200-QUESTIONS AND CORRECT DETAILED ANSWERS
Quiz Epimysium
Ans: The outer layer
Quiz Perimysium
Ans: Surrounding etching fascicules or groups of fiber
Quiz Endomysium
Ans: Surrounding individual fibers
Quiz Sliding-Filament theory of Muscular Contraction
Ans: states that the actin filaments at each end of the sarcomere slide inward on
myosin filaments, pulling the Z-lines toward the center of the sarcomere and thus
shortening the muscle fiber
Quiz SFT - resting phase
Ans: Little calcium is present in the myofibril (most stored in the sarcoplasmic
reticulum) so very few of the myosin cross bridges are bound to actin
Quiz SFT - Excitation-Contraction Coupling Phase
Ans: When the sarcoplasmic reticulum is stimulated to release calcium ions, the
calcium binders with troponin. A Protein that is situated at regular intervals a long the
actin filament
This causes a shift to occur in another protein molecule, tropomyosin which runs
along the length of the actin filament
The myosin cross bridge now attaches much more rapidly or the actin filament
Quiz SFT - Contraction Phse
,Ans: Energy for pulling action (power stroke) comes from hydrolysis (breakdown) of
adenosine tri phosphate (ATP) to adenosine diphosphate (ADP) and phosphate
Quiz SFT - Recharge Phase
Ans: Occurs as long as calcium is available in the myoibril, ATP is available to assist
in uncoupling the myosin from the actin, and sufficient active myosin ATPase is
available for catalyzing the breakdown of ATP
Quiz SFT - Relaxtion Phase
Ans: Occurs when the stimulation of the motor nerve stops
Calcium is pumped back into the sarcoplasmic reticulum, which prevent the link
between the actin and myosin filaments
Quiz Contraction of a Myofibril - Stretched
Ans: The I-Bands and H0Zone are elongated,m there is low force poetential due to
reduced cross bridge - actin alignment
Quiz Contraction of a Myofibril - Contracts
Ans: The I-Bands and H-zone are shortened
Quiz Contraction of a Myofibril - Completely contracted
Ans: There is a low force potential due to reduced cross-bridge - act alignment
Quiz Steps 1/5 of Muscle Contraction
Ans: 1. Initiation of ATP splitting (by Myosin ATPase) causes Myosin head to be in
an "energized" state that allows it to move into a position to be able to form a bond
with actin
Quiz Steps 2/5 of Muscle Contraction
Ans: 2. The release of phosphate from the ATP splitting process then causes the
myosin head to change shape and shift
Quiz Steps 3/5 of Muscle Contraction
Ans: 3. This pulls the acting filament in toward the center of the sarcomere and is
referred to as the power stroke : ADP is then released
Quiz Steps 4/5 of Muscle Contraction
,Ans: 4. Once the power stroke has occurred, the myosin head detaches from the
actin but only after another ATP binds to the myosin head because the binding
process facilitates detachment
Quiz Steps 5/5 of Muscle Contraction
Ans: 5. The myosin head is now ready to bind to another actin (as described in step
1), and the cycle continues as long as ATP and ATPase are present and calcium is
bound to the troponin
Quiz Type I (Slow twitch)
Ans: Efficient and fatigue resistant and have high capacity for aerobic energy
supply, but have limited potential for rapid force development
Characterized by low myosin ATPase Activity and low anaerobic power
Quiz Type IIa (Fast Twitch)
Ans: Inefficient and fatima lie and as having low aerobic power, rapid force
development, high myosin ATPase activity,and high anaerobic power
Quiz Type IIx
Ans: Show less resistance to fatigue then Type IIa
Quiz How can athletes improve force production
Ans: Incorporate phases of training that use heavier loads in order to optimize
neural recruitment.
Increase the cross-sectional area of muscles involved in the desired activity.
Perform multimuscle, multijoint exercises that can be done with more explosive
actions to optimize fast-twitch muscle recruitment.
Quiz Muscle Spindles
Ans: Are proprioceptors that consist of several modified muscle fibers enclosed in a
sheath of connective tissue
When a muscle is stretched, deformation of the muscle spindle activates the sensory
neuron, which sends an impulse to the spinal cord where it synapse with a motor
neuron, causing the muscle to contract
Quiz Golgi Tendon Organs (GTO)
Ans: Proprioceptors located in tendons near the myotendinous junction
Occur in series (attached end to end) with extramural muscle fibers
, Extremely heavy load is placed on the muscle, discharge of the GTO occurs
Sensory neuron of the GTO activates an inhibitory interneuron in the spinal cord,
which in turn synapses with and inhibits a motor neuron serving the same muscle
Quiz Ventricles of Heart pumps blood to
Ans: Right - the lungs
Left - rest of the body
Quiz Values of the heart - Tricuspid
Ans: Controls the flow of blood from your heart right atrium to the right ventricle
Quiz Valves of the Heart - Pulmonary
Ans: Three leaflets
Pumps blood from the right ventricle to the pulmonary artery
Prevents blood from going backwards
Quiz Valves of the Heart - Mitral
Ans: Bicuspid (two leaflets)
Bloods to flow from left atrium to left ventricle
Prevents backward flow
Quiz Valves of the Heart - Aortic Valve
Ans: Blood flow from your hearts left ventricle to the aorta
- aorta is the largest blood vessel, brings oxygenated blood from heart to the rest of
the body
Prevents backward flow from the aorta into left ventricle
Quiz Heart Conduction System
Ans: SA Node->AV Node->Bundle of His (AV Bundle)->Bundle Branches/Purkinje
Fibers
In charge of controlling the mechanical contraction of heart
Quiz Electrocardiography (ECG)
Ans: P wave - Arita depolarization
