracts of the cerebral hemispheres (part of the corpus striatum)

Front 33

commissural fibers

Back 33

have their cell bodies in the cortex of one hemisphere and pass in a great white sheet to the other hemisphere

Front 34

association fibers

Back 34

afferent or corticopetal fibers and efferent or corticofugal fibers

Front 35

afferent or corticopetal fibers

Back 35

radiate upward to the cortex from the thalamus and other subcortical areas (sensory)

Front 36

efferent or corticofugal fibers

Back 36

project downward from the cortex to subcortical areas (motor)

Front 37

meninges

Back 37

membranes surrounding the entire CNS

Front 38

dura matter

Back 38

(outer), thick, tough, and protective

Front 39

arachnoid matter

Back 39

thin weblike sheet of tissue

Front 40

pia matter

Back 40

(inner) thin and delicate

Back 41

space between arachnoid matter and pia mater; filled with cerebrospinal fluid

venticular system

Back 42

within the brain and spinal cord

Front 43

dystrophy

Back 43

disturbance in the shape and tone of muscle

Front 44

amyotrophic lateral sclerosis - lou Gehrig's disease

Back 44

a disease of the lateral corticospinal tract, destroying voluntary movement; a demyelinated disease

Front 45

multiple sclerosis

Back 45

a demyelinated disease involving several tracts (sensory and/or motor tracts)

Front 46

shingles

Back 46

a disease in the lateral horn of the spinal cord; inflamation of the dorsal root of the nerve; goes from the dorsal root into the lateral horn; characterized by tenderness of the skin and skin eruptions; caused by a virus

Front 47

parkinson's disease

Back 47

a disroder characterized by muscle tremors that occur when the person attempts to hold his or her hands and head still; it is due to a deficiency of dopamine in the basal ganglia.

Front 48

Alzheimer's Disease

Back 48

a neurodegenerative disorder that is characterized by profound personality changes and intellectual impairment including memory loss (affects the frontal cortex and hippocampus)
