Muscles have their origins (also known as heads) and insertions. Those are places where the muscles are anchored.
A word biceps is made of two Latin words: bi - two and ceps - head. So, biceps is two-headed muscles. It has two origins: coracoid process of the scapula and supraglenoid tubercle.
Similarly, a word triceps is made of three Latin words: tri - three and ceps - head. So, triceps is three-headed muscles. It has three origins: infraglenoid tubercle of scapula, above the radial sulcus, and below the radial sulcus.
