Skeletal, Smooth and Cardiac Muscle Flashcards
What does a decrease in ATP cause?
skeletal, smooth, and cardiac muscles to not function
How do skeletal muscles produce movement of the limbs?
the brain sends signals to the spinal cord and from there to skeletal muscles (striated)
What happens after the skeletal muscles contract when trying to produce movement?
the movement is caused by the molecular interaction of actin and myosin and ATP for both contraction and relaxation
Unlike skeletal and cardiac muscles, Smooth muscle is ___
not under voluntary control
Where is smooth muscle found
in the intestinal tract and blood vessels
How does smooth muscle control blood vessels?
by altering their diameter
What are the blood vessels under the control of?
the autonomic nervous system
Where is cardiac muscle located?
the heart walls, specifically in the myocardium
Where does cardiac tissue receive its oxygen from?
coronary arteries
What are coronary arteries used for?
to produce ATP by way of oxidative phosphorylation
Myoglobin
protein found in the cardiac cells
What muscles does the autonomic nervous system control?
smooth and cardiac muscles
What muscles does the somatic nervous system control?
skeletal muscle
