Proximal
In medical terms, the closest point of attachment is referred to as the proximal end. This typically refers to the end of a bone or muscle that is closer to the center of the body or the point of origin.
closer to the origin of the body part or the point of attachment of a limb to a body trunk. For example, The elbow is proximal to the wrist
Distal is away from the center of body trunk or point of attachment. The wrist is farther away from center of body trunk. Proximal is closest to the body central axis or point of attachment, so the shoulder is proximal.
Farther from the origin of a body part or the point of attachment of a limb to the body trunk. e.g., your fingers are distal to your elbow

Proximal means nearest the point of attachment or origin.

Situated nearer to the center of the body or the point of attachment.
The two attachment points are the origin and insertion. The origin is the immovable (or slightly moveable point. The insertion is the movable point. The insertion always moves towards the origin.
Origin and Insertion One of the points of attachment is the ORIGIN (typically the non-moving point of attachment). The other point of attachment is the INSERTION (typically the moving point of attachment). For example - when the brachialis muscle (located on the upper arm) contracts - it shortens the distance between the origin (on the humerus - the upper arm bone and the insertion (on the radius - the forearm bone). The humerus does not move, but the radius does move - it moves closer to the humerus.

Where a muscle attaches to a bone is at the origin and insertion points. The origin is the immovable (or slightly moveable) attachment point and the the insertion is the movable attachment point. During contraction the insertion moves towards the origin. HOW a muscle attaches to a bone is through tendons.
The origin is the "immovable" point of attachment of a muscle to a bone.
According to Anthony's Textbook of Anatomy and Physiology the origin is that point of attachment that does not move when the muscle contracts, and the point of attachment that does move when the muscle contracts is the insertion. Muscles and muscle groups that that directly perform specific movements are prime movers or agonists.
