Q

Smooth muscle

A
  • non-striated
  • walls of the hollow internal organs such as blood vessels, the gastrointestinal tract, bladder, and uterus.

Q

Muscle Fiber

A

The muscle cell

18
Q

Myofibril

A

Longitudinal bundle of myofilaments within a muscle cell

19
Q

Myofilaments

A
  • the contractile protein within a muscle cell

- actin and mysosin

20
Q

Actin

A

thin filaments

21
Q

Myosin

A

thick filaments

22
Q

Sarcomere

A
  • The segment that runs from Z line to Z line.
  • Both skeletal muscle and cardiac muscle have sarcomeres.
  • Smooth muscle has no sarcomeres.
23
Q

A band

A

darker staining band

24
Q

I band

A
  • The light band.

- made of thin filaments.

25
Q

Z line

A

runs through the I band

26
Q

M line

A

runs through the H band

27
Q

H band

A

bisects the A band

28
Q

Motor unit

A

A single motor neuron and the aggregation of muscle fibers innervated by that single neuron

29
Q

Motor Neuron

A

A neuron which innervates a muscle cell

30
Q

Motor end plate

A

The point of contact where a neuron contacts a muscle

31
Q

Neuromuscular spindle

A

A receptor which is sensitive to stretching of the muscle

32
Q

Neurotransmitter

A

the chemical released by a nerveat a synapse

33
Q

Red fibers

A
  • smaller in diameter
  • more mitochondria
  • slow-twitch muscle
  • more resistant to fatigue
  • more myoglobin
  • for endurance
34
Q

White fibers

A
  • larger diameter
  • fast-twitch muscle
  • store glycogen and use anaerobic metabolism
  • burst of power
