This energy system provides immediate energy through the breaking down of these
stored high energy phosphates. If this energy system is 'fully stocked' it will provide
energy for maximal intensity, short duration exercise for between10-15 seconds before
it fatigues - ANSWER ATP-PC Energy system adenosine triphosphate (ATP) and
phosphocreatine (PC).
ATP-PC (phosphagen system, anaerobic glycolysis system lactic acid and aerobic
oxygen system - ANSWER What are the body's 3 sources of ATP
Each muscle cell contains a limited amount of ATP. ATP-adenosine triphosphate-is how
your body utilizes biochemicals to store and then use energy. There is enough ATP in
the cell that the muscle can immediately use, but only enough for about three seconds.
The muscle must replenish the ATP levels quickly using a high-energy phosphate
compound called creatine phosphate.
An enzyme, known as creatine kinase, off the creatine phosphate and bonds it to ADP to
produce ATP. The cell then has ATP that it breaks down into ADP and then the
phosphagen has the ADP and turns it back into ATP. The muscle continues to do work
and over time, the levels of creatine phosphate begin to deplete. These working levels of
ATP and creatine phosphate together constitute what is known as the phosphagen
system. This phosphagen system supplies the energy needs of working muscle, but only
for 8 to 10 seconds. - ANSWER Phosphagen System
ATP production during high intensity, short duration exercise *provides energy for up to
15 sec. - ANSWER What is the phosphagen system used for?
-Major supplier of ATP *Stored glycogen is split into glucose and than into pyruvic acid. -
the energy released is ATP.
-forming lactic acid
,*Does not use o2
-Only substrate used is carbohydrates(glycogen and glucose)
-Enough energy released to resynthesize only a small amount of ATP. - ANSWER
Anaerobic Glycolysis -
high intensity, short duration exercise - ANSWER Anaerobic glycolysis system supplies
ATP during what?
used during low intensity, long duration exercise such as running a marathon.
*produces the most ATP but needs complex chemical reaction
*This system will provide energy as long as there are nutrients to utilize. - ANSWER
Aerobic metabolism
low intensity, long duration activities, - amount of ATP production is greaters but
requires a complicated series of chemical reactions - ANSWER Aerobic system supplies
ATP during?
Anatomical Position - ANSWER Erect posture of the body with the face forward, feet
pointing forward and slightly apart, arms at the side, and palms forward with fingers and
thumbs in extension .
Frontal -divides body into anterior and posterior sections Ex: Abduction and Adduction
sagittal - Divides body into right and left sections Ex: Flexion and Extension
transverse -divides body into upper and lower sections Ex: medial and lateral rotation -
ANSWER 3 cardinal planes of the body
Suture, Syndesmosis, Gomphosis - ANSWER Fibrous Joints (there are 3)
Synarthroses - ANSWER Another term for fibrous joints
Skull
-union of 2 bones by a ligament or membrane
,-immovable joint - ANSWER Example of a suture joint
Ex: tibia and fibula with interosseous membrane
-bone connected to bone by a dense fibrous membrane or cord
-very little motion - ANSWER Ex: of syndesmosis
Ex: Tooth in socket
-2 bony surfaces connect as a peg in a hole - ANSWER Ex: of gomphosis
synchondrosis and symphysis - ANSWER 2 types of cartilaginous joints
amphiarthroses - ANSWER Another term for cartilaginous joints
Ex: sternum and true rib articulation
*Provides SLIGHT motion
-hyaline cartilage
-cartilage adjoints two ossifying centers of bone
-provides stability during growth - ANSWER Synchondrosis
Ex: pubic symphysis
*Provides SLIGHT motion
-2 bones covered with hyaline cartilage and connected by fibrocartilage - ANSWER
Symphysis
Uniaxial joint
biaxial joint
multi-axial joint - ANSWER 3 Types of synovial joints
, diarthroses - Free movement - ANSWER another name for synovial joints
*Provide what type of movement?
Synovial - ANSWER Which joints are them most complex and vulnerable to injury?
joint cavity, articular cartilage, snynovial membrane, synovial fluid and fibrous capsule -
ANSWER Synovial joints have 5 distinguishing characteristics. what are they?
one motion around a single axis in one plane of the body
Ex: Hinge - elbow
Pivot - atlantoaxial joints - ANSWER Give 2 examples of an uniaxial joint
Movement occurs in 2 planes and around 2 axes through the convex/concave surfaces.
-Condyloid- metacarpophalangeal joint of finger
Saddle - carpometacarpal joint of thumb - ANSWER Biaxial joint
motion occurs in 3 planes and around 3 axes
Ex: plane (gliding)- carpal joints
ball and socket - hip joint - ANSWER Multi-axial joint
free nerve endings, golgi ligaments endings, golgi-mazzoni corpuscles, pacinian
corpuscles and ruffini endings - ANSWER Common joint receptors?
Location - Joint capsule, ligamets, synovium, fat pads
Sensitivity - sensitive to non-noxious mechanical stress and noxious mechanical or
biochemical stimuli
Distribution - all joints - ANSWER Joint receptors (Free Nerve endings)
-Location
-Sensitivity
-Primary distribution
