What else can I help you with?
Are the lungs composed of smooth muscle?
No, the lungs are not composed of smooth muscle. They are made up of a spongy tissue called lung parenchyma, which includes air sacs and blood vessels. Smooth muscle is found in the walls of the airways leading to the lungs, called bronchioles.
Does the trachea have skeletal muscle?
No, the trachea does not have skeletal muscle. Instead, it is composed of smooth muscle, cartilage, and connective tissue. Smooth muscle allows for involuntary control of the trachea's diameter and airflow.
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.
Can you see sarcomeres in smooth muscle?
No, sarcomeres are not visible in smooth muscle. Smooth muscle lacks the organized sarcomere structure found in striated muscle, such as skeletal and cardiac muscle. Instead, smooth muscle has a more scattered arrangement of contractile proteins.
How does the contraction mechanism of smooth muscle compare to that of skeletal muscle and cardiac muscle?
Smooth muscle, skeletal muscle, and cardiac muscle all contract in response to signals from the nervous system or hormones. However, the contraction mechanism of smooth muscle is different from that of skeletal and cardiac muscle. Smooth muscle contracts more slowly and can sustain contractions for longer periods of time compared to skeletal and cardiac muscle. Additionally, smooth muscle does not have striations like skeletal and cardiac muscle, which gives it a more uniform appearance.
Smooth muscle is characterized by?
The smooth muscle is an involuntary, non-striated muscle. It is divided into two sub-groups: the single-unit and multiunit smooth muscle.
Which are the two major types of smooth muscle?
multiunit ans visceral
What kind of muscle tissue is piloerector muscle made of?
It's made out smooth muscle, of the multiunit variety, like the iris.
Where is smooth muscle and what are its functions?
Smooth muscles are an involuntary non-striated muscles. It is divided into two sub-groups; the Single unit (unitary) and multiunit smooth muscle Hope this helps! :)
What smooth muscles are controlled by autonomic nerves and hormones?
are multiunit muscles.single unit muscle
What type of muscle is found in the walls of hollow organs and in the walls of blood vessels?
multiunit smooth muscle are found in those areas and a few more.
Parts and functions of smooth muscle?
Smooth muscle cells contain filaments called actin and myosin that extend the lengths of the cells, but these filaments are organized differently than striated muscle. Smooth muscle cells lack striations and appear "smooth" under the microscope. There are two types of smooth muscle. They are multiunit and visceral. The multiunit are not found in sheets. This found in the irises of the eye and in blood vessels. They respond to nerve stimulation and some hormones. Visceral smooth muscles are found in sheets and they are found in hollow organs. They stimulate each other forming waves. These don't tire easily and do not lose pressure when distended.
Muscle sphincters are composed of what two types of muscle fibers?
Smooth Muscle Fiber
What is Non-striated involuntary muscle type?
its Smooth muscle is an involuntary non-striated muscle, so-called because it has no sarcomeres and therefore no striations (bands or stripes). It is divided into two subgroups, single-unit and multiunit smooth muscle. Within single-unit muscle, the whole bundle or sheet of smooth muscle cells contracts as a syncytium. lol i know more than u
The middle lining of the stomach is composed of this type of muscle tissue?
smooth muscle
What muscles are in the stomach?
The stomach is composed of smooth muscle (as opposed to skeletal or cardiac muscle).
Are the lungs composed of smooth muscle?
No, the lungs are not composed of smooth muscle. They are made up of a spongy tissue called lung parenchyma, which includes air sacs and blood vessels. Smooth muscle is found in the walls of the airways leading to the lungs, called bronchioles.
