Verified step by step guidance

Understand the concept of directional terms in anatomy: Directional terms are used to describe the location of structures in relation to other structures or locations in the body. Examples include terms like 'superior,' 'inferior,' 'proximal,' 'distal,' 'medial,' and 'lateral.'

Review the definition of a suture: A suture is a type of joint found only in the skull. It is a fibrous joint that connects adjacent bones tightly together, allowing little to no movement.

Analyze the options provided: The correct directional term should describe the location of a suture in relation to the bones it connects. Consider each option carefully: 'Between adjacent bones,' 'Deep within the bone marrow cavity,' 'At the distal end of a long bone,' and 'On the surface of a single bone.'

Eliminate incorrect options: A suture is not located deep within the bone marrow cavity (this refers to internal structures like marrow), nor is it at the distal end of a long bone (this refers to the ends of bones like the femur or humerus). It is also not on the surface of a single bone, as sutures connect two or more bones.

Conclude that the correct directional term is 'Between adjacent bones,' as sutures are found at the junctions where two bones meet, such as the parietal and frontal bones in the skull.
