1)
With a partner decide what action
(flex, extend, adduct, abduct) each of the following muscles provides
various parts of the body (A, K).
-
Keep in mind
the origin and insertion when making your
determinations.
-
Incorporate
the appropriate muscle and bone names, action, and simple explanation.
-
Example
1: The gracilis muscle is
an adductor because when it contracts it moves the
thigh toward the midline of the body.
-
Example
2: The palmaris longus
muscle is a flexor because when it contracts it
decreases the angle between the carpals and ulna.
I. Muscles that move the upper arm
A.
Pectoralis major
B. Latissimus dorsi
C.

|
II. Muscles that move the forearm

|
III. Muscles that move the thigh
A.

B.
Gluteus maximus
C.
Gluteus minimus & medius
|
IV. Muscles that move the lower leg
A.
Quadriceps femoris
B. Biceps
femoris
|
2) Take a tour of a muscle cell – Imagine you are a tour
guide. Describe the different parts of the cell and imagine it as an
amusement park, historical house, or national park.
3) Design a kinesthetic model for the sliding filament
mechanism where people are the following components: myosin, actin, Ca++.
What would they do during contraction, relaxation and rigor mortis?
4) Run through Physio-Ex Muscle Physiology Lab and play
with strength and frequency of stimulation to simulate different muscle
contraction patterns, e.g. multiple motor unit summation, treppe, etc.
5) Make a model of a muscle. Include the following
components in your model: (K).
a.
Myofilaments
b.
Sarcomeres
c.
Myofibrils
d.
Muscle fibers
e.
Fascicles
f.
Whole Muscle
