Where muscle begins and is located nearest the mid-line of the body or on a less movable part of the skeleton?

The muscle that begins nearest the mid-line of the body and is located on a less movable part of the skeleton is referred to as the "origin" of the muscle. The origin typically attaches to a stable bone or structure, allowing the muscle to exert force effectively during movement. In contrast, the "insertion" of the muscle is usually found on the more movable part of the skeleton, allowing for greater mobility and movement.


Which muscle attachment is usually fixed or immovable?

What is the Orgin of a muscle, and the moveable part is the insertion


What muscle is the lesser moving part?

There are two points of attachment for a (skeletal) muscle, the origin and the insertion. The origin is the immovable (or slightly movable) part. The insertion moves towards the origin.


The origin is the distal attachment of a muscle?

Origin is typically the proximal attachment of a muscle because it is the least moveable. The distal attachment is where a muscle inserts.


What is The movable end of the muscle?

insertion


What is the immovable part of muscle bundles?

The immovable part of muscle bundles is called the origin. This point is where the muscle attaches to a stationary bone or structure, providing a stable anchor during muscle contraction. In contrast, the other end of the muscle, known as the insertion, attaches to a movable bone, allowing for movement when the muscle contracts.


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.


Define Origin and insertion?

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


What is the end of the muscle that is attached to the movable bone and moves when a skeletal muscle contracts?

Insertion point, which most probably is a tendon.


The end of the muscle that is attached by means of a tendon to the movable bone and is opposite to the origin?

Insertion


The end of the muscle that is attached by means of a tendon to the movable bone and opposite to the origin?
