Beta waves
Give this one a try later!
Rhythmic, more irregular waves occurring during the awake and mentally
alert state.
Delta waves
Give this one a try later!
High-amplitude waves seen in deep sleep and when reticular activating
system is damped.
,Central sulcus
Give this one a try later!
Separates the frontal and parietal lobes.
Broca's area
Give this one a try later!
Located anterior to the inferior region of the premotor area. Present in one
hemisphere (usually the left). A motor speech area that directs muscles of
the tongue. Is active as one prepares to speak
Cerebral Hemispheres
Give this one a try later!
Form the superior part of the brain and make up 83% of its mass. Contain
ridges (gyri) and shallow grooves (sulci). Contain deep grooves called
fissures
Are separated by the longitudinal fissure. Have three basic regions: cortex,
white matter, and basal nuclei.
Characteristics of brain waves
Give this one a try later!
, An electroencephalogram (EEG) records the electrical activitym of the
brain as brain waves. Each person's brain waves are unique.
Define sympathetic/vasomotor tone.
Give this one a try later!
Constricts blood vessels and causes blood pressure to rise as needed.
Prompts vessels to dilate if blood pressure is to be decreased.
Exteroceptors
Give this one a try later!
Respond to stimuli arising outside the body. Found near the body surface.
Sensitive to touch, pressure, pain, and temperature. Include the special
sense organs.
Alzheimer's disease (degenerative brain disorder)
Give this one a try later!
A progressive degenerative disease of the brain that results in dementia.
Associated with aluminum build up in the brain.
Mechanoreceptors
