Anatomical Planes of the Body

Anatomical Planes of the Body

Second, you will consider the planes of the body. Understanding these will facilitate learning terms related to position of structures relative to each other and movement of various parts of the body.

FRONTAL (or coronal) separates the body into Anterior and Posterior parts
MEDIAN (or midsagittal) separates body into Right and Left parts
HORIZONTAL separates the body into Superior and Inferior parts
SAGITTAL any plane parallel to the median plane /

After taking a look at the Anatomical Planes, you can then view some of the terms related to the planes. These are listed in the following tables. You will notice that most of these are in pairs of opposites.

Terms of relation or position

superior (closer to the head) / inferior (closer to the feet) / reference point -- horizontal plane
posterior (dorsal) closer to the posterior surface of the body / anterior (ventral) closer to the anterior surface of the body / reference point -- frontal or coronal plane
medial (lying closer to the midline) / lateral (lying further away from the midline) / reference point -- sagittal plane
proximal closer to the origin of a structure / distal further away from the origin of a structure / reference point -- the origin of a structure
superficial / deep / reference point -- surface of body or organ
median / reference point -- along the midsagittal or median plane
intermediate / between two other structures

Human Body Tissues

Remember that levels of organization in a multicellular organism include cells, tissues, organs, and organ systems. Tissues are groups of similar cells that perform a single function, such as connecting a muscle to a bone. An organ is a group of tissues that work together to perform a complex function, such as sight. An organ system is a group of organs that perform closely related functions. (Miller and Levine’s Biology)

In this packet, we will explore numerous organs and tissues. They will bring up the four kinds of tissue often. The four major types of tissues in the human body are epithelial tissue, connective tissue, nervous tissue, and muscle tissue.

·  Epithelial tissue- includes glands and tissues that cover interior and exterior body surfaces.

·  Connective tissue- provides support for the body and connects its parts.

·  Nervous tissue- transmits nerve impulses throughout the body.

·  Muscle tissue- along with bones, enables the body to move
