Muscle

2. Gross Anatomy of Muscle
Lab: Identification of
individual muscles
Some: Origin
Insertion
Function
Lecture: Not responsible
for identification
But: Should understand
some concepts

3. (Should understand some concepts)
1. Each muscle has a size
and shape specialized for
its function

4. (Should understand some concepts)
1. Each muscle has a size
and shape specialized for
its function
2. Muscles often act in groups

5. (Should understand some concepts)
1. Each muscle: size and shape specialized for its function
2. Muscles often act in groups
3. Each muscle may
have different
functions in
different types of
movement

6. (Each muscle may have different functions in different types of movement)
1. Prime mover
or agonist
2. Synergist
3. Antagonist
4. Fixator

7. (Each muscle may have different functions in different types of movement)
1. Prime mover
or agonist
2. Synergist
3. Antagonist
4. Fixator

8. Go over muscles you studied in lab
and
Be sure you understand how these act as agonists, antagonists, synergists, and fixators.
On lecture exams: You may be asked to identify muscles with each of these four functions at the shoulder
elbow
wrist
hip
knee
ankle
