1

Muscular System...

- Made of muscle
- 650 muscles, about 40% of are body weight
- All muscles composed of muscle fibers
-Provides movement, body heat, storage of energy, protect the sheets of muscle, protect internal organs, alignments, position and shape of the body.

2

Skeletal System...

- Made of bone, joints, tendons, cartilage and ligaments
- 206 bones in adults
- Provides protection (which surrounds body cavity), a framework for the body (shape & support), assist with movement (a places for muscle to attach to) and storage of minerals (calcium, potassium; gets release into the circulation as your body needs it)

3

Musculoskeletal System...

- Help the body move, protect internal organs and keep us upright

4

Skeletal muscle...

- Voluntary: its under are conscious control
- Appear striated or stripe
- Provides movement of are body

5

Smooth muscle...

- Involuntary: it operate automatically
- Appears non-striated
- Help with mobility functions

6

Cardiac muscle...

- Only found in the heart
- Involuntary: it operate automatically
- Causes contraction of heart muscle to maintain blood flow

7

Excitability...

- The ability to receive and response to a stimulus

8

Contractility...

- The ability to shorten or contract
- This is when the movement occurs

9

Extensibility...

- The ability to stretch

10

Elasticity...

- Able to stretch and return to its original shape and length

11

Joints hold...and measure by...

- Bones firmly together, but still allow movement
- A degree like how much range of motion (ROM) someone can do

12

Ligaments...

- Allow movement in some directions while restricting it in other directions
- Hold bones together either around or across a joint to keep it in place
- Fiber band and connected tissue
- Can tears and sprains

13

Tendons...

- Non-elastic
- Go with a lot of force
- Can tears and sprains

14

Fascia...

- Specialized flat band of tissue located just below the skin that covers and separates underlying tissues

15

Cartilage...

- Semi-smooth, dense, supporting connective tissues that is found at the ends of the bones
- Absorbs energy for force of weight
- Press against the joint that prevents injury to joint, bone and cartilage.

16

Bursae make it...

- possible for tissue to glide over each other without creating friction

17

Back pain is...

- A very common condition
- Muscular and skeletal complain

18

Symptoms of back pain include...

- Joint stiffness, inflammation, swollen, weight loss (orthopedic symptom), bone mass loss, form mate of bone, fatigue, weakness, tenderness and swollen joint and bone

19

Back pain Tx depend on...

- The condition, immobility, range of motion(ROM) and loss of motion

20

Fibromyalgia is...

- Chronic, very common
- It's pain associated with stiffness and tenderness
- Will affect muscle, tendon and joints throughout the body

21

Symptoms of Fibromyalgia include...

- Restless sleep (can't get comfortable and constant pain), chronic pain(like depression and anxiety), stiffness, loss of motion (can't brush teeth or open a jar)
- Symptoms can be very non-specific

22

What is the cause of Fibromyalgia and what kind of test can diagnose it?

- Cause is unknown, difficult to diagnose
- Can take a long time to diagnose
- No specific test studies can diagnose it
- Usually you go to the lab to rule out other health conditions
- You may look fine on the outside

23

Tx for Fibromyalgia...

- Warm shower, sitting in a warm pool, ice bath, walking, talking to someone or medications (take it early in the AM) for constant pain and help with stress
- Swimming, low impact exercise
- Get out and move for physical and mental pain
- Try and see what works

24

Lordosis is...

- Excessive inward curvature of the spine
- Happen in the lower back

25

Cause of Lordosis...

- Pregnancy, obesity and some have it naturally, rapid skeletal growth that occurs without the necessary natural stretching of posterior soft tissues

26

Symptoms of Lordosis...

- Low back pain, muscle fatigue, tightness, numbness in leg, nerve in pitchmen

27

Tx for Lordosis...

- Brace, surgery, PT, spinal fusion, displacement osteotomy
- Weight loss and exercise to strengthen abdominal muscles, if obesity is the cause

28

Kyphosis is...

- Abnormal excessive outward curve of the spine in the upper back (Buffalo hump)
- Very mild to very sever

29

Cause of Kyphosis...

- In children: believed to be developmental, tumors or tuberculosis of the vertebral bodies and ankylosing spondylitis
- Some are brought on by medical conditions like parkinson

30

How is Lordosis diagnose?

- X-ray, physical exam, and listening to the symptoms
