Question 17

THREE MAJOR TYPES OF
SKELETAL MUSCLE FIBERS

Answer 17

1.SLOW OXIDATIVE FIBERS
(TYPE 1)- RED FIBERS
2. FAST OXIDATIVE FIBERS (TYPE
II)- INTERMIDIATE
3. FAST GLYCOTIC FIBERS (TYPE
IIB)- WHITE FIBERS

Question 18

High fatigue resistance, enabling
them to sustain contractions for long
periods.

Answer 18

SLOW OXIDATIVE FIBERS
(TYPE 1)- RED FIBERS

Question 19

Allow them to sustain contractions
for moderate periods.

Answer 19

FAST OXIDATIVE FIBERS (TYPE
II)- INTERMIDIATE

Question 20

Low fatigue resistance, they can only
sustain contractions for short periods.

Answer 20

FAST GLYCOTIC FIBERS (TYPE
IIB)- WHITE FIBERS
Low fatigue resistance

Question 21

sensory receptors that
provide the central nervous system
with information about the position
and movement of the body.

Answer 21

Proprioceptive organs in skeletal
muscles

Question 22

TWO MAIN TYPES OF PROPRIOCEPTIVE ORGANS IN SKELETAL MUSCLES

Answer 22

MUSCLE SPINDLES
GOLGI TENDON ORGANS

Question 23

Responsible
for sensing muscle length and
the rate of change.

Answer 23

muscle spindles

Question 24

Responsible for sensing muscle
tension

Answer 24

GOLGI TENDON ORGANS

Question 25

specialized type of muscle tissue that
makes up the walls of the heart.

Answer 25

cardiac muscle

Question 26

allow for
rapid and coordinated transmission
of electrical impulses throughout
the heart.

Answer 26

intercalated disc

Question 27

INTERCALATED DISCS CONTAIN THREE
TYPES OF JUNCTIONS:

Answer 27

GAP JUNCTIONS
DESMOSOMES
FASCIA ADHERENS

Question 28

Allow for the
direct passage of ions between
adjacent cells, ensuring
synchronized contraction.

Answer 28

gap junctions

Question 29

Provide strong
mechanical attachments
between cells, preventing them
from pulling apart during
contraction.

Answer 29

desmosomes

Question 30

Anchor
actin filaments, contributing to
force transmission during
contraction.

Answer 30

fascia adherens

of internal membranes within the
cardiomyocyte that stores and releases
calcium ions

Answer 31

sarcoplasmic reticulum
