Muscular Dystrophy

• Weakness of the facial muscles/scapula that shows
  up before age 20
• Slow progression
• 20 of affected people use wheelchair
• Causes all around weakness
• No known cures

Smooth Muscles

• Occurs in small groups or sheets of overlapping
  cells tightly bound together(ex. Digestive tube,
  uterus, bladder, respiratory tract, vessels) can
  regenerate. Spindle-shaped cells with one central
  nucleus unstriated, no myofibrils, scattered
  myosin filaments, actin filaments attached to
  dense bodies. Contraction produces a cellular
  twisting motion. Action is slower, but longer
  lasting, aerobic, resist fatigue. Much of our
  internal organs are made up of smooth muscles.
  They are found in the urinary bladder,
  gallbladder, arteries, and veins. The smooth
  muscles are controlled by the nervous system and
  hormones. We cannot consciously control the
  smooth muscle that is why they are often called
  involuntary muscles.

Skeletal Muscles

• Bundles of cells run in parallel(fasicle) in
  various arrangements such as spindles, bands, or
  sheetstypically between 2 bones and across a
  joint. Connective tissue is subdivided into three
  parts which together form part of the deep
  fascia, merge to form tendons and aponeurosis.
  Very vascular. There are three skeletal fiber
  types Red slow-twitch fibers, White fast-twitch
  fibers, and Intermediate fibers. The skeletal
  muscle makes up 40 of an adults body weight. It
  has the stripe-like markings, or striations. The
  skeletal muscle is composed of long muscle
  fibers. Each of these muscles fibers is a cell
  which contains several nuclei. The nervous system
  controls the contraction of the muscle. Many of
  the skeletal muscle contractions are automatic.
  However we still can control the action of the
  skeletal muscle. And it is because of this reason
  that the skeletal muscle is called voluntary
  muscle.

Cardiac Muscles

• Branching network of cells forming layers that
  wind in overlapping spirals to from the heart.
  Cells connected by intercalated discs containing
  desmosomes and gap junctions. A c.t. layer
  separates atria from the ventricles. Inherent
  rhythmic contraction, pacemaker cells, gap
  junction connections form functional synctium of
  two atria and of the two ventricles, heart rate
  moderated by ANS. The cardiac muscles are the
  muscle of the brain itself. The cardiac muscle is
  the tissue that makes up the wall of the heart
  called mydocardium. Also like the skeletal
  muscles , the cardiac is striated and contracts
  through the sliding filament method. However it
  is different from other types of muscles because
  it forms branching fibers. Unlike the skeletal
  muscles, the cardiac muscle is attached together
  instead of being attached to a bone.

• The skeletal system provides support, protection,
  bodily movement, blood for the body, and it
  stores minerals. It consists of 206 bones that
  the tissue and organs are attached. All of the
  main organs are protected by the skeletal
  system(brain-skull heart-rib-cage). Muscles are
  connected to bones by tendons, and bones are
  connected to each other by ligaments. This is
  what allows our body to move. Around 2.5 million
  red blood cells replace old ones each second by
  the bone marrow, which is in only some bones.
  Bones store the minerals, calcium and phosphorus.
  When there is extra of either of these two, it
  all builds up in the bones. When these minerals
  in the blood run low, it is taken from the bones
  and distributed into the blood.

• Osteosarcoma is the most common found bone cancer
  in children. Osteosarcoma is diagnosed in 4 out
  of every 1 million people each year, and it
  happens to males more often than females. There
  is currently no known cure. To treat this
  disease the bone and its surrounding tissue must
  be removed. This may be treated with an
  amputation, or a limb salvage procedure.
  Chemotherapy is also necessary to treat this
  disease. This prevents the tumor from spreading.
  Drugs have come out which help to make the tumor
  smaller and to prevent it from spreading.
  Children with localized Osteosarcoma have a 70
  chance for survival, but children with metastatic
  Osteosarcoma have only a 30 chance of living.

15
Osteoporosis

• Bone condition with the symptoms of bone
  fragility, pain, fracture, and death from
  fracture complications
• 40 of people with this disease are men
• 25 million Americans are affected
• No cure yet but there are many projects working
  to solve this problem.
• Could be prevented by getting lots of calcium

Joints

• Immovable (2 pieces of bone directly connected
  with no space in between them) Joints in the
  skull that cannot be moved
• Ball/Socket (ex. The shoulder) Shoulder and hip
  allows movement in almost full circle
• Gliding Joint (wrist and ankle, two bones joining
  one larger bone) Wrist and ankle, back and forth
  motion
• Pivot Joint (hand) Ends of the radius, and ulna,
  rotates with a ring of bone and fibros tissue
• Hinge (knee/elbow) Allows movement, only back and
  forth
