Bone Structure
1. Surface: covered
with tough, tight
fitting membrane
called periosteum
a) Blood vessels carry
nutrients into the bone
b) Important in the growth
and repair of bone
Bone Structure
2. Compact bone: under
the periosteum
a) Contains bone cells,
blood vessels, minerals
and elastic fibers
b) Elastic fibers keep bone
flexible
Rickets
Bones
2. Compact bone: under
the periosteum
a) Contains bone cells,
blood vessels, minerals
and elastic fibers
b) Elastic fibers keep
Osteoporosis
bone flexible
c) 2 diseases that result
from a lack of mineral
in bone: rickets,
osteoporosis
Bones
3. Spongy bone: found
towards the end of the
bone
a) Less compact
b) Has many small open
spaces that make the
bone light weight
Bones
4. Marrow: a fatty
tissue that fills the
cavities, or spaces,
in bones
a) Produces red blood
cells—2-3 billion per
second
b) Produces white blood
cells
Bones
5. Cartilage: thick
smooth layer of
tissue that covers
the ends of the bones
a) Flexible, important at
the joints because it
absorbs shock and
makes movement easier
What part of the bone contains
elastic fibers for flexibility?
1. Bone
marrow
2. Compact
bone
3. Cartilage

Joints
Any place where 2 or more bones
meet
Ligaments: tough
bands of tissue that
hold bones together
at the joints
Joints
Classification of Joints
a) Immovable: allows little
or no movement
Skull, pelvis
Joints
Classification of Joints
b) Movable: allows body to make a wide
range of movements

the ring of another
(arm, head)

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?

control these

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)
