What is a primary cause of musculoskeletal degeneration in the adult population?
Overweight
a person with a BMI of 25 to 29.9
Blood Lipids
also known as cholesterol - carried in the bloodstream by protein molecules known as high-density lipoproteins and low density lipo proteins
Diabetes Mellitus
chronic metabolic disorder caused by insulin deficiency which impairs carbohydrates usage and enhances usage of fats and proteins
deconditioned
a state of lost physical fitness, which may include muscle imbalances, decreased flexibility and a lack of core and joint stability
proprioception
the cumulative sensory input to the central nervous system from all mechanoreceptors that sense body position and limb movement
Ligaments
Which term refers to fibrous connective tissues that connect bone to bone and provide static and dynamic stability as well as input to the nervous system?
Decreased oxygen delivery
Which of the following characteristics distinguishes type II muscle fibers from type I muscle fibers?
Mechanoreceptors
What are responsible for sensing distortion in body tissues and are located in muscles, tendons, ligaments, and joint capsules?
Cortisol
Which of the following is a catabolic hormone secreted by the adrenal glands and serves to maintain energy supply through the breakdown of carbohydrates, fats, and protein?
Pituitary gland
Which of the following glands releases growth hormone during childhood up until puberty?
Adrenal
Which gland produces the hormones (epinephrine and norepinephrine) that help prepare the body for activity and for the fight or flight response?
Appendicular skeleton
Which of the following is made up of the upper and lower extremities as well as the shoulder and pelvic girdles and encompasses approximately 126 bones?
They are sensitive to change in length of muscle and the rate of that change.
Which of the following is a characteristic of muscle spindles?
Golgi tendon organs
What are sensitive to changes in tension and the rate of that change, protecting a muscle from possible injury?
Arthrokinematics
Which term refers to the motion of a joint?
Heart
A hollow muscular organ that pumps circulation of blood through the body by means of rhythmic contraction
Mediastinum
The space in the chest between the lungs that contains all the internal organs of the chest except the lungs
Sinotrial (SA) Node
A specialized area of cardiac tissue, located in the right stream of the heart, which initiates the electrical impulses that determine the heart rate; often termed the pace maker of the heart
Atrioventricular Node (AV)
A small mass of specialized cardiac muscle fibers, located in the wall of the right atrium of the heart, that receives heartbeat impulses from the sinoatrial node and directs them to the walls of the ventricles
Atrium
The superior chamber of the heart that receives blood from its corresponding atrium, and in turn, forces blood into the arteries.
Stoke Volume
The amount of blood pumped out of the heart with each contraction
Cardiac Output
Heart rate x stroke volume, the overall performance of the heart
Blood Vessels
Network of hollow tubes that circulates blood throughout the body
Arteries
Vessels that transport blood away from the heart
Capillaries
The smallest blood vessels, and the site of exchange chemicals and water between the blood and the tissues
Veins
Vessels that transport blood from the capillaries toward the heart
Arterioles
Small terminal branches of an artery which end in capillaries
Venules
The very small veins that connect capillaries to the larger veins
Respiratory system
A system of organs (the lungs and respiratory passageways) that collects oxygen from the external environment and transports it to the bloodstream
Respiratory pump
Is composed of skeletal structures (ones) and soft tissues (muscle) that work together to allow proper respiratory mechanics to occur and help pump blood back to the heart during inspiration
Inspiration
The process of actively contracting the inspiratory muscles to move air into the body
Expiration
The process of actively or passively relaxing the inspiratory muscles to move air out of the body
Diffusion
The process of getting oxygen from the environment to the tissues of the body
inspiratory ventilation
active breathing
expiratory ventilation
both active and passive breathing
Resting Oxygen Consumption

Maximal Oxygen Consumption
The highest rate of oxygen transport and utilization achieved at maximal physical exertion
Maximal Oxygen Consumption
What may be the best measure of cardiorespiratory fitness?

Aorta
After leaving the left ventricle, blood enters this structure
Arteriole
Small terminal branch of an artery that ends in capillaries
Cardiac Output
