What is a haustration?
Haustration is the mixing of feces to expose it to the surface of intestine to absorb water. they are sac like structures foldings in large intestine. At each of these constrictions, about 2.5 centimeters of the circular muscle contracts, sometimes constricting the lumen of the colon almost to occlusion. At the same time, the longitudinal muscle of the colon, which is aggregated into three longitudinal strips called the teniae coli, contracts. These combined contractions of the circular and longitudinal strips of muscle cause the unstimulated portion of the large intestine to bulge outward into baglike sacs called haustrations.
What are the differences between circular DNA and linear DNA in terms of their structure and functions?
Circular DNA is a closed loop structure, while linear DNA has two ends. Circular DNA is commonly found in bacteria and some viruses, while linear DNA is found in most eukaryotic organisms. In terms of function, circular DNA is more stable and efficient for replication, while linear DNA allows for more complex genetic information and gene regulation.
What are the closed loops of DNA?
Closed loops of DNA are circular strands of DNA found in bacteria, mitochondria, and chloroplasts. These loops are separate from the main linear DNA strands in the nucleus of eukaryotic cells. Closed loops of DNA contain essential genetic information for the functions of these organelles.
Circular DNA molecule that is not part of the chromosome in bacterial cells?
The circular DNA molecule that is not part of the bacterial chromosome is called a plasmid. Plasmids are small, extrachromosomal pieces of DNA that can replicate independently of the bacterial chromosome. They often carry genes that provide bacteria with additional functions, such as antibiotic resistance.
What are the two major groups of body muscles in annelids called?
Circular and Longitudinal muscles.
Functions of circular and longitudinal muscles in annelids?
In annelids, circular and longitudinal muscles work together to facilitate movement and locomotion. The circular muscles contract to elongate and narrow the body segment, while the longitudinal muscles contract to shorten and widen it. This coordinated action allows for both peristaltic movement, which helps the worm move through soil or water, and the ability to anchor parts of the body during burrowing or crawling. Together, these muscle layers enable efficient movement and adaptability in various environments.
Why do some muscles appear to run in different directions?
Some muscles appear to run in different directions because that is their inclinations. The direction may be circular or longitudinal.
Why inverse is called Circular function?
An inverse is NOT called a circular function. Only inverse functions that are circular functions are called circular functions for obvious reasons.
Where is myenteric plexus in the body?
between the circular and longitudinal muscle layers
What is circular function in math?
"Circular functions" is basically another name for "trigonometric functions".
What is the other name of functions?
circular functions
How are earthworms circular and longitudinal muscles used in locomotion?
When the circular muscles contract, they make the worm skinnier. When the longitudinal muslces contract, they make the worm shorter. This series of movements allows for the worm to move forward.
Detrusor muscle what are the 3 layers?

What are the three layers of smooth muscle that form the wall of the vas deferens?

Are longitudinal waves water waves?
Yes, water waves are a combination of both longitudinal and transverse motions.
In surface waves the combination of transverse and longitudinal motions produce what?
In surface waves, the combination of transverse and longitudinal motions produces circular motion. This circular motion results in the characteristic rolling or swirling movement of surface waves as they propagate through a medium such as water or the Earth's crust.
