Free NFPT Human Anatomy and Physiology Questions and Answers

Question 1

A soft tissue structure called a ligament connects what?

Accepted Answer

Muscle to bone

Answer

Explanation:
Ligaments are tough bands of fibrous connective tissue that connect bones to other bones at joints. They provide stability and support to the joint by limiting excessive movement. Therefore, ligaments primarily connect bone to bone, not muscle to organ or other structures mentioned in the options.

Question 2

The external factors in stress management upon the body are termed by what?

Accepted Answer

Environmental

Answer

Explanation:
Environmental factors refer to the external influences and surroundings that can impact an individual's stress levels and overall well-being. In stress management, understanding and managing environmental factors such as work environment, living conditions, social surroundings, and exposure to noise or pollutants are crucial for promoting health and reducing stress.

Question 3

The Valsalva maneuver is generally used by who?

Accepted Answer

Anaerobic athletes during maximum explosion.

Answer

Explanation:
The Valsalva maneuver involves forcefully exhaling against a closed airway, typically by closing the mouth and pinching the nose shut. This technique is commonly used by anaerobic athletes during maximal efforts, such as weightlifting or powerlifting, to create intra-abdominal pressure and stabilize the core during intense lifts or explosive movements. It helps maintain spinal stability and support during heavy lifts, reducing the risk of injury.

Question 4

What muscle is the prime mover in a squat?

Accepted Answer

Quadriceps

Answer

Explanation:
During a squat exercise, the quadriceps muscles, specifically the rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius, are the primary movers responsible for extending the knee joint. These muscles work together to straighten the leg from a bent position, which is crucial in performing a squat movement. Therefore, the quadriceps are considered the prime movers or agonists in this exercise.

Question 5

What organelle is responsible for energy production?

Accepted Answer

Mitochondria

Answer

Explanation:
Mitochondria are organelles within cells that are responsible for producing energy in the form of adenosine triphosphate (ATP) through aerobic respiration. They are often referred to as the "powerhouses" of the cell due to their role in generating energy from nutrients. The Golgi complex is involved in packaging and modifying proteins, the nucleus contains genetic material and regulates cell activities, and the rough endoplasmic reticulum is involved in protein synthesis and transport.
