Ch. 4.8 Muscle Tissue

Question 1

Skeletal muscle TISSUE

Answer 1

• Contains large muscle cells that are long & slender; usually called muscle fibers
• Multinucleate
• Incapable of dividing

Question 2

Myosattelite cells (satellite cells)

Answer 2

Stem cells that persist in adult skeletal tissue; used to produce new muscle cells (fibers)

Question 3

Striations

Answer 3

Artifacts from the organization of actin and myosin filaments into repeating groups

Question 4

Striated Voluntary Muscle

Answer 4

Skeletal Muscle

Question 5

Skeletal MUSCLE

Answer 5

• An organ that contains all four tissue types, but where muscle tissue predominates
• Adjacent fibers tied together by elastin and collagen fibers

Question 6

cardiocyte

Answer 6

• A typical cardiac muscle cell
• Usually one, up to five nuclei

Question 7

Cardiac muscle tissue

Answer 7

• Only in heart
• Striations, actin and myosin filaments arranged in the same way as skeletal muscle
• More extensive network between cells
• Limited repair ability

Question 8

Intercalated discs

Answer 8

• Region where the extensive connections between cardiac muscle cells come together
• Locked my desmosomes+proteoglycans and gap junctions

Question 9

Striated involuntary muscle

Answer 9

cardiac muscle tissue

Question 10

Nonstriated involuntary muscle

Answer 10

smooth muscle

Question 11

smooth muscle tissue
