false
The supraspinatus, infraspinatus, teres minor and the CORACOBRACHIALIS are the rotator cuff muscles.
false
The tendons of insertion of the EXTENSOR DIGITORUM COMMUNIS corss the writs through the carpal tunnel.
false
The tendons of insertion of the flexor digitorum muscles are held close to the wrist by the POSTERIOR CARPAL RETINACULUM.
false
The trapezius muscle in humans ORIGINATES on the acromian process, spine of scapula, and clavicle.
false
The trapezius muscle, in the human, inserts on the ULNA.
false
A muscle that flexes the elbow and supinates the hand is the BICEPS BRACHII.
true
An APONEUROSIS is a broad, flat, tendinous sheet.
true
An example of a MULTIPENNATE muscles are the deltoid and the serratus anetrior.
true
Between the skin and the muscle mass is a layer of connective tissue called the SUPERFICIAL fascia.
true
Major muscles attaching to the vetetral border of the scapula include the SERRATUS ANTERIOR AND RHOMBOID (RHOMBOIDEUS) MAJOR.
true
Many of the EXTENSOR muscles originate on the lateral epicondyle of the humerus.
true
Muscles originating on the medial epicondyle of the humerus normally tend to be FLEXORS of the wrist, hand, or fingers.
true
The GLUTEUS MAXIMUS muscle adducts the thigh at the hip.
true
The PALMARIS LONGUS muscle functions to tense the palmar fascia (palmar aponeurosis) of the hand and also contributes to the flexion of the wrist.
true
The RETINACULUM is a thickening of fascia that holds strucutres in place.
true
The SHORT HEAD of the biceps femoris originates on the linea aspera of the femur.
true
The TIBIALIS ANTERIOR muscle inverts the foot.
true
The action of flexion of the wrist by the flexor carpi ulnaris muscle is an example of a CLASS 3 LEVER.
true
The antagonist of the brachialis muscle is the TRICEPS BRACHII.
true
The conspicous sheath of dense fibrous connective tissue covering the muscle mass of the forearm is the ANTEBRACHIAL FASCIA.
true
The following muscles aid in the flexion of the arm at the elbow: BICEPS BRACHII, BRACHIALIS, AND BRACHIORADIALIS.
true
The proximal part of the upper limb is called the arm or BRACHIUM.
true

true
The system of dense fibrous connective tissue that covers the muscle mass of the thigh is the FASCIA LATA.
true
The thick sheet (strip) of consicuously dense fibrous connective tissue that runs along the lateral side of the thigh is claled the ILIOTIBIAL BAND.
true
The triceps brachii has its insertion on the olecranon process of the ulna.
true
These following muscles aid in the movement of scapular UPWARD rotation: trapezius and serratus anterior.
true
Three muscles in the cat represent the trapezius muscle of humans.
true
