muscular system

Question 1

muscle fibers are organized into fasicles and are classified by

Answer 1

fascicle to tendon relationship and fascicle organization

Question 2

parallel muscles

Answer 2

parallel to long axis, tension dependent on # of myofibrils
(biceps, rectus abdominis, supinator)

Question 3

convergent muscles

Answer 3

broad area will converge on attachment site (tendon, raphe, aponeurosis)
fibers will move in different directions dependent on stimulus

Question 4

pennate muscles

Answer 4

forms an angle with tendon
less movement, more myofibrils & tension than parallel muscles
(extensor digitorum, rectus femoris, deltoid)

Question 5

circular muscles

Answer 5

sphincters
open & close to guard body entrances
