Components of the muscular system

5

What are tendons?

Tough bands of fibrous connective tissue that attaches the muscles to bone

6

Connective tissue that surrounds and connects all structures in the body

Fascia

7

Striated muscle

Muscle is responsible for the movements of the body that we can control

8

Non striated muscle

We do not have any control over this muscle
This muscle is found within the digestive system and other internal organs

9

The study of the function structure and disease of muscles

Myology

10

Muscle fiber- myocyte (muscle cell)
Endomysium- fascia that surrounds each muscle fiber
Fascicle- bundles of muscle fibers
Perimysium-fascia that surrounds the fascicles
Epimysium-fascia that surrounds the entire muscle

Structure of skeletal muscle tissue

11

What are two contractile proteins that work together in order to create movement within a muscle?

Actin
Myosin

12

What does origin mean?

The immovable attachment site- starting point

13

The middle part of the muscle- top part of the muscle

Belly

14

The moveable attachment site it will move towards the origin

Insertion

15

Decrease in muscle mass

Atrophy

16

What is the increase in muscle mass?

Hypertrophy

17

The ability of the muscle to contract

Contractibility

18

What is extensibility?

Ability of the muscle to stretch out and extend without causing injury

19

What is elasticity?

Ability of the muscle to return to its natural shape after contracting or extending

20

What stimulates muscle tissue?
