EMG and Muscle Micro-anatomy

Motor Unit

the unit of skeletal muscle control, single lower motor neuron

Isometric Muscle Contraction

static exercising, muscles generate force WITHOUT moving any joint or length of joint

Isotonic Muscle Contraction-

muscle tension remains constant when the muscle length changes in order to create movement 

Agonist Muscle

muscle that produces a certain movement at a joint through shortening and contracting the muscle

Antagonist Muscle

 muscle that opposes the action of another muscle through relaxing and lengthening the muscle

EMG

an electromyography test determines muscle and nerve health by measuring electrical activity throughout the body. It is usually used to diagnose carpal tunnel, nerve compression, or muscular dystrophy

Muscle Fatigue

reversible decline in your muscles performance. This is often caused by over working muscles, going to the gym too much, and intense exercise that your muscles can not handle   

Muscular Contraction

tension is generated in muscle fibers by the sliding filament mechanism that involves actin and myosin proteins which produce muscle contraction and cellular movement 

WHOLE SARCOMERE:H zone, A band, I band, Z line, M line

Actin

Thin filament

Myosin

Thick filament

Muscle Micro Anatomy

Myofibril, Transverse Tubules, Triad, Sarcoplasmic Reticulum, Terminal Cisternae

Striations and Nuclei
