What term describes a series a wavelike contractions of the smooth muscles in a single direction?
The wavelike contractions of the smooth muscle in the gastrointestinal system are called peristalsis. The purpose of peristalsis is to push boluses of food along the gastrointestinal tract. This is achieved by the waves of contractions in the smooth muscle followed by relaxation of the muscles, pushing the bolus (ball of food) a bit further along the digestive tract with each contraction. These contractions move food or chyme through the esophagus, and intestines. The same contractions also move urine down the ureter to the bladder.

What is the difference between skeltal muscles and cardiac muscles?
1 is connected also the cardiac muscles are the only of its kind to make the heart move and pump blood to where it needs to go. smooth muscles are conected to the bones.
What are examples of voluntary and involuntary muscle?
a voluntary muscle is a muscle that move when you tell it toMuscles in our hands (skeletal muscle) are called voluntary, because these muscles act according to the impulses (orders) given by our conscious brain.Heart (cardiac muscle) is an example of an involuntary muscle. It works all the time with impulses from our brain stem, which is involuntary.some more examples of voluntary muscles in our body are, muscles of the chest, neck, abdomen, etc. and those of involuntary muscles are, muscles of the digestive system, smooth muscles etc.
Do back people have more muscles than white people?
No, all human bodies have the same muscles.
What is spastic movement?
Spastic movement refers to involuntary muscle contractions that result in stiffness and tightness, often affecting coordination and control. This condition is commonly associated with neurological disorders such as cerebral palsy, where the signals from the brain to the muscles are disrupted. As a result, individuals may experience difficulty in performing smooth and controlled movements, leading to a jerky or rigid gait. Treatment options often include physical therapy and medications to manage symptoms.
What are the arms talks and treaties that ended the cold war?
arms= guns and guns are muscles so muscles like biceps
Involentary waves of muscles contractions that keep food from moving in one direction through the digestive system are called?
peristalsis
What causes wavelike contractions of muscles called peristalsis to begin when food moves through the digestive tract?
Peristalsis is initiated by the stretching of the digestive tract walls when food enters, which stimulates mechanoreceptors. This triggers the release of neurotransmitters that activate smooth muscle contractions in a coordinated manner. These contractions move in a wave-like pattern, propelling food along the digestive tract. Additionally, the autonomic nervous system plays a key role in regulating the intensity and frequency of these contractions.
What is the rhythmic wavelike motion produced by smooth muscles in tubular visceral organs?
Peristalsis
What is the term for Wavelike contraction of smooth muscles that move material through the digestive system?
peristalsis
What is a wavelike motion that pushes food downward?
Peristalsis is the wavelike motion of muscles that pushes food downward through the digestive tract. It helps propel food and liquids from the esophagus to the stomach and through the intestines for digestion and absorption.
What is dynamic contractions?
Dynamic contractions refer to muscle contractions that occur during movement, where muscles lengthen or shorten as they generate force. This type of contraction can be further classified into concentric contractions, where muscles shorten while producing force, and eccentric contractions, where muscles lengthen under tension. Dynamic contractions are essential for various physical activities, including walking, running, and lifting, as they enable the body to adapt to changing conditions.
What is clonus?
Involuntary contractions of the muscles, classically the long muscles associated with standing (the anti-gravity muscles).
How is food moved along the alimentary canal?
The involuntary motion that moves food through the alimentary canal is called peristalsis and is a wavelike contraction and relaxation of the intestinal wall smooth muscles. It pushes food along the intestine.
What is the major functions of cardiac muscles?
Heart Contractions
What are Repeated contractions of the cardiac muscles Called?
the heart
What is the neurotransmitter used to cause contractions in muscles?
Acetylcholine
Why does muscles have the most mitochondria in it?
Muscles are metabolically active. Contractions of muscles cost ATP. So there are many mitochondria
