What muscular system is made up of cell that are long thin and pointed?

The muscle system made up of cells that are long, thin, and pointed is the cardiac muscle system. Cardiac muscle cells are unique in structure and function, as they are found in the heart and have a branching, interconnected appearance. These cells contract rhythmically to pump blood throughout the body.


What is a very long and contracting cell?

A very long and contracting cell is typically a muscle cell, specifically a skeletal muscle fiber. These cells can extend several centimeters in length and are capable of contracting to facilitate movement. Their unique structure, composed of elongated myofibrils, allows for rapid and powerful contractions essential for bodily functions. Additionally, cardiac muscle cells, which are also long and contract, play a crucial role in pumping blood throughout the heart.


Is Heart made up of striated or non striated muscles?

Heart muscle is striated but not in the same way that skeletal muscle is. Cardiac muscle is a type of involuntary striated muscle found only in the walls of the heart.Cardiac and skeletal muscle are similar in that both appear to be striated in that they contain sarcomeres. In striated muscle, such as skeletal and cardiac muscle, the actin and myosin filaments each have a specific and constant length on the order of a few micrometers, far less than the length of the elongated muscle cell (a few millimeters in the case of human skeletal muscle cells).The filaments are organized into repeated subunits along the length. These subunits are called sarcomeres. The sarcomeres are what give skeletal and cardiac muscles their striated appearance of narrow dark and light bands, because of the parallel arrangement of the actin and myosin filaments.However, cardiac muscle has unique features relative to skeletal muscle. For one, the myocytes are much shorter and are narrower than the skeletal muscle cells, being about 0.1 millimeters long and 0.02 millimeters wide .Furthermore, while skeletal muscles are arranged in regular, parallel bundles, cardiac muscle connects at branching, irregular angles.Anatomically, the muscle fibers are typically branched like a tree branch. In addition, cardiac muscle fibers connect to other cardiac muscle fibers through intercalcated discs and form the appearance of a syncytium (continuous cellular material).These intercalcated discs, which appear as irregularly-spaced dark bands between myocytes, are a unique and prominent feature of cardiac muscle .


When was the muscle cell discovered?

The first man to witness a live cell under a microscope was Anton Van Leeuwenhoek in 1674 AD


A skeletal muscle cell is also known as a?

A skeletal muscle is also known as a striated muscle. When viewed under polarized light or stained with an indicator, alternating stripes of light and dark are visible.

Can muscle cells form cardiac and skeletal muscles?

Skeletal muscle cells are much bigger than cardiac muscle cells. Skeletal muscle fibres are up to 100 micrometers in diameter and several centimeters long while cardiac myocytes are about 15 micrometers in diameter and about 100 micrometers long.


What does it mean if a muscle is striated?

Striated muscle includes cardiac muscle and skeletal muscle. Cardiac muscle is found only in the heart. Skeletal muscle is between bones and is voluntarily controlled. Examples of skeletal muscle are the sternoclydomastoid, biceps, obicularis oris, rectus femoris, etc.


How long can cardiac muscle be deprived of oxygen before the cardiac muscle cells start to die?

5 minutes


What is The type of muscle tissue forming the heart muscle?

Cardiac which is involuntary and striated muscle tissueInvoluntaryThe heart is composed of cardiac muscle tissue. This type of tissue contracts rhythmically without external stimulus. Each cell will have it's own pulse until it comes into contact with another cardiac muscle cell, then they will synchronize their movements with each other. Over all the heart automatically responds to your bodies need for increased oxygen by speeding up, then slowing back down as the need is satisfied.Cardiac muscle.Cardiac muscle tissue.cardiac muscle.The muscle in the heart is cardiac muscle.

They are known as cardiac muslces. The heart is an organ as well as a muscle.cardiac muscleThe heart is made of cardiac muscle. It is involuntary muscle. That means that a person can not make it work by thinking about it. There are two other types. One is smooth muscle, which has no visible striations and it also involuntary. This is found in arteries and the walls of the digestive, urinary, other hollow organs and respiratory tracts and the irises of the eye. The last type is voluntary muscles such as found int muscles that move your bones. The heart is a MUSCLE.


Which cell types has the lowest proliferative ability?

Nonrenewing or permanent cells. They have no proliferative capacity. They never seem to decide. Have a long life span and live in protected environments. Eg. Neurons, cardiac muscle cells


The difference between the structure of cardiac muscle and skeletal muscle?

One key difference between cardiac and skeletal muscles is that skeletal muscles are controlled by the nervous system, while cardiac muscles move involuntarily. In addition, cardiac muscles are only found in the heart, while skeletal muscles are found throughout the entire body.

What are the muscles cells called?

Muscle cells are called muscle fibers or myocytes. They are specialized cells that make up the three types of muscle tissue: skeletal, cardiac, and smooth muscle. Skeletal muscle fibers are long and striated, cardiac muscle cells are branched and striated, while smooth muscle cells are non-striated and spindle-shaped. Each type of muscle cell has distinct functions suited to its specific location and role in the body.


What causes skeletal and cardiac muscles to appear striated?

The myofibres cause skeletal and cardiac muscles to appear striated because they are cyndrical and long, extending across the entire surface of the muscle.


Why does the muscle cell have a long shape?

The cell is long because the , muscle needs to stretch and contract when you use that muscle. Therefore it needs to be long in order to stretch.

Do cardiac muscle cells are long cylindrical?

Cardiac muscle cells, known as cardiomyocytes, are not long and cylindrical like skeletal muscle cells. Instead, they are typically shorter and branched, which allows them to connect with each other at intercalated discs. These specialized connections enable synchronized contractions essential for effective heart function. Unlike skeletal muscle, cardiac muscle cells also contain a single nucleus and are involuntary in nature.
