Front 1

3 types of muscles

Back 1

Cardiac: involuntary, banded appearance, dense connective tissue, acts as a pump
Smooth: involuntary, longitudinally and circularly arranged layers
Skeletal: banded appearance, figure8 packaging, moves bones and facial skin, referred to as the muscular system, voluntary

Front 2

F'n of muscles

Back 2

1. produce movement
2. maintain posture
3. stabilize joints
4. generate heat

Front 3

Perimysium

Back 3

Connective tissue surrounding a fascicle

Front 4

Epimysium

Back 4

Connective tissue ensheathing the entire muscle

Front 5

Sarcomere

Back 5

Z disc to Z disc
Contractile unit of a muscle

Front 6

Fiber

Back 6

a muscle cell

Front 7

Endomysium

Back 7

Thin connective tissue investing each muscle cell

Front 8

Sarcolemma

Back 8

Plasma membrane of the muscle cell

Front 9

Myofibril

Back 9

Long, filamentous organelle found within muscle cells that has a banded appearance

Front 10

Myofilament

Back 10

Acting or myosin containing structure

Front 11

Tendon

Back 11

Cordlike extension of connective tissue beyond the muscle, serving to attach it to the bone
1. provides durability
2. can cross rough bony projections that a muscle can't
3. small size so more room for more tendons

Front 12

fascicle

Back 12

a discrete bundle of muscle cells

Front 13

aponeuroses

Back 13

fibrous sheet connecting a muscle and the part it moves

Front 14

fascia

Back 14

separates out muscles

Front 15

Motor Unit

Back 15

a motor neuron and all the muscles cells it stimulates
