Question: How Do Proximal And Distal Differ From Superior And Inferior?

What is the difference between proximal and medial?

Medial refers to anything toward the center of the body.

(The opposite is lateral.) Proximal refers to a point closer to a reference point.

(The opposite is distal.).

How do you use proximal and distal in a sentence?

Proximal and Distal Examples: The wrist joint is distal to the elbow joint. The scaphoid lies in the proximal row of carpal bones. The knee joint is proximal to the ankle joint.

How do you use distal in a sentence in anatomy?

Distal sentence examplesThe distal portions form the muscles of the tentacles. … Bleeding from a vein is of a darker colour; the flow is steady, and the bleeding is from the distal end of the vessel. … The longitudinal system is discontinuous, and is subdivided into proximal, medial and distal portions.More items…

Is dorsal a top or bottom?

The dorsal (from Latin dorsum ‘back’) surface of an organism refers to the back, or upper side, of an organism. If talking about the skull, the dorsal side is the top. The ventral (from Latin venter ‘belly’) surface refers to the front, or lower side, of an organism.

What body parts are proximal?

Proximal means nearer to the center (trunk of the body) or to the point of attachment to the body. If another reference point is given, such as the heart, the proximal point of another organ or extremity is the point closest to the heart, central rather than peripheral. Proximal is the opposite of distal.

What are the 4 body planes?

The anatomical planes are four imaginary flat surfaces or planes that pass through the body in the anatomical position. They are the median plane, sagittal planes, coronal (frontal) planes and horizontal (transverse) planes (figure 2).

What body parts are medial?

Medial means toward the middle or center. It is the opposite of lateral. The term is used to describe general positions of body parts. For example, the chest is medial to the arm.

What are the two types of risk factors?

In summary, the study of risk factors will benefit from a clear definition of terms where there is an unambiguous distinction among correlates, fixed markers, variable markers, and causal risk factors.

Why is the elbow proximal to the wrist?

Explanation: Since the words proximal and distal refer to distance, and your question is posited regarding the elbow in connection to the wrist and shoulder, the length of the humerus being more than that of the radius and ulna makes the elbow closer to the wrist.

Why are directional terms so important?

Why are directional terms so important? Because they allow us to explain where one body structure is in relation to another. Directional terms allow us to explain where one body structure is in relation to another. The breastbone is ventral to the spine.

What is the difference between distal and proximal?

Proximal – toward or nearest the trunk or the point of origin of a part (example, the proximal end of the femur joins with the pelvic bone). Distal – away from or farthest from the trunk or the point or origin of a part (example, the hand is located at the distal end of the forearm).

Is the knee proximal or distal to the hip?

The knee is proximal to the foot. Moving distally from the hip brings you to the thigh. The foot is distal to the knee.

What is an example of proximal?

Proximal: Toward the beginning, the nearer of two (or more) items. For example, the proximal end of the femur is part of the hip joint, and the shoulder is proximal to the elbow. The opposite of proximal is distal.

Is the knee proximal or distal to the ankle quizlet?

The hips are superior/inferior to the shoulders. The shoulders are medial/lateral to the spine. The knee is distal/proximal to the ankle.

What is the difference between superior and inferior?

Superior refers to ‘above’ while inferior refers to ‘below’.

What is a proximal risk factor?

A proximal risk factor is a risk factor that precipitates a disease, such as BPD. They represent an immediate vulnerability for a particular condition or event. Sometimes proximal risk factors cause or shape an event.

What is a proximal influence?

Proximal influences refer to current individual, social, or economic resources; whereas distal influences are defined as past personal experiences in cumulative life events or achievements (e.g., education) and historical events (Brown & Anderson, 1991; Martin & Martin, 2002; Wheaton, 1994).

What are proximal determinants of health?

The proximal determinants, which act on both micro and macro levels, often include lifestyle or behavior (e.g. alcohol, fat, tobacco, fruit and vegetable consumption), and socioeconomic environment (including macro-economic measures such as wealth), demography (e.g. elderly proportion of the total population), physical …
