Tendons
structures at both ends of muscle that connects muscle to bone or cartilage. Because it is actually part of the muscle, it always binds muscle to another stucture (typically bone), attaching to the connective tissue of that skeletal structure. TERM 2
Ligaments
DEFINITION 2 tightly packed elastic structures that attach bone-to-bone, bone-to-cartilage or cartilage-to=cartilage TERM 3
Cartilage
DEFINITION 3 connective tissue embedded in matrix, capable of withstanding significant compressive and tensile forces. TERM 4
Aponeurosis
DEFINITION 4 sheet of tendon, muscles can attach to it when there's nothing else to attach to. (Useful in the abdomen.) TERM 5
The Motor Unit
DEFINITION 5 =one motor neuron + all of the muscle fibers it attaches to basis of muscle contraction and control of movement
Fine Motor Control
Rapid, controlled and precise movements (ex: fingers have to move ver precisely.) It has a very low innervation ratio each neuron controls a lower number of muscle fibers, but there are more motor neurons. Has more control over muscle fibers TERM 7
Gross Motor Control
DEFINITION 7 larger muscles make larger muscle contractions (legs and arms.) Has a high innervation ratio Has more muscle fibers, but less motor neurons TERM 8
Innervation Ratio
DEFINITION 8 Proportion of muscle fibers per number of motor neutrons Ratio of muscle fibers to motor neurons TERM 9
Agonist Muscle
DEFINITION 9 contracting, active, at any given moment and any given time. Muscles that move a structure or cause something to happen TERM 10
Antagonist Muscle
DEFINITION 10 opposes the movement (of the agonist muscle) at any give moment in time works against the agonist muscle
