MUSCLE YISSUE

Question 1

Types of muscle tissue

Answer 1

Skeletal muscle
Cardiac muscle
Smooth muscle

Question 2

cytoplasm of muscle cells.

Answer 2

Sarcoplasm

Question 3

smooth ER of muscle cells.

Answer 3

Sarcoplasmic reticulum

Question 4

the muscle cell membrane and its external lamina.

Answer 4

Sacrolemma

Question 5

the process of tissue growth that is characterized by increased cell volume.

Answer 5

Hypertrophy

Question 6

the process of tissue growth by an increase in the number of cells.

Answer 6

Hyperplasia

Question 7

How does skeletal muscle forms

Answer 7

Myoblast → Myotube (protein & myofilament) → Striated muscle fibers → Skeletal muscle tissue.

Question 8

contain the major ion channels that control Ca2+ release from sarcoplasmic cisternae at myofibrils that initiates contraction.

Answer 8

caveole

Question 9

smaller encapsulated structures that enclose sensory axons penetrating among the collagen bundles at the myotendinous junction; detect changes in tension within tendons.

Answer 9

Golgi tendon organ

Question 10

sensory proprioceptors in which sensory axons wrap around intrafusal fibers in small specialized fascicles; mediate reflexes of varying complexity.

Answer 10

muscle spindles

Question 11

sensory receptor that provides the CNS with data from the musculoskeletal system.

Answer 11

proprioceptors

Question 12

anchored actin filament to z-disc.

Answer 12

α-actinin

Question 13

supports the thick myofilaments and connects them to the Z disc.

Answer 13

titin

Question 14

binds each thin myofilament laterally.

Answer 14

Nebulin

Question 15

corresponding to a region with only the rod-like portions of the myosin molecule and no thin filaments.

Answer 15

H-Zone

Question 16

bisects H zone that contains myomesin & creatine kinase.

Answer 16

M line

Question 17

specialized for Ca2+ sequestration and release and surrounds the myofibrils.

Answer 17

sacroplasmic reticulum

Question 18

a large complex with two identical heavy chains and two pairs of light chains.

Answer 18

myosin

Question 19

thin, helical filaments that run between the thick filaments.

Answer 19

actin

Question 20

an external sheath of dense irregular connective tissue, surrounds the entire muscle.

Answer 20

epimysium

Question 21

a thin connective tissue layer that immediately surrounds each bundle of muscle fibers termed a fascicle.

Answer 21

perimysium

Question 22

a very thin, delicate layer of reticular fibers and scattered fibroblasts that enveloped individual muscle fiber.

Answer 22

endomysium
