change in shape of lens.
The ciliary muscle is located within the eye and is responsible for controlling the shape of the lens, which is crucial for focusing on objects at different distances. Contraction and relaxation of the ciliary muscle affect the thickness of the lens, allowing for accommodation of near and far vision.
Breaking down acetylcholine can lead to muscle relaxation because acetylcholine is a neurotransmitter that stimulates muscle contraction. When acetylcholine is broken down, the signal for muscle contraction is reduced, resulting in muscle relaxation.
Both muscle relaxation and muscle contraction require ATP.

the ciliary muscle is the smooth muscle of the ciliary body
The medical term for delayed relaxation of a muscle after a strong contraction is myotonia. This condition is characterized by prolonged muscle stiffness or difficulty relaxing the muscle after it has been contracted. Myotonia can occur in conditions such as myotonic dystrophy or myotonia congenita.
Contraction or relaxation of muscle fibre, due to similar effect in sarcomere
contraction and relaxation
Skeletal muscle twitch is a single, brief contraction and relaxation cycle, whereas a tetanic contraction involves sustained, rapid repeated contractions without relaxation in between. Tetanic contractions occur when the muscle is stimulated at a high frequency, leading to a fused contraction.
