1. gross exam a microscopic examination of the tissues that make up the brain.
Can see with your eyes and can be handled by hand.
2. medical examiners what professional would perform a gross exam of organs?
3. histological exam studies microscopic anatomy of tissues. needs to use a microscope
to see individual cells.
4. forensic histologist, histol- what professional would perform a histological exam of tissues?

5. nervous system contains the brain, brain stem, spinal cord, and nerves. it is respon-
sible 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.
6. PNS 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.
7. CNS 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.
8. frontal lobe responsible for planning and organizing incoming information.
also controls behavior and emotion.
9. parietal lobe crucial in integrating sensory and visual information.

10. temporal lobe used for processing language and storing information in the
long-term memory.
11. occipital lobe receives and processes sensory nerve impulses from the eyes.
12. 1)MRI(Magnetic Reso- 2 methods used in performing a gross exam of a brain during an
nance Imaging) autopsy
2)Slices, Cross sections
13. TBI(Traumatic Brain Injury) a brain dysfunction caused by an outside force to the head
14. CTE a progressive degeneration, and/or death, of nerve cells caused by
repeated head injuries, such as repeated concussions
15. cells basic unit for any organism such as a neuron that transmits infor-
mation to other cells
16. tissues composed of cells, and if relating this to nervous tissue it has both
neurons and cells, which senses stimuli and transmits signals
17. organs composed of tissue, for example, the brain is composed of nervous
tissue, which allows the brain to interpret stimuli
18. organ system 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
19. epithelial tissue 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.

20. connective tissue 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.
21. nervous tissue 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.
22. muscle tissue makes up the muscles found in the body. can be striated, smooth,
or cardiac
23. striated muscle also known as skeletal muscle tissue, is attached to bones; voluntary
24. smooth muscle found in the walls of internal organs; involuntary
25. cardiac muscle found in the walls of the heart. this tissue provides the ability to
contract; involuntary
26. genome complete sets of genes within an organism, and genes are made
up of blood
27. blood is made up of how does a single genome code for so many types of tissues?
4 different bases which
can create a variety. since
genomes are genes, genes
are responsible for deter-
mining the cell structure
and function by directing
synthesis of proteins and
coding RNA molecules.
