Final Lab

What are the actions of the Pec Minor?

Forward tilt, Abduction, Depression of the scapula

When all the fibers of the deltoids work together, what action do they produce?

Abduction

What primary muscle produces elbow extension?

Triceps

Where is the supraspinous process located?

Posterior, above the spine of the scapula

T or F: The coracoid process is flat and spans the distance between the sternum and the shoulder blade. It holds the arms at a distance so it doesn’t get in the way of the ribs.

False, the clavicle

Does the scapula assist in stabilization in the glenohumeral joint?

No, mobility and range of motion. Muscles stabilize.

T or F: The coracoid-clavicular ligament is located from the coracoid process to the bottom of the clavicle, where the rough coracoid process and trapezius line are located. It’s a strong and powerful ligament that keeps the clavicle and scapula together.

True

The are the actions of the middle fibers of the pec major?

Adduction, Horizontal Flexion, Inward Rotation

T or F: Contraction of all fibers of the deltoids abducts the arm, however when the anterior or posterior fibers contract separately, they can assist in adduction.

True

T or F: The glenohumeral ligament is found on the posterior side of the shoulder girdle and is a combination of these three sections: superior, middle, and inferior.

F, anterior

What is the difference between qualitative and quantitative analysis and research?

Quantitative: measurable vaiables (how many or to what extent)

Qualitative: Explores experiences, behaviors, and meanings (Why or how)

What action do you find the maximum stability in the glenohumeral joint?

Extension, Adduction, Inward rotation

Which muscle is synergistic to the latissimus dorsi?

Teres Major

Where is the most common site for shoulder bursitis?

Under the Anterior deltoid

When a dancer raises their arms above their head the bodies natural response is to let the shoulders rise. Why?

Glenohumeral rhythm: the muscles that raise the arm also elevate the scapula

Analysis for human movement yielded four distinct body patterns of movement. What are they?

Burst, sustained, ungulate, restrained

List the anterior articulating surfaces of each of the 12 ribs

1-2: head of sternum

3-7: sternum body

8-10: converge

11-12: float

What are the three anterior scapular muscles?

Pec Minor, subclavius, serratus anterior,

What are the three posterior scapular muscles?

Trapezius, Rhomboids, Levator Scapula

What joint connects the shoulder girdle to the axis skeleton?

Sternoclavicular Joint

What are the eight actions of the scapula?

Elevation, depression, adduction, abduction, upward rotation, downward rotation, forward tilt, and return from forward tilt.

What deviation from the spine is likely to occur if the curve of the clavicle are deep?

Kyphosis

Why do people have deeper clavicle curves than others?

Genetics, postural

What is movement behavior?

An analysis of watching qualitative behaviors that have been formed habitually from watching other people and past behaviors.

What does Fit call when we learn new things and we expand our movement potential but our central patterning stays the same?

Home base

Which joint is the ball and socket?

Glenohumeral Joint

What is the first step in identifying characteristics of movement behavioral patterns?

Observing

What re some symptoms/things you can see from pectoralis minor syndrome?

Winged scapular, forward shoulders, tingling, pinching, spasming, numbness in the fingers

List the muscle of the rotator cuff with the specific main action?

supraspinatus: abduction

infraspinatus: external rotation

teres minor: external rotation

subscapularis: internal rotation

What is the bony landmark on the posterior side of the scapula that leads into the acromia process?

The spine of the scapula

Name the shoulder joint movement that tends to most readily aggravate shoulder impingement?

Abduction

What functional muscle groups should we strengthen to fix rolled shoulders?

Scapular Adductors

What action does the shoulder have on the scapula in:

Shoulder external rotation:

Shoulder Abduction:

Shoulder Flexion:

adduction

up rotation, elevation

upward rotation, abduction

What is the function of the SITS force couple?

Counters the upward pull of the deltoids

Name the bone that crosses medially in the lower forearm in pronation

Radius

What is the name of the muscle that produces elbow flexion and radioular supination

Bicep brachii

Define glenohumeral rhythm

The shoulder and scapular move together as one to prevent injury.

what is it called when there is constant misfiring from one primary misalignment?

chain reaction

What three things do you need to prepare for optimal peak performance?

Physical, mental, phycological

That are the two joints that make up the shoulder girdle?

sternoclavicular and acromioclavicular

What rea the two primary shoulder external rotators?

teres minor and infraspinatus

what are the two main shoulder abductors?

deltoids and supraspinatus
