Proximal to the elbow and attach to the ulna and radius.
They are bound closely and firmly by ligaments and form two rows of four carpals each.

The pisiform is a small, pea-shaped carpal bone located in the wrist.
It opposes the little finger.
Radiocarpal joint and midcarpal joint.
Clavipectoral region.
By the coordinated action of several muscles; some muscles in the group contract while others relax.
Synergist muscles contract at the same time as the prime movers, facilitating prime mover actions to produce a more efficient movement.
The subscapularis, teres major, and latissimus dorsi muscles.
The superior border of the clavicle is the upper edge of the clavicle bone.
Serratus anterior and pectoralis minor.
It opposes the thumb.
Carpometacarpal joint, metacarpophalangeal joint, and interphalangeal joints.

Scaphoid, lunate, triquetrum, and pisiform.
The coracoid process serves as an attachment point for muscles and ligaments.
Brachialis, biceps brachii, and brachioradialis.
Flexing the metacarpophalangeal joints and extending the interphalangeal joints.
Cubital region.
Flexion, adduction, and medial rotation of the humerus.
Anteriorly (chest) or posteriorly (back and neck).
Muscles that, when contracting, directly oppose prime movers. They relax while the prime mover (agonist) is contracting to produce movement, providing precision and control during contraction of prime movers.
The skin and fascia of the armpit.
Carpal bones.
The heads of the metacarpals are located at the distal ends of the metacarpal bones, forming the knuckles.
Adductor pollicis.
Deltoid, claviculopectoral triangle, pectoral, scapular, axillary, anterior arm, posterior arm, cubital, posterior elbow, anterior forearm, posterior forearm, anterior wrist, posterior wrist, palm/palmar, dorsum of hand, digits (fingers including thumb).
Humerus
The thumb metacarpal.
Radius and ulna.
The olecranon is located at the proximal end of the ulna, forming the point of the elbow.
10-15 degrees.
Flexor digiti minimi.
Radius and ulna.
Palm/hand, Dorsum of hand, Digits (including thumb).
Levator scapulae.
Any 'mover' muscle that directly performs a movement, including the prime mover.
The acromion process.
Eight small bones.
The intertubercular sulcus of the humerus.
The acromion is a bony process on the scapula (shoulder blade).
Descending (superior) trapezius and serratus anterior (inferior part).
Clavicle and scapula.
Deltoid region.
It attaches to the clavicle and the first rib.
On the little finger side of the forearm
The cervico-axillary canal.
Ulna.
Descending (superior) trapezius and levator scapulae.
Greater than 15 degrees.
Median nerve.
Carpus, metacarpus, and phalanges.
Scapular region.
On the anterior or posterior surfaces of the forearm.
Hamate, capitate, trapezoid, and trapezium.
Trapezium, trapezoid, capitate, and hamate.
The lateral epicondyle is located on the outer side of the distal humerus.
Triceps brachii and anconeus.
Humerus.
Anterior forearm and Posterior forearm.
Pectoralis minor.
A muscle that directly performs a specific movement.
The shoulder is a synovial joint allowing extensive movement in every plane of motion.
Fixator muscles are joint stabilizers and a type of synergist.
The serratus anterior muscle and the thoracic wall (ribs 1-4 and intercostal muscles).
The acromioclavicular joint is located between the acromion of the scapula and the clavicle.
Middle (transverse) trapezius and rhomboids.
Abductor pollicis brevis (AB).
Deltoid, Clavipectoral, Pectoral, Axillary, Scapular, Arm, Cubital, Anterior forearm, Posterior forearm, Wrist, Palm/hand, Dorsum of hand, Digits (including thumb).
It helps in the movement of the scapula and is involved in the elevation of the ribs.
Flexor pollicis longus.
Elbow joint.
Clavicular head, sternocostal head, and abdominal part.
Axillary region.
Pectoralis minor.
It stabilizes and moves the scapula.
