Muscle flashcards!
1. Cut out flashcards 2. Hole punch 3. Divide into upper and lower 4. Combine lower muscles onto your skeletal flashcard ring 5. Grab colored pencil We will go through the upper muscle 2 times 1. First time just to label 2. Second time to put in movements Please:
Label each card: anterior/posterior/medial/lateral as it comes up on the screen. There will be repeats but at different surfaces
trapezius Levator scapulae rhomboids
MAKE SURE YOU HAVE THE CORRECT LATERAL FLASHCARD, THERE ARE DIFFERENT ONES sternocleidomastoid Pectoralis minor Serratus anterior
This one trapezius Posterior deltoid Triceps brachii
MAKE SURE YOU HAVE THE CORRECT LATERAL FLASHCARD, THERE ARE DIFFERENT ONES Latissimus dorsi Posterior deltoid Middle deltoid
MAKE SURE YOU HAVE THE CORRECT LATERAL FLASHCARD, THERE ARE DIFFERENT ONES Anterior deltoid Pectoralis major Latissimus dorsi
Anterior deltoid Pectoralis major Biceps brachii
Rectus abdominis/trunk flexion Transverse abdominis/pulls abdominal wall inward
External obliques/lumbar flexion Internal obliques/ lumbar flexion
New muscles! Supraspinatus/ arm abduction Teres minor/arm external rotation Infraspinatus/arm external rotation Subscapularis/ arm internal rotation
Biceps brachii brachialis brachioradialis
Palmaris longus Flexor digitorum superficialis
Review time! Independently THEN with buddy
Example: Trapezius: neck (put body part/joint) extension/shoulder elevation References: Your brain! squish your hand Muscle memory We will correct Go back through and put movement

Understanding Muscle movement
1. More moveable part moves towards the less moveable part. 2. The distal bone/part moves towards the proximal bone/part Rules of thumb
Origin: Proximal attachment. (Where the muscle starts) Muscle contracts towards the origin Less movable OR stationary part Insertion: Distal attachment More movable part IN GENERAL (for this class )
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
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! Your turn to explore

Muscular System Outline
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 Functions of Muscle
1. Skeletal 2. Visceral 3. Cardiac 3 Types of Muscle Tissue
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 Visceral Muscle
Only in the heart Striated muscle Involuntary control Cardiac 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 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 3 parts of Skeletal muscle
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 Fill in movement Definitions
1. Electrically 2. Mechanically 3. Chemically Muscle stimulation
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 Vocabulary
