Muscle Contractions
Every muscle has these two attachment points
What are the origin and insertion?
This muscle is involved in flexing the elbow joint.
What is the Biceps Brachii?
The connective rope-like tissue that connects muscle to bone.
What is a tendon?
More involvement of these will increase the force of a muscle contraction
What are motor units(or muscle fibers)?
What is smooth muscle?
The Sliding Filament Theory of muscle contraction involves these two filaments.
What are Actin and Myosin?
This muscle group is the antagonist in flexing the knee joint
What is the quadriceps group?
The smallest contractile unit in a muscle.
What is a sarcomere?
This molecule is the involved in muscle contractions allowing the cells to relax.
What is ATP (Adenosine Triphosphate)?
Is voluntary and has striations.
What is skeletal muscle?
Muscle contraction potentially fails due to these two causes.
The name for this muscle comes from the Latin for "three heads"
What is the Triceps Brachii?
What is the epimysium/fascia?
This is production of ATP in the presence of oxygen.
What is aerobic respiration?
This muscle type is multinucleate.
What is skeletal muscle?
This is a muscle contraction in a laboratory setting involving only one muscle fiber that fully contracts and fully relaxes.
What is a twitch?
This the longest muscle in the human body.
What is the sartorius muscle?
The flattened sheath-like connective tissue attaching muscle to some anchor point.
What is aponeurosis?
Cellular respiration that produces ATP outside of the mitochondria.
What is Anaerobic Respiration?
Is arranged in longitudinal and cross-sectional fashion.
What is smooth muscle?
This results from the summing or contracting of muscle fibers where no relaxation occurs before being stimulated again.
What is Fused Complete Tetanus (Tetany)?
This muscle has it's origins on the maxilla bone and frontal bone and is involved in blinking the eyelids.
What is the orbicularis oculi?
These are the myofibrils in muscle tissue
What are Actin and Myosin?
The production of this molecule during anaerobic respiration decreases pH.
What is lactic acid?
What is cardiac muscle?
