PLTW Biomed Final Exam Questions
And Answers. Verified And Updated.
Gross exam - answer✔✔a microscopic examination of the tissues that make up the brain. Can
see with your eyes and can be handled by hand.
medical examiners - answer✔✔what professional would perform a gross exam of organs?
histological exam - answer✔✔studies microscopic anatomy of tissues. needs to use a microscope
to see individual cells.
forensic histologist, histologist - answer✔✔what professional would perform a histological exam
of tissues?
nervous system - answer✔✔contains the brain, brain stem, spinal cord, and nerves. it is
responsible for receiving, interpreting, and reacting to signals from inside and outside the body.
uses chemical and electrical signals that transmit through the body, and responds to changes that
it detects. nerve signals control most bodily functions, including sensation, movement, and
digestive processes.
PNS - answer✔✔all the nerves in the body are part of the peripheral nervous system. the PNS
brings information from the outside world and from within the body to the CNS.
CNS - answer✔✔the brain and spinal cord are part of the central nervous system. the CNS
receives data from the PNS (outside world). the brain processes the information, makes decisions
about what to do, and sends signals back via the peripheral nervous system to bring about a
specific change.
frontal lobe - answer✔✔responsible for planning and organizing incoming information. also
controls behavior and emotion.
parietal lobe - answer✔✔crucial in integrating sensory and visual information.
temporal lobe - answer✔✔used for processing language and storing information in the long-term
memory.
occipital lobe - answer✔✔receives and processes sensory nerve impulses from the eyes.

, 2)Slices, Cross sections - answer✔✔2 methods used in performing a gross exam of a brain
during an autopsy
TBI(Traumatic Brain Injury) - answer✔✔a brain dysfunction caused by an outside force to the
head
CTE - answer✔✔a progressive degeneration, and/or death, of nerve cells caused by repeated
head injuries, such as repeated concussions
cells - answer✔✔basic unit for any organism such as a neuron that transmits information to other
cells
tissues - answer✔✔composed of cells, and if relating this to nervous tissue it has both neurons
and cells, which senses stimuli and transmits signals
organs - answer✔✔composed of tissue, for example, the brain is composed of nervous tissue,
which allows the brain to interpret stimuli
organ system - answer✔✔composed of multiple organs, for example, the nervous system is
composed of all the organs in the nervous system, which is responsible for all activities in the
nervous system
epithelial tissue - answer✔✔composed of epithelial cells aligned in sheets and connected to one
another. this tissue can be found lining the outer surfaces of all organs and blood vessels, in the
mouth, and on the surfaces of humans. this tissue works to absorb, secrete, protect, and sense for
us.
connective tissue - answer✔✔supports and connects other tissue types in the body. different
types of connective tissue work to hold organs in place, attach muscle to bones, link bones with
joints, or enable other tissues (like lungs) to stretch. it is found attached to and in between other
tissues types in the body.
nervous tissue - answer✔✔nerves, the spinal cord, and the brain are composed of nervous
tissues. this tissue, made up of specialized cells called neurons, works to receive, interpret, and
respond to signals.
muscle tissue - answer✔✔makes up the muscles found in the body. can be striated, smooth, or
cardiac
striated muscle - answer✔✔also known as skeletal muscle tissue, is attached to bones; voluntary
smooth muscle - answer✔✔found in the walls of internal organs; involuntary
cardiac muscle - answer✔✔found in the walls of the heart. this tissue provides the ability to
contract; involuntary
genome - answer✔✔complete sets of genes within an organism, and genes are made up of blood
