What else can I help you with?
True or false smooth muscle fibers are located in small skeletal muscles?
smooth muscle fibers are located in small skeletal muscle
Do skeletal muscle fibers contain sarcomeres whereas smooth muscle fibers do not?
Yes, skeletal muscle fibers contain sarcomeres, which are the repeating units responsible for muscle contractions. In contrast, smooth muscle fibers do not have sarcomeres in the same organized structure but still have contractile proteins.
Do smooth muscle cells posses central nuclei but lack striations?
Smooth muscle is not striated, hence the name smooth muscle.nonotcardiac muscle
Smooth muscle is found inside your organs and it contracts very quickly?
True
Is A precapillary sphincter a cuff of smooth muscle that regulates the flow of blood into the capillaries?
true
Does most disorders of the autonomic nervous system refeclt abnormalities of smooth muscle control?
True
The esophagus contains both smooth and skeletal muscle fibers?
The esophagus has two types of muscles. The upper third of the esophagus is composed of striated muscles, while the lower third contain smooth muscles. The muscles in the middle are a mixture of both striated and smooth.
What type of muscle tissue is in the esophagus?
Smooth muscles make up most of the esophagus, but the upper portion also contains some voluntary or skeletal muscle. The muscles move in a wave like pattern to move food down into the stomach through a process called "peristalsis". At the distal end is the lower esophageal sphincter, a ring of smooth muscle that controls movement of food between the stomach and esophagus.
What statement is true regarding the structure of the school system in the US?
It explains the reasons why the Constitution was written
Is it true that ATP id required for muscle contraction but not for muscle relaxation?
true
Is it true The more a muscle shortens during a contraction then the greater the power of the muscle?
No it is not true.
Is it true that arteries control the amount of blood that different organs receive?
True. Arteries are responsible for bringing oxygenated blood to the body. The smooth muscle surrounding the arteries can expand or contract causing more or less blood to flow through to the organs.
