The asthenosphere
The mantle (the inner portion of the mantle to be exact).
No, the lower portion of the crust and the upper portion of the mantle together are not called the core. The core is a separate layer found beneath the mantle, and it is divided into the outer core and inner core based on composition and properties.

The mantle extends to the core-mantle interface at approximately 2900 km depth. Thus, the mantle contains the lower portion of the lithosphere, the asthenosphere, and the mesosphere. The crust is made of the upper portion of the lithosphere.

It is secreted by a portion of the snail body called the mantle.
The largest portion of Earth by volume is the mantle, which makes up about 84% of the planet's total volume. The mantle is a layer of hot, solid rock that lies beneath the Earth's crust and extends down to the outer core.
The solid portion of the upper mantle which behaves as a brittle solid is known as the lithospheric mantle. This part of the upper mantle along with the crust forms tectonic plates.
