2. (15 points) Draw the following nervous traces on the
illustration below. When drawing the neurons, you
must clearly draw the location of their cell body and
synaptic junctions. The synaptic junctions must be
represented like the pictures that you studied in the
lecture manual. You must also label the neurons.
At Level 1, draw and label a reflex pathway to a
skeletal muscle served by the ventral ramus. Color
each neuron a different color and clearly show the cell
bodies and synapse locations.
Level 1
At Level 2, draw and label a sympathetic neuron
reflex from and to a blood vessel in the epaxial body
wall. Color each neuron a different color and clearly
show the cell bodies and synapse locations.
Level 2
At Level 3, draw and label a sympathetic neuron
pathway from and to a blood vessel in the descending
colon. Color each neuron a different color and clearly
show the cell bodies and synapse locations.
Level 3
At Level 4, draw and label a parasympathetic neuron
pathway from and to the taenia coli muscle of the
descending colon. Color each neuron a different color
and clearly show the cell bodies and synapse locations.
Level 4
In this illustration what spinal levels are represented
by:
Level 1 _____________________________
Level 2 _____________________________
Level 3 _____________________________
Level 4 _____________________________

3. (9 points) One of the major themes of this portion of the course was the pattern of the body wall muscles
of the trunk. The table below depicts the pattern of design of the body wall and has an empty box for each
muscle in the body wall. Fill in each of the boxes with the correct muscle to complete the table.
Pattern Ventral Lateral
Outermost

4. (14 points) Trace a red blood cell on a continuous route from the heart to the right transversus thoracis muscle then back to
the heart then to the greater curvature of the stomach at its pyloric end then back to the heart and then to the right testis then back
again to the heart and then to the right subcostal muscle in the uppermost intercostal space and then once more back to the heart.
There are no blockages so your trace must traverse normal pathways of flow. Your trace must consist of a columnar list of
the vessels through which the red blood cell passes as it moves to and from each of these structures. Use the space in the columns
below. You do not need to list the structures of the heart in the trace, nor do you have to write arterioles, capillaries, venules.
Heart
Right testis
Right transversus thoracis muscle
Heart
Heart
Right subcostal muscle in
upper intercostal space
Greater curvature of pyloric end of stomach
Heart

7. (11 points) Fill in the blanks in the sentences below.
The ___________________________ nerve distributes parasympathetic efferent neurons to the thoracic
viscera and arises from the _____________________________.
Name one primary retroperitoneal organ. __________________________________________________
Name four secondary retroperitoneal organs:
_____________________________________________________

The _______________________ is the peritoneal fold that runs between the stomach and the liver.
At ovulation the egg breaks the surface of the ovary and enters the _______________________________.
What named cells form the myelin sheaths of the peripheral nervous system ______________________
The adoral branch of the splenic artery is the _____________________________________
8. (5 points) In the boxes below pick a color and fill the box and then clearly illustrate each structure on the
picture with that color. You must clearly color the entire extent of each of the named structures. Also, with
a labeled arrow clearly indicate the location of the pleural cavities and pericardial cavity. In the spaces
below list three mediastinal structures that are visible in this illustration other than the heart and its anatomy.
visceral pleura
parietal pleura
visceral pericardium
parietal pericardium
fibrous pericardium
Mediastinal structures:
