Muscle Types and/or Contractions
100
The muscle(s) used when holding a textbook, arms flexed, with two hands in front of your body.
What are the biceps?
100
This is the movable end where skeletal muscle attaches.
What is the insertion?
100
Normal tonicity of the muscles.
What is muscle tone?
100
During a squat, identify 3 major muscles used.
What is the gluteus maximus, quadriceps (rectus femoris, vastus lateralis, vastus medialis) hamstrings
100
This type of muscle is only found in the heart and propels blood throughout vessels.
What is cardiac muscle?
200
These muscles are used in knee extension within the sagittal plane.
What are the quadriceps? (vastus medialis, rectus femoris, and vastus lateralis)
200
This is deemed as a specific movement by a skeletal muscle.
What is an action?
200
This is a condition of increased tension of the muscles, meaning the muscle tone is abnormally rigid, hampering proper movement.
What is hypertonicity?
200
These muscles work together to perform a bench press.
What is the pectoralis major, trapezius and deltoids?
200
This type of muscle moves the body by pulling on bones of skeleton making movement possible.
What is skeletal muscle?
300
This muscle(s) abducts the upper arm in the frontal plane.
What are deltoids?
300
This is where a fixed end of a skeletal muscle attaches.
What is an origin?
300
A clinical manifestation characterized by weakness or paralysis and reduced muscle tone without other obvious cause.
What is flaccidity?
300
Order these muscles from superior to inferior: gastrocnemius, sternocleidomastoid, biceps brachii, biceps femoris, rectus abdominus.
What is sternocleidomastoid (neck), biceps brachii (arm), rectus abdominus (abs), biceps femoris (upper thigh), gastrocnemius (calf)
300
This type of muscle moves fluid and solids along digestive tract.
What is smooth muscle?
400
These muscles are the primary movers during a back extension exercise.
What are the erector spinae muscles? (iliocostalis, longissimus, and spinalis)
400
A muscle which helps an agonist work efficiently (by adding extra strength or pull).
What is a synergist muscle?
400
This state is characterized by an increase in muscle tone causing resistance to externally imposed joint movements.
What is rigidity?
400
These are the hamstrings muscles, laterally to medially.
What are the biceps femoris, semitendinosis, semimembranosus
400
Name three functions of skeletal muscle.
What is producing movement, maintaining posture, maintain body temperature, guard entrances and exits, support soft tissues, provide nutrient reserves?
500
These muscles are primary movers during a push-up.
What is the pectoralis major?
500
A type of contraction in which tension rises and skeletal muscle length changes.
What is isotonic contraction?
500
This is a condition of low muscle tone where muscles are too weak to support the body.
What is hypotonicity?
500
These are the four muscles involved with the rotator cuff.
What are the infraspinatus, teres minor, supraspinatus, subscapularis?
500
____________ muscles support, move and brace limbs whereas ____________ muscles support the axial skeleton.
What are appendicular and axial, respectively.
