Muscle Cells and Tissue
Time for a Movie
Discovery Channel Pushing the Limits: Muscle Fibers
10:39: Describe skeletal muscle fibers (muscle cells).
11:21 How many skeletal muscle fibers do we normally use at any one
time?
12:19 What body structure is needed to trigger our skeletal muscle
fibers?
13:15 When is the only time we can trigger all of our skeletal muscle
fibers at once?
13:40 What is the cost of using all of our skeletal muscles at once?

Single nucleus
Multinucleated
Single nucleus
True or False
Smooth muscle is found
primarily in the
musculature of the
extremities.
Baloney
Smooth muscle is found
lining organs and it is
the type of muscle
making up the iris of
the eye.
True or False
2. The two muscle
cells that contract
without conscious
thought are cardiac
and smooth.
Truth
True or False
3. Skeletal muscle
cells have many
nuclei.
Truth
Long skeletal muscle
cells can have 1000
nuclei.
True or False
4. Without skeletal
muscle tissue you
would not have any
facial expression.
Truth
Skeletal muscles attach
to facial bones such
as the zygomatic
bone.
True or False
5. The only type of
muscle cell lacking
striations is
smooth.
That’s right- It’s
smooooth.

Tissues associated with the
muscular system
Skeletal muscle tissue
Supplies nutrients and oxygen to muscle
tissue and carries away waste products
Covers and holds muscles in place (fascia)
Aids in skeletal movement and facial
expression
Forms tendons
Transmits impulses and messages to
muscles
Contracts hollow internal organs
Allows for rhythmic contraction of the
heart
