Skeletal System
These bones protect the heart and the lungs.
What are the ribs?
The heart is called an involuntary muscle because of this
What is never stops contracting to pump blood through out the body?
These structures connect bone to bone, providing joint stability.
What is a ligament?
This is can be found in the nose and the ear but its not muscle or bone.
What is cartilage?
Muscle fibers use this molecule as their primary energy source and rely on this gas for efficient energy production.
What are ATP and oxygen?
Name the three bones of the arm
what are humerus, ulna and radius
This muscle type is found in the walls of hollow organs and is involuntary.
What is smooth muscle?
This occurs when a muscle loses its ability to contract effectively due to prolonged activity or insufficient energy.
What is muscle fatigue?
Some call this bone the knee.
What is the Patella?
Strongest type of muscle! Works 24 hours a day and never fatigues because it contains MANY mitochondria.
What is cardiac muscle?
Name the three bones of the leg.
What are the tibia, fibula, and femur.
This type of muscle tissue lacks striations.
What is smooth muscle.
These muscles are striated and have many nuclei.
What are skeletal muscles?
This part of the skeleton includes the bones of the limbs, as well as the pectoral and pelvic girdles.
What is the appendicular skeleton?
Also known as myocardiocytes, these specialized cells are striated, branched, and connected by intercalated discs to allow synchronized contraction of the heart.
what are cardiac muscle cells?
The spongy tissue inside bone that produces blood cells.
What is bone marrow.
These are the three types of muscles.
What are the cardiac, smooth and skeletal muscles?
This muscle is attached to your bones and allows you to move and have total control of your movement.
What is the skeletal muscle?
These paired cranial bones form the sides and roof of the skull.
What is a parietal bone?
These two proteins interact to cause muscle contraction, with one forming thick filaments and the other forming thin filaments.
What are actin and myosin?
What includes the skull, spine and ribcage.
What is the axial skeleton?
This structure connects muscle to bone
Tendon
This compound builds up in muscles during anaerobic respiration, contributing to muscle fatigue.
what is lactic acid?
I am a small, triangular bone at the base of the spine. I am often referred to as the "tailbone" and can be injured if you fall on your back.
What is the coccyx?
These chemical messengers are released by nerves in response to electrochemical signals from the brain to trigger muscle contraction.
What is a neurotransmitter?
