Corticobulbar tracts carry information that coordinates the voluntary movement of all of the following except:

Name, locate, and briefly describe the functions of three descending tracts that are referred to as the direct pathways.

Outline the three classification systems for receptors. List the types of receptors according to each classification and give examples.

Third-order neurons:

Gamma motor neurons are responsible for the innervation of _____ fibers of the muscle spindle.

Modality of receptors refers to the fact that a receptor will only respond if a stimulus is of sufficient strength.

Receptors for pressure and vibration that consist of an oval multi-layered capsule surrounding a dendrite, and that are located in the skin as well as subcutaneous and submucosal tissues, are called _____.
