Navigating the Body (Chapter 1) Flashcards
Plane of the body that divides the body into left and right halves. The descriptive terms medial and lateral relate to this plane. The motions of flexion and extension occur along this plane.
Sagittal Plane
Plane of the body that divides the body into front and back portions. The terms anterior and posterior relate to this plane. The actions of adduction and abduction happen along this plane.
Frontal Plane
Plane of the body that divides the body into upper and lower parts. The terms superior and inferior relate to this plane. the action of rotating happens along this plane.
Transverse Plane
Refers to a structure closer to the head.
Superior
Refers to a structure closer to the feet.
Inferior
Term meaning closer to the head. Utilized when referring to structures on the trunk.
Cranial
Term meaning closer to the feet. Utilized when referring to structures on the trunk.
Caudal
Term pertaining to a structure further toward the back of the body than another structure. Also referred to as dorsal.
Posterior
Term pertaining to a structure further in front of another structure. Also referred to as ventral
Anterior
Term pertaining to a structure closer to the midline of the body.
Medial
Term pertaining to a structure further away from the midline of the body.
Lateral
Term describing a structure further away from the trunk of the body’s midline.
Distal
Term describing a structure closer to the trunk of the body’s midline.
Proximal
Movement that straightens or opens a joint. This movement takes place in the sagittal plane
Extension
Movement that bends a joint or brings the bones closer together. (in fetal position most joints are in this position) This movement takes place in the sagittal plane
Flexion
This particular rotation brings the limb in toward the midline. (also only occurs at the hip and shoulder joints)
Medial Rotation
This particular rotation swings the limb away from the midline of the body. (also only occurs at the hip and shoulder joints)
Lateral Rotation
This movement involves a combination of flexion, extension, adduction, and abduction; together these actions create a cone shaped movement. (this movement is only possible at the hip and shoulder joints)
Circumduction
This movement only occurs at the axial skeleton. For example when the neck or vertebral column bends laterally to side.
Lateral Flexion
Term referring to the superior movement of the scapula or jaw.
Elevation
Term referring to the inferior movement of the scapula or jaw.
Depression
Term describing the pivoting action of the forearm. Occurs when the radius and ulna lie parallel to one another. (this movement can also occur at the feet)
Supination
Term describing the pivoting action of the forearm. Occurs when the radius crosses over the ulna, turning the palm down.
Pronation
Term that means to wander from the usual course. (lateral deviation occurs at the mandible during talking or chewing.)
