What part of the motor pathway inhibits inappropriate movements?

Primary motor cortex motor pathway inhibits inappropriate movements.

Explanation:

It is a part of brain that controls the planning and execution of voluntary movements. It is present in the frontal lobe. It works by generating nerve impulses that controls various movement. If at any case a part of motor cortex gets damaged, it may affect the movement of body parts.

This happens if in case a person suffers from stroke. Which results in progressive regeneration and muscle damage to some patients, results in failure in the movement in any way.  

where in your body is there an enzyme that does function at a high or low ph? what is the name of that enzyme and its function?

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
