Myofibroblasts
36
135. Type of connective tissue cell which contains properties of smooth muscle cells://
Myofibroblasts
37
136. Macrophage of connective tissue://
Histiocyte
38
137. The smooth muscle is found in://
Smooth muscle fibers are located in walls of hollow visceral organs, except the heart,
(intestines, stomach)
39
138. Fiber type which makes up fast-twitch muscle://
White fibers
40
139. Fiber type which has more myoglobin://
. Red fibers
41
140. Line that divides the dark band in the muscles://
H Band
42
141. Region which of thin filaments://
I Band
43
142. The thin filaments is://
Myofilaments (actin)
44
143. Fiber type which is small in diameter://
Red fibers
45
144. The dark band in muscle is://
A Band
46
145. Regeneration of skeletal muscle tissue is dependent on://
Regeneration mainly depends upon satellite cells, myogenic progenitors localized between the basal lamina and the muscle fiber membrane.
47
146. The structural element of the smooth muscle tissue is://
Short, spindle-shaped, no evident striation, single nucleus in each fiber. they produce their own connective tissue, endomysium.

Cardiac muscle is striated muscle that is present only in the heart. Cardiac muscle fibers have a single nucleus, are branched, and joined to one another by intercalated discs that contain gap junctions for depolarization between cells and desmosomes to hold the fibers together when the heart contracts
