NASM-CPT MUSCULAR SYSTEM EXAM 2025/2026
WITH 100% ACCURATE ANSWERS
1. What muscle acts as a synergist when performing an overhead elbow
extension exercise?
Triceps brachii
Biceps Brachii
Anconeus
2. Characteristics of type II muscle fibers include all of the following EXCEPT:
the use of anaerobic respiration (glycolysis) to produce fast
contractions.
undergo hypertrophy
the use of aerobic respiration for primary ATP production.
the inability to undertake contractions necessary for endurance.
3. What term describes the process by which the nervous system stimulates
muscle contraction?
Synaptic transmission
Motor unit recruitment
Muscle hypertrophy
Neural activation
4. Describe how neurotransmitters contribute to the process of muscle
,contraction.
Neurotransmitters facilitate oxygen transport to muscle fibers.
, Neurotransmitters store energy for muscle contraction.
Neurotransmitters transmit electrical impulses from the nerve to
the muscle, initiating contraction.
Neurotransmitters regulate blood flow to the muscles.
5. Describe the significance of the perimysium in relation to muscle function.
The perimysium stores energy for muscle contraction.
The perimysium connects muscles to bones, allowing for movement.
The perimysium is responsible for the contraction of muscle fibers.
The perimysium provides structural support and organization to
muscle fibers within fascicles, facilitating coordinated contraction.
6. What is the primary function of stabilizer muscles in physical activities?
Supporting the prime mover and synergist
Generating force for movement
Opposing the action of antagonists
Facilitating muscle relaxation
7. During a squat, if the transversus abdominis is weak, what might be the
potential impact on the squat performance?
Improved power output and efficiency
Increased muscle hypertrophy in the legs
Enhanced flexibility and range of motion
Decreased stability and increased risk of injury
