What is the structure of cardiac muscle?
Cardiac muscle is striated muscle that is present only in the heart.
Cardiac muscle fibers have a single nucleus, are branched, and joined to one another by intercalated discs that contain gap junctions for depolarization between cells and desmosomes to hold the fibers together when the heart contracts..
What is the main function of smooth muscle?
The primary function of smooth muscle is contraction. Smooth muscle consists of two types: single-unit and multi-unit. Single-unit smooth muscle consists of multiple cells connected through connexins that can become stimulated in a synchronous pattern from only one synaptic input.
What is a type of muscle?
There are three types of muscle, skeletal or striated, cardiac, and smooth. Muscle action can be classified as being either voluntary or involuntary. Cardiac and smooth muscles contract without conscious thought and are termed involuntary, whereas the skeletal muscles contract upon command.
What is cardiac muscle example?
1 Answer. Cardiac muscle is found only in the heart. The word cardiac is an adjective specific to the heart, for example cardiac arrest is a heart attack.
Which type of muscle works automatically?
Smooth musclesSmooth muscle is found in the walls of hollow organs like your intestines and stomach. They work automatically without you being aware of them. Smooth muscles are involved in many ‘housekeeping’ functions of the body.
Which is not a function of the muscular system?
Answer. PRODUCTION OF BLOOD CELLS is not a function of the muscular system.
What are the characteristics of muscle tissue?
All muscle tissues have 4 characteristics in common:excitability.contractility.extensibility – they can be stretched.elasticity – they return to normal length after stretching.
What characteristic is not descriptive of cardiac muscle tissue quizlet?
Both skeletal and cardiac muscle tissues consist of striated muscle cells. What characteristic is NOT descriptive of cardiac muscle tissue? Sarcoplasmic reticulum.
What are the 4 characteristics of cardiac muscle tissue?
Cardiac muscle cells are found only in the heart, and are specialized to pump blood powerfully and efficiently throughout our entire lifetime. Four characteristics define cardiac muscle tissue cells: they are involuntary and intrinsically controlled, striated, branched, and single nucleated.
What are the distinguishing characteristics of heart muscle tissue?
Cardiac muscle is only found in the heart. Its fibers are longer than they are wide, and they are striated, like skeletal muscle fibers. But, unlike skeletal muscle fibers, cardiac muscle fibers have distinct ends to them, called intercalated discs. These are dark lines that run from one side of the fiber to the other.
Is another name for muscle cell?
myocytesMuscle cells, commonly known as myocytes, are the cells that make up muscle tissue. There are 3 types of muscle cells in the human body; cardiac, skeletal, and smooth. Skeletal muscle cells are long, cylindrical, multi-nucleated and striated.
What is special about tissue present in heart?
Answer. Cardiac muscle is specialized tissue that is found only in the heart. It has characteristics similar to both smooth and skeletal muscle tissue, as well as specialized properties, that allow it to function with fast but sustained contractions, rapid conduction and coordinated movement.
What characteristic is seen in cardiac muscle but not in smooth muscle?
Muscle Types: Cardiac and skeletal muscle are both striated in appearance, while smooth muscle is not. Both cardiac and smooth muscle are involuntary while skeletal muscle is voluntary.
What is the basic function of all muscle tissue?
Muscle is one of the four primary tissue types of the body, and the body contains three types of muscle tissue: skeletal muscle, cardiac muscle, and smooth muscle (Figure 15.2). The primary function of all muscle tissue is movement.
What is the main function of cardiac muscle?
Cardiac muscle tissue works to keep your heart pumping through involuntary movements. This is one feature that differentiates it from skeletal muscle tissue, which you can control. It does this through specialized cells called pacemaker cells. These control the contractions of your heart.
What are the five properties of muscle tissue?
Terms in this set (5)Excitability- can be stimulated by chemical signals, nerves and stretch.Conductivity- the signal for a muscle to contract is spread from the point of stimulation throughout the entire muscle.Contractility- ability of the muscle to shorten.Extensibility- … Elasticity-
What kind of muscle tissue is Multinucleated?
Skeletal muscle fibers are cylindrical, multinucleated, striated, and under voluntary control. Smooth muscle cells are spindle shaped, have a single, centrally located nucleus, and lack striations. They are called involuntary muscles.
What makes cardiac muscle cells unique?
Like skeletal muscle, cardiac muscle cells are striated due to a similar arrangement of contractile proteins. Unique to the cardiac muscle are a branching morphology and the presence of intercalated discs found between muscle fibers.
What are the 5 major properties of the muscular system?
There are 5 major properties to the muscular system.Excitable or Irritable.Contractible.Extensible.Elasticity.Adaptability.Sep 14, 2015
What are three different types of muscle tissue?
The 3 types of muscle tissue are cardiac, smooth, and skeletal. Cardiac muscle cells are located in the walls of the heart, appear striated, and are under involuntary control.
