What are the muscles that are slow in contraction and relaxation?
smooth muscle
When contraction of the smooth muscle in a blood vessel wall results in the vessel is referred to as being in a condition of?
vasoconstriction
What does vasodilation in the skin and viscera result from?
relaxation of smooth muscle in the arterioles
The alternating contraction and relaxation of opposing layers of smooth muscle is referred to as?
Peristalsis
What special feature of smooth muscle allows it to stretch without immediately resulting in a strong contraction?
stress-relaxation responsestress-relaxation response
What is relaxation of the smooth muscle in the artery wall which causes the artery wall to become larger?
Vasodilation
Why artery called resistance vessels?
The contraction and relaxation of the smooth muscle in their walls can change their diameter, thus changing the level of pressure (large diameter yields low pressure and smaller diameter yields high pressure).
What is the MOA of hydralazine?
The mechanism of action of hydralazine is not well known. It interferes with the action of the second messenger IP3, limiting calcium release from the sarcoplasmic reticulum of smooth muscle. This results in an arterial and arteriolar relaxation answer found on Wikipedia
What is in the sarcoplasmic reticulum in muscle?
The sarcoplasmic reticulum is a special type of smooth endoplasmic reticulum. It releases calcium ions during muscle contraction and absorbs them during relaxation.
The diameter of bronchioles can change because their walls contain?
Smooth Muscle tissue relaxation and contraction is responsible for dilation and constrictions of the bronchioles, respectively.
What small structures located within the bronchial tree are composed primarily of smooth muscle?
Bronchioles are smaller tube divisions of bronchi. Walls of bronchioles contain smooth muscle and no cartilage. This helps in contraction and relaxation which allows the flow of air to alveoli.
What is the muscle that is found in the small intestine?
