Muscular System Flashcards
The two types of involuntary muscles (unconscious control)
Smooth and Cardiac
Which type of muscle is this?
Cardiac Muscle
Semi-striped muscles with some branching
Cardiac
Which type of muscle is this?
Smooth Muscle
Type of muscle cell that has only one nucleus
Cardiac
The strength of muscle contraction is controlled by
The number of muscle cells activated
Which type of muscle has striations? (stripes)
Skeletal
What are the two types of filaments?
Thick filaments - myosin Thin filaments - actin
This type of muscle contracts rapidly, and with great force
Skeletal
Which type of muscle is this?
Skeletal Muscle
Found in the stomach, blood vessels, and intestine
Smooth Muscles
The main functions of the muscular system are
Producing movement, maintaining posture, stabilizing joints, and generating heat
Muscles are slow to contract
Smooth Muscles
Found only in the heart
Cardiac
Sliding filament theory explains how
The thick and thin filaments within the muscle past one another, shortening the entire length of the muscle
