●● Skeletal (Striated) Muscle
Answer: Voluntary muscle attached to bones that controls body
movement.
●● Cardiac Muscle
Answer: Involuntary muscle found only in the heart that contracts
rhythmically.
●● Muscle Fiber
Answer: An individual muscle cell.
●● Neuromuscular Junction
Answer: The synapse between a motor neuron axon and a muscle fiber.
●● Acetylcholine (ACh) in Skeletal Muscle
Answer: The neurotransmitter released by motor neurons to excite
muscle contraction.
●● Flexor Muscle
, Answer: A muscle that bends a limb, such as the biceps.
●● Extensor Muscle
Answer: A muscle that straightens a limb, such as the triceps.
●● Proprioceptors
Answer: Sensory receptors that detect body position and movement.
●● Muscle Spindles
Answer: Proprioceptors parallel to the muscle that detect muscle stretch.
●● Golgi Tendon Organs
Answer: Proprioceptors that detect tension in tendons and inhibit further
contractions.
●● Motor Neuron
Answer: A neuron that controls muscle contraction.
●● Motor Unit
Answer: One motor neuron and all the muscle fibers it innervates.
●● Small Motor Units
