cpt study Flashcards
(134 cards)
The body’s ability to to sense the relative position of adjacent parts of the body
Ex: when walking our feet give us proprioception about the type of surface we are on.
Proprioception
specialized structures that recognize pressure in tissue and transmit signals to sensory nerves.
Mechanoreceptors
sensory receptors in the muscles that are parallel to the muscle fibers and are sensitive to change in muscle length. Spindles stretch with muscle and sends information to CNS.
helps to prevent muscles from stretching too far or too fast
Muscle Spindles
sensory receptors that are located at the point where the skeletal muscle fibers insert into the tendon. Sensitive to change in tension at the rate of change
causes the muscle to relax
Golgi Tendon Organs
Connective Tissue UNDER fascia that acts as an outer layer of the whole muscle
Epimysium
Connective tissue acts as an outer layer of fascicles
Perimysium
Between the individual muscle fibers
Endomysium
“Slow-Twitch”,smaller in size, less force produced, long term contractions (stabilization)
Type 1 Muscle Fiber
Fast-twitch, larger, quick to fatigue, force and power exercises
Type 2 Muscle Fiber
Prime Mover, main muscles
ex: chest press–> Pectoralis major
Agonist
Assist prime mover
ex: Chest press–> ant deltoid, tricep
Synergist
Stabilizes while prime mover and assist work.
Chest press–> rotator cuff
Stabilizer
Oppose Prime mover, chest press–> posterior delt
Antagonist
gather DEOXGENATED blood returning to the heart from ENTIRE BODY
Right Atrium
gathers OXYGENATED blood coming from the LUNGS
Left Atrium
thin walls pumps under low pressure. Pumps to lungs
Right ventricle
Thick walls, pumps under high pressure to rest of body
Left Ventricle
All of the chemical reactions that happen in our body to maintain itself. Nutrients are acquired, transported and used by the body.
Metabolism
Bioenergetics as it relates to the unique physiologic changes and demands on the body during excercies
Exercise Metabolism
where enzymes act
Substrates
Sugars, starches, and fiber. Provide the body with a source of fuel and energy required for all daily activities.
Carbohydrates
a simple sugar that comes from the digestion of carbs that is transported through the blood and is used or stored as energy
Glucose
the stored form of carbs, when needed it converts to glucose and used
Glycogen
a secondary source of energy
Fat
