Smooth muscle (involuntary)lines ducts and vessels.
Smooth muscle lines hollow structures like ducts and vessels that contract involuntarily. In contrast, skeletal muscle is under voluntary control.
peristalsis
Peristalsis is the name for this phenomenon.
Smooth muscles are found in hollow parts of the body. For example they are found in the stomach, intestines, blood vessels, and the bladder. They can contract in all directions.
A capillary is hollow. It is the smallest of the blood vessels, the tubes that carry blood.
smooth muscle
Muscles contract. The other organs that contract rely on the action of voluntary or involuntary muscle tissue. These include hollow, peristaltic organs like the intestine or ureter, as well as blood vessels. The uterus is also a muscle that contracts during labor.
vessel elements, tracheids, fibres, and parenchyma
It better not be. It is filled up with brain tissues and blood vessels.
Cytoskeleton is completely made up of proteins.Micro tubules are hollow protein structures.
The description of microtubules is hollow rods or hollow cylindrical structures. They mainly help to shape and support the cell.
The three types of muscle are the 1) Cardiac muscle (which is only located in the heart.. your heart's made of this muscle) 2) Skeletal muscle (muscle that is around your bones) 3) Smooth muscle (Located in hollow internal structures such as blood vessels, stomach, etc)
Shell structures have solid surfaces. They are hollow and there shape is often curved.Eg: Eggs, helmets, conch shell etc.Some of the examples of shell structures are storage tanks (water, oil, gas), domed roofs, and pressure vessels.
