PLTW Biomed Final Exam | 100% Correct
Answers | Updated 2026 Edition
gross exam --SOLUTION--a microscopic examination of the tissues that make up the brain. Can see with
your eyes and can be handled by hand.
medical examiners --SOLUTION--what professional would perform a gross exam of organs?
histological exam --SOLUTION--studies microscopic anatomy of tissues. needs to use a microscope to see
individual cells.
forensic histologist, histologist --SOLUTION--what professional would perform a histological exam of
tissues?
nervous system --SOLUTION--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 --SOLUTION--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 --SOLUTION--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 --SOLUTION--responsible for planning and organizing incoming information. also controls
behavior and emotion.
parietal lobe --SOLUTION--crucial in integrating sensory and visual information.
temporal lobe --SOLUTION--used for processing language and storing information in the long-term
memory.
occipital lobe --SOLUTION--receives and processes sensory nerve impulses from the eyes.
1) MRI(Magnetic Resonance Imaging)
2) Slices, Cross sections --SOLUTION--2 methods used in performing a gross exam of a brain during
an autopsy
TBI(Traumatic Brain Injury) --SOLUTION--a brain dysfunction caused by an outside force to the head
CTE --SOLUTION--a progressive degeneration, and/or death, of nerve cells caused by repeated head
injuries, such as repeated concussions
cells --SOLUTION--basic unit for any organism such as a neuron that transmits information to other cells
tissues --SOLUTION--composed of cells, and if relating this to nervous tissue it has both neurons and
cells, which senses stimuli and transmits signals
organs --SOLUTION--composed of tissue, for example, the brain is composed of nervous tissue, which
allows the brain to interpret stimuli
, organ system --SOLUTION--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 --SOLUTION--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 --SOLUTION--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 --SOLUTION--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 --SOLUTION--makes up the muscles found in the body. can be striated, smooth, or cardiac
striated muscle --SOLUTION--also known as skeletal muscle tissue, is attached to bones; voluntary
smooth muscle --SOLUTION--found in the walls of internal organs; involuntary
cardiac muscle --SOLUTION--found in the walls of the heart. this tissue provides the ability to contract;
involuntary
genome --SOLUTION--complete sets of genes within an organism, and genes are made up of blood
blood is made up of 4 different bases which can create a variety. since genomes are genes, genes are
responsible for determining the cell structure and function by directing synthesis of proteins and coding
RNA molecules. --SOLUTION--how does a single genome code for so many types of tissues?
