The lower part of the mantle is actually names the mesosphere. It is overlain by the asthenosphere which is part of the upper mantle and this in turn is overlain by the lithosphere which is made up of the very uppermost mantle and the crust.
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.
The lithosphere is defined as the crust plus the brittle, uppermost mantle to which it is attached. The part of the upper mantle called the asthenosphere is ductile, and is the portion of the mantle on which the lithosphere 'floats'. Essentially, it is a difference in the degree of ductility. The lithosphere is brittle; the mantle is ductile.
The mantle is composed of the upper mantle and the lower mantle. The upper mantle is known for its plasticity and convective movement, while the lower mantle is more rigid and is characterized by high-pressure conditions.
the upper mantle(lithosphere)and the lower mantle(mesosphere)
The asthenosphere lies in, and is the upper ductile part of, the mantle. It is the layer directly underneath the lithosphere; the layer composed of the crust and uppermost rigid mantle.
The lithosphere, asthenosphere, and mesosphere are all located within the Earth's upper mantle, which is part of the mantle layer. The lithosphere is the rigid outermost layer of the Earth, including the crust and uppermost mantle. The asthenosphere is a partially molten layer below the lithosphere, while the mesosphere is a solid layer beneath the asthenosphere.
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.
The mantle is divided into two main layers: the upper mantle and the lower mantle. The upper mantle is further divided into the lithosphere and the asthenosphere. The lithosphere is rigid and made up of the crust and the upper part of the mantle, while the asthenosphere is semi-molten and capable of flowing.

the upper mantle(lithosphere)and the lower mantle(mesosphere)
After the lithosphere is the asthenosphere, then comes the lower mantle. After that is the outer core, and then is the inner core.
The three sub layers of the mantle are the lithosphere, asthenosphere, and mesosphere. The lithosphere is the rigid outer layer consisting of the crust and upper part of the mantle. The asthenosphere is a partially molten layer beneath the lithosphere that allows for the movement of tectonic plates. The mesosphere is the lowermost and solid part of the mantle.
The asthenosphere lies in, and is the upper ductile part of, the mantle. It is the layer directly underneath the lithosphere; the layer composed of the crust and uppermost rigid mantle.
The difference between the lithosphere and the asthenosphere is that the asthenosphere is the lower part of the upper mantle it behaves like a plastic but flows much more easily than the rest of the mantle. The lithosphere however, includes the entire crust and the uppermost part of the mantle, it is more rigid and brittle and doesn't flow.
The mesosphere is the sphere that contains the lower mantle. It is located above the outer core and under the lithosphere and asthenosphere.
The lower boundary of the asthenosphere is not well defined. It lies below the lithosphere and above the lower mantle and outer core. It usually lies at depths of 80-200 km but can range as deep as 700 km.
