What is happening when the blood vessels narrow?
-
Hypotension
-
Hyperventilation
-
Vasoconstriction
Correct Answer
A. VasoconstrictionExplanation
Vasoconstriction refers to the narrowing of blood vessels. When blood vessels narrow, it reduces the diameter of the vessels, leading to a decrease in blood flow. This can occur in response to various stimuli such as cold temperatures, stress, or certain hormones. Vasoconstriction helps regulate blood pressure by increasing resistance to blood flow, which can be beneficial in certain situations, such as preventing excessive bleeding. However, prolonged or excessive vasoconstriction can lead to hypertension and decreased blood supply to tissues.Rate this question:

Where does the pulmonary artery carry blood from and to?
-
From the lungs to the heart
-
From the heart to the lungs
-
From the body to the heart
Correct Answer
A. From the heart to the lungsExplanation
The pulmonary artery carries blood from the heart to the lungs. This artery is responsible for transporting deoxygenated blood from the right ventricle of the heart to the lungs, where it picks up oxygen and gets rid of carbon dioxide through the process of respiration. Once the blood is oxygenated in the lungs, it returns to the heart through the pulmonary veins.Rate this question:

Which muscle crosses the anterior of the knee joint?
-
Hamstrings
-
Quadriceps
-
Gastrocnemius
-
Tibialis anterior
Correct Answer
A. QuadricepsExplanation
The quadriceps muscle crosses the anterior of the knee joint. This muscle is located on the front of the thigh and is responsible for extending the leg at the knee joint. When the quadriceps contracts, it straightens the knee joint, allowing for movements such as walking, running, and jumping. Therefore, the quadriceps is the correct answer as it is the muscle that crosses the anterior of the knee joint.Rate this question:

-
Heavy weight training
-
100 metre racing
-
Power lifting
-
Marathon running
Correct Answer
A. Marathon runningExplanation
Marathon running would burn fats in the presence of oxygen because it is an aerobic activity that requires sustained effort over a long period of time. During marathon running, the body relies on oxygen to produce energy, and as a result, it primarily burns stored fats for fuel. This type of endurance exercise helps to improve cardiovascular fitness and promote fat loss.Rate this question:

Which muscle contracts concentrically to laterally flex the spine?
-
Vastus lateralis
-
Hamstrings
-
Obliques
-
Iliopsoas
Correct Answer
A. ObliquesExplanation
The obliques are a group of muscles located on the sides of the abdomen. When they contract concentrically, they cause the spine to laterally flex, or bend sideways. This movement is important for activities such as bending to the side or twisting the torso. The other muscles listed (vastus lateralis, hamstrings, and iliopsoas) are not primarily responsible for lateral flexion of the spine.Rate this question:

Which of the following joints can laterally flex?
-
The Spine
-
The Knee
-
The Pelvis
-
The Shoulder Girlde
Correct Answer
A. The SpineExplanation
The spine is capable of lateral flexion. This means that it can bend sideways, allowing the torso to tilt to the left or right. The spine is made up of a series of vertebrae that are connected by joints, called facet joints. These joints allow for movement in different directions, including lateral flexion. This movement is important for activities such as bending to the side, reaching for objects, and twisting the torso. The other options, the knee, pelvis, and shoulder girdle, do not have the same capability for lateral flexion as the spine.Rate this question:

Which of the following joints can rotate?
-
The hinge joint of the knee
-
The hinge joint of the elbow
-
The shoulder girdle
-
The spine
Correct Answer
A. The spineExplanation
The spine is able to rotate because it is made up of a series of small bones called vertebrae that are connected by flexible joints. These joints allow for movement in multiple directions, including rotation. This allows the spine to twist and turn, enabling us to perform various movements such as twisting our torso or looking over our shoulder.Rate this question:

Which muscle is the agonist that contracts concentrically during knee extension?
-
Hamstrings
-
Soleus
-
Quadriceps
-
Option 4
Correct Answer
A. QuadricepsExplanation
The quadriceps muscle is the agonist that contracts concentrically during knee extension. When the quadriceps muscle contracts, it causes the knee joint to straighten or extend. This muscle group consists of four muscles: rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius. These muscles work together to generate the force necessary for knee extension and are responsible for movements such as walking, running, and jumping.Rate this question:

