Functions
of the Muscular System
1. Muscles are the motors that move
body parts
a) Muscles always
pull, they
never push
Functions
of the Muscular System
1. Muscles are the motors
that move body parts
a) Muscles always pull,
they never push
b) Pairs of skeletal
muscles work
together: 1 muscle
contracts while the
other muscle relaxes
Functions
of the Muscular System
2. Maintain homeostasis by
keeping body temperature
constant
a) When muscles contract, chemical
energy
(glucose) is converted
to thermal energy (heat)
When sitting, what must your thigh
muscles do to straighten your legs?
a) One muscle
contracts &
the other
relaxes.
b) Both musts
contract.
c) Both muscles
relax.
d) One must pulls
on the bone &
the other pulls
on the first
muscle.
Groups of Muscles
1. Voluntary—you can
control these
Arms, legs, hands, face
2. Involuntary—you can’t control
these, don’t have to decide to
make these muscles work
Muscles around heart
Types of Muscle Tissue
1. Skeletal muscle
a) Most numerous in body
b) Voluntary
c) Looks striped (striated)
d) Contract quickly, tire easily
e) Attached to the bones by
tendons (thick bands that
pull on the bone as the
muscle contracts)
Types of Muscle Tissue
2. Smooth muscle
a) Found in: walls of stomach,
intestine, uterus, etc.
b) Involuntary
c) No striations
d) Contracts and relaxes slowly
Types of Muscle Tissue
3. Cardiac muscle
a) Only found in heart
b) Involuntary
c) Has striations
d) Contracts 70 times per minute
(heartbeat)

muscular system?

Functions of the
Integumentary System
1. Forms a protective covering over
the body

Which is NOT a function of the
integumentary system?
a) To prevent
substances from
entering the body
b) To help keep body
temperature
stable
c) To remove wastes
from the body
d) To absorb oxygen
into the body
Layers of Skin
1. Epidermis = surface layer
a) Cells on top are dead
b) New cells are
constantly
produced at the
bottom
c) Cells produce
melanin
(pigment that
gives you skin
color)
Layers of Skin
2. Dermis = layer under epidermis
a) Thicker than epidermis
b) Contains blood
vessels, nerves,
oil and sweat
glands
