Answer 1

something inserted. e.g., intercalated disc: membranous band that connects cardiac muscle cells.

Question 2

erg-

Answer 2

work. e.g., synergist: a muscle that works with a prime mover, producing a movement.

Question 3

fasc-

Answer 3

bundle. e.g., fasciculus: bundle of muscle fibers.

Question 4

-gram

Answer 4

something written. myogram: recording of a muscular contraction.

Question 5

Answer 5

over, more. e.g., muscular hypertrophy: enlargement of muscle fibers.

Question 6

inter-

Answer 6

between. e.g., intercalated disc: a membranous band that connects cardiac muscle cells.

Question 7

iso-

Answer 7

equal. e.g., isotonic contraction: contraction during which the tension in a muscle remains unchanged.

Question 8

laten-

Answer 8

hidden. e.g., latent period: period between a stimulus and the beginning of a muscle contraction.

Question 9

myo-

Answer 9

muscle. e.g., myofibril: contractile fiber of a muscle cell.

Question 10

reticul-

Answer 10

a net. e.g., sarcoplasmic reticulum: network of membranous channels within a muscle fiber.

Question 11

sarco-

Answer 11

flesh. e.g., sarcoplasm: substance (cytoplasm) within a muscle fiber.

Question 12

Answer 12

together. e.g., synergist: muscle that works with a prime mover, producing a movement.

Question 13

tetan-

Answer 13

stiff. e.g., tetanic contraction: sustained muscular contraction.

Question 14

-tonic

Answer 14

stretched. e.g., isotonic contraction: contraction during which the tension of a muscle remains unchanged.

Question 15

-troph

Answer 15

well fed. e.g., muscular hypertrophy: enlargement of muscle fibers.

Question 16

voluntar-

Answer 16

of one’s free will. e.g., voluntary muscle: muscle that can be controlled by conscious effort.

Question 17

Tendons

Answer 17

attaches muscles to bone.

Question 18

Ligaments

Answer 18

attaches bone to bone.

Question 19

Epimysium

Answer 19

are layers of connective tissue that closely surrounds a skeletal muscle.

Question 20

Perimysium

Answer 20

are layers of connective tissue that extend inward from the epimysium and separate the muscle tissue into small sections. It is layers of connective tissue that separate a muscle into small bundles called fascicles.

Question 21

Fascicles

Answer 21

Contains bundles of skeletal muscle fibers.

Question 22

Endomysium

Answer 22

are thin layers of connective tissue that surround an individual muscle fiber.

Question 23

Sarcoplasm

Answer 23

The cytoplasm of a muscle fiber.

Question 24

Fascia

Answer 24

are connective tissue located between adjacent muscles.

Question 25

Transverse (T) tubule

Answer 25

Membranous channel extending inward from muscle fiber membrane.

Question 26

Sarcolemma

Answer 26

The cell membrane of a muscle fiber.

Question 27

Myosin

Answer 27

Protein found in thick filament

Question 28

Actin

Answer 28

Protein found in thin filament
