Question 2

overview of skeletal muscle tissue:
-single nucleous or multiple?
-is it striated or non-striated?
-involuntary or voluntary controlled?
-Are their junctions present?

Answer 2

-Skeletal muscle is Striated
-Multinucleated (can have LOTS of nucelii)
-voluntary controlled by the somatic nervous system
-NO junctions between fibers

Question 3

overview of cardiac muscle:
-single nucleous or multiple?
-what word would you use to describe its arrangment?
-where is it located?
-are their junctions?
-is it striated or non striated?
-what type of control

Answer 3

-single nucleous
-cardiac muscle is branched
-cardiac muscle is in heart
-cardiac muscle has GAP junctions
-cardiac muscle is striated
-involuntary controlled

Question 4

overview of smooth muscle:
-where is it located?
-what is its shape?
-is it stiated or non-striated?
-are their junctions?
-what type of control?

Answer 4

-lining of internal organs
-spindle shaped
-cardiac muslce is non-striated
-their are gap junctions in some smooth muscle
-smooth muscle is involunatry controlled
