NASM-CPT (7TH EDITION) CHAPTER 5 LATEST
JUPDATEC 2025/2026 WITH 100% ACCURATE
QUESTIONS AND ANSWERS
Excitation Contraction Coupling-CORRECT ANSWERThe physiological process of converting an electrical
stimulus to a muscle contraction.
Power Stroke-CORRECT ANSWERThe myosin heads bind to actin and pull them toward the sarcomere
center, which slides the filaments past each other, shortening the muscle.
Adenosine Triphosphate (ATP)-CORRECT ANSWERA high-energy molecule that serves as the main form
of energy in the human body; known as the energy currency of the body.
Resting Length-CORRECT ANSWERThe length of a muscle when it is not actively contracting or being
stretched.
Type 1 Muscle Fibers (Slow Twitch)-CORRECT ANSWERMuscle fibers that are small in size, generate
lower amounts of force, and are more resistant to fatigue.
Type 2 Muscle Fibers (Fast Twitch)-CORRECT ANSWERMuscle fibers that are larger in size, generate
higher amounts of force, and are faster to fatigue.
Human Movement System (HMS)-CORRECT ANSWERThe collective components and structures that
work together to move the body: muscular, skeletal, and nervous systems.
Kinetic Chain-CORRECT ANSWERA concept that describes the human body as a chain of interdependent
links that work together to perform movement.
Nervous System-CORRECT ANSWERA network of specialized cells called neurons that transmit and
coordinate signals, providing a communication network within the human body.
, Neuron-CORRECT ANSWERSpecialized cell that is the functional unit of the nervous system.
Nucleus-CORRECT ANSWERCellular structure or organelle that contains the majority of the cell's genetic
material in the form of chromosomes.
Organelles-CORRECT ANSWERTiny cellular structures that perform specific functions within a cell.
Examples include nuclei, mitochondria, lysosomes, ribosomes, and the endoplasmic reticulum.
Mitochondria-CORRECT ANSWERThe parts of the cell that use nutrients to create energy for the cell;
commonly known as the powerhouses of the cell.
Effector Sites-CORRECT ANSWERA part of the body, such as a muscle or organ, that receives a signal
from a neuron to produce a physiological response.
Electrolytes-CORRECT ANSWERMinerals that have an electrical charge to help transmit nerve impulses
throughout the body, such as sodium, potassium, and magnesium.
Central Nervous System (CNS)-CORRECT ANSWERA division of the nervous system that includes the
brain and spinal cord.
Peripheral Nervous System (PNS)-CORRECT ANSWERNerves that connect the rest of the body to the
central nervous system.
Afferent Pathway-CORRECT ANSWERSensory pathway that relays information to the central nervous
system.
Efferent Pathway-CORRECT ANSWERA motor pathway that relays information from the central nervous
system to the rest of the body.
Interneurons-CORRECT ANSWERNeurons located within the spinal cord and brain that transmit impulses
between afferent and efferent neurons.
