What is the progressive wavelike movement that occurs involuntarily in hollow tubes of the body?
Peristalsis is the progressive wavelike movement that occurs involuntarily in hollow tubes of the body, such as the digestive system. It helps propel contents through these tubes, like food through the esophagus or waste through the intestines.
What is a progressive wavelike movement htat occurs inuoluntarily in hollow tubes or the body?
Peristalsis It is the involuntary wavelike movement that occurs in almost all the tubular structures in the body. It is especially seen in GIT (Gastrointestinal tract) Fallopian tubes, etc. In GIT this movement is responsible for the propulsion of the food further into the tract and its proper digestion. In fallopian tubes this movement helps to carry the ovum towards uterus. This movement is controlled by autonomic nervous system.
What type of muscle tissue lines hollow structures like ducts and blood vessels that contract involuntarily?
Smooth muscle (involuntary)lines ducts and vessels.
What is a tiny hollow tube made of proteins that is involved in the movement of organelles?
The answer is Microtubule.
What type of muscle can hold prolonged but slow contractions?
Smooth muscle is the type of muscle that can hold prolonged but slow contractions. It is found in the walls of hollow organs, such as the intestines and blood vessels, and operates involuntarily. Smooth muscle contractions are sustained for longer periods compared to skeletal muscle, allowing for functions like the continuous movement of food through the digestive tract.
Is the guil of the contour feather solid or hollow?
The quill of a contour feather is hollow. This hollow structure helps keep the feather lightweight while providing strength and flexibility, which is essential for the feather's role in insulation and aerodynamics in birds. The hollow quill also allows for efficient movement and minimizes the energy required for flight.
Are ostrich's bones hollow?
Generally yes, except perhaps for the leg bones which are thicker and stronger.
Examples of hollow bodied animals?
Coral, jellyfish, and aneomes are hollow bodied animals
Are hollow tubes of protein that maintain cell shape and permit movement of cell organelles. A) Muscles B) Ribosomes C) Microtubules D) Nuclear pores?
C) Microtubules are hollow tubes of protein that maintain cell shape and facilitate the movement of cell organelles. They are part of the cytoskeleton and play a crucial role in cellular structure, transport, and division.
Why are leg bones hollow?
Leg bones in some animals, like birds, are hollow to reduce weight without sacrificing strength. This adaptation allows for easier flight or agile movement. The hollow structure also allows for the storage of calcium and other minerals needed for bone strength.
What thin hollow cylinders that assist chromosome movement during cell division?
Spindle fibers are thin hollow cylinders that assist in chromosome movement during cell division. These structures are made of microtubules and help separate the chromosomes, ensuring that each daughter cell receives the correct number of chromosomes.
Consist of hollow tubes which provide support for the cell?
The cytoskeleton is a network of hollow tubes made of proteins called microtubules that provide support and maintain the shape of the cell. They are involved in various cellular functions such as cell division, intracellular transport, and movement.
