Physiology
(noun)
The relatively immovable point of attachment for a muscle.
Calculus
(noun)
the point at which the axes of a coordinate system intersect
Physics
(noun)
The center of a coordinate axis, defined as being the coordinate 0 in all axes.
Examples of origin in the following topics:
-
Muscles of the Wrist and Hand
- Attachments - Originates from the ulna and attaches to the radius.
- Attachments - Originates from the humerus and attaches to the ulna.
- Extensor Digiti Minimi – Originates from the extensor digitorum.
- Attachments - Originates from the wrist and attaches to the thumb.
- Attachments - Originates from the wrist and attaches to the thumb.

The Cross Product
- The cross product of two vectors is a vector which is perpendicular to both of the original vectors.
- The result is a vector which is perpendicular to both of the original vectors.
- Because it is perpendicular to both original vectors, the resulting vector is normal to the plane of the original vectors.
- If the two original vectors are parallel to each other, the cross product will be zero.
- The magnitude of vector $c$ is equal to the area of the parallelogram made by the two original vectors.
-
Posterior Muscles
- Attachments - Originates from the spine and attaches to ribs 9 through 12.
- Attachments – Originates from the upper spine and attaches to the skull.
- All three originate from a common tendon associated with the pelvis.
- Attachments - A broad origin on the upper regions of the spine, with each origin attaching several vertebrae higher or to the skull.
- Attachments – A broad origin up the length of the spine, with each origin attaching several vertebrae higher.
-
Neck Muscles
- It originates from the mandible and attaches to the hyoid bone.
- Attachments – Originates from the upper spine and attaches to the skull.
- Attachments - Originates from the spine and attaches several vertebrae higher.
- Attachments - A broad origin on the upper regions of the spine, with each origin attaching several vertebrae higher or to the skull.
- Attachments – A broad origin up the length of the spine, with each origin attaching several vertebrae higher.

Evolution of Viruses
- Although biologists have accumulated a significant amount of knowledge about how present-day viruses evolve, much less is known about how viruses originated in the first place.
- While most findings agree that viruses don't have a single common ancestor, scholars have yet to find one hypothesis about virus origins that is fully accepted in the field .
- One possible hypothesis, called devolution or the regressive hypothesis, proposes to explain the origin of viruses by suggesting that viruses evolved from free-living cells.
- As technology advances, scientists may develop and refine further hypotheses to explain the origin of viruses.
- These researchers hope to one day better understand the origin of viruses, a discovery that could lead to advances in the treatments for the ailments they produce.
-
The Origins of Language
- The origin of language is a widely discussed and controversial topic due to very limited empirical evidence.
- The origin of language in the human species is a widely discussed topic.
- There is no consensus on ultimate origin or age.
- Theories about the origin of language can be divided according to their basic assumptions.
- The origin of language in the human species is a widely discussed topic.
-
Muscles that Cause Movement at the Foot
- Attachments - Originates from the heel and attaches to the toes.
- Attachments - Originates from the fibula and attaches to the big toe.
- Attachments - Originates from the heel and attaches to the big toe.
- Attachments - Originates from the heel and attaches to the little toe.
- Attachments - Originates from the tendons of flexor digitorum longus.
-
Components of a Vector
- To visualize the process of decomposing a vector into its components, begin by drawing the vector from the origin of a set of coordinates.
- Next, draw a straight line from the origin along the x-axis until the line is even with the tip of the original vector.
- To find the vertical component, draw a line straight up from the end of the horizontal vector until you reach the tip of the original vector.
- You should find you have a right triangle such that the original vector is the hypotenuse.
- The original vector, defined relative to a set of axes.

Racial and Ethnic Diversity in the U.S.
- White are considered those having origins in any of the original peoples of Europe, the Middle East, or North Africa ; Black or African American are considered those having origins in any of the Black racial groups of Africa ; Native American are considered those having origins in any of the original peoples of North, Central and South America, and who maintain tribal affiliation or community attachment; Asian are considered those having origins in any of the original peoples of the Far East, Southeast Asia, and the Indian subcontinent ; Pacific Islanders are those having origins in any of the original peoples of Hawaii, Guam, Samoa, or other Pacific Islands; see also Pacific Islander American.
- The question on Hispanic or Latino origin is separate from the question on race.
- "Hispanic or Latino origin" is a self-designation made by 47 million Americans, as of 2008.
- They have origins in the Spanish-speaking nations of Latin America, chiefly, whereas a small percentage traces their origins to Spain.

Clavicle
- The shaft of the clavicle acts as the origin and attachment point for numerous muscles and ligaments.
- At the medial end of the shaft the pectoralis major originates from the anterior surface, the posterior surface gives origin to the sternohyoid muscle and the superior surface the sternocleidomastoid muscle.
- Laterally the deltoid muscle originates from the anterior surface and the trapezius muscle attaches to the posterior surface at the trapezoid line.
