muscles
There more thin filaments than thick filaments in smooth muscle. The ratio is of the thin to thick filaments in the smooth muscle is approximately 15:1.
kidneys, stomach, intestines, bladder, the eyes, the walls of blood vessels. Smooth muscles that are sometimes called visceral muscles. They are thin muscles that look like spindles. They can be found in your skin and your blood vessels and your organs inside your body.
What everyone calls the abs are thin muscles of the body.
Fascia is the connective tissue that forms thin layers between muscles in the body. It provides support and helps separate and compartmentalize muscles to allow for smooth movement and function. Dysfunction or restrictions in the fascia can lead to pain and limited mobility.
Involuntary muscles are muscles that are not controllable consciously, and instead contract due to unconscious impulses sent by the autonomic nervous system or certain specialized cells or hormones. Both smooth muscle and cardiac muscle can be classified as involuntary muscles. Smooth muscle is comprised of spindle-shaped cells that have no striations and is found in numerous locations throughout the human body. Cardiac muscle is striated rather than smooth, and is found only within the walls of the heart. Smooth muscles are involuntary muscles composed of thick and thin protein filaments that are homologous to the organelles known as myofibrils found in skeletal muscles. The thin filaments are composed of a globular protein called actin, while the thick ones are made up of a motor protein called myosin. Smooth muscles require extracellular calcium ions to contract: the ions activate a nucleotide called Adenosine triphosphate (ATP), which then activates the myosin filaments. The myosin filaments attach to the actin filaments in a process known as the crossbridge cycle, which causes the thick and thin filaments to slide over each other and contract. When the myosin filaments release the actin filaments, the muscle relaxes.

Actin. Myosin are the thin ones.... it's actually the reverseThe thin filaments are composed primarily by the protein Actin.The thick filaments are composed primarily of the protein Myosin.
Actin (thin myofilament), myosin (thick myofilament), calcium, and ATP (energy).
A thin atmosphere is thin and a thick atmosphere is thick
The name given to contracting units of muscle fibers is sarcomeres. Sarcomeres are the basic functional units of skeletal muscles and they contain overlapping thick and thin filaments that slide past each other during muscle contraction.
concave lense is a piece of smooth glass that is thick from the edges and thin from centre and is used to diverge light rays.
