Name and describe 5 muscles that are commonly torn or sprained and the mechanism that often leads to these injuries.

What are the origin, insertion, and nerve supply for Sartorius muscle? origin: insertion: nerve supply:

Put a check mark next to the muscles that are skeletal muscles. Hint: Consider location and whether muscle contraction is voluntary or involuntary. ______________________ 7. Arrector pili ______________________ 8. Tongue ______________________ 9. Muscle in gallbladder ______________________ 10. Muscles that control movement of the eyeball

What are the origin, insertion, and nerve supply for Vastus lateralis muscle? origin: insertion: nerve supply:

6. 7. Identify the muscles on the list below using images of drawings, models, or cadavers. Be able to give the action for each muscle on the list below, and the skeletal attachments for only the muscles that are indicated by an asterisk. When given an action, be able to determine which skeletal attachment point is the origin and which is the insertion. Muscle Identification, Actions, and Skeletal Attachments Identify the muscles in this list on an image of a drawing, model, or cadaver. Be able to give the action for ALL the muscles in this list. For muscles denoted with an *, know the skeletal attachments. Head & Neck Orbicularis oculi Orbicularis oris Zygomaticus major Buccinator Temporalis Chest and Back Pectoralis major* Latissimus dorsi Serratus anterior Levator scapulae Deltoid* Trapezius* Rotator Cuff Group Supraspinatus* Infraspinatus* Subscapularis* Teres minor* Upper Arm Biceps brachii* Brachialis Triceps brachii* Lower Arm Pronator teres Brachioradialis Flexor carpi radialis…

2B. Define a twitch. Discuss the phases of a twitch when graphed. List the events that occur at each.

What are the origin, insertion, and nerve supply for Tensor fasciae latae muscle? origin: insertion: nerve supply:

1. Provide all muscles involved in accomplishing the movement. 2. Provide the action of each of the muscles involved • Swallowing • Chewing • Raising the eyebrows • Furrowing the brows (bringing the eyebrows together) • Flaring or widening the nostrils • Smiling • Frowning • Pouting • Winking • Kissing or puckering • Lip snarl • Sticking your tongue out • Rolling your eyes • Crossing your eyes (looking down, toward the nose) • Popping the ears

Describe a physical movement such as sitting, throwing, kicking, stepping up, lifting a coffee cup, etc. Describe the specific muscles involved in this movement using the correct anatomical names. State the type of movement (flexion, extension, and rotation for example) for each muscle that you identify as involved in the movement.

During a Physical Education class, you ask your students to perform a standing vertical jump. Identify the type of muscle contraction involved in the jump and describe the movement patterns of the concentric and eccentric phases. Outline the agonists, antagonists and synergist muscles, which contribute to maximum jump height. Identify the major lower body joints and joint movements, which contribute to the concentric phase of the jump.
