Q

Types of muscle fibers

A

Type I (red) slow twitch
White fast twitch (llb)
Intermediate (lla)

33
Q

Type I (red) slow twitch

A

Dark, long acting, slow contracting, oxygen rich, generates ATP, and many mitochondria.

34
Q

White fast twitch (llb)

A

Large, pale, anaerobic, slow acting/fast contracting, and few mitochondria

35
Q

Intermediate (lla)

A

Slow, large amount of myoglobin/many capillaries/dark red, many mitochondria, and Use ATP fast.

36
Q

Where are the fiber types located?

A

Neck- Slow twitch
Shoulder- fast twitch
Legs- Mixture of slow, fast and intermediate.

37
Q

Epimysium

A

An outer sheath surrounding the entire muscle

38
Q

Perimysium

A

A sheath surrounding a bundle of muscle fibers

39
Q

Endomysium

A

A sheath surrounding each single muscle fiber

40
Q

Sarcoplasmic reticulum (SR)

A

Encircles the myofibril

41
Q

Motor Unit

A

The motor neuron and all the muscles fibers it innervates

42
Q

What is a slide filament?

A

The mechanism of the muscle contractions where the protein filaments slide to generate the shorten/movement.

43
Q

Myosin

A

A thick filament that it head attaches to actin (thin/twisted filament) and pulls the sarcomere together

44
Q

Troponin

A

What calcium binds to move the tropomyosin

45
Q

Tropomyosin

A

Covers the myosin

46
Q

What systems are apart of the Muscular System?

A

Respiratory System and Cardiovascular System

47
Q

Respiratiory System

A

Oxygen is needed for the muscles to work

48
Q

Cardiovascular System

A

Heart pumps the blood with nutrients and oxygen

49
Q

What percent of the bodies weight is muscle?

A

More than 40%

50
Q

What muscle remains contacted the longest?

A

The cardiac muscle

51
Q

What percent of muscle contracted does it shorten the normal length?

A

About 70%

52
Q

Muscle Bellies

A

Main portion between tendons (contraction)

53
Q

Tendon

A

At the end of muscle, attach to the bone

54
Q

Fascia

A

Encloses and separates muscle from skin

55
Q

Are muscle covered by fascia?

A

True

56
Q

Muscle Fibers

A

Long Cylinder cell

57
Q

Motor Neuron

A

Extended from spinal cord, sends message to have muscle contract.
-Single neuron innervates many fibers
-Small (20-30 fibers)
-Large (700 fibers)

58
Q

Motor Endplates

A

Neurons send impulse across motor endplates, find the neuron at the center of each muscle fiber

59
Q

Origin

A

Where the tendon of the muscle starts. The attachment of the muscle tendon to the stationary bone

60
Q

Insertion

A

Where the tendon of a muscle ends. The attachment of the muscle other tendon to the moveable bone

61
Q

Agonist

A

The muscle shortening or contracting

62
Q

Antagonist

A

The muscle that is lengthening

63
Q

Synergist

A

(assisting) muscles that help in the contraction

64
Q

Stabilizers

A

(at the proximal position) anchors the joint

65
Q

DOMS

A

Delayed Onset Muscle Soreness

66
Q

Benefits of stretching

A
  1. Improve physical performance
  2. Decrease risk of injury
  3. Reduces muscle soreness
  4. Improved posture-
