What muscle tissue is responsible for voluntary movement?
Which muscle tissue is voluntary and involuntary?
What tissue is voluntary and involuntary?
Skeletal muscle is voluntary and responds to conscious stimuli. The cells are striated and multinucleated appearing as long, unbranched cylinders. Cardiac muscle is involuntary and found only in the heart. Each cell is striated with a single nucleus and they attach to one another to form long fibers.
Where are involuntary muscle tissue located?
Cardiac muscle cells are located in the walls of the heart, appear striated, and are under involuntary control. Smooth muscle fibers are located in walls of hollow visceral organs, except the heart, appear spindle-shaped, and are also under involuntary control.
What is muscular tissue and its function?
Muscle tissue consists of elongated cells also called as muscle fibers. This tissue is responsible for movements in our body. Muscles contain special proteins called contractile protein which contract and relax to cause movement. Muscle tissues vary with function and location in the body.
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 is an example of muscle tissue?
1) smooth muscle. 3) Cardiac muscle. It can be found in the walls of the heart. Cardiac muscle tissues in heart contract to pump blood to all parts of the body.
What type of muscle tissue is attached to bones?
Which type of muscle tissue is Multinucleated quizlet?
What does all muscle tissue have in common?
All muscle tissues have 4 characteristics in common: excitability. contractility. extensibility – they can be stretched.
What do the three muscle tissues have in common?
All three muscle tissues have some properties in common; they all exhibit a quality called excitability as their plasma membranes can change their electrical states (from polarized to depolarized) and send an electrical wave called an action potential along the entire length of the membrane.
What organs contain smooth muscle tissue?
Smooth muscle (so-named because the cells do not have striations) is present in the walls of hollow organs like the urinary bladder, uterus, stomach, intestines, and in the walls of passageways, such as the arteries and veins of the circulatory system, and the tracts of the respiratory, urinary, and reproductive …
What disease affects the smooth muscle?
Multisystemic smooth muscle dysfunction syndrome is a rare, genetic, vascular disease characterized by congenital dysfunction of smooth muscle throughout the body, manifesting with cerebrovascular disease, aortic anomalies, intestinal hypoperistalsis, hypotonic bladder, and pulmonary hypertension.
What is the function of smooth muscle tissue?
Smooth 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. The muscular walls of your intestines contract to push food through your body.
What are the two types of smooth muscle tissue?
Smooth muscle is organized in two ways: as single-unit smooth muscle, which is much more common; and as multiunit smooth muscle. The two types have different locations in the body and have different characteristics.
What are the characteristics of smooth muscle tissue?
Four characteristics define smooth muscle tissue cells: they are involuntarily controlled, not striated, not branched, and singly nucleated. The unconscious regions of the brain control visceral muscle through the autonomic and enteric nervous systems.
What is the definition of smooth muscle tissue?
Smooth muscle, also called involuntary muscle, muscle that shows no cross stripes under microscopic magnification. It consists of narrow spindle-shaped cells with a single, centrally located nucleus. Smooth muscle tissue, unlike striated muscle, contracts slowly and automatically.
Which muscles are known as the smooth muscles?

What are the four major functional characteristics of muscle tissue?
Muscle has four functional characteristics: contractility, excitability, extensibility, and clasticity. elasticity 2. The capacity to respond to a stimulus.
What is unique about smooth muscle?
Smooth muscles are unique in their largely involuntary response, and in their structure. Smooth muscles have a much stronger ability to contract than skeletal muscles, and are able to maintain contraction longer.
What are the 3 muscle types?
The three main types of muscle include:
- Skeletal muscle – the specialised tissue that is attached to bones and allows movement.
- Smooth muscle – located in various internal structures including the digestive tract, uterus and blood vessels such as arteries.
- Cardiac muscle – the muscle specific to the heart.
Which type of muscle is voluntary?
What is muscular tissue and its types?
In the muscular system, muscle tissue is categorized into three distinct types: skeletal, cardiac, and smooth. Each type of muscle tissue in the human body has a unique structure and a specific role. Skeletal muscle moves bones and other structures. Cardiac muscle contracts the heart to pump blood.
What is Class 9 muscle tissue?
Muscular tissue consists of elongated cells, also called muscle fibres. This tissue is responsible for movement in our body. Main function of muscular tissues is to provide movement to the body. Muscles contain special proteins called contractile proteins, which contract and relax to cause movement.
What is tissue and its types?
Tissues are groups of cells that have a similar structure and act together to perform a specific function. There are four different types of tissues in animals: connective, muscle, nervous, and epithelial.
