involuntary muscles, where are they found and what do they do?

Answer 1

Involuntary muscles are smooth, uninucleated, non-branching muscles that are not directly controllable at will. These include the radially arranged iris muscles, the digestive system, reproductive system, major blood vessels, the skin and internal organs, and are all controlled by the autonomic nervous systemThese muscles are not as free as the voluntary muscles such as your arms legs, fingers, etc..

The cardiac muscle in heart can be called an involuntary muscle, although it may be classified separately due to its structural differences. it is controlled by nerve impulses produced by a natural pacemaker called the sinoatrial node, the rate of which is controlled by the autonomic nervous system. smooth muscles are found in the digestive system, reproductive system, major blood vessels, the skin and internal organs, and is also controlled by the autonomic nervous system.

Skeletal muscle is under conscious control and is, therefore, voluntary muscle.

Answer 2

They are in and around various organs. They do things like let you breathe, pump blood (the heart is an involuntary muscle), and work food through your digestive tract.

Answer 3

Involuntary muscles are muscles that move without you thinking about it. These are found in your digestion system (stomach and intestine) and also your heart.

Answer 4

I assume you didn't mean "involentary muscle movement or spasms" in which case the heart is the most prominent involentary muscle in the body. The digestive tract also has numurous muscles that move food and waste products into and out of the body. The diaphram is semi-involentary, in that it allows you to breath even when you are unconcious, yet allows you to hold your breath if you want to. The upper and lower duodenum of the stomach are one-way valves that operate independently of concious thought, that allow food into and out of the stomach at the correct time as well.

Answer 5

Involunary muscles are basically the ones you can NOT flex. Your heart and your intestines are good examples of these. They are designed to keep moving no matter what you're doing. It's a different type of muscle tissue, too. It is meant for squeezing rather than for contracting, like your bicep for instance, which is a voluntary muscle.

Answer 6

an involuntary muscle is any muscle you cannot control, an example is your heart, it does its own thing, you cant tell it to start or stop

Answer 7

muscles that are innervated without control-heart, diaphragm, smooth muscle tissue, such as the lining of the esophagus.

gotta love people that can look it up and copy and paste right? my answer was from knowledge learned while being a kinesiology student.

Answer 8

Brain - thinking
Heart - beating/pumping blood

thoes are the only 2 I remember

Answer 9

heart - digestive system ( all muscles you can't control as in start and stop )

Answer 10

The main one is the heart, another one is your diaphram. it is a muscle that you have no contol over.
