UNIBASAL MUSCLE Meaning and
Definition
-
A unibasal muscle refers to a type of muscle that originates or attaches at a single, basal site or base. It is characterized by having only one attachment point or origin in the body, usually at the base or bottom of a specific structure. This muscle type is typically seen in organisms where movement or function is limited to a single plane or direction.
In human anatomy, a notable example of a unibasal muscle is the rectus abdominis muscle. This muscle is located in the front of the abdomen and is responsible for flexing the trunk or bending the torso forward. It originates from the pubic bone, specifically the pubic crest, and runs vertically along the midline of the abdomen, attaching to the sternum and the fifth, sixth, and seventh ribs. The rectus abdominis muscle plays a crucial role in core stability, postural support, and also aids in the breathing process.
Unibasal muscles are often aligned with a specific direction of force or movement, which allows for efficient and controlled motion in a particular plane. They tend to have a linear arrangement of muscle fibers, which further contributes to their unidirectional action. This muscle type is distinct in its attachment and placement within the body, providing stability and control during specific movements.

A muscle with a lateral tendon to which the fibers run obliquely, giving a resemblance to one lateral half of a feather.

Etymology of UNIBASAL MUSCLE
The term "unibasal muscle" is a combination of two words: "unibasal" and "muscle".
1. Unibasal: It consists of the prefix "uni-" meaning "one" or "single", and the word "basal" which refers to the base or bottom part of something. In anatomy, "basal" generally refers to structures located at the base or bottom of an organ or body part.
2. Muscle: It is derived from the Latin word "musculus", which means "little mouse". This term was used due to the resemblance of some muscles to the shape of mice. Over time, it started to be used to describe the contractile tissues responsible for body movement.
Combining these two terms, the etymology of "unibasal muscle" can be understood as a muscle with a single point of attachment or origin located at the base of a structure.
