The Muscular System
These muscles are attached to bone.
Skeletal Muscle
A specialized plasma membrane.
Sarcolemma
Ability to shorten when an adequate stimulus is received.
Contractility
Palms down.
Pronation
The immediate source of energy for muscle contraction
ATP
The speed of contraction of these muscles are very slow.
Smooth Muscle
Contractile unit of a muscle fiber.
Sarcomere
Ability to recoil and resume resting length after stretching
Elasticity
Bending your elbow and reducing the joint angle.
Flexion
This pathway requires oxygen use.
Aerobic Pathway
This tissue is on the outside of the epimysium.
Fascia
A mysin filament.
Thick Filament
One motor neuron and all the skeletal muscle cells stimulated by that neuron.
Motor Unit
Turning your head left and right.
Rotation
This reaction that breaks down glucose without oxygen
Anaerobic Glycolysis
This muscle has striations, a single nucleus and is involuntary.
Cardiac
This stores and releases calcium along with surrounding a myofibril.
Sarcoplasmic Reticulum
The gap between nerve and muscle.
Synaptic Cleft
Moving a limb toward the midline.
Adduction
Accumulation of lactic acid can create this.
Muscle Soreness
A sheetlike structure that attaches muscles indirectly to bones, cartilage or connective tissue coverings.
Aponeuroses
Composed of the contractile protein actin.
Thin Filament
This breaks down acetylcholine into acetic acid and choline.
Acetylcholinesterase (AChE)
Touching your thumb to each of your fingers on the same hand.
Opposition
This is the FASTEST way to create energy.
Direct phosphorylation
