Question

How would a drug that blocks acetylcholine release affect muscle contraction?

Answer 1

Answer:

Actylcholine is necessary for the skeletal muscle contraction, it serves as the  first step in the process that enables the formation of the cross bridge on the sarcomere.

The mysosin head and the actin myofilament combines to form a cross bridge. A drug that is interfering this cross bridge would prevent muscle contraction.

The acetylcholine helps in the breaking the interaction between the actin and myosin.

Answer 2

Answer:

The muscle tissue is important for the body movement and control the body action. The three main types of muscle tissue are cardiac muscle, smooth muscle and skeletal muscle.

The acetylcholine is the neurotransmitter that helps in the initiation of muscle contraction and leads to the cross bridge formation in the sarcomeres. The drug that affects the acetylcholine will not allow the cross bridge formation and prevent the muscle contraction.
