anatomy Flashcards
simple movement
movement that uses only one joint to target only one muscle
compound movement
movement that uses more than one joint and targets more than one muscle/group
prime mover of chest
pectorals, made up of pectoralis major and pectoralis minor (under pectoralis major)
primary function of pectorals
adduct, flex and medially rotate the arm at the shoulder joint
pectoralis major main function and exercise
adduction and flexion of the humerus
chest press
pectoralis minor
originates at the 3rd, 4th, 5th ribs… superior surface/medial portion of the coracoid process of the scapula
pectoralis minor main function and exercise
depresses and protracts the scapula
dips
deltoids
shoulder muscles
three parts… front (anterior), middle (lateral) and back (posterior)
prime movers for arm abduction
deltoids
what muscles do the shoulders work with/help
They work with the
chest and back muscles for abduction and adduction
of the humerus, and for extension and flexion of the
shoulder joint at the humerus. They also, with help from the chest muscles, work for overhead pushing
movements.
main function of the deltoids
abduction of the humerus; medial rotation of the humerus
main function of posterior deltoid
horizontal abduction; extension, abduction and external rotation of the shoulder joint at the humerus
exercise for deltoids
lateral dumbbell raises
rotator cuff
beneath the deltoids
group of four muscles that originate from the scapula and connect to the head of the humerus
functions to support the arm, keep head of the humerus firmly in the shoulder socket during movement
four muscles of the rotator cuff and function
Supraspinatus: abducts the arm
Infraspinatus: externally rotates the arm
Teres Minor: externally rotates the arm
Subscapularis: internally rotates the humerus
biceps
biceps brachii, made up of two bundles of muscle that originate from the scapula, stretching downward to form one single muscle attaching/inserting to the medial part of the forearm
what are the biceps the prime mover of
to supinate the forearm and flex the elbow
parts of the biceps
long head
short head
** cannot isolate biceps from the brachialis **
exercises to work the bicep long head and short head
since you cannot isolate one from the other
Barbell Curls Bent Rows Chin-Ups Close-Grip Pulldowns Concentration Curls Curls Hammer Curls Lat Pulldowns Low Pulley Curls One-Arm Dumbell Rows Reverse Chin-Ups T-Bar Rows
ways to target more of the short head of the bicep
Curl with your elbows in front of your body (upper arm held up parallel with the floor).
Curl with a wide grip.
Curl with a supinated grip (palm held upward and outward.
Curl with your arms held laterally toward your body.
ways to target more of the long head of the bicep
Bring your hands closer together (close grip).
Use a neutral grip, aka hammer grip.
Curling with your elbows at your side.
Curling with your elbows back behind you.
main function of biceps
elbow flexion
main function and exercise of triceps
elbow extension
tricep extensions
triceps
made up of three bundles of muscle each of different origins, joining at the proximal end of the ulna at the elbow
The long head’s origin is on the scapula, or shoulder blade. The origins of the medial and lateral heads are on the humerus.
muscles of the triceps
medial
lateral
long head
how to emphasize different tricep heads
To place more emphasis on the long head, use movements with arms extended or above the head. To place more emphasis on the medial and lateral heads, use movements with the arms down and close-grip pressing movements.
OVERHEAD EXTENSIONS STRESS THE TRICEPS LONG HEAD TO A GREATER DEGREE THAN THE OTHER TWO HEADS.
tricep exercises
Bench Dips Bench Press Dumbbell Press Dumbbell Pullovers Dumbbell Triceps Extension Incline Dumbell Press Incline Press One-Arm Dumbbell Triceps Extension Overhead Triceps Extension Parallel Bar Dips Push-Ups Pushdowns Triceps Kickbacks
forearms
region between the elbow and the wrist that is comprised of many muscles, allowing movement at the fingers, elbow and wrist.
anterior forearm muscles = flexors
posterior arm muscles = extensors
main function/exercises for forearms
MAIN FUNCTION: Flexion, extension, radial and ulnar
deviation of wrist
EXERCISE FOR THIS MUSCLE: Wrist curls and reverse wrist curls
target forearm extensors
reverse wrist curls
reverse curls
target forearm flexors
