funny bone
The attachment of the muscle that is on the moving bone is known as the insertion. In contrast, the origin is the attachment of the muscle on the non-moving bone.
Origin is typically the proximal attachment of a muscle because it is the least moveable. The distal attachment is where a muscle inserts.
a direct attachment
Ptosis may occur because the levator muscle's attachment to the lid is weakening with age.
A bony skeleton refers to the framework of bones that provides support and structure to the body of vertebrates, including fish, amphibians, reptiles, birds, and mammals. It helps protect the internal organs, allows movement, and provides attachment sites for muscles. The bony skeleton is composed of individual bones that are connected by joints.
Shoulder joint is a very special type of joint. In this scapula bone is not attached to thorax by any bony attachment, except through clavicle bone. Here The medial border of scapula is pushed inside the sheet of muscle. You call them rhomboid-us major and minor on one hand and serratus anterior on other hand. The trapezius and deltoid muscles are interrupted by acromial process of scapula. So that way shoulder has only single bony attachment with the trunk.
A tendon connects bone to muscle and a ligament connects bone to bone. The actual point of attachment where a muscle connects to a bone is called the process(n) of the bone. This is a bulge in the bone where muscle can attach to provide movement. Not all muscles will attach to bone via a bony process as described above, it may can sometimes by a fleshy attachment (e.g. sternocleidomastoid to clavicle). So broader terms are simple origin and insertion, origin being the attachment that tends to be fixed and insertion being the attachment that tends to move when the muscle is contracted.
Origin is typically the proximal attachment of a muscle because it is the least moveable. The distal attachment is where a muscle inserts.
The deltoid tuberosity is proximal to the lateral condyle of the humerus. It's the site of attachment for the deltoid muscle.

What is the Orgin of a muscle, and the moveable part is the insertion
Bony prominence is developed by muscle pull. That is why you have well marked bony markings in case of a male bones. But then it requires the comment from the expert as to why there are depressions on some muscle origins or insertions.
Many bones have ridges and protuberances which provide an area for muscle attachment.
origin
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.
