EXTRINSIC MUSCLE Meaning and
Definition
-
An extrinsic muscle refers to a type of muscle that is located outside of a specific organ or structure, typically connecting it to another body part or system. These muscles function to control movements and provide stability and support within the body. Unlike intrinsic muscles, which are found within an organ or structure, extrinsic muscles have attachments outside of the area they are associated with.
Extrinsic muscles are responsible for producing gross movements and are often larger and more powerful compared to intrinsic muscles. They play a crucial role in maintaining proper body posture, coordinating complex movements, and generating force across joints. Due to their external location, extrinsic muscles are able to control and manipulate various body parts, such as limbs and digits, enabling humans and other animals to perform a wide range of movements.
These muscles are commonly found in the limbs, where they attach to bones and provide the necessary propulsion for running, jumping, and lifting. They can also be found in areas like the eye, where they control the movement of the eyeball, and in the tongue, where they facilitate speech and swallowing. In addition to their mechanical function, extrinsic muscles are often innervated by motor neurons from the central nervous system, allowing for voluntary control over their actions.
In summary, extrinsic muscles are anatomical structures present outside of a specific organ, which are responsible for generating gross movements, facilitating proper posture, and controlling various body parts.

Etymology of EXTRINSIC MUSCLE
The word "extrinsic" in the term "extrinsic muscle" has its roots in Latin. It is derived from the Latin word "extrinsecus", which means "from the outside".
The term "extrinsic muscle" is used in anatomy to refer to muscles that originate outside of the body part they act upon. These muscles usually have their origin on bones, fascia, or ligaments and insert onto some other structure to produce movement. Examples of extrinsic muscles include those that move the limbs or control the movements of the eyes.
