Wrist is the joint distal to the elbow joint.
To show the correct direction of a vector, you need to specify the reference point or origin from which the vector is being measured, and also indicate the angle or orientation at which the vector is pointing relative to that reference point. This information can be represented using coordinate axes, angles, or directional headings.
The reference position for all directional terms is the anatomical position. This position is characterized by standing upright, facing forward, with arms at the sides and palms facing forward. It is used as a standard point of reference for describing the location or orientation of body parts.
Directional bearings are measurements used in navigation to indicate the direction or heading of an object or location relative to a reference point, typically measured in degrees clockwise from north. The four primary directional bearings are north (0 degrees), east (90 degrees), south (180 degrees), and west (270 degrees). Intermediate directions such as northeast (45 degrees) or southwest (225 degrees) are also commonly used.
Lateral is a positional term that means away from the midline of the body.
The directional term for the ears in relation to the head is "lateral." This means that the ears are positioned on the sides of the head, away from the midline. In anatomical terms, lateral refers to structures that are farther from the center of the body or a given reference point.
Proximal is the term used to say that something is closer to the trunk of the body. Example: The elbow is proximal to the wrist.proximal
The crook of the arm is the inner elbow area where the arm bends. It is often used as a point of reference for carrying objects or supporting one's arm while resting.
"Avant" means "before" in French. It can be used to indicate a point in time or position that is ahead of a specific reference point.
If left and right were the reference points, it could lead to confusion or misunderstanding when communicating directions with others who use a different frame of reference. For example, saying "turn left" might mean different things depending on where the reference point is established. Standard directional references like north, south, east, and west are more universally understood.
The bone that makes the posterior point of the elbow is the ulna. The projection at the posterior point of the elbow is called the olecranon process.
The mark cut on a stone or rock to indicate a level in a leveling survey is typically called a benchmark. It serves as a reference point for future surveying activities and helps ensure consistent measurements over time.
The wrist is located distal to the elbow. Meaning the wrist is farther from the point of origin than the elbow.
