It's called the lower mantle.
The endocardium is the innermost layer of the heart wall.

This is in the mantle or upper mantle.
Very good question. Many people have been wondering this, actually. How thick is the Earth's mantle? Well, I did some research and found out that the Earth's mantle is about 1800 miles thick, or 2900 kilometers thick. It contains about 80 percent of the Earth's mass. Wow!

The innermost layer of the hair is the Medulla.

The core is called the core because it is the central part or innermost part of something. In the context of the Earth, the core is the central part of the planet, located beneath the mantle and consisting mainly of iron and nickel.
The part of the mantle below the lithosphere is called the Asthenosphere.
The lower part of the mantle is called the "lower mantle" or "mesosphere", while the upper part of the mantle is referred to as the "upper mantle" or "asthenosphere".
The innermost part of an object is called its core.
The layers of the Earth are crust- outer, mantle- middle, core- innermost.
The physical layers of the Earth, from the outermost to the innermost, are the lithosphere (including the crust and uppermost mantle), asthenosphere (part of the upper mantle), mesosphere (lower mantle), outer core (liquid layer), and inner core (solid innermost layer). Each layer has distinct physical properties and compositions that contribute to Earth's overall structure and behavior.
The mantle is a part of a terrestrial planet or other rocky body large enough to ... encloses the iron-rich hot core.The inner core of the Earth , its innermost part as detected by seismological ... rigidly connected to Earth's solid mantle.
The lower mantle is a solid layer located between the upper mantle and the outer core of the Earth, composed mainly of silicate minerals. In contrast, the inner core is a solid sphere composed primarily of iron and nickel at Earth's center due to extreme pressure. The lower mantle is part of the mantle layer, whereas the inner core is part of the core layer of the Earth.
The Earth's mantle, core, and crust are all part of the geosphere, which encompasses the solid Earth. The geosphere includes the crust (outer layer), mantle (middle layer), and core (innermost layer) of the Earth.
