Abstract. Hyperbranched polymers are polymers based on A x B-monomers, ie, monomers having one B-functionality and two or more A-groups resulting in polymers with a potential branching point in each repeat unit.
Source(s): 30 years in sports medicine and clinical nutrition. The biceps brachii is a antagonist of the triceps brachii. If the triceps brachii will contract, the biceps brachii will stretch and vice versa. Pushups. I do about 500 per day (200 AM, 300 PM) and my arms aren't huge, but they're toned pretty well, I guess.
The biceps brachii splits in two heads, the long and short head, as it runs across the anterior of the upper arm. The triceps brachii splits into three heads (long, lateral and medial) as it runs across the posterior of the upper arm. The biceps bend your elbows and rotate your hands. They are the prime movers in elbow flexion and wrist supination.
