- adductors
- toward the midline of the body
- biceps
- muscle that has two origins
- minimus
- smallest of a group of muscles
- skeletal muscles
- tissue attached to and covering the skeletal system, voluntary, dense connective tissue packaging, referred to as the "muscular system"
- excitability
- the ability to receive and respond to a stimulus
- viscera
- digestive organs and blood vessels. smooth muscle
- brachialis
- found in the arm
- insertion
- the attachment of a muscle to a bone which moves when the muscles contracts
- brevis
- shortest of a group of muscles
- extensor
- involves movement that increases the angle between the articulating bones and straightens them

- cardiac muscle
- tissue found only in the heart where it contributes most of the mass of the heart wall, gap junctions called intercalated disks, coordinated activity is to act as a pump

- movement of a limb away from the midline of the body
- contractibility
- the ability to shorten when an adequate stimulus is received
- maximus
- largest of a group of muscles
- flexor
- a bending movement that decreases the angle of the joint and brings the two articulating bones closer together
- origin
- attachment of a muscle to a bone which does not move when muscle contracts

- tissue found in the walls of the visceral organs; nonstriated, spindle
- quadriceps
- muscle that has four origins
- rectus
- runs straight with the midline of the body
- cleido
- clavicle
- deltoid
- roughly triangular
- muscular system
- includes all structures of the body whose primary function is the movement of various body parts( movement)
- extensibility
- the ability to be stretched or extended
- longus
- longests of a group of muscles
- oblique
- runs at a diagonal line from the midline of the body
- transversus
- runs at right angles with the midline of the body
- intercostals
- found between ribs
- elasticity
- the ability of a muscle fiber to resume its resting length after it has contracted or has been stretched
