What attaches muscles to bones?
Tendons
What muscle is on the back of your arm?

branched, interconnected cells called cardiomyocytes, which contain a single nucleus, are striated due to organized sarcomeres, and are connected by specialized junctions called intercalated discs that contain gap junctions and desmosomes
What muscle disease is a nervous system disease that weakens muscles and impacts physical function?
Amyotrophic lateral sclerosis (ALS)
What special cells are muscles made out of?
Muscle fibers
What muscle is on the front of your thigh?

What is the function of the smooth muscle?
to contract and relax, allowing for the involuntary movement and regulation of internal organs like the stomach, bladder, blood vessels, and airways, by changing their shape and diameter to control the flow of substances through them
What is the structure of the bicep?
two distinct heads: a long head originating from the supraglenoid tubercle of the scapula, and a short head originating from the coracoid process of the scapula
Myositis
Most of the heat produced in your body comes from what?
Muscle contraction
What muscle is on the back of your calf?
Gastrocnemius
What is the function of the cardiac muscle?
to contract and relax rhythmically, allowing the heart to pump blood throughout the body by generating the force needed to propel blood through the circulatory system
What is the structure of the tricep?
composed of three distinct muscle heads - the long head, lateral head, and medial head
