Muscle Tissue Characteristics and Functions

Muscle tissue consists of specialized cells capable of contraction, enabling movement. There are three types: skeletal, cardiac, and smooth. Skeletal muscle, attached to bones, is voluntary and striated. Cardiac muscle, found in the heart, is involuntary, striated, and connected by intercalated discs. Smooth muscle, in hollow organs, is involuntary and non-striated, facilitating material movement.

What is the primary function of muscle tissue?

• To transport nutrients

• To store energy

• To generate force and produce movement

• To protect internal organs

Which type of muscle tissue is responsible for voluntary movements?

• Smooth muscle tissue

• Skeletal muscle tissue

• Cardiac muscle tissue

• None of the above

What characteristic is unique to skeletal muscle fibers?

• They are multinucleated

• They are short and branched

• They lack striations

• They are found in the heart

How are cardiac muscle cells connected to each other?

• By synapses

• By ligaments

• By intercalated discs

• By tendons

Where is cardiac muscle tissue located?

• In the walls of the intestines

• In the walls of blood vessels

• In the walls of the heart

• In the walls of the stomach

Which muscle tissue type is found in the walls of hollow organs?

• Cardiac muscle tissue

• None of the above

• Skeletal muscle tissue

• Smooth muscle tissue

What is a defining feature of smooth muscle cells?

• They have striations

• They are voluntary

• They are multinucleated

• They are short and tapered
