Question 31

groups of muscle that work together within one part of the limb

Answer 31

Muscle compartments

Question 32

Surrounds these large muscle groups, separates it from other nearby muscles

Answer 32

Fascia and tough connective tissue

Question 33

Contains related muscles and the blood vessels/nerves that supply that muscle group

Answer 33

Fascia and tough connective tissue

Question 34

Supplies the muscle group that are often contained with the fascia that surrounds the compartment

Direct

Question 36

attachment via tendon. the tendon is an extension of the epimysium and the tendon merges with periosteum . Most muscles are indirect attachments eg. Bacips brachil

The end of the muscle that is more distal and inferior without regard for any particular movements or motion of the muscle

Answer 41

Distal or inferior end

Question 42

Answer 42

Agonist or prime mover

Question 43

Elbow flexion, prime mover is ?

Answer 43

Biceps brachii

Question 44

Muscles that work together to generate a particular motion

Answer 44

Synergistic

Question 45

Opposing muscles that whose contraction might inhibit the desired motion, these muscles may be relaxed in order to allow the desired motion to occur

Answer 45

Antagonistic

Question 46

Muscle that must be contracted during a motion that is actually generated by a prime mover in a different area ; without isometric contraction of the fixator, contraction of the prime over will generate a different motion

Answer 46

Fixator
