System Overview I
The 3 different types of muscle tissue in the body.
What are smooth, cardiac, and skeletal muscle?
The muscle contraction meaning “same measure”.
What is isometric contraction?
The covering of an entire muscle.
What is the epimysium?
The rotator cuff muscle on the anterior surface of the scapula.
What is subscapularis?
The boxer’s muscle.
What is the serratus anterior?
The functions of the skeletal muscle.
What are produce movement, maintain posture, stabilize joints, and generate heat?
The muscle with the major responsibility for a movement.
What is agonist?
The two calf muscles.
What are the gastrocnemius and soleus?
The muscle that is the prime mover for ankle dorsiflexion.
What is the tibialis anterior?
The workhorse of the elbow.
What is the brachialis?
The name of the protein that is the thin filament.
What is actin?
The contractile unit of a muscle fiber.
What is a sarcomere?
The three muscles of the hamstrings.
What are the biceps femoris, semitendinosus, semimembransosus?
This muscle has 3 heads but this is its 1 insertion point.
What is the olecranon process?
The only quad muscle that acts on TWO joints.
What is the rectus femoris?
The source of energy from direct phosphorylation.
What is creatine phosphate?
The skeletal muscle attachment that is described as “sheet-like”.
What is aponeuroses?
The visible banding of skeletal and cardiac muscle.
What is striations?
The muscle responsible for “hip-hiking”.
What is the quadratus lumborum?
This muscle on the tip of the shoulder is named after its shape. These are its origin, insertion, and action.
What is the deltoid:
origin - anterior border of lateral 1/3 of clavicle, acromion, & spine of scap
insertion – deltoid tuberosity
action – shoulder abduction?
The common reason for muscle fatigue.
What is oxygen debt?
The neurotransmitter for skeletal muscle.
What is acetylcholine (Ach)?
In terms of muscles and movement, origins attach to this type of bone whereas insertions attach to another.
What is origins attach to immoveable bone and insertions attach to moveable bone?
This muscle is not a hamstring or an adductor but part of the pes anserine group. Name the FOUR actions of this muscle.
What is hip flexion, abduction, external rotation (ER), knee flexion?
An eccentric contraction of the biceps brachii.
