Among the scientific questions that you may encounter in any of the competitions is muscles that are not striated, are the muscles the answer? So you will need to have a fair amount of information in this regard.. Here is the correct answer below.
Muscles that are not striated what are they?
It is common knowledge that human body It contains many muscles of different types.. which is the most widespread throughout the body, as it constitutes the equivalent of 40% of its total mass.. It is responsible for movement and balance as well.
As for the answer Muscles that are not striated are the muscles the answer? It is a smooth muscle, and it also represents those involuntary muscles in the human body.. Therefore, it controls the subconscious areas of the brain, and depends on the nervous system.
From here we point out that the most important examples of this type of muscle are: Gastrointestinal muscles And the respiratory system.. Also, this type of muscle has many advantages and tasks that it performs.
It is worth noting that the functions of these muscles are the ability to move and move .. as well as stability through contraction and diastole, and also work to participate in the blood circulation that takes place inside the body .. as well as maintaining the position of the body and breathing, and also participates in Digestion Process.

Types of muscles in the human body
Within the framework of recognizing Muscles that are not striated are the muscles the answer? It was necessary to identify the types of muscles that are included in the human body.. which we will learn about through the following:
-
smooth muscle:
Muscles that consist of smooth muscle cell sheets or filaments..which most likely contain fibers composed of myosin and actin. In addition, they are contracted by certain stimuli..and then ADP is released through myosin..It depends on the amount of production on the intensity of stimuli; This helps the gradual contraction of smooth muscles. -
skeletal muscle:
They are those muscles that are also known as voluntary muscles.. They are one of the most common types in the human body, as they are characterized by an appearance dominated by lines and intersections with long and thin multi-nucleated fibers.. They have a regular shape of fine white and red lines, and from here we point out that they are characterized by From the rest of the other types that it is subject to voluntary movement, so the skeletal muscles are connected to the bones through tendons; This results in movement in different parts of the body. -
heart muscle:
Or the cardiac muscle is the muscle in the heart that works to pump blood… through the blood vessels connected to it. Hence, we note that it is characterized by being specific and organized in sarcomeres… However, it is characterized by the same organization in the skeletal muscle domains; Because it has only one nucleus and fibers that are shorter in length.. ADP is also produced in the heart muscle.. This is due to the presence of many mitochondria and myoglobin in the fibres. -
involuntary muscles:
They are those muscles that are difficult to control.. They work throughout the day inside the body, in addition to working to pump blood into the blood vessels.. Hence we point out that they also help to move food through the alimentary canal.. It should be noted that It is usually found in the walls of the digestive system and blood vessels, as well as in the bronchi, uterus and bladder.. Although it consists of striated muscle fibers, it does not have enough smoothness.. Hence we point out that it belongs primarily to the smooth muscle group, It also includes the cardiac muscles.

So here we have finished identifying the answer to the question of muscles that are not striated, are muscles the answer? Since it is one of the questions that you may encounter in some scientific competitions.. which you need to have information in this regard and focus.
