Piece of Mind
(all answers are found under this section heading in the text)
What is histology?
Study of Cells
Why is histology important?
Histology is important in medical
examinations because it lets
histologists to examine tissues for
specific characteristics that can
provide valuable insights into an
individual's health, disease, or
cause of death.
Describe what the medical
examiner found during their
autopsy of Anna’s body. Be sure
to also add this evidence to
your autopsy report.
The medical examiner found an
open wound on Anna's
forehead, measuring 1 inch
across, 0.5 inches wide, and 1/4
inches deep, along with a bruise
above her right eyebrow during
the autopsy. These findings
raised concerns about potential
brain damage or injury that
needed further investigation and
examination of Anna's brain
tissues.
Gross Anatomy
(scroll down to #3 under the heading above to find the answers for this section)
The Nervous System
Identify each picture as to whether it shows the CNS or the PNS.
Describe
each next to the picture. Label
the 3 main organs of the nervous system.
PNS:
Nerves: Transmit
information from the
outside world and from
within the body to the
central nervous system
for processing.
CNS:
Brain: Responsible for
various functions,
including cognition,
sensory perception, and
motor control.
Spinal Cord: Transmits
signals between the
brain and the rest of the
body.
Lobes of the Brain
(this is found at #4)
Double click on the brain to color code the 4 lobes of the brain
. Create a legend & color code the
corresponding boxes accordingly. In each of the 4 boxes, briefly describe the function of that lobe.
Frontal lobe-
This lobe is responsible
for various higher
cognitive functions,
including reasoning,
problem-solving,
emotions, and motor
skills.
Parietal Lobe-
The parietal lobe
processes sensory
information from the
body, such as touch,
pressure, temperature,
and pain. It plays a key
role in spatial awareness
and perception.
Temporal lobe-
The temporal lobe is
involved in auditory
processing, memory, and
the interpretation of
sounds and language. It
also plays a role in visual
perception.
Occipital Lobe - The
occipital lobe is primarily
responsible for visual
processing, including
interpreting visual
information from the
eyes.
A Gross Examination of Anna’s Brain
Explain what a gross exam is
inspecting all of the organs,
describing and measuring the
tissue, taking fingerprints,
obtaining tissue for histology.
Also, ordering CT or MRI scans
for the brain, and different body
List the 2 methods used in
performing a gross exam of a
brain during an autopsy
1)
MRI
This is found under terminology
under the section heading “A Gross
Examination of Anna’s Brain in the
text.
List & briefly describe the 2 kinds of
brain injuries we’re searching for in this
parts.
2)
Cross-sectioning the brain
to observe it
activity.
1)TBI:Brain dysfunction caused by an
outside force, usually a violent blow to
the head.
2) CTE:a progressive, degenerative
condition involving brain damage
resulting from multiple episodes of
head trauma
MRIs:
Label each MRI result below as normal control, TBI or CTE

Record your observations & initial conclusion about Anna based on macroscopic viewing of her nervous
tissues.
She had a TBI on the top of her head as well as near the bottom. From this ingo, i believe anna was hit by
something or hit her head on something leading to her death
