Both statements are true.
The inner side of the wall of a hollow structure is referred to as internal. In contrast, the outer side of the wall of a hollow structure is external.
Both statements are true.
The ventral part is directed toward the anterior and is considered the opposite of the dorsal part when considering the entire body.
Both statements are true.
The dental professional MUST have a thorough understanding of head and neck anatomy when performing patient examination procedures, both extraoral and intraoral. Certain terms can be used to give information about the depth of a structure in relationship to the surface of the body.
