PLTW Biomed Final Exam UPDATED Exam
Questions and CORRECT Answers
gross exam - CORRECT 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 - CORRECT ANSWER - what professional would perform a gross
exam of organs?
histological exam - CORRECT ANSWER - studies microscopic anatomy of tissues. needs
to use a microscope to see individual cells.
forensic histologist, histologist - CORRECT ANSWER - what professional would perform
a histological exam of tissues?
nervous system - CORRECT 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 - CORRECT 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 - CORRECT 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 - CORRECT ANSWER - responsible for planning and organizing incoming
information. also controls behavior and emotion.
,parietal lobe - CORRECT ANSWER - crucial in integrating sensory and visual
information.
temporal lobe - CORRECT ANSWER - used for processing language and storing
information in the long-term memory.
occipital lobe - CORRECT ANSWER - receives and processes sensory nerve impulses
from the eyes.
1)MRI(Magnetic Resonance Imaging)
2)Slices, Cross sections - CORRECT ANSWER - 2 methods used in performing a gross
exam of a brain during an autopsy
TBI(Traumatic Brain Injury) - CORRECT ANSWER - a brain dysfunction caused by an
outside force to the head
CTE - CORRECT ANSWER - a progressive degeneration, and/or death, of nerve cells
caused by repeated head injuries, such as repeated concussions
cells - CORRECT ANSWER - basic unit for any organism such as a neuron that transmits
information to other cells
tissues - CORRECT ANSWER - composed of cells, and if relating this to nervous tissue it
has both neurons and cells, which senses stimuli and transmits signals
organs - CORRECT ANSWER - composed of tissue, for example, the brain is composed
of nervous tissue, which allows the brain to interpret stimuli
, organ system - CORRECT 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 - CORRECT 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 - CORRECT 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 - CORRECT 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 - CORRECT ANSWER - makes up the muscles found in the body. can be
striated, smooth, or cardiac
striated muscle - CORRECT ANSWER - also known as skeletal muscle tissue, is attached
to bones; voluntary
smooth muscle - CORRECT ANSWER - found in the walls of internal organs; involuntary
cardiac muscle - CORRECT ANSWER - found in the walls of the heart. this tissue
provides the ability to contract; involuntary
genome - CORRECT ANSWER - complete sets of genes within an organism, and genes
are made up of blood
