1A Road Map thru the Body The vocabulary of Human Anatomy Special terminology is used for position, direction, regions, and structures found in the human body.Why is it important there be exact terms for position; direction; region; and structuresThe vocabulary of Human Anatomy
2Anatomy – study of the structure and shape of the body and its parts Physiology – study of how the body and its parts work or functionGross AnatomyLarge structuresEasily observableAnatomy deals with the morphology or structure of the body and its partsPhysiology studies the function of these partsAnatomists rely on observation while physiologists employ experimentation; they both go hand in hand the functional role of a part depends on how it is constructed. In this class we will not only study the structure thru observations but deal with the function thru experimentation.Microscopic AnatomyVery small structuresCan only be viewed with a microscope
3Draw a stick-like figure, with a head, trunk, arms, and legs in anatomical position standing erect, facing forward, upper limbs at sides, palms facing forward.As the terms are discussed, designate the area or draw arrows on the paper to designate direction.
4Terms of Relative Position Superior versus InferiorAnterior versus PosteriorMedial versus LateralProximal versus DistalSuperficial versus DeepTerms of relative position are used to describe the location of a part relative to another partSuperior = toward the head end or upper part of a structure or the body; aboveInferior = away from the head end or toward the lower part of a structure or the body; belowAnterior or ventral = toward the front of the body; in front ofPosterior or dorsal = toward or at the backside of the body; behindMedial = toward or at the midline of the body; on the inner sideLateral = away from the midline of the body; or on the outer sideProximal = close to the origin of the body part or the pint of attachment of a limb to the body trunkDistal = farther from the origin of a body part or the point of attachment of the limb to the body trunkSuperficial = toward or at the body surfaceDeep = away from the body surface, more internal
6Identify the following areas on your stick figure: Area distal to the knee.Area proximal to the elbow.Lateral to the thumb.Area that is superior to the lungs.Area that is inferior to the heart.A structure that is anterior to the brain.Draw a line showing a transverse plane.642351
