these are the surfaces on a tooth, which are in contact with the adjacent teeth. there are 2 proximal surfaces, namely mesial and distal. the former is towards the midline and the latter is away from the midline.
A junction of two tooth surfaces is called an embrasure. Embrasures are the V-shaped spaces formed between adjacent teeth. They play a role in maintaining proper gingival health and also help in self-cleansing of the teeth during activities like chewing.

The proximal surface is the acromion of the scapula while the distal part is the head of the humerus.

Newton's rings is a phenomenon when an interference pattern is created by the reflection of light between two surfaces. The surfaces are a spherical surface and an adjacent flat surface.
A human bladder neck is a constricted portion of the urinary bladder, which is formed by the meeting of its inferolateral surfaces proximal to the opening of the urethra.
it is called a 'dike'
Surfaces that touch food are typically referred to as food contact surfaces. It is important for these surfaces to be clean and sanitized to prevent contamination and ensure food safety.
Class IVFound on the proximal surfaces of incisors and canines, but also will involve the incisal edge.

The expanded ends of bones that form joints with adjacent bones are called articular surfaces. These surfaces are covered with a layer of smooth cartilage to reduce friction and allow for smooth movement within the joint.
