What is the origin and insertion point for the deltoids?
The deltoid is very interesting muscle. It arise from the outer and lateral border of the clavicle and outer and lateral border of the spine of the scapula. From the corresponding inner border, you have insertion of the trapezius muscle. The deltoid muscle is inserted on the deltoid tuberosity on the lateral and middle part of the humerus bone. So it looks that the trapezius muscle continue as the deltoid muscle.
What is the origin and insertion of the shoulder muscles?
The shoulder muscles originate from the scapula (shoulder blade) and the clavicle (collarbone) and insert into the humerus (upper arm bone).
What is muscle attachment and function?
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.

What bone are attached to the sternocleidomastoid?
The sternocleidomastoid is a muscle that connects to your sternum, and the mastoid process.
Is the sternocleidomastoid named for its origin and insertion?
Yes, the sternocleidomastoid muscle is named for its origins on the sternum (sterno-) and clavicle (cleido-) and its insertion on the mastoid process of the temporal bone.
What is reverse origin and insersion?
Reverse origin and insertion refers to the changing of the attachment points of a muscle. When the origin and insertion of a muscle are reversed, the muscle's previous insertion point now becomes the origin, and vice versa. This can have an impact on the muscle's function and movement.
What is the difference between the origin and the insertion of the muscle?
The origin of a muscle is where the muscle starts ("the starting point"). The insertion of a muscle is where the muscle ends ("the ending point"). Also, the insertion of the muscle is what moves a lot (contrary of the origin where the muscle mostly stays stationary).
What is the opposite origin of a muscle?
Insertion
Is groove of the humerus is origin of biceps muscle?
yes
What is the movable point to which a muscle may be attached?
The "movable" end of a muscle is called the insertion. The "immobile" end is called the origin. Shortening, or contraction, of a muscle causes the origin and insertion to become closer to one another.
What is the attachment for the flexor muscles of the forearm?
The origin attachments are on, or near, the medial epicondyle of the humerus.
