mytology overview

Question 1

what are skeletal muscle fibers organized into

Answer 1

fascicles

Question 2

belly of muscles

Answer 2

part of the muscle that contains the muscle fibers and fascicles

Question 3

tendon

Answer 3

visible connective tissues

Question 4

epimysium

Answer 4

outermost layer of connective tissue

Question 5

types of fascicle arrangement

Answer 5

parallel, convergent, pennate, circular

Question 6

parallel fascicle arrangement

Answer 6

simple: force of contraction works to shorten muscle

Question 7

convergent fascicle arrangement

Answer 7

has a narrow attachment on one side and a broad attachment on the other side –> all parts of muscle make work together

Question 8

pennate fascicle arrangement

Answer 8

involves attachment at an angle to the tendon – have many more cells but much shorter cells and fascicles

Question 9

origin of muscle

Answer 9

the more stable attachment that is often more proximally or more medially located on the body

Question 10

synergists

Answer 10

(agonists) work in generally the same way

Question 11

example of synergist

Answer 11

brachii and brachialis muscle –> both flex the elbow joint

Question 12

antagonists

Answer 12

muscles that work opposite of eachother
