Detailed explanation-1: -Proximal means nearer to the center (trunk of the body) or to the point of attachment to the body. If another reference point is given, such as the heart, the proximal point of another organ or extremity is the point closest to the heart, central rather than peripheral. Proximal is the opposite of distal.

Detailed explanation-2: -In medicine, refers to a part of the body that is closer to the center of the body than another part. For example, the knee is proximal to the toes. The opposite is distal.

Detailed explanation-3: -Superficial describes a position closer to the surface of the body. The skin is superficial to the bones. Deep describes a position farther from the surface of the body. The brain is deep to the skull.

Detailed explanation-4: -Dorsal: toward the back; equivalent to posterior (ex: the spine is dorsal to the breast). Proximal: nearer to point of reference or attachment (ex: the shoulder is proximal to the elbow or the elbow is proximal to the wrist).

Detailed explanation-5: -In medicine, it refers to parts of the body further away from the center. For example, the hand is distal to the shoulder. The thumb is distal to the wrist. Distal is the opposite of proximal. Distal refers to distance, while proximal indicates proximity.
