Muscle flashcards!

Please:

1. Cut out flashcards2. Hole punch3. Divide into upper and lower4. Combine lower muscles onto your skeletal flashcard ring5. Grab colored pencil

We will go through the upper muscle 2 times1. First time just to label

2. Second time to put in movements

Label each card: anterior/posterior/medial/lateral as it comes up on the screen.

Understanding Muscle movement

Rules of thumb

1. More moveable part moves towards the less moveable part.

2. The distal bone/part moves towards the proximal bone/part

IN GENERAL (for this class )

Origin:

Proximal attachment. (Where

the muscle starts)

Muscle contracts towards the origin◦ Less movable OR

stationary part

Insertion:

Distal attachment

More movable part

To figure Movement ask yourself…

1. What aspect/view am I looking at?

2. How many joints does it cross?

3. Where is the more movable or distal

attachment going to move?

Understanding Movement WS

Understanding Muscle movement con’t

Your turn to explore…

Using the skeletons…..

1. Put one end of rubber band on distal insertion (green dot). Hold on to rubber band.

2. Pull towards the proximal origin (red dot). Hold on to rubber band at the insertion.

3. Feel the body part spring into motion!

Muscular System Outline

Functions of Muscle

Aid in movement

Provide and maintain posture

Protect internal organs

Provide movement of blood, food and waste products throughout the body

Open and close body openings

Produces heat

3 Types of Muscle Tissue

1. Skeletal

2. Visceral

3. Cardiac

Visceral Muscle

Lines organs

Makes up walls of blood vessels

In the digestive system

Smooth – has no striations

Contracts when stimulated

Controlled by the autonomic nervous system

Cardiac Muscle

Only in the heart

Striated muscle

Involuntary control

Skeletal Muscle

Makes up 40 % of body weight

Increase in size and weight with exercise

Named according to:◦ Location

◦ Related bones

◦ Shape

◦ Action

◦ size

Looks striated under microscope

Tendons attach muscle to bone

3 parts of Skeletal muscle

1. Origin: attached to the less

movable part of bone – proximal

attachment

2. Insertion: attached to the more

movable part of the bone – distal

attachment

3. Body: middle part of the muscle

Fill in movement Definitions

Flexion = decreasing joint angle

Extension = increasing joint angle

Abduction = movement away from midline

Adduction = movement towards the midline

Pronation = turning palms down

Supination = turning palms up

Muscle stimulation

1. Electrically

2. Mechanically

3. Chemically

Vocabulary

Irritability or excitability: ability to respond to a stimulus

Contractility: ability to shorten

Extensibility: ability to stretch and lengthen

Elasticity: ability to recoil to its resting length

Units of Muscle Fibers

Sarcomere:

- Causes contraction

- Made up of actin and myosin
