Muscular System Flashcards
(24 cards)
What is the primary function of the muscular system?
The primary functions include movement, heat production, maintaining posture, protection, and assisting internal organs.
How do muscles attach to bones?
Muscles attach to bones through connective tissue.
What controls muscle action?
Muscle action is controlled by the nervous system.
What are the two types of muscle control?
The two types are voluntary (under your control) and involuntary (not under your control).
What are the three types of muscles?
The three types of muscles are cardiac, smooth, and skeletal.
What type of muscle movement is cardiac muscle?
Involuntary
What type of muscle is smooth muscle?
Involuntary
Works to move materials through the body
Where does smooth muscle work in the body?
Digestive tract and blood vessels
What type of muscle is skeletal muscle?
Skeletal muscle is voluntary.
What is the primary function of skeletal muscle?
Skeletal muscle is attached to bones for movement and helps protect inner organs.
What is a flexor?
A flexor bends part of the body.
Examples include biceps and hamstrings.
What is an extensor?
An extensor straightens part of the body.
Examples include triceps and quadriceps.
What is resistance training?
Resistance training involves working against weight or an object to increase strength.
What are some examples of resistance training?
Examples include weight-lifting, push-ups, and sit-ups.
What is aerobic exercise?
Aerobic exercise is steady, moderately intense activity that increases endurance.
What are some examples of aerobic exercise?
Examples include running, dancing, and jumping jacks.
What is a muscle strain?
A muscle strain occurs when a muscle or tendon is overstretched or torn.
What is tendonitis?
Tendonitis is the inflammation of tendons from too much exercise and not enough rest.
What are anabolic steroids?
Anabolic steroids make muscles stronger but have negative side effects.
What are some negative side effects of anabolic steroids?
Negative side effects include long-term health problems, damage to heart, liver, and kidneys, high blood pressure, and potential stunted bone growth if taken before skeletal maturity.
What tissues are muscles made out of?
Muscle and connective tissue
