The biceps or biceps brachii (Latin: musculus biceps brachii, "two-headed muscle of the arm") is a large muscle that lies on the front of the upper arm between the shoulder and the elbow. Both heads of the muscle arise on the scapula and join to form a single muscle belly which is attached to the upper forearm.
Lateral head. Medial head. The triceps, or triceps brachii (Latin for "three-headed muscle of the arm"), is a large muscle on the back of the upper limb of many vertebrates. It consists of 3 parts: the medial, lateral, and long head. [1] It is the muscle principally responsible for extension of the elbow joint (straightening of the arm).
The medial bicipital groove is seen on the surface anatomy of the upper arm. It is formed by the longitudinal hollow between the biceps and triceps muscles. The pulse of the brachial artery can be felt in the medial bicipital groove. [1] It should be distinguished from the bicipital groove or intertubercular sulcus, which is not a surface ...
Keep your shoulders back and down. Bend at your elbow to curl the dumbbells up toward your shoulders. Make sure to keep your elbows hugging the sides of your body. Lower both weights back down ...
An example of an antagonistic pair is the biceps and triceps; to contract, the triceps relaxes while the biceps contracts to lift the arm. "Reverse motions" need antagonistic pairs located in opposite sides of a joint or bone, including abductor-adductor pairs and flexor-extensor pairs.
The bicipital groove separates the greater tubercle from the lesser tubercle. [1] It is usually around 8 cm long and 1 cm wide in adults. [1] It lodges the long tendon of the biceps brachii muscle between the tendon of the pectoralis major muscle on the lateral lip and the tendon of the teres major muscle on the medial lip.
Triceps is the major extensor and brachialis and biceps the major flexors. Biceps is, however, the major supinator and while performing this action it ceases to be an effective flexor at the elbow. [8] Muscles of the arm [4] Posterior Triceps brachii, anconeus Anterior Brachialis, biceps brachii
Biceps muscle. The rotator cuff is a group of muscles and their tendons that act to stabilize the human shoulder and allow for its extensive range of motion. Of the seven scapulohumeral muscles, four make up the rotator cuff. The four muscles are: supraspinatus muscle. infraspinatus muscle. teres minor muscle.
