EPPP BIOLOGICAL BASES OF BEHAVIOR
EXAMINATION REVIEW 2026 TEST
QUESTIONS AND ANSWERS 100% CORRECT
⩥ Parts of the Peripheral Nervous system. Answer: Somatic and
Autonomic Nervous system
⩥ Somatic nervous system. Answer: sends and receives sensory
messages that control voluntary motor movement of the skeletal muscles
⩥ The autonomic nervous system. Answer: controls the automatic or
involuntary bodily functions of the smooth muscles and glands including
digestions, heart rate, and breathing. The primary function is to maintain
homeostasis. It is divided into the sympathetic and parasympathetic
systems.
⩥ Sympathetic nervous system. Answer: body's "mobilizing system."
Fight or flight and is dominant during times of stress. when this
mobilizing system is activated, hormones are released into the
bloodstream which result in increased respiration, heart rate, and blood
pressure and decreases the process of digestion and elimination.
⩥ Parasympathetic nervous system. Answer: "energy conserving
system." dominant when a person is relaxed. The main function is
,maintenance, which is accomplished by slowing heart rate, bp, and
respiration while increasing digestion and elimination.
⩥ Which system, parasympathetic or sympathetic, is healthier to have
dominant?. Answer: parasympathetic
⩥ The central nervous system. Answer: spinal cord and brain with
sensory (afferent) neurons carrying info to the CNS and motor (efferent)
neurons carrying info away from the CNS to muscles and glands
⩥ The spinal cord 4 regions. Answer: cervical/neck,
thoracic/chest.,lumbar/back, and sacral region
⩥ paresis. Answer: Partial severing of the spinal cord
⩥ major divisions of the brain. Answer: cerebrum (cerebral cortex and
sub cortical areas), cerebellum, and brain stem
⩥ The cerebrum. Answer: involved with complex thought, perception,
and action. the outer layer is the cerebral cortex and the inside includes
the subcortical areas.
⩥ the cerebral cortex. Answer: least developed part of the brain at birth.
more developed in humans than other animals. full of folds (gyri) which
allow for expansion of the cortical surface without increasing brain size.
,divided into two halves-left and right which are connected by the corpus
collosum
⩥ 4 lobes of the brain. Answer: frontal, pareital, temporal, occipital
⩥ what separates the lobes? frontal and parietal lobes? temporal from
frontal and parietal?. Answer: elongated grooves (sulci); central sulcus;
lateral sulcus
⩥ The left hemisphere. Answer: dominant in 97% of people. dominance
refers to control over language (reading, writing, speaking, motor
control, etc). 90% of population is right handed and almost all are left
hand dominant, most left handers too.
involved in verbal memory and rational, analytical, logical, and abstract
thinking.
Damage to the left hemisphere may result in aphasia, language
impairments, apraxia, and difficulties for the right side of the body
Left is for Language and Logic
⩥ Right hemisphere. Answer: perceptual, visuospatial, artistic, musical,
and intuitive activities. also maintenance of body image and
comprehension of visual, facial, and verbal emotion.
, Damage may result in left side hemi-neglect, prosopagnosia, visual
spatial disturbances, and agnosia for musical sounds. also, indifference,
euphoria, hysteria, depression, mania, disinhibition, impolisitivty, and
abnormal sexual behavior
⩥ Frontal lobe. Answer: occupy largest portion of the brain
3 main divisions: prefrontal cortex, premotor area, motor area.
damage is most often caused by brain injury, stroke, or disease and may
result in paralysis, changes in personality, emotional lability,
perseveration, inattention, difficluty with problem solving, and brocas
aphasia (expressive lang)
⩥ prefrontal cortex, premotor area, and motor area (frontal lobe).
Answer: prefrontal: critical to personality, emotionality, inhibition,
planning and initiative, judgement, higher mental functions, and abstract
thinking.
premotor: planning movement
motor: voluntary muscle movement
left frontal lobe: broca's area (controls muscles that produce speech)
