Abductors / AdductorsQuestion:Muscle or muscles that answers the question:Prime mover of arm abduction is the deltoid; what is an adductor of the arm?If the gracilis adducts the thigh, name a muscle that would abduct the thigh.

The sketch below shows FLEXION of the THIGH at the HIP joint. Which of the following muscles are responsible for this action (multiple correct answers)? ma ✔Gluteus maximus ✔lliopsoas ✓Gracilis ✔Gluteus medius ✔Tensor fascia latae Adductor magnus Adductor longus ✔Sartorius HIP thigh KNEE leg

* These muscles (and subscapularis) form the rotator cuff which is a critical stabilizing element for the glenohumeral joint (shoulder joint). Thus, one action for each of these muscles is to stabilize the shoulder joint. Examine the rotator cuff muscles in the cadaver and see if you can determine where the tendons incompletely surround the head of the humerus. What clinical significance does this have?

describe scapulohumeral movement, or synergy, that takes place with the shoulder joint and girdle. What muscles are acting to create these motions? What could happen if this synergy did not occur?

Flexors / ExtensorsQuestion:Muscle or muscles that answers the question:Contracting both heads of this muscle (deep to the platysma) causes flexion of the head.Contraction this muscle would cause the vertebral column to flex forward—used to do “sit-ups”.As a group, these muscles extend (straighten the angle of) the knee. What is this group?As a group, these mucles flex the knee (decrease the angle between the thigh and lower leg). What is this group?

During elbow flexion which muscles would NOT act to cause this action? Group of answer choices Biceps brachii All of these muscles would produce flexion at the elbow Flexor carpi radialis Brachialis

Describe 3 muscles that move the femur (thigh)

After throwing a baseball pitch, which muscles of the glenohumeral joint work to slow the motion of the shoulder? Consider one of flexor, internal rotator, external rotator or adductor.

Which movement at the ankle is controlled by the most muscles, plantar or dorsiflexion? List at least two functional movements that would be important to have adequate dorsiflexion.
