Lab 1: Organization of the Human Body Activities

 

Activity 1.1

You will work in pairs for this activity.  You and your partner should adopt the anatomical position; then ask yourselves if this is how you will consciously or unconsciously stand. If you are to look straight ahead, which part(s) of your body are you not likely to orient the way you have in the anatomical position?

Review the diagrams on directional terms and surface anatomy again. Appreciate and understand that the right side of your partner facing you is your left side when you are each in the anatomical position.

Now practice using directional terms by completing the sentences below:

1. The nose is _____________________ to the cheeks but _____________ to the mouth.
2. The foot is ________________ to the knee but the elbow is _______________ to the wrist.
3. All the components of the integumentary system are ___________ to the skeletal system.
4. Nipples on male and female breasts are ____________ to the breastbone.

For the FOUR terms that you are to label in Diagram 3 below, define or describe each.

Diagram 3:

2. Term:

Using the word bank in the diagram below, label the surface anatomical parts/structures.

 

 

 

Activity 1.2

You can aggregate in groups of FOUR for this activity.  It is about planes and sections.

You will be provided apples for this activity. Each group of four should stand their apple placing the part where the stalk was on the table.  With a scalpel etch eyes, a nose and mouth on the upper part of the apple.  The side with the face represents the anterior side and you have a top and bottom part.

First make a mid-sagittal cut through the apple. Using directional terms what parts of the apple do you now have? ____________________________________________________.

Next make a coronal cut while holding the cut pieces together (we do not want to waste apples unnecessarily). What parts of the apple do we now have again using directional terms?

______________________________________________________

Wrap a tape round the upper and lower pieces of apple (they should be four at this stage; then make a transverse cut.  If you imagine that the apple is still whole, what parts of the apple do you now have; use directional terms? _______________________________________________________

Does this make you appreciate orientation-wise planes and sections? Yes ____  No__________

Now in your own words (do not copy the notes) define or describe:

1. i) Midsagittal section____________________________________________________________________

How is this different from parasagittal section?______________________________________________

____________________________________________________________________________________

1. ii) coronal section ______________________________________________________________________

iii) transverse section ___________________________________________________________________

Using the human torso model in class, determine which of the sections would leave the face intact when you finish making them. _________________________________________________________________

 

Activity 1.3

Which cavity of the human body houses the brain? ___________________________________________.

This cavity is ventral to the dorsal cavity name its two major sub-cavities:

1. ________________________________    ________________________________________

The two layers of a serous membrane are:

1. __________________________ layer which is found sticking to the organ surface, and
2. __________________________ which is closer to the body wall.

 

 

 

Activity 1.4

Label the planes in diagram 1. Which plane passes through the body’s midline?

Label the quadrants in Diagram 2.

Which organ(s) would you find exclusively in each of the four quadrants?

1.

2.

3.

4.

Now draw your own human torso below indicating the location/position of the diaphragm and umbilicus (navel).  On the drawing show and label to 9 abdominopelvic regions
