|
What are striated muscles?
|
Striated = skeletal muscles, voluntary, has stripes, multiple nuclei shared within the same muscle fiber. Strong, but tire easily = shaped like long fibers.
|
|
What are smooth muscles?
|
Smooth = visceral, involuntary muscles, no stripes, single nucleus per cell. Weak, but doesn't tire easily = shaped like almonds, tapered on both ends
|
|
What are Cardiac muscles?
|
Cardiac = heart muscles, involuntary, has stripes, single nucleus per cell, strong and doesn't tire easily = highly branched, shaped like fibers cross-linked to one another.
|
|
Do we have abundant or sparse mitochondria in red muscle cells?
|
Abundant mitochondria is found in red muscle cells.
|
|
What type of endurance and agility do red muscle cells have?
|
Red muscle = high endurance, but slow.
|
|
What type of respiration is predominant in red muscle cells?
|
Aerobic respiration is predominant.
|
|
Why do red muscle cells have an abundance of mitochondria?
|
Many mitochondria because red muscles undergo aerobic respiration
|
|
How are red muscle cells equipped to receive abundant oxygen supply?
|
Equipped to receive abundant oxygen supply: many capillaries, many myoglobin.
|
|
What does high endurace in red muscle cells mean?
|
High endurace means red muscle cells doesn't tire easily.
|
|
What type of endurance and agility do white muscle cells have?
|
White muscle = fast, but fatigue easily.
|
|
What type of respiration is predominant in white muscle cells?
|
Anaerobic respiration (glycolysis) predominant.
|
|
Why do white muscle cells have few mitochondria?
|
Few mitochondria because white muscles undergo mainly glycolysis
|
|
How are white muscle cells equipped for short bursts of glycolysis?
|
White muscle cells are equipped for short bursts of glycolysis as they store high amounts of glycogen.
|
|
What are Pink muscle cells?
|
Pink muscle = intermediate between red and white muscle.
|
|
Among the contractile elements, describe the Actin filament.
|
Actin filament = thin filament = has troponin and tropomyosin on it.
