Anatomical Terminology Section 1.7

Do Now Try your best to write a sentence for each of the following words. When possible, use anatomical parts in the sentence. - Anterior - Posterior - Superior - Inferior - Dorsal - Ventral -

Objectives To explain relative body positions and be able to use them in describing body parts. To identify the 3 types of body planes. To locate the different body regions.

“Anatomical Position” Body is standing erect Upper limbs at sides Palms forward

Relative positions 1. Superior: 2. Inferior: “above” Ex: your nose is superior to your mouth 2. Inferior: “below” Ex: your mouth is inferior to your nose

Relative positions 3. Anterior/ventral: 4. Posterior/dorsal: “in front” Ex: your eyes are anterior to your brain 4. Posterior/dorsal: “in back” Ex: the pharynx is posterior to the oral cavity

Relative positions 5.Medial: 6. Lateral: Closer to the center of the body Ex: your nose is medial to your eyes 6. Lateral: Farther away from the center of the body Ex: your ears are lateral to your eyes

Relative positions 7. Proximal: 8. Distal: body part that is closer to a point of attachment to the trunk than another body part. Ex: the elbow is proximal to the wrist 8. Distal: Body part that is farther from a point of attachment to the trunk than another body part. Ex: the fingers are distal to the wrist

Relative positions 9. Superficial: 10. Deep: Near the surface Ex: your epidermis is the most superficial layer of skin. “superficial wound” is on this surface. 10. Deep: Describes parts that are more internal than superficial parts. Ex: the dermis is the deep layer of skin. A “deep wound” would be more problematic and possibly require stitches.

Body sections 1. Saggital 2. Transverse 3. Coronal Divides body into left and right portions lengthwise 2. Transverse Divides body into superior and inferior portions 3. Coronal Divides body into anterior and posterior portions

Guess the Planes: coronal, sagittal, or transverse?
