Type of matter represented
By #5.
What is white
matter?
Name of the structure
indicated by #7.
What is the
anterior horn?
Type of nerve tract
that carries
messages from the
brain to effector
organs.
What are
descending tracts?
The space in the
spinal cord that
contains
cerebrospinal fluid.
What is the central
canal?
The part of the white
matter (ie – one of
the three columns)
that carries sensory
information to the
brain.
What is the dorsal
(posterior) column?
The three main parts
of the brainstem,
from most inferior to
most superior.
What are medulla
oblongata, pons and
midbrain?
Containing pyramids, this
subregion of the brainstem
is responsible for vital
function such as heartrate,
blood pressure, breathing,
swallowing and many other
vital functions for life.
What is the
medulla oblongata?
Containing superior and
inferior colliculi, this
region of the brainstem is
primarily involved with
relaying information to the
auditory and visual cortex.
What is the
midbrain?
Meaning “bridge,”
this portion of the
brainstem relays
information between
the right and left
hemispheres.
What is the pons?
This group of nuclei is
responsible for
consciousness, and is
the group of cells that
are manipulated using
anesthetics.
What is the
reticular
formation?
Three main regions
of the
diencephalon.
What are the
thalamus,
epithalamus, and
hypothalamus?
Structure #5 – this structure is involved in
the onset of puberty in humans and
migratory patterns in animals.
What is the pineal
body?
This part of the diencephalon
is the most superior and
posterior portion of the
diencephalon. It is
responsible for our response
to odors and also plays a role
in the onset of puberty.
What is the
epithalamus?
This is the most
inferior part of the
diencephalon and
controls such things
as body temperature,
hunger and thirst.
What is the
hypothalamus?
Represented by #6 on the diagram – this is
the main dumping place for all sensory neurons
before they are redirected to the appropriate
place in the cerebrum.
What is the
thalamus?
The four lobes of
the cerebrum.
What are the
frontal, parietal,
temporal and
occipital lobes?
The folds and
intervening grooves
of the brain, in
that order.
What are gyri and
sulci?
Known as the
comparator, this
structure within the
brain helps with the
learning of new motor
movements.
What is the
cerebellum?
This is the largest
part of the brain.
What is the
cerebrum?
This fissure
separates the brain
into left and right
halves.
What is the
longitudinal
fissure?
The left side of the
body is controlled by
this cerebral
hemisphere.
What is the right
hemisphere?
This hemisphere of the
brain is much more
analytical.
What is the left
hemisphere?
Organelle within
the neuron
represented by
#6
What is the cell
body?
Type of neuronal pathway
illustrated above.
What is a reflex
arc?
This is the reason
why unmyelinated
axons are not as
effective as
myelinated axons.
unmyelinated axons
do not carry action
potentials (or
messages) as
quickly? They also
use more ATP in
the process!
FINAL JEOPARDY
Genetics
Explain the
difference between a
autosomal recessive
disease and a sexlinked recessive
disease.
Autosomal Recessive – must have
two recessive alleles on any
chromosome other than the 23rd
(sex pair)
Sex-Linked Recessive – girls must
have two recessive alleles on 23rd
pair, boys only have to have one
recessive allele.
