Guide. An alanine aminotransferase (ALT) test measures the amount of this enzyme in the blood. ALT is found mainly in the liver, but also in smaller amounts in the kidneys, heart, muscles, and pancreas.ALT was formerly called serum glutamic pyruvic transaminase (SGPT).ow levels of ALT are normally found in the blood. But when the liver is damaged or diseased, it releases ALT into the bloodstream, which makes ALT levels go up.
The Biceps Brachii (commonly called the biceps) is a muscle located at the front of the upper arm and attaches your arm bone (humerus) to your shoulder.
The brachialis is a muscle located underneath the lower part of the biceps brachii. This muscle originates at the distal half of the anterior humerus, or arm bone, and inserts at the coronoid process and the tuberosity of the ulna, or outer forearm bone. The brachialis only has one function, and that is elbow flexion.
