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.
It is the groove where the long head of biceps tendon runs between the greater and lesser tubercles below the humeral head before inserting into the superior glenoid rim. The lateral bicipital groove is seen on the lateral aspect of the upper arm, and is formed by the same anatomical structures as the medial groove.
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 three 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 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.
Other nerves passing through give no supply to the arm. These include: The median nerve, nerve origin C5-T1, which is a branch of the lateral and medial cords of the brachial plexus. This nerve continues in the arm, travelling in a plane between the biceps and triceps muscles.
