Muscular system

3 types of muscle tissue

Cardiac, Smooth, and Skeletal

Describe physical characteristics of Skeletal muscle

skeletal muscle fiber is thin and cylindrical, striated, long and narrow,

How does Skeletal muscle move?

It moves under voluntary control, attached to connective tissue, contracts from the muscle across the joint and onto the bone

What is a tendon?

Fibrous connective tissue that connects muscle to bone

Characteristic of Smooth muscle

No striations, slower to contract and relax

Where can smooth muscle be found?

Digestive tract, in the walls of arteries respiratory tract, urinary tract, and reproductive tract.

Cardiac muscle

Contracts rhythmically and automatically in the heart to pump blood through heart chambers.

Examples of diseases in muscle tissue?

Muscle dystrophy, myasthenia gravis, ripped rotator cuff.

Medical devices used on the muscular system

ACL sets, arthroscopes, tenotomy sets
