Transcript Skeletal and Muscular System

Skeletal and
Muscular
System
Skeletal System
Interacts
with
muscular system for
movement of the body
Coordinated by
nervous system
What is Cartilage?
Cartilage
is connective
tissue that is more
flexible than bone
Cushions bones
Cartilage
Bones
1.
Supports body
2. Protects Organs
3. Produce new red
blood cells in the bone
marrow
Bones
4.
Enables you to
move
5. Stores certain
materials until your
body needs them.
Vertebrae
The
26 small bones
that make up the
backbone
What is a Joint?
A
joint is the place
where two bones come
together
Joints help the skeleton
move the body.
What are the two kinds of
joints in the body?
The
two kinds of
joints in the body are
immovable and
movable joints
What are the two main
immovable joints in our
bodies?
Bones
of the skull
Joints that attach the
ribs to the sternum
Immovable Joint
Joint
Kind of Motion
Where It’s Found
in the Body
Hinge
Forward or
backward motion
Knee
Elbow
Ball-&Socket
Pivot
Greatest range of
motion
Shoulder Blade
Hips
Gliding
One bone to slide
over another
One bone to rotate Neck
around another
Wrist
Ankles
When do bone cells form
new bone tissue?
New
bone tissue
forms to fill the gap
between the broken
ends of the bone.
Ligaments
The
bones in movable
joints are held together
by strong connective
tissues is called
LIGAMENTS
Connect bone to bone
Ligaments
Tendons
Attach
bones
muscles to
Marrow
The
spaces in bone
that contain a soft
connective tissue is
called MARROW
Bone Marrow
Muscles
Motion of organs
Locomotion of Body
Interacts
with all organ
systems causing
movement of tissues and
organs
Muscular System
3 Types of Muscles
Type
Skeletal Muscles
of striated muscle,
attached to the skeleton.
Facilitate movement, by
applying force to bones and
joints; via contraction.
Contract voluntarily, although
they can contract involuntarily.
Skeletal Muscle
Cardiac Muscle
Type
of striated muscle
found within the heart.
Function is to "pump"
blood through the
circulatory system by
contracting
Cardiac Muscle
Smooth Muscle
Type
of non-striated
muscle, found in organs
blood vessels, the
bladder, the uterus, and
the digestive system
Smooth Muscle
Arthritis
Painful
Inflammation of
freely movable joints.
Immune system attacks
tissues around joints
Symptom stiffening &
swelling
Gout
Systemic
disease
(throughout body)
Build up of uric acid
Settles in joints causing
inflammation and swelling
Tendonitis
Inflammation
the tendons
in
Osteoporosis
A
condition in which
the body’s bones
become weak and
break easily
