Proximal
Distal refers to 'further from the attachment point'. For example, the ankle is distal to the knee.
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.
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.
Origin is typically the proximal attachment of a muscle because it is the least moveable. The distal attachment is where a muscle inserts.
The relatively fixed point of a muscle's attachment to a bone is called the origin. It is typically located closer to the body's midline and usually remains stationary during muscle contraction.
Distal refers to 'further from the attachment point'. For example, the ankle is distal to the knee.
The less movable attachment point of a muscle is called the origin. This is typically the point of attachment that remains relatively fixed during muscle contraction, while the other end, known as the insertion, moves towards the origin.
Origin
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.
The origin is more proximal than the insertion for the attachment of muscles in the chicken wing. The origin is the fixed point of attachment, typically closer to the center of the body or the point of reference, while the insertion is the movable point of attachment, typically further away from the center of the body.
The term that means nearest the point of attachment or origin is "proximal." This term is commonly used in anatomy to describe the location of structures relative to the trunk of the body or the point of attachment of a limb. For example, the shoulder is proximal to the elbow.
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.

origin is where the muscle stars (generally the proximal attachment or in some cases medial) insertions is where the muscle ends (generally the distal or lateral attachment) for example the origin of the bicep would be the shoulder while the insertion is the elbow
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.
