Place the following muscle cell structures in sequential order (first to last) during muscle cell activation:
A:) Ryanodine Receptor, Dihydropyridine Receptor, Transverse Tubule, Sarcolemma
B:) Sarcolemma, Transverse Tubule, Dihydropyridine Receptor, Ryanodine Receptor
C:) Sarcolemma, Transverse Tubule, Ryanodine Receptor, Dihydropyridine Receptor
D:) Transverse Tubule, Ryanodine Receptor, Dihydropyridine Receptor, Sarcolemma
Answer:
Sarcolemma, Transverse Tubule, Dihydropyridine Receptor, Ryanodine Receptor. The action potential travels first across the sarcolemma. Transverse tubules are parts of the sarcolemma that travel deep into the muscle cell to propagate the action potential to the inner portions of the cell. If you’re having trouble remembering which receptor comes first in the process
What is the relative involvement of slow-twitch muscle fibers during a 100 meter sprint?
A:) Low involvement
B:) High involvement
Answer:
Low involvement. Type I muscle fibers are “slow-twitch” and have higher resistance to fatigue due to higher capacity for aerobic energy supply. Type II muscle fibers are “fast-twitch” and have higher capacity for rapid force generation, and lower resistance to fatigue due to greater anaerobic energy supply. As the 100 meter sprint is a high-intensity, short-duration activity, there will be higher relative involvement of Type II muscle fibers which use anaerobic energy systems.
Which muscle fiber type has the least myoglobin content?
A:) Type I
B:) Type IIa
C:) Type IIx
Answer:
Type IIx. Type I muscle fibers are “slow-twitch” and have higher resistance to fatigue due to higher capacity for aerobic energy supply. Type IIa muscle fibers are “fast-twitch” and have higher capacity for rapid force generation, and lower resistance to fatigue due to greater anaerobic energy supply. Type IIx muscle fibers are “fast twitch” and have greater capacity for rapid force generation, and lower resistance to fatigue than Type IIa fibers.
Which chamber of the heart sends oxygenated blood into systemic circulation?
A:) Left Atria
B:) Left Ventricle
C:) Right Atria
D:) Right Ventricle
Answer:
The left ventricle. The right atria receives deoxygenated blood from systemic circulation and sends this blood into the right ventricle. The right ventricle sends deoxygenated blood into pulmonary circulation so the blood can release CO2 and pick up oxygen in the lungs. Oxygenated blood returns from pulmonary circulation to the left atria. The left atria sends oxygenated blood to the left ventricle. The left ventricle sends oxygenated blood into systemic circulation.
Which of the following structures are part of the “appendicular” skeleton?
A:) Femur
B:) Skull
C:) Vertebral Column
D:) Ribs
E:) Sternum
Answer:
Femur. The axial skeleton consists of the skull (cranium), vertebral column (vertebra C1 through the coccyx), ribs, and sternum. The appendicular skeleton includes the shoulder (or pectoral) girdle (left and right scapula and clavicle); bones of the arms, wrists, and hands (left and right humerus, radius, ulna, carpals, metacarpals, and phalanges); the pelvic girdle (left and right coxal or innominate bones); and the bones of the legs, ankles, and feet (left and right femur, patella, tibia, fibula, tarsals, metatarsals, and phalanges).
Proprioceptors located near the myotendinous junction are called…
A:) Alpha Motor Neurons
B:) Extrafusal Muscle Fibers
C:) Golgi Tendon Organs
D:) Muscle Spindles
Answer:
Golgi Tendon Organs. Golgi Tendon Organs (GTOs) are proprioceptors located in tendons near myotendinous junctions. GTOs relay information back to the central nervous system, causing the muscle(s) attached to the tendon being stretched to be reflexively inhibited. This functions to protect the body from generation of excessive tension.
