What else can I help you with?
What of the muscle tissue can sustain longer contraction?
smooth muscle
What is the medical term meaning contraction of the smooth muscle in the walls of the bronchi and bronchioles that tighten and squeeze the airway shut?
Bronchoconstriction or bronchospasm is the medical term that refers to the contraction of the smooth muscle in the walls of the bronchi and bronchioles that tighten and squeeze the airway shut.
A maximal sustained muscle contraction is called a?
tetanic contraction.
What conditions cause contractions of arteriole smooth muscle?
Asthma causes contraction of the bronchial smooth muscle.
What are the muscles that are slow in contraction and relaxation?
smooth muscle
What does noradrenaline do?
It can cause vascular smooth muscle contraction
What is the type of contraction that Peristalsis is seen in?
smooth muscle
Why is the endothelium smooth?
Because it is an involuntaru muscle contraction
Which muscle contraction does acetylcholine and norepinephrine affect?
Acetylcholine and norepinephrine both affect smooth muscle contraction. They stimulate contraction in some muscles and inhibits contraction in others.
The two neurotransmitters that affect smooth muscle cells are acetylcholine and?
norepinephrine. Acetylcholine mainly causes smooth muscle contraction, while norepinephrine can either cause contraction or relaxation depending on the type of receptor it binds to on the smooth muscle cell.
What is smooth sustained contraction due to rapid stimuli?
Smooth sustained contraction due to rapid stimuli refers to a sustained muscle contraction that occurs in response to a series of quick, successive stimuli without a complete relaxation phase between them. This phenomenon, often seen in smooth muscle tissue, results in a prolonged state of contraction, allowing for functions such as vasoconstriction or peristalsis in the digestive tract. The rapid stimuli lead to an accumulation of calcium ions within the muscle cells, enhancing the contractile response. This type of contraction is essential for maintaining continuous muscle tone and function in various physiological processes.
Dense bodies are characteristic of?
Dense bodies are characteristic of smooth muscle cells. These structures help anchor actin filaments in the cell and facilitate muscle contraction by linking adjacent cells. Dense bodies play a crucial role in the mechanical coordination of smooth muscle contraction.
