Muscle Proteins
This protein is made of two strands of spheres and is considered the thin filament
What is actin
the top-most chamber of the heart, divided into a right an left side
What is the atria
These vessels carry blood away from the heart
what are arteries
This structure transferrs a message from the nerve to the sarcoplasmic reticulum
What is the t-tubule
This condition is also known as hardening of the arteries
What is atherosclerosis
Each unit of this protein contains a tail, a hinge, and a bifurcated head
What is myosin
the bottom-most part of the heart divided into a right and left side
what is the ventricle
These vessels carry blood back to the heart
What are veins
This structure releases calcium to start the process of a twitch
What is the sarcoplasmic reticulum
What a monocyte turns into after it has eaten an LDL and squeezed through the wall of the blood vessel
what is a foam cell
This protein covers the active sites on Actin
What is tropomyosin
This valve connects the atria to the ventricle.
What is an AV valve
These vessels take blood from the right side of the heart to the lungs
What are the pulmonary arteries
After calcium is released from the SR it will bind to troponin causing this structure to change its shape and uncover the active sites on actin
what is tropomyosin
The rupturing of a blood vessel in the brain results in this condition.
What is a stroke
This protein is elastic in nature and gives myosin an attachment to the z-line
What is titan
This valve is made of 3 cups that allow the ventricle to empty
What is the Semi-lunar valve
These vessels carry blood from the lungs to the left side of the heart
What are the pulmonary veins
When the active sites on actin are uncovered the myosin head will attach and then do this:
What is bent towards the tail.
A blockage in one of the coronary arteries causes this condition
What is a myocardial infarction (heart attack)
This protein has 3 binding sites and at rest allows tropomyosin to cover actin's active sites
What is troponin
This structure separates the left and right side of the heart
These are the smallest vessels in the body that allow for the exchange of substances between the blood and the tissues
What are capillaries
This event requires ATP
What is the recocking of the myosin head
This disorder causes the valves of the heart to become stiff and brittle
What is valve stenosis
