Are most cardiac muscles controlled directly by the nervous system?

No, most cardiac muscles are not directly controlled by the nervous system. The cardiac muscles have their own intrinsic pacemaker called the sinoatrial (SA) node that generates electrical impulses and coordinates the contraction of the heart. While the nervous system can influence the rate and strength of the heart's contractions, it does not have direct control over the cardiac muscles.


What is the period of time called between the beginning of one heartbeat and the start of the next?

The period of time between the beginning of one heartbeat and the start of the next is known as the cardiac cycle. It consists of two phases: systole (contraction of the heart muscles) and diastole (relaxation of the heart muscles).

Are voluntarily controlled by skeletal or cardiac or smooth?

Voluntary muscles are controlled by the skeletal muscle system, while cardiac and smooth muscles are involuntary and regulated by the autonomic nervous system. Skeletal muscles are under conscious control for movement, posture, and facial expressions, while cardiac muscles control the heart's contractions and smooth muscles regulate internal organ functions.


Which two muscle types are controlled involuntarily?

Smooth muscles and cardiac muscles are controlled involuntarily - they are not under conscious control. Smooth muscles control functions such as digestion and blood vessel constriction, while cardiac muscles control the beating of the heart.


What are the muscles called that cannot be controlled?

There are some muscles in the body we cannot control: they are called involuntary muscles and cardiac muscles. Involuntary muscles are found in the digestive tract for example. Cardiac muscles are found in the heart. Neither these two muscle types are controlled. We can control what are called voluntary muscles which are the muscles that were used to move our bones.


What muscles move independently from our thoughts?

Muscles that move independently from our thoughts are primarily those controlled by the autonomic nervous system, such as smooth muscles and cardiac muscles. Smooth muscles are found in organs like the intestines and blood vessels, and they operate involuntarily to regulate functions like digestion and blood flow. Cardiac muscle, which makes up the heart, also contracts autonomously to maintain a rhythmic heartbeat without conscious control. These muscles function automatically to support vital bodily processes.
