- 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.
What are the differences between skeletal and cardiac muscle?
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.
What are the differences between the three muscle types?
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. The smooth muscle tissue that forms organs like the stomach and bladder changes shape to facilitate bodily functions.
What do the 3 types of muscle have in common?
- Terminal of motor axon interfaces with muscle cell. ...
- Synaptic Cleft: Gap thru which transmitter diffuses.
What is the difference between skeletal smooth and cardiac muscle analysis questions?
What is the difference between skeletal, smooth, and cardiac muscle? Skeletal muscles – attached to your skeleton and tendons and are able to move at will or voluntary . ... Cardiac muscle – the heart, is an extremely dense strong tissue.
What is the strongest muscle in the human body?
The strongest muscle based on its weight is the masseter . With all muscles of the jaw working together it can close the teeth with a force as great as 55 pounds (25 kilograms) on the incisors or 200 pounds (90.7 kilograms) on the molars.
What are the classification of muscles?
- Skeletal Muscle. Skeletal muscle, attached to bones, is responsible for skeletal movements. ...
- Smooth Muscle. ...
- Cardiac Muscle.
What are the similarities and differences between the structure and function of skeletal smooth and cardiac muscle?
Cardiac muscle is also an involuntary muscle but is more akin in structure to skeletal muscle, and is found only in the heart. Cardiac and skeletal muscles are striated, in that they contain sarcomeres and are packed into highly regular, repeating arrangements of bundles; smooth muscle has neither attribute.
What are two key differences between cardiac muscle and skeletal muscle?
| Cardiac Muscle Skeletal Muscle | In heart only Attached to bones of the entire body | Length | Shorter Longer | Controlled by |
|---|
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 the smallest muscle in the body?
Stapedius muscle is termed to be the smallest skeletal muscle in human body, which has a major role in otology. Stapedius muscle is one of the intratympanic muscles for the regulation of sound.
What is the main organ of the muscular system?

How do muscles grow?
Muscle size increases when a person continually challenges the muscles to deal with higher levels of resistance or weight . This process is known as muscle hypertrophy. ... The body repairs damaged fibers by fusing them, which increases the mass and size of the muscles.
What structure is unique to cardiac muscle?
Unique to the cardiac muscle are a branching morphology and the presence of intercalated discs found between muscle fibers . The intercalated discs stain darkly and are oriented at right angles to the muscle fibers. They are often seen as zigzagging bands cutting across the muscle fibers.
What is the function of cardiac muscle?
12.1. 1.1 Cardiac muscle. Cardiac muscle tissue forms the muscle surrounding the heart. With the function of the muscle being to cause the mechanical motion of pumping blood throughout the rest of the body , unlike skeletal muscles, the movement is involuntary as to sustain life.
What is the shape of cardiac muscle?
A healthy adult cardiomyocyte has a cylindrical shape that is approximately 100μm long and 10-25μm in diameter. Cardiomyocyte hypertrophy occurs through sarcomerogenesis, the creation of new sarcomere units in the cell. During heart volume overload, cardiomyocytes grow through eccentric hypertrophy.
