Question Answer
Which form of bone composes the outer portion that is very dense and hard and helps protect the internal bone components?Cortical
The area of senory nerve distribution of a nerve is called a dermatone
All joints permit varying degrees of motion. Which form of joint allows the greatest amount of motion?Ball and socket
The ability of a muscle or group of muscles to develop force rapidly is calledPower
As the speed of muscle shortening increases, the force the muscle is capable of producing increases (T or F)False-It decreases.
The name for a muscle action is which a muscle is lengthing while developing force is calledEccentric
Which form of bone has a longer length than width?Long bone
The sternoclavicular joint is an example of a Saddle shaped joint
The type of muscle that helps the agonist perform a certain action is called the synergist
The basic functional unit of a muscle is the sarcomere
The ability of a muscle fiber to return to its original length once the stretch on it is removed iselasticity

which form of joint receptors found in the capsule or synovium are sensiitive to stretch at the extremes of motion?ruffini endings
which muscle fibers are always activated first with activitytype 1
an arthrokinematic joint position that places the capsules and ligaments on maximal tension with approximation of the joint surfaces is considered which type of position?close packed position
a single muscle can contain many motor units, T or FTrue
immobilzation in a shortened position as you age can increase the thickening of the endomysium in a muscle, T or FTrue
