HST-AP Introduction to the Muscular System

This video provides an overview of the muscular system, covering its main functions, properties, types of muscle movements, and types of muscles. It explains how muscles work with the nervous system to enable movement and discusses supportive structures like tendons and fascia. The video concludes with a brief mention of further study topics, such as major muscle groups and common diseases.

What is the primary purpose of the muscular system?

• To provide movement for the body

• To produce hormones

• To protect internal organs

• To regulate body temperature

Which property of muscles allows them to return to their original shape after being stretched?

• Elasticity

• Contractility

• Adaptability

• Excitability

Which muscle movement involves moving a body part toward the midline?

• Extension

• Flexion

• Adduction

• Abduction

Which type of muscle is responsible for circulating blood in the body?

• Cardiac muscle

• Smooth muscle

• Visceral muscle

• Skeletal muscle

Which type of muscle is classified as voluntary?

• Cardiac muscle

• Visceral muscle

• Smooth muscle

• Skeletal muscle

What is the role of tendons in the muscular system?

• To attach muscles to bones

• To protect muscles from damage

• To provide nutrients to muscles

• To connect muscles to other muscles

What happens to skeletal muscles if communication from the nervous system is severed?

• They become stronger

• They enter a state of paralysis

• They produce more movement

• They start to regenerate
