Smooth muscle contraction

Question 1

What are the similarities between smooth muscle contraction and skeletal muscle contraction?

Answer 1

Both types involve reaction between actin and myosin

Both types are stimulated by membrane impulses, require an increase in calcium ions in cells and use ATP energy

Question 2

What are the differences in neurotransmitters between smooth muscle contraction and skeletal muscle contraction?

Answer 2

Both acetylcholine and norepinephrine stimulate and inhibit smooth muscle contraction while only Acetylcholine stimulates skeletal muscle

Question 3

What are the differences between hormones in smooth muscle contraction and skeletal muscle contraction?

Answer 3

Hormones can stimulate or inhibit contraction of smooth muscle but not skeletal muscle

Question 4

What are the similarities between contraction and relaxation of smooth muscle contraction and skeletal muscle contraction?

Answer 4

smooth muscle is slower to contract and relax

Smooth muscle maintain a contraction longer with them same amount of ATP

Question 5

What are the similarities between contraction and ATP of smooth muscle contraction and skeletal muscle contraction?

Answer 5

smooth muscle maintains a contraction longer with the same amount of ATP

Question 6

What are the similarities between changing of length of smooth muscle contraction and skeletal muscle contraction?

Answer 6

smooth muscle can change length without change in tautness
