Chapter 9 Exam 2 Flashcards
provides movement for the body in conjunction with support from the bones
Muscular system
one of three types of muscles in the body; but the only one that is under voluntary control
Skeletal Muscle
sac of synovial membrane that contains synovial fluid; decreases friction where a tendon rubs against a bone near a synovial joint
Bursa
Burs/o-
bursa
Thin connective tissues sheet around each muscle fascicle and around the muscle itself; merges to become part of the tendon
Fascia
Fasci/o-
fascia
where the tendon of a muscle ends on a bone that moves as the muscle contracts or relaxes
insertion
where the tendon of a muscle begins and is attached to a stationary (or nearly stationary) bone
Origin
cordlike; white band of neoelastic fibrous connective tissue that attaches a muscle to a bone
Tendon
Tendin/o-
Tendon
moving a body part away from the midline
abduction
moving a body part toward the midline
Adduction
straightening and extending a joint to increase the angle between 2 bones or two body parts
Extension
bending a joint to decrease the angle between two bones or body parts
Flexion
Turning the palm of the hand posteriorly or downward
Pronation
moving a body part around its axis
Rotation
Turning the palm of the hand anteriorly or upward
Supination
muscle of the side of the face that moves the cheek
buccinator muscle
Buccinat/o-
cheek
muscle of the side of the face that moves the mandible upward
Masseter muscle
Masset/o-
chewing
muscle of the neck thatbends the head toward the sternum (flexion) and turns the head to either side (rotation)
sternocleido-mastoid muscle
muscle of the shoulder that raises the arm and moves the arm away from the body (abduction)
deltoid muscle
Delt/o-
triangle
muscle of the back that moves the arm posteriorly and medially toward the verebral column (adduction)
latissimus dorsi muscle
muscle of the chest that moves the arm anteriorly and medially across the chest (adduction)
pectoralis major muscle
Pector/o-
chest
muscle of the shoulder that raises the shoulder; pulls the shoulder blades together; and elevates the clavicle
Trapezius muscle
muscle of the anterior upper arm that bends the upper arm toward the shoulder (flexion) and bends the lower arm toward the upper arm (flexion)
biceps brachii muscle
muscle of the posterior upper arm that straightens the lower arm (extension)
triceps brachii muscle
