The cell bodies of motor neurons to skeletal muscles are located in the A. Posterior/dorsal gray horns B. Limbic system C. Anterior/ventral gray horns D. Gray commissure

The cell bodies of motor neurons to skeletal muscles are located in the anterior/ventral gray horns.

Neurons are cells characterized by a body (called soma), and different kinds of prolongations that will have the task to carry the information to other neurons or tissues - these prolongations are axons (which are usually very long) and dendrites (much shorter than axons).

The motor neurons are the ones that conduct the electric impulse from the motor cortex in the brain to the skeletal muscles in our bodies, making muscle contraction and movement possible.

There are two types of motor neurons:

Thus, we can conclude that the somas of lower motor neurons that transmit its impulse to skeletal muscle are located in the anterior gray horns of the spinal cord.

velocity and height

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
