The part of the skeleton composed of the limbs and their attachments.
What is appendicular skeleton?
100
A place where two or more bones meet to connect parts and allow for movement in the body.
What is articulation?
100
A freely movable synovial joint.
What is diarthrosis?
100
A muscle that causes or controls joint motion through a specified plane of motion.
What is agonist?
100
The ability of a muscle to receive and respond to a stimulus.
What is excitability?
200
The axis of the body; consists of the head, vertebral column, rubs, and sternum.
What is axial skeleton?
200
Joint that allows movement in three planes around a central point.
What is ball-and-socket joint?
200
A limited-movement, nonsynovial joint.
What is synarthrosis?
200
A muscle usually located on the opposite side of a joint from the agonist and having the opposite action.
What is antagonist?
200
The ability of a muscle to be stretched or extended.
What is extensibility?
300
A tough, flexible connective tissue with a high water content that makes it softer than bone.
What is cartilage?
300
Joint that allows flexion and extension in one plane, changing the angle of the bones at the joint.
What is hinge joint?
300
The positioning of joints in such a way that motion at one of the joints is accompanied by motion at an adjacent joint.
What is closed kinematic chain?
300
A contraction in which the muscle shortens with tone because its contractile force is greater than the opposing force at attachments of the muscle.
What is concentric action?
300
A stabilizing muscle located at a joint or body part that contracts to stabilize the area, enabling another limb or body segment to exert force and move.
What is fixator?
400
The hard portion of the bone that surrounds spongy bone and helps proivde the firm framework of the body.
What is compact bone?
400
A bony projection from one bone fits into a ring formed by another bone and ligament structure to allow rotations around its own axis in one plane.
What is pivot joint?
400
A position in which the ends of the limbs or parts of the body are free to move without causing motion at another joint.
What is open kinematic chain?
400
A contraction in which the muscle lengthens with tone because its contractile force is less than the opposing force at the attachments of the muscle.
What is eccentric action?
400
A contraction in which the muscle stays the same length with tone because its contractile force equals that of the opposing force at the attachments of the muscle.
What is isometric action?
500
The lighter-weight portion of the bone, which is made up of trabeculae.
What is spongy bone?
500
Joint that is convex in one place and concave in the other with surfaces fitting together.
What is saddle joint?
500
A synarthrotic joint in which two bony compartments are joined directly by a thin layer of dense fibrous tissue.
What is suture?
500
The ability of a muscle to recoil and resume its original resting length after being stretched.
What is elasticity?
500
Movers of a joint other than the prime movers; assistant, secondary, or emergency movers.
