The internal surfaces such as inside blood vessels and lymph nodes are covered by endothelium and the external surfaces are covered by epithelium. "Epithelial tissues line the cavities and surfaces of structures throughout the body, and also form many glands." (Wikipedia)
The human body typically has 206 bones. This number can vary slightly from person to person due to the presence of additional small bones or fusion of certain bones.
An adult human body typically has 206 bones. This number can vary slightly from person to person due to the presence of small accessory bones or fusion of certain bones.
The common house fly has millions of cells in its entire body. It is amazing how such a small creature has so many cells.
The human body has one hypothalamus. It is a small region of the brain located below the thalamus and plays a crucial role in controlling various physiological functions such as temperature regulation, hunger, and sleep.

He was covered in many eyes. i believe it was a total of 100 eyes all over his body.
There are many small glands in the body. Perhaps you are thinking of pituitary?
There are no rules, use whatever you find easiest. Most people use synthetic sponges for cleaning tasks. Washing the body may be done with either a synthetic or a natural sponge. A sponge with a scourer attached is useful for many jobs including dish washing.
The body of a sponge is a collection of a few different types of cells loosely arranged in a gelatinous matrix called a 'mesohyl', mesoglea or mesenchyme. This mesohyl is the connective tissue of a sponge body and it is supported by the skeletal elements. The skeletal elements of sponges are variable and important in taxonomy. Throughout this body run canals through which water flows, there is considerable variation in the complexity of these canals. The canals have openings to the outside which are called pores, where the water enters the sponge system these pores are usually small and are called 'ostia' and where the water leaves the sponge system the pores are larger, often singular and are called 'oscula' (singular osculum). Many if not most of these canals are lined with special flagellated cells called 'choanocytes'. These choanocytes keep the water flowing through the canals in the correct direction by beating their flagellum, they are also important in trapping food items.
a sponge has zero eyes thats all I know!

I personally, dont use a sponge beacuse it gets dirty too much, i just mist the crabitat until it have enough humidity. You dont have to change the sponge, if it gets really dirty, boil it in distilled water and place it back in. You need to change the hermie sponge when it becomes so small you cant really use it.
Yes, a sponge is permeable. It has a porous structure that allows liquids and gases to pass through its many small holes. This property enables sponges to absorb water and other substances, making them effective for cleaning and soaking up spills. However, the degree of permeability can vary depending on the material and density of the sponge.
