Answer 10

Pectoralis major, pectoralis minor

Question 11

Function of pectorals

Answer 11

Shoulder Flexion: reaching up or forward.
Shoulder Adduction: doing a hugging motion.
Internal Rotation of the Arm: Rotating your arm inward toward your body.
Needed pushing actions, like when you push something away or perform exercises like push-ups or bench presses.

Question 12

What is by the scapular?- what does it do

Answer 12

Subscapularis- Internal Rotation of the Arm: It rotates the arm inward, toward the body
Stabilizing the Shoulder Joint: helps hold the head of the humerus (upper arm bone) in the shoulder socket, maintaining shoulder stability during movements.
essential for movements that involve pushing or rotating the arm inward.

Question 13

2 arm muscles

Answer 13

Biceps brachii, tricep brachii

Question 14

What does teres minor do

Answer 14

External Rotation of the Arm: It helps rotate the arm outward, away from the body.
Stabilizing the Shoulder Joint: helps keep the head of the humerus (upper arm bone) securely in the shoulder socket during arm movements.
important for shoulder stability and movements like reaching backward or rotating the arm outward.

Question 15

What does teres major do

Answer 15

Shoulder Extension: Moving the arm backward, similar to pulling movements.
Shoulder Adduction: Bringing the arm down toward the side of the body.
Internal Rotation of the Shoulder: Rotating the arm inward toward the body.
The teres major works closely with the latissimus dorsi to help with pulling and stabilizing movements of the arm.

Question 16

Which is the the bottom teres

Answer 16

Major at bottom, minor at top

Question 17

What muscles make movement at wrist

Answer 17

Wrist flexor (side of palm up), wrist extensors (back of arm)

Question 18

What does the latissimus dorsi do

Answer 18

Shoulder Extension: Moving your arm backward, (e.g., rowing or pulling up).
Shoulder Adduction: Bringing your arm down towards your body from the side
Shoulder Internal Rotation: Rotating your arm inward toward the body, like turning your palm toward your body while keeping your arm straight.
For pulling movements, such as climbing or swimming.

Question 19

What do the rhomboids do + where located?

Answer 19

Between shoulder blades. Scapular Retraction: Pulling the shoulder blades (scapulae) together towards the spine, like when you squeeze your shoulder blades together.
Scapular Elevation: Lifting the shoulder blades slightly upward.
Scapular Downward Rotation: Rotating the shoulder blades downward, such as when lowering your arms from an overhead position.

Question 20

Function + whereabouts of infraspinatus

Answer 20

Back of shoulder blade. External Rotation of the Arm: It helps rotate the arm outward, away from the body, similar to the teres minor.
Stabilizing the Shoulder Joint: helps hold the head of the humerus (upper arm bone) securely in the shoulder socket, providing stability during arm movements.
This muscle is especially important for movements like throwing, reaching behind, or rotating the arm outward.

Question 21

Function of trapezius

Answer 21

Scapular Elevation: Lifting the shoulder blades, like when you shrug your shoulders.
Scapular Retraction: Pulling the shoulder blades together toward the spine.
Scapular Depression: Lowering the shoulder blades, like when you push your shoulders down.
Scapular Upward Rotation: Rotating the shoulder blades upward, which helps when you lift your arms above your head.
The trapezius also helps stabilize the neck and shoulders and supports movements like raising the arms, pulling, and lifting.

Question 22

Function of deltoids

Answer 22

Shoulder Flexion: Lifts the arm forward, like when reaching out in front of you.
Internal Rotation: Rotates the arm inward toward the body.
Shoulder Abduction: Lifts the arm out to the side, as in raising your arm up from the side.
Shoulder Extension: Moves the arm backward, like when pulling something behind you.
External Rotation: Rotates the arm outward, away from the body.

Question 23

Whereabouts + function of sternocleidomastoid

Answer 23

Front of neck. Head Flexion: bringing your chin toward your chest.
Head Rotation: Turning the head to the opposite side
Lateral Flexion: bringing the ear closer to the shoulder on the same side.
This muscle is crucial for movements and stabilization of the head and neck, and it plays a role in posture and head positioning.