Tachycardia is a heart rate that is greater than…
A:) 60 beats per minute
B:) 70 beats per minute
C:) 80 beats per minute
D:) 90 beats per minute
E:) 100 beats per minute
Answer:
100 beats per minute. Resting heart rate normally ranges between 60 – 100 beats per minute. Less than 60 beats per minute is bradycardia. More than 100 beats per minute is called tachycardia.
Movement of the diaphragm generates positive pressure within the thoracic cavity. Is the diaphragm contracting or relaxing?
A:) Contracting
B:) Relaxing
Answer:
Relaxing. When you exhale, the diaphragm is relaxing and moving upward within the thoracic cavity. The shortening of the thoracic cavity reduces the negative pressure within the cavity, pushing air out of the lungs.
Which portion of an electrocardiogram displays heart ventricle repolarization?
A:) P-Wave
B:) QRS Complex
C:) T-Wave
Answer:
T-Wave. The T-Wave corresponds with ventricular repolarization.
CSCS Study Questions: Structure and Function of Body Systems
Essentials of Strength Training & Conditioning 4th Edition: Chapter 1
The human body is a complex and interconnected system made up of various subsystems that work together to regulate our physical functions and movements. These systems include the muscular, skeletal, cardiovascular, respiratory, nervous, and endocrine systems. Each of these systems performs specific tasks in order to maintain our health and wellbeing, from delivering oxygen to our cells to helping us lift heavy objects. In order to understand how these systems work together to keep us healthy, we must first understand the structure and function of each individual system.
The muscular system is responsible for our ability to move our bodies. It is made up of skeletal muscles, which are attached to our bones and allow us to produce the force necessary for movement. These muscles are activated by the nervous system, which sends signals from the brain to the muscles telling them when to contract. The skeletal system provides support and structure for our bodies. It is made up of bones, which provide a framework for our muscles to attach to and also protect our vital organs. The joints between our bones allow us to move our limbs and allow us to produce force during physical activity.
The cardiovascular system is responsible for transporting oxygen and nutrients throughout the body, while also removing carbon dioxide and metabolic waste products. It consists of the heart, which pumps blood through a network of blood vessels, including arteries, veins, and capillaries. The respiratory system helps provide oxygen to our cells by facilitating gas exchange in the lungs. It is made up of the nose, mouth, pharynx, larynx, trachea, bronchi and lungs. Finally, the nervous system provides us with control over our movements and sensations through a network of neurons that transmit information between body parts and the brain.
All of these systems work together to maintain our health and wellbeing. By understanding the structure and function of each system, we can better understand how they work together to keep us healthy.
The Essentials of Strength Training & Conditioning 4th Edition textbook chapter 1 was written by N. Travis Triplett, Ph.D. These CSCS study questions contain a general overview of basic exercise science, exercise physiology, and human anatomy that will be relevant for taking the Certified Strength and Conditioning Specialist (CSCS) exam. This chapter covers macrostructure and microstructure of muscle and bone, the sarcomere, sliding filament theory, muscle cell activation, muscle fiber types and characteristics, motor units, proprioceptors (muscle spindles and golgi tendon organs) and their purpose, heart anatomy and function, electrocardiogram, blood vessels, the lungs, and air exchange.

Certified Strength and Conditioning Specialist Exam
The Certified Strength and Conditioning Specialist (CSCS) exam by the National Strength and Conditioning Association (NSCA) is a four-hour-long, pencil and paper or computer-based examination. The Certified Strength and Conditioning Specialist exam has two sections: “Scientific Foundations” and “Practical / Applied.” Each of these sections consist of questions that the National Strength and Conditioning Association (NSCA) feels are relevant to test the knowledge and experience of a candidate for the Certified Strength and Conditioning Specialist (CSCS) professional credential. Certified strength conditioning specialist questions in the Scientific Foundations section include anatomy, exercise physiology, biomechanics, and nutrition. Certified strength conditioning specialist questions in the Practical / Applied section include program design, exercise techniques, testing and evaluation, and organization / administration (NSCA, 2015).
