Anatomy
|
Study of structure.
What does it look like? Where is it located? How does it relate to other body parts? |
|
|
Gross Anatomy
|
Study of structures visible without a microscope.
|
|
|
Microanatomy
|
Study of structures that require use of a microscope.
|
|
|
Systematic Anatomy
|
Study of structures organized into systems. Ex: digestive system.
|
|
|
Regional Anatomy
|
Study of structures organized into regions. Ex: head, neck.
|
|
|
Physiology
|
Study of function.
How does it work? |
|
|
Superior (cranial)
|
Toward the head end or upper part of the body. Example: the head is superior to the neck.
|
|
|
Inferior (caudal)
|
Away from the head end or toward the lower part of the body. Example: the neck is inferior to the head.
|
|
|
Anterior (ventral)
|
Toward the front of belly side. Example: the eyes are on the anterior side of the head.
|
|
|
Posterior (dorsal)
|
Toward the back. Example: the vertebral column (backbone) extends down the posterior side of the body.
|
|
|
Medial
|
Toward the midline. Ex: the nose is medial to the ears.
|
|
|
Lateral
|
Away from the midline. Ex: the ears are lateral to the nose.
|
|
|
Superficial (external)
|
Toward the surface of the body. Ex: the skin is superficial to the muscles.
|
|
|
Deep (internal)
|
Inward from the surface of the body. Ex: the heart lies deep to the rib cage.
|
|
|
Proximal
|
Toward a structure's origin or point of attachment to the trunk. Ex: the upper arm is proximal to the wrist.
|
|
|
Distal
|
Away from a structure's origin or point of attachment to the trunk. Ex: the knee is distal to the thigh.
|
|
|
Sagittal Body Plane
|
Extends along the long axis of the body, dividing it into left and right portions.
|
|
|
Frontal Body Plane
|
Extends along the long axis of the body, dividing it into anterior and posterior portions.
|
|
|
Horizontal Body Plane
|
Extends perpendicular to the long axis of the body, dividing it into superior and inferior portions.
