Vocabulary
What is the muscular system?
The muscular system comprises muscles that work with the skeletal system. If all of your muscles rested at once, you would collapse.
What is a flexor?
Flexors work in pairs with extensors. A flexor is a muscle that bends a part of the body. EX: Biceps Brachii.
Describe the hamstrings.
The hamstings are the flexor of the upper leg. It allows movement of the knee and lower leg.
What is the trapezius?
The trapezius is the muscle extending over your neck and upper back. It helps with rotation of the neck, back, and arms.
What is a strain?
A strain is when a muscle or tendon is overstretched or torn.
What is a muscle?
A muscle is a tissue in your body that helps produce movement. There are 3 types of muscle: skeletal, cardiac, and smooth muscle. Muscles often work in pairs (one bends part of the body and one extends).
What is an extensor?
An extensor works in a pair with a flexor. They extend a part of the body. EX: Triceps Brachii.
Where is the gastrocnemius?
The gastrocnemius is the largest calf muscle. It is located at the back of the lower leg.
Describe the Latissimus Dorsi
The lattisimus dorsi is the broadest muscle of the back. It allows rotation movement of the back.
What is tendonitis?
Tendonitis is a disease where a tendon becomes inflamed.
Describe skeletal muscle.
Skeletal muscle can be voluntary or involuntary. They attach to bones and pull on them to allow you to move.
What is a Tendon?
A tendon is a strand of tough connective tissue that connects skeletal muscles to your bones.
What are the gluteal muscles?
There are 3 gluteal muscles: The gluteus minimus 9the smallest), gluteus medius(beneath the gluteus maximus and the medium muscle), and gluteus maximus (the largest). They make up the buttock.
What is the pectoralis?
The pectoralis is the muscles of the chest. The largest is the pectoralis major. You can strengthen this by doing resistance exersises like push-ups and bench presses.
What are the dangers of anabolic steriods?
1) Can damage kidneys, liver, heart, and other organs.
2) Can cause high blood pressure.
3) Can cause bones to stop growing.
Describe cardiac muscle.
The cardiac muscle is found only in the heart. It is an involuntary muscle that pumps blood around the body.
What is resistance exercise?
Resistance exercise strengthens your muscles and teaches resistance. It also increases muscle size. EX:resistance bands, weights, push ups, squats, sit-ups.
Where are the deltoids?
The deltoid are your shoulder muscle that allow the movement of the arm. You can strengthen these muscles by doing resistance exercises like lifting weights above the head.
Describe the rectus abdominus.
The abdominals are located in the front of the abdomen. They help maintain posture, breathe, cough, and much more.
How does the muscular system work with the skeletal system to maintain homeostasis?
The muscular and skeletal systems work together to maintain homeostasis by allowing movement. Skeletal muscles pull on bones, allowing the bones to move. If this didn't happen, we would not get exercise resulting in very weak bones. This helps our body get stronger and move to do everyday functions.
Describe smooth muscle.
Smooth muscle lines the walls of blood vessels and is in the digestive tract. It helps food move.
What is aerobic exercise?
Aerobic exercise teaches endurance, increases muscle size, and strengthens the heart. EX: jogging, cycling, swimming, skating, walking.
What are the quadriceps?
The quadriceps are the exstensor of the upper leg.
What is the difference between the biceps brachii and triceps brachii?
The biceps brachii is the flexor of the upper arm, while the triceps brachii is the exstensor of the upper arm.
How does the muscular system work with the integumentary system to maintain homeostasis?
The muscular system works with the integumentary system to maintain homeostasis by regulating body temperature. when you are cold, muscle fibers in the dermis pull on the hair follicles, causing the hairs to stand up. The hair acts as a blanket and pulls in warm air. This helps keep your body warm, and if this did not happen, you could freeze to death.
