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?
Learning Target:Compare skeletal, smooth, and cardiac muscle cells
and tissue.
Involuntary Voluntary Learning Target:Compare skeletal, smooth, and
cardiac muscle cells and tissue.
Striated Non-striated Learning Target:Compare skeletal, smooth, and
cardiac muscle cells and tissue.
Branched Not branched Tapered Learning Target:Compare skeletal,
smooth, and cardiac muscle cells and tissue.
Single nucleus Multinucleated Truth or Baloney 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. Truth or Baloney The two muscle
cells that contract without conscious thought are cardiac and
smooth. Truth Truth or Baloney Skeletal muscle cells have many
nuclei. Truth
Long skeletal muscle cells can have 1000 nuclei. Truth or Baloney
Without skeletal muscle tissue you would not have any facial
expression. Truth Skeletal muscles attach to facial bones such as
the zygomatic bone. Truth or Baloney The only type of muscle cell
lacking striations is smooth. Thats right- Its smooooth. What type
of cells are these? What type of cells are these? What type of
cells are these? 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
