Long head- Supraglenoid tubercle of scapula
Tuberosity of the radius and aponeurosis of biceps brachii
Flexes elbow, supinates forearm, flexes shoulder joint
Triceps Brachii
Long head- Infraglenoid tubercle of scapula
Lateral head- Posterior surface of proximal half of humerus
Medial head- Posterior surface of distal half of humerus
All heads- olecranon process of ulna
Long head- Extends and adducts the shoulder
All heads- Extend the forearm (elbow)
Subclavius

What kind of muscle not responsible for flexion or extension of the arm?
Which of these muscles is not responsible for flexion or extension of the arm?
What muscles act in plantar flexion?
popliteus is not involved in plantarflexion...its involved in leg flexion
What muscles are involved in horizontal flexion?
The muscles that horizontally flex the shoulder are the Pectoralis Major and the coracobrachialis.
What three muscles are involved in flexion of the elbow joint?
biceps brachii,corahobrachialis,biseps
What muscles are used during waving?
Several muscles are used. Biceps brachii for elbow flexion, triceps brachii for elbow extension. Trapezius to raise arm. Deltoid abducts the arm. The pectoralis major allows internal rotation, adduction, and flexion of the arm. The pronator quadratus, pronator teres and supinator all arm forearm muscles that move the wrist. The brachioradialis, brachialis and aconeus are also used.
What is flexion?
to pull the muscles together EX.take your arm arm and put you hand aganst your shoulder you are flexing
Where does flexion of the arm occur?
at the elbow. "Flexion of the arm" just means to bend it.
Where is your biceps?
Biceps brachii muscle, is a muscle located on the inside of the upper arm Biceps femoris muscle, is one of the hamstring muscles at the back of each thigh
What is the function for the Gastonemius muscles?
plantar flexion and knee flexion
What is the function of the brachii muscle?
The coracobrachialis muscle is involved with in the flexion and the adduction of the shoulder. That is to say, raising the arm and bringing the arm across the chest, respectively.
What are the muscles in the upper arm that cause it to straighten?
Tricep brachii is responsible for extension (straightening) of the arm at the elbow. There are 3 heads of the Tricep; the long, lateral and medial heads. The Tricep is an antagonist of the bicep and brachialis muscles of the upper arm, which both assist in flexion at the elbow joint.
What muscles are agonists in plantar flexion?
The opposite of plantar flexion is dorsiflexion. Plantar flexion means to increase the angle at the ankle, as in tip-toeing. The muscles involved in dorsiflexion (picking up the toes) are:tibialis anterior muscleextensor hallucis longus muscleextensor digitorum longus muscleperoneus tertius
