Gross Anatomy of the Muscular System Muscle actions are often described as a departure of the from the anatomical position of the body. In performing the next exercise, you will understand how muscles act to affect motion. Materials *Participant (can be yourself) *Heavy Object (approximately 5 pounds) *You must provide Procedure 1. Begin by examining

Muscle Fatigue Muscle contractions are essential for muscles to function properly. The inability of a muscle to maintain tension is muscle fatigue. Failure to contract may occur because of the accumulation of lactic acid, a lack of ATP, or decreased blood flow. In this exercise, you will investigate the correlation between repeated movements and muscle

The Neuromuscular Junction Each skeletal muscle is connected to the nervous system be motor end units. When the neurotransmitter acetylcholine is release at this site, the muscle fiber depolarizes. Calcium ions are released from stores in the sarcoplasmic reticulum. The presence of Ca2+ triggers the ratcheting of actin and myosin filaments and the contraction of
