1. Introduction to A&P

Anatomical Terms

Regional Terms, Directional Terms, Planes & Sections

Proximal means closer to the origin of the body part or the point of attachment of a limb to the body trunk. Distal means farther from the origin of a body part or the point of attachment of a limb to the body trunk. In this case, because the thigh is closer to the body trunk than the knee, the knee is distal to the thigh.


divides the body into upper (superior) and lower (inferior) portions in the horizontal plane



A transverse plane divides the body into an upper and lower portion in the horizontal plane.



divides the body into left and right parts that are parallel to, and therefore not directly on, the midline



A parasagittal section divides the body into left and right parts that are parallel to the midline.



cuts the body diagonally between the horizontal and the vertical planes



An oblique section cuts the body diagonally between the horizontal and the vertical planes.



divides the body in two equal left and right sides along the midline



The median, or midsagittal, plane __________.



The neck is included in the axial part of the body.



The head is included in the axial part of the body.



The trunk is included in the axial part of the body.



Which of the following is/are NOT included in the axial part of the body?


Anatomical Position and Directional Terms


A frontal (coronal) plane lies vertically and divides the body into anterior (front) and posterior (back) parts.



The frontal (coronal) plane divides the body into superior and inferior parts.



The appendicular part consists of the appendages, or limbs, which are attached to the body's axis.



Which of the following refers to a major body division that includes the limbs?


Anatomical Position, Directional Terms, & Body Planes


because they allow us to explain where one body structure is in relation to another



because they enable us to identify an extreme anatomical variation in a human body



Directional terms allow us to explain where one body structure is in relation to another.



because they allow us to designate specific areas within major body divisions



because they allow us to accurately describe the position of a human body



Why are directional terms so important?


The terms cranial and superior are synonymous, and they mean "toward the head end or upper part of a structure or the body; above." As such, the chin is cranial, or superior, to the navel.


The navel is superior (cranial) to the chin.



The chin is superior (cranial) to the navel.



Which of the following statements is correct?



a horizontal plane that divides the body into anterior and posterior parts



A sagittal plane is a vertical plane dividing the body into right and left parts.



a horizontal plane that divides the body into superior and inferior parts



a vertical plane that divides the body into anterior and posterior parts



a vertical plane that divides the body into right and left parts



Which of the following best describes a sagittal plane?



This is the medical term for the center region of the trunk around the umbilicus.



This is the medical term for the upper right corner of the trunk, which runs alongside the thoracic cage.



This is the medical term for the center, lowermost area of the trunk.



If you know that the appendix lies in the right lower part of the trunk, you could also say it lies in the __________.



The sternal region is superior to the umbilical region.



The sternal region of the body is __________ to the umbilical region.



This is one of the characteristics of the anatomical position.



The body is “standing at attention.”



Which of the following does NOT represent correct positioning when placing the body in the anatomical position?



The frontal, or coronal, plane divides the body into anterior and posterior parts.



The plane that divides the body into anterior and posterior parts is called the __________.
