STUDY GUIDE 2026 COMPREHENSIVE
QUESTIONS AND STEP BY STEP
SOLUTIONS
◉ Nervous system
Answer: the network of nerve cells and fibers that transmits nerve
impulses between parts of the body.
◉ Central Nervous System
Answer: the complex of nerve tissues that controls the activities of
the body. In vertebrates it comprises the brain and spinal cord.
◉ Peripheral nervous system
Answer: the nervous system outside the brain and spinal cord.
◉ Somatic Nervous System
Answer: deals with our voluntary control of muscles and our five
senses.
◉ Autonomic Nervous System
, Answer: the part of the nervous system responsible for control of
the bodily functions not consciously directed, such as breathing, the
heartbeat, and digestive processes.
◉ Electroencephalogram (EEG)
Answer: is a recording of the electrical waves of activity that occur in
the brain, and across its surface. Electrodes are placed on different
areas of a person's scalp, filled with a conductive gel, and then
plugged into a recording device.
◉ Positron emission tomography
Answer: which is similar to the MRI, is a scanning method that
enables psychologists and doctors to study the brain (or any other
living tissue) without surgery. PET scans use radioactive glucose
(instead of a strong magnetic field) to help study activity and locate
structures in the body.
◉ fMRI (functional MRI)
Answer: is a functional neuroimaging procedure using MRI
technology that measures brain activity by detecting changes
associated with blood flow.
◉ MRI (magnetic resonance imaging)
Answer: is a brain imaging technique that detects magnetic changes
in the brain's blood flow patterns.
