Muscle Types

The video tutorial explores the three types of muscles: cardiac, smooth, and skeletal. Cardiac muscles, found in the heart, are unique for their endurance but are sensitive to oxygen deprivation. Smooth muscles, located in blood vessels and organs, contract slowly and are involuntary. Skeletal muscles, responsible for voluntary movements, are striated and work with the skeleton. All muscle tissues are composed of specialized cells, connective tissue, nerve fibers, and blood vessels.

What is the primary function of all muscle cells?

• To store energy

• To contract

• To provide structural support

• To produce hormones

Where are cardiac muscles exclusively found?

• In the lungs

• In the stomach

• In the heart

• In the intestines

What is a unique feature of cardiac muscle?

• It can regenerate quickly

• It does not fatigue

• It is found in the brain

• It is under voluntary control

Which type of muscle is found in the walls of blood vessels?

• Smooth muscle

• Connective tissue

• Skeletal muscle

• Cardiac muscle

What type of muscle is responsible for voluntary movements?

• Cardiac muscle

• Smooth muscle

• Skeletal muscle

• Involuntary muscle
