Physiotherapy Unit 7 - Muscular System Muscular System ( voluntary Muscle Types and Actions There are three types of muscles. They include cardiac muscle, skeletal muscle, and smooth muscle. Cardiac muscles are found in the walls of the heart. They are tendon involuntary, with repeating sarcomeres. Cardiac muscles —' function like other body tissues. They use blood to deliver oxygen and nutrients. Among skeletal muscles, voluntary contractions produce movement. Contractions create tension, which shortens muscles. Tendons and ligaments also assist in movement. Skeletal muscles have numerous fibers. These include red and white fibers. They also include twitch fibers. Fast twitch fibers produce higher action potential. Smooth muscle is present in the vital organs. In the digestive system, these muscles help with digestion.

What is the function of skeletal muscles? Skeletal muscles are voluntary and assist in physical movements. These muscles contract when we move our limbs. 1 What is the main idea of the passage?

Then, take roles and act it out USE LANGUAGE SUCH AS: What are the differences between...? How many different types of... are there? I don't quite understand how... Student A: You are a student. Talk to Smdent B about: • types of muscles • voluntary a^d involuntary contractions • the location! s) of certain muscles Student B: You are a professor. Talk to Student A about how to distinguish between types of muscles. What are the differences between types of muscles? They include skeletal muscles, smooth muscles, and cardiac muscles. And the others produce involuntary movements, right?] I don't quite understand how we distinguish between those movements. What are the differences between types of muscles? They include skeletal muscles, smooth muscles, and cardiac muscles. And the others produce involuntary movements, right' I don't quite understand how we distinguish between those movements. A: B: Well, please tell me: how many different types of muscles are there? A: Three. B: Very good. Skeletal muscles are different from the other types because they produce voluntary contractions. A: B: Yes. that's right. A: So. when we swallow, is that action voluntary or involuntary? B: Swallowing, though it occurs within the digestive system, is voluntary. We don't have to swallow. Movements that occur in our intestines when we digest are involuntary. Muscle Types and Actions (Quick Facts) 1 There are three types of muscles.