Which joint action occurs when the medial deltoids contract eccentrically?
-
Adduction
-
Inversion
-
Eversion
-
Abduction
Correct Answer
A. AdductionExplanation
When the medial deltoids contract eccentrically, they are responsible for controlling the movement of the arm away from the midline of the body. This movement is known as adduction. Therefore, when the medial deltoids contract eccentrically, the joint action that occurs is adduction.Rate this question:

Which of the following are components of motor fitness enhanced by exercise?
-
Reaction time and power
-
Muscular fitness and flexibility
-
Cardiovascular and respiratory fitness
-
Endurance and strength
Correct Answer
A. Reaction time and powerExplanation
The components of motor fitness that are enhanced by exercise include reaction time and power. Reaction time refers to the ability to respond quickly to a stimulus, and power refers to the ability to generate force quickly. Exercise can improve both of these components by increasing neural pathways and muscle strength, allowing for faster and more powerful movements.Rate this question:

Which joint action occurs if the biceps contract eccentrically?
-
Elbow flexion
-
Elbow extension
-
Shoulder adduction
-
Shoulder abduction
Correct Answer
A. Elbow extensionExplanation
When the biceps contract eccentrically, it means that the muscle is lengthening while still under tension. This action is responsible for controlling the movement of the arm as it extends at the elbow joint. Therefore, the correct joint action that occurs when the biceps contract eccentrically is elbow extension.Rate this question:

Which energy system uses glycogen without oxygen to produce adenosine triphosphate for higher intensity activities?
-
Creatine phosphate system
-
Adenosine diphosphate system
-
Lactate system
-
Aerobic system
Correct Answer
A. Lactate systemExplanation
The lactate system uses glycogen without oxygen to produce adenosine triphosphate (ATP) for higher intensity activities. During intense exercise, the body's demand for ATP exceeds the rate at which oxygen can be delivered to the muscles. In this anaerobic environment, glycogen is broken down into glucose, which is then converted into ATP through a process called glycolysis. Lactate is produced as a byproduct of this process. While lactate is often associated with fatigue and muscle soreness, it can be used as a quick source of energy during high-intensity exercise.Rate this question:

What joint action occurs when the erector spinae muscles contract eccentrically?
-
Horizontal extension
-
Horizontal flexion
-
Flexion
-
Extension
Correct Answer
A. FlexionExplanation
When the erector spinae muscles contract eccentrically, it means that they are lengthening while still being active. This action is commonly associated with controlling the movement of the spine during certain exercises or movements. Flexion refers to the forward bending of the spine, which is the joint action that occurs when the erector spinae muscles contract eccentrically. Therefore, flexion is the correct answer in this case.Rate this question:

Which muscle is located posterior to the spine?
-
Rectus abdomimis
-
Rectus femoris
-
Erector spinae
-
Serratus anterior
Correct Answer
A. Rectus abdomimisExplanation
The correct answer is Erector spinae. The erector spinae muscle group is located posterior to the spine. It runs along the vertebral column and helps to maintain proper posture and support the spine. The rectus abdominis muscle is located anteriorly, in the front of the body, and is responsible for flexing the trunk. Therefore, it is not located posterior to the spine.Rate this question:

Which of the following bones form part of the axial skeleton?
-
The spine, ribs and cranium
-
The femur, patella and tibia
-
The humerus, radius and ulna
-
The tarsals, metatarsals and phalanges
Correct Answer
A. The humerus, radius and ulnaExplanation
The humerus, radius, and ulna are bones that form part of the axial skeleton. The axial skeleton includes the bones of the head and trunk, which provide support and protection for the vital organs. The humerus is the bone of the upper arm, while the radius and ulna are the bones of the forearm. These bones contribute to the structure and stability of the axial skeleton, allowing for movement and providing attachment points for muscles.Rate this question:
